White Grub Control Alternatives

White Grub Control Alternatives

It is very difficult to use an IPM (Integrated Pest Management) approach to white grubs in turfgrass.  Turfgrass often has a very high value – either monetary value (golf courses and sod farms) or aesthetic/emotional value (home lawns).  White grub infestations are highly variable from year to year and from place to place.  Damage is spotty, localized and impossible to predict.
Monitoring, one of the keystones of IPM is not practical for white grubs under most circumstances.  Inspection for grubs requires cutting and lifting flaps of turf and looking for grubs below the thatch level.  This is difficult, time consuming and potentially damaging.  Research has indicated that the number of samples necessary is too large to be practical. 
Studies at Cornell University have shown that over 70 percent of all grub control treatments were applied needlessly because there were no grubs in the lawn. Many homeowners are frightened into applying grub controls because of advertisements on TV, in plant centers, or because of horror stories they have heard about grub damage. Most grub treatments are not only expensive but hard to justify from an environmental standpoint.
There are 3 approaches to grub management in the home lawn, depending on your tolerance for damage, comfort with pesticides and willingness to spend the cash.
#1. The Golf Course Approach:  Treat every part of the lawn, every year because you might have white grubs and heavy use of high-price insecticide is preferable to ANY white grub damage.  The available insecticides for grub prevention are imidacloprid (Merit®, Grub-Ex®) and halofenozide (Mach 2®, Grub-B-Gon®).  These must be applied before early August to prevent damage.  A compromise modification of the Golf-Course Approach is to treat only those areas of previous damage.  Grubs tend to return to the same areas in successive years, so it is logical to treat the areas where you had grubs last year or the year before.
#2.  Wait-And-See Approach.  Watch the lawn carefully during August - September for early signs of damage (wilting, turning brown).  Apply a curative insecticide such as trichlorfon (Dylox, Bayer Advanced 24-Hour Grub Control) only where needed and when needed.  The risk is that you might still lose some sod, especially if summer rainfall or irrigation keeps the grass growing and vigorous through July and August.  Damage symptoms may not appear until after it is too late for effective treatment (late September through late October).  Unfortunately, raccoons and skunks are much better at locating grub populations than we are and the first hint of a grub problem in your turf is likely to be that your lawn was "plowed" by varmints overnight.
#3.  The Do-Nothing Approach.  Count up how many years you DID NOT have grub damage.  Divide the cost of replaced sod by that number of years.  If the yearly-averaged cost of sod is less than the price of insecticide, do nothing and take your lumps in the occasional year when damage occurs.  This approach is much easier to follow if your attitude is "it's just grass, anyway."
White grub management decisions are difficult and frustrating.  There is no one right answer for everyone.

CA 6 Essential Tips for Managing The White Culprit in San Jose

The Signs of the Times, You Might Have White Grub Worms

June is the beginning of summer, it also signifies the arrival of the June bug – the beetles that buzz around and seemingly wreck into everything that crosses there path can leave a mess. But the beetles of June that aren’t so fortunate as some, can emerge later, potentially causing much bigger landscape challenges, more than than a few dead insects on the pavement.

They lay there eggs like clockwork

June bugs lay their eggs like clockwork that ultimately evolve into the white grub worm, which has been known to severely cause damage on lawns and ornamental flower beds in and across Bay Area Landscapes. The grubs live below the soils surface and mature at about a five inch depth below and usually thrive in well-nourished soil for about a period of one year prior to emerging from the ground as the June bug.
While a sparse group of white grubs can actually be beneficial to lawn, by providing necessary oxygen for aeration and moisture, they can wreck lawn areas and do harm to the root system of plants, especially in uncontrolled environments. They have a tendency to be most prevalent in the Months of July and August causing the most visual damage at this time of the year.

They Feed on Lawns and Flowers

White grubs like to feed on cool season grasses, some of which include: perennial rye, Kentucky blue grass and tall fescue doing significant damage to their root system.

Identifying the White Culprit

Grub worms typically have a plump, white body with an orange or red head , grayish in color at the end of its body. Parts of their body are translucent in color and have a curled shape.
Also, be aware of Cut Worms and Army worms. Army worms are narrow and straight in length, a more dark color tone, and can be revealed with some yellow striping. Cut worms have a tendency to curl up like grubs but are tannish or green in color and may have obvious striping similar to Army worms. They can also be problematic causing root damage to your ornamental landscaping, flowers and turf areas.

The aftermath of the Damage

  • Landscapers with white grub damage may notice patches of dead grass. In addition, you may see raccoons and other wildlife like Skunk or other Pests digging up your lawn to get to the grubs. A high population of white grubs can result in grass that can be rolled up like carpeting. Furthermore, grass may feel bouncy as you walk across the lawn, according to the University of Davis. Healthy, densely growing grass with a moderate white grub population usually recovers from the damage.

How to Test for Grub Worms

  • Cut out 1 square foot of turf from the lawn with a masonry trowel to determine the severity of your white grub problem. If you find more than 10 grubs in the grass or dirt, consider options for treatment. You can control grubs through cultural practices if there are less than 10 in the turf patch. Landscapers may be tempted to treat grubs in the spring. However, late-summer pesticide applications are more effective because grubs have just hatched.

Cultural Treatment

  • Beetles look for moist soil to lay their eggs, so a dry lawn in the late summer is essential. Also, restricting water on your lawn will dry out the eggs. Gardeners can also check their thatch layer to see if it is more than 1/2 inch. If it is, it creates an optimal environment for grubs. If you decide to use pesticides, it is better to remove thick thatch so that the chemicals can be absorbed into the soil. Dethatch the lawn to remove grubs' environment and prepare the lawn for potential pesticide use.

Natural and Sustainable Landscaping Treatment

For those choosing a more natural and sustainable landscaping approach , there are several options available. All of which are considered safe and effective. These include milky spore, neem oil, and nematodes – available at most garden centers.
  • Milky spore is a disease that can effectively treat lawn grubs and is environmentally safe. Spores are applied to affected lawn areas, infecting lawn grubs as they feed. Once the grubs die and decompose, additional spores are released into the soil, which helps prevent further infestations.
  • Neem oil is a botanical pesticide containing insecticidal properties. Neem oil works more as a repellant against Japanese beetles and lawn grubs – inhibiting egg laying, growth and feeding. Neem oil is mixed with water (as directed) and sprayed onto affected lawn areas.
  • Nematodes are also used as natural grub treatment. These tiny, soil-dwelling worms release bacteria into the soil that infects and kills lawn grubs. Nematodes are available in liquid form or mixed with water and sprayed onto affected areas.

Chemical Treatment

  • Pesticides that contain imidacloprid or halofenozide should be applied between Aug. 1 and Sept. 15, according to local Universities. Apply the pesticide in the most severely damaged areas of the lawn. Water the pesticide after applying with 1/4 to 1/2 inch of water so that it sinks into the soil. You can also forgo watering if afternoon showers are expected. Reapply the pesticide as recommended on the label.
Once you know how to detect grub worms and how to get rid of grub worms, you’ll be better equipped to treat the problem more effectively.

A Few Grub Worms are tolerable in the Landscape

It’s normal for grub worms to present themselves in bay area landscaping, especially those in favorable conditions, but don’t panic. In the summer months, it’s easy to be overly concerned about grub worm damage; although in many parts of Northern California they are not as active as one might think. A good practice is to begin treatments in July-August.
So please don’t worry; a few grub worms in the lawn aren’t worth losing sleep over. Just control them so they don’t get the best of your landscaping.

Grub Control for Lawns


Brown, dead patches of grass are tell-tale signs of lawn grubs. These pests live a few inches underground and feed on your turf's roots. Often grubs go unnoticed until the damage is done. Don't despair, though. Proper lawn maintenance, preventative measures and, if needed, pest control treatments, can make your lawn green again.

Identifying grubs

Lawn grubs are larvae of various beetle species, such as Japanese, June, Asiatic and Masked Chafer beetles. They're often called white grubs, because the larvae are white with a brown head. White grubs are characterized by a C-shape, grow to one-half inch to an inch long and have six legs.
Adult beetles lay their eggs a few inches below your lawn's surface in late spring. A few weeks later when the eggs hatch, the larvae start growing - and eating your lawn's roots. The damage can continue through the summer.
With autumn's cooling temperatures, grubs move deeper in the ground where they spend the winter. When spring arrives, grubs migrate toward the surface to begin feeding again on the grass. When adult beetles mate and lay even more eggs, the cycle starts again.

What to look for

Grubs live a few inches under the grass. They eat the turf's roots, causing brown or yellow dry patches. It's often said you can pull that grass back like a carpet. Grub damage also makes the lawn more likely to die during hot, dry spells. Additionally, you may notice grub-loving birds feeding on your lawn, or signs of gophers and moles.
Homeowners can be fooled, though, by grass that looks healthy. Infested areas can remain green even as grubs munch away at the roots. The damage appears the next spring when grub-infested areas don't green up.
Grubs often re-infest the same areas year-after-year. Some patches are more attractive to beetles than others. They like open areas with consistently warm, moist soil.

Prevention and treatment

Dig into the soil of one of the bare spots. If you discover small white C-shaped creatures, you have grubs.
If you find only a few grubs, adequate water and fertilizer can help the turf recover, then reseed or resod the affected areas. A few grubs per square foot aren't troublesome to an otherwise healthy lawn. Treatment typically is recommended when eight to 10 grubs per square foot are discovered.
Proper yard care can help prevent grubs. Reduce lawn stress by planting an appropriate turf grass variety for your growing conditions. Take into account the soil type, sun exposure, climate and lawn use. Ask a Southern States lawn expert for suggestions about grass seed varieties that are best suited for your lawn.
Mow and water regularly. Deep turf watering is preferable to daily watering. Allowing your lawn to dry out between waterings turns it into an unattractive environment for grubs.
Because grubs encompass different beetle species, pest control results vary based on the product. Some are designed for prevention, others for treating existing grubs. The application timing matters too. Some species are best treated at the adult stage; others when the larvae are feeding close to the lawn surface. Because of their underground habitat, aeration can be beneficial when used in conjunction with pest control.
When choosing a treatment method, ask your local Southern States dealer for advice on grub control products.

The organization says in its report that more than two billion people actually complete their own food to eat insects , but they say that '' shit '' shown by the consumer towards the western eat insects still constitutes a barrier to the spread of the phenomenon in many Western countries .The report stated that the wasps , beetles and other insects are not properly exploited as food for humans and livestock , adding that the insects are considered propagating '' methods of addressing the problem of food security . ''The report also '' insects are everywhere , and they reproduce quickly . Vllhacrat growth rates and shift diet high in addition to the low vulnerability of the environment. ''The authors of the report refers to the high nutritional value of insects , with high proportions of proteins, fats and minerals.They say that eating insects is '' very important , especially as an addition of food for children who suffer from malnutrition . ''The report stated that the insect has a very high efficiency in converting food consumed to meat man can be addressed , Vsrsar night , for example, consumes 12 times less food to produce the same amount of protein compared to cattle .In addition, the insects do not produce the same quantities produced by livestock of gases harmful to the environment , driven emissions of ammonia , for example, much less insects in farms than it is in the pastures of cattle and other animals that eat human pigs .The report suggests the food industry to strive to raise the profile of the insects '' and '' make it more receptive to the part of consumers - especially in Western countries - through annexation in cooking recipes and add them to the lists of meals in restaurants .The report indicates that some of the insects are considered lavish meals in a number of countries , for example South Africans look to some types of larvae bed as luxury cuisine and are therefore sold at high prices in that country .He says that most edible insects are caught in the woods , calling for the pursuit of improving the means of production of insects that are used for livestock feed .And concludes that '' the consumption of insects is widely used as animal feed is technically feasible , and that a number of companies in many parts of the world are already doing it .

the white grub



GRUBS
In order to control the enemy, you must first understand it. This will help you create a plan of
action for battling the white grub and its alter-ego, the Japanese beetle. Declare war on them
before they wreak havoc on your lawn, ornamentals, and trees.
Meet: The Grub. Grubs are one of the most common lawn pests in the US and also one of the
most damaging to grass. The white grub is the larval stage of a more commonly known pest, the
Japanese beetle. The larva is approx. 1/2 inch long and is off white in color with a brown head.
According to Lance Walheim, Bayer Advanced expert and author of Lawn
Care for Dummies, these pests are so common in lawns that consumers now
spend more than $100 million annually to control them.
What is a Grub Worm? The grub worm is not exactly a worm, like your friend, the earthworm.
Grub worms are basically beetle larvae, or the babies of those beetles. Unlike earthworms that
fertilize your soil to make your plants and flowers healthy, grub worms ruin them by munching
on the roots of your plants, flowers, and grass in your lawn or garden. A healthy lawn can handle
a few grub worms in the soil and will do little or almost no apparent damage. After the eggs of
the beetle hatch and turn into larvae, they tunnel underground and start eating roots they see.
However, when there are more than 15 to 20 grub worms per square foot in your lawn or garden,
then that is a real problem. You surely will notice that you have a grub worm problem when the
condition of your lawn radically deteriorates.
Signs of Grub Worm Infestation Grub worms are real pests and can cost you a lot when they
damage your favorite (and expensive) plants and flowers. Here are some of the common signs of
grub worm infestation:
Droopy leaves
Green-gray or brown patches on your lawn.
Grass easily“peels” off.
Ground feels spongy to the feet.
Sudden death of plants, grass, or flowers.
Appearance of moles, armadillos, or other pests in your lawn.
Grub Worms: Why you should Get Rid of them Grub worms feed on the roots of plants and
the other things planted in your garden. Such actions severely affect them and eventually lead to
wilting, or the death of these plants. Roots of plants are very important organs. They are the ones
responsible of absorbing water and other essential nutrients from the soil to make the plant grow.
With them damaged or eaten up completely, the plant has no other means of absorbing nutrients
and water from the soil. When the roots are damaged, it may not be able to absorb the water and
nutrients the entire plant needs to function properly, that is why you see your plants, flowers, and
your grass droop, turn brown or gray, and eventually die. Aside from damaging your garden,
when there is a serious grub worm infestation, it will attract other animals or pests that feed on
them, making the problem even more serious. Examples of such creatures that eat grub worms are
armadillos, gophers, and moles. Though these creatures eat grub worms, they leave nasty burrows
and instantly damage your lawn or garden.
Eliminating Grub Worms? What to Do? Beetles usually lay their eggs during early summer.
After these eggs hatch, they turn into nasty pests, known as grub worms. Grub worms then tunnel
underground and feast on the roots of plants and grasses until the winter or fall season. If you will
notice, this sort of problem is like a cycle and it seems that there isn't a permanent solution to get
rid of them. It is a cycle because these grub worms will soon mature and turn into adult beetles,
and again, laying eggs in your lawn or garden that soon will become grub worms.
Natural way to Getting Rid of Grub Worms Here are the steps to rid your lawn or garden of
these grub worms naturally:
1. You already know you have a grub worm problem, now you have to determine when the
beetles start laying their eggs.
2. Nematodes are the natural enemies of grub worms. They infest and kill these pests.
However, they are only effective on young larvae. This is where your research will come
in. Once it is the season of beetles to lay their eggs, purchase nematodes from a gardening
store and follow the instructions indicated. Spray on your lawn or garden.
3. To offset the damage caused by the grub worms, keep your garden or lawn watered.
Abundant water will make the damaged roots easily absorb water.
4. Robins and other songbirds love grub worms. Have them in your garden and you will
have to worry less about those pests. This is probably the best long-term solution you
have.
Grub worms are serious pests especially to those gardening enthusiasts. These solutions will help
you get rid, or at least keep the grub worms under control.
We carry a product in the nursery called Bayer Advance Grub Control. This is effective in killing
the grubs or we can send our chemical crew out to treat for you using industrial strength
chemicals. Give us a call today at 407-2727 for more information.

Treatment for Grub Worms



Treatment for Grub Worms
Treatment for Grub Worms
Appearance
Grub worms have a white segmented body with a brown head and six scraggly legs at the front of the body. Their backside is usually a dark brown to black under stretched skin and looks a lot like a reservoir of fecal matter, often bulging from their feeding indulgences.
Damage
Noting damage caused by grubs is pretty easy. They feed on turf roots, so grass they are feeding on turns brown and dies. Main feeding times are right after hatching from eggs in August and September, for about 3-4 weeks before they hibernate for the winter. After spring temperatures start to rise, they will begin feeding on turf roots again for a few weeks as they build up strength to morph into beetles.
If you have browning spots in your lawn, check for grubs by pulling up the grass. If the turf comes up like a piece of carpet, then you likely have a grub problem (you’ll probably even see a few when you lift the grass up).
Another sure sign, if you live near a wooded area, is that your yard will suddenly have holes overnight. This is from creatures like skunks, raccoons, armadillos, birds and other animals that love the juicy taste of these nasty little worms.
If you aren’t seeing a lot of damage, but know that you had a serious Japanese Beetle problem last summer, then you can still check to see if their larva are around by digging. Dig one square foot out of your lawn about 4 inches deep. One or two grubs in that space aren’t really cause for concern or treatment. However, if you’re seeing 4-7 grubs or more in a square foot of soil, you’ve probably got a problem on your hands.
Preventative Maintenance
Living in an area with a large population of Japanese Beetles in the past few years, it stands to reason that those of us in the Midwest (Oklahoma, Missouri, Arkansas, etc.) likely have grubs in our soil. One step you can take is to apply insecticides regardless of whether you know you have a problem or not. It’s sort of like having insurance on your turf – your treating the possibility of a problem before it actually becomes a problem.
Treatment
Regardless of whether you’re treating the lawn for preventative maintenance or know that you have a grub problem, the best time to treat for them is during late summer and early fall, when they are feeding the most. They get too deep in the soil during winter hibernation and are so large and on the verge of becoming beetles that treatment is virtually ineffective during winter and spring months. You want the grubs to have hatched (around August) and to be young and venerable.
As mentioned, insecticides are effective at treating grubs. Keep in mind, however, that they only last 2-3 weeks and may require additional applications. These insecticides are easy enough to find at your local hardware or lawn care store – they will be clearly marked for grub treatment. They all seem to work on an equal plain.
Natural Alternatives
If you prefer to use a natural grub treatment, there are some effective options available. Milky spores, available at your local lawn care store, are one option. You simply apply the spores to the lawn and the grubs ingest them while feeding. These grubs die and spread more spores, killing off other grubs.
Neem oil is a natural pesticide, mixed with water and applied to the lawn. It inhibits the egg laying process in regard to Japanese Beetles, and also inhibits the hatching, growth and feeding process of the grubs already established.
You can also add nematodes to your lawn – a small worm that releases bacteria into the soil that won’t affect your plants or turf, but kills grubs. These worms are so small that they come in a liquid form that is typically mixed with water and sprayed on your lawn.

Controlling grubs in garden and lawns


We have a native grass grub here in NZ that comes from the scarab beetle. They are the reason that the birds, especially blackbirds mess up lawns in winter as they dig down to get these grubs. The local university landscaped grounds have large patches of decimated lawns each year as the birds have a field day. They need a good lecture!

In other countries, grub worms or white worms are similar and can be the grub of several beetles, most commonly the iridescent, brown and green Japanese beetle. The grubs hatch about mid summer and the beetles fly around and eat leaves, particularly of roses, some fruit trees, grapes, maples and many other leafy plants and weeds.

Over 4-6 weeks female Japanese beetles go through many cycles of eating, mating then burrowing deep into the soil to lay eggs, particularly in grassy hills, paddocks and lawns. In late summer to autumn/fall, the eggs develop into larvae (grubs) and wriggle upwards to feed on plant roots and other organic soil contents. Once the grubs have eaten enough and are mature, they then burrow down into the soil to overwinter.

When the soil is warm enough in spring, the grubs head upwards again, pupate into adults (beetles) and take off to feed on leaves.

Milky Spore Disease (Bacillus popilliae), is a recognised control for grass grubs/grub worms/white worms and can be bought online or in garden stores. Soak it into the grub infested soil at their feeding stage, and the grubs ingest it, whereupon the bacteria become alive and cause the grubs to starve and die. These bacteria stay in the soil, and in fact most soils already have some Milky Spore bacteria in them, so if you add more it helps control these grubs.

Other control methods are Beneficial Nematodes and natural predators like parasitic wasps, birds, many good beetles, and even ants will seek out the eggs. Neem oil is also recommended for grubs, but it although it's natural it will kill other insects, so don't use it on your vegetable or flower garden, only use it sparingly on lawns if you really have to.

A few grubs will not be a problem and not worth the effort and challenges to control and kill them because more will always fly in each year from outside areas. If you find one or more grubs in each handful of soil, that's getting to be an infestation which may need action. A popular control method with many people is to simply go out at night with a torch and pick off the beetles from plants and squash them or flick them into a bucket of soapy water. Check the tops of bushes and plants where they congregate and start their feasting

How to get rid of Grub ?


What to Grub
 You can fool grub worms as a type of worm. But, in fact, they are the larval stage of certain beetles as the Japanese beetle, Oriental beetle, Asiatic garden beetle, adult beetles etc wander in the garden and feed on plants during the early summer. Around July and August, these insects lay their eggs deep in the earth, in the wetlands of the lawn and garden. In a few weeks, the eggs hatch and develop into larvae and larvae are called grub worms. They are plump little worm-like creatures that sport a C-shaped body with a red head and dark back. Grass grub worms feed voraciously on roots and in the process can damage the lawn. Similarly, they feed on the roots of garden plants, causing their death. Even though, they begin to feed as soon as they hatch, grub worms reach their full size in a month and those of this stage would be the source of potential harm to the plants.

Before the advent of winter, they move deep into the soil to hibernate and pupate in May. They emerge as beetles in early summer. Some of these larvae can emerge in spring and feed for a while before pupation stage. But this time, the power is not to cause great harm to plants. The presence of worms in the headless lawn or garden can attract skunks, raccoons, armadillos, moles, etc. These animals can dig in the lawn and garden, while seeking to grub they devour.

How to get rid of Grub
 While grub worms in small numbers may not happen much harm to your garden plants or grass, in large numbers, they can be a serious threat. It has been observed that regular watering, mowing and fertilizing normal can prevent possible damage that may be caused by worms headless. But if a square foot of soil in the lawn or garden has more than five grub worms, then we must seek measures to get rid of them. Even though there are different types of pesticides that can be used to eliminate them, it will always be better to try natural methods of fight against pests, as a first line of defense. If the infestation is not so great, then try to attract predators to grub, like the birds (blackbirds). Try frequent watering, so that the grass recovers lost root.

How to Get Rid of Grub Worms



How to Get Rid of Grub Worms

Grub worms are a serious lawn pest that can do incredible damage to your turf if left untreated. If you have brown patches in your grass, you likely have an infestation. Grub worms eat the roots of your grass and can be controlled if you follow the correct procedures. Does this Spark an idea?

Instructions





    • 1
      Know how to identify grub worms. They are white with a red head and a dark rear-end. They are C-shaped and usually about the size of the tip of your thumb.
    • 2
      Call your local Agricultural Extension Service and ask when grub worm eggs are typically laid and when the grubs are likely to be active in your area. You will find the phone number in the government section of your phone book.

    • 3
      Sample your yard in the month the eggs are laid and again in the month the grubs are most active. To sample your yard for grub worms, cut three sides of a 1-foot square of grass with a shovel and lift up the grass to make a flap. If you see more than five grubs, treatment is necessary.
    • 4
      Purchase beneficial nematodes from your local gardening center. These are microscopic organisms that feed on larvae. Mix the nematodes with water as directed on the package, and spray your grass with the mixture.
    • 5
      Keep your lawn lightly-watered to help offset the root damage caused by grub worms.
    • 6
      Attract worm-eating birds like robins and other song birds to your backyard. They are typically fond of eating grubs for breakfast.

The EU plans to spend $ 3 million euros (about 3.95 million U.S. dollars), to study the feasibility of insects as a protein alternative sources, the research program will be finalized this year. The food experts said that if the insects as a protein alternative sources of Europeans, "camouflage" of insects. Insect "food" can act as Hamburg, as well as other fast-food additives. The British Food Standards Agency, said in referring to the research program: the UK and other EU countries and not insects as food traditions It is estimated that about 25 million people around the world often edible food add insects Although many insects are pests, but the Food and Agriculture Organization of the United Nations or of edible insects is full of interest, and is committed to it as a highly sustainable source of nutrition. " Some earthworm protein content is three times that of beef, the four crickets calcium content will be comparable with a glass of milk. Islands Restaurant London chef Daniel - Kerry Washington, said: "If the insects from entering the human food chain, they may have to go through 'camouflage'. Food manufacturers seem should be described as animal-based protein, after all, not many people are willing to buy locusts Hamburg. "Kerry Washington ants, grasshoppers and bees made food, entertain guests from all directions.

The Treehugger website that: "The research and development of insect-based food additive used to increase the protein content of burgers and chicken nuggets, This is not hard to imagine things. Chain stores the name of 'higher levels of protein', 'healthy fats ', and of' ecological Hamburg 'slogan sales use hamburger meat made of treated insects. " 80% of the countries in the world, insects as food, human regular consumption of more than 1000 kinds of insect species. And livestock, insects only need a small space, feeding, use of natural lighting, garbage, paper and algae can act as feed in a closed building. Prior to this, the United Nations and the European Union in favor of the development of insect food practices for addressing the food shortage. Some scholars believe that the economic and environmental costs faced by raising livestock means turning to the insect will become an inevitable approach. It is estimated that by the end of this decade, edible insects will become very common. Wageningen University Professor Marcel - Dick said: "What is most important is to let people be psychologically prepared for the gradual acceptance of the idea. Since 2020, left to our choice is not much."

grubs biological learning its comprehensive prevention


Soil insect grubs biological learning its comprehensive prevention and control measures
grub worms treatment

Grubs is a Coleoptera project chafers, Branch larvae general term. The chafers their feeding habits can be divided into phytophagous, the dung feeding habits, saprophagous three categories. Herbivorous species and Rutelidae Melolonthidae some species, the occurrence of the heaviest widespread damage.Host phytophagous white grubs mostly Diet miscellaneous dicotyledonous and monocotyledonous food crops can often damage the same kind of grubs, a variety of vegetables, oilseeds, taro, cotton, forage, as well as flowers and fruit, forestry sowed the seeds and seedlings.The damage characteristics larvae lifelong inhabit soil, eating just sowed the seed, root, roots, tubers, and seedlings, causing Seedlings Deficiency off ridge. Adult eating harm fruit trees, trees, leaves and flower. Is a widely distributed, re-infestation of pests.The morphological characteristics of the body mast bend near the C-shaped body is mostly white, some yellow white grubs. Body wall is softer, more wrinkled. Surface sparsely fuzz. The head is large and round, brown, or reddish-brown, Health symmetrical setae, often minute feature. Three pairs of thoracic feet, general hind longer. The important feature of the abdomen 10, 10 known as the hip section on Health bristle, the number and arrangement is also minutes.Living habits grubs years old algebra species varies from place to place. This is a class of long insect life history, generally a year generation, or 2-3 years a generation, elderly 5-6 years a generation. Big black Melolonthidae two years, a generation the the Diablo Melolonthidae, patina beetle year generation of Xiaoyun spot Melolonthidae Qinghai four years a generation big chestnut Melolonthidae in the Ganzi region need 5-6 years generation. Of third instar grubs. The shorter 1,2 instar, 3rd instar longest. Lifetime habitat adobe grubs, and its activities are mainly related to the physical and chemical characteristics of the soil and the temperature and humidity. Year activities of the optimal average soil temperature of 13-18 ℃, higher than 23 ° C, that is gradually transferred to the deep soil, soil temperature to fall down to the appropriate range of its activities, and then moved to the topsoil. Grubs damage orchard nursery, seedlings and other crops is heaviest in spring and autumn.Prevention and control measures(1) Biological ControlGrubs few natural enemies can sometimes be large parasitic wasp parasites, sometimes the disease can reduce their number. The survey found that bacteria several species of the genus Bacillus can be infected grubs, this disease is usually referred to as "milk disease", for some types of grubs specific insecticidal activity, such as the June Melolonthidae. "Milk sickness" pest packaging treatment, used as a commodity to combat the beetle larvae. A treatment available Bacillus bacteria grasses, grubs and other larvae after planting. Warm-blooded animals such as moles, skunks, and some birds the grubs hazards have a restraining effect, but the losses caused by the damage caused on the lawn grubs.(2) manual controlCapture can be used to reduce or inhibit the populations of adult or larvae of beetles. The best method of capture is to capture the different gender or pheromone adults in addition to food trap as bait. Can also be directly with the sex pheromone trapping. These capture method has been market-oriented, and is used to reduce the number of beetles and ultimately reduce their spawning and grubs hatch. These capture method purposes the Zhongxia Cheng worm appears.(3) chemical controlThe grubs chemical control strategies include: lawn destruction before the advent of the use of preventive measures.A. Seed treatment: early prevention and treatment in 1970 grubs chemicals are still in force. Water-insoluble, and a broad spectrum of organic phosphorus.① 25% the microcapsules release agent parathion (1605), the main control grubs, mole crickets; wireworms and to rid of the seedling stage vermin.② 50% phoxim main control grubs, mole crickets, wireworms.③ 25% phoxim microencapsulated sustained release agent, the main control grubs, mole crickets, wireworms.④ 20% or 40% the methyl isofenphos EC, the main control grubs, mole crickets, wireworms and to rid the seedling stage pest.B. Soil Treatment: sowing and grubs hazards between longer duration, should be considered for soil treatment (ie applicator toxic soil), the soil treatment dosages roughly as follows:① the phoxim toxic soil, control grubs. Per hectare with 50% phoxim EC or 25% oct sulfur instantaneous microencapsulation sustained-release sentence 1.5kg watered 22.5ks, mixed with fine soil or sand 225kg applicator after plowing.(2) parathion toxic soil, the main control grubs also to rid of mole crickets, wireworms. The EC, the microcapsules release agent formulated toxic soil ① The same way.(3) the methyl isofenphos toxic soil, the main control grubs also to rid of mole crickets, of wireworms and seedling pests. The same way as ①.④ phorate granules (3911), the main control grubs, also Kaneharu the other soil pests and seedling pests. The same way as ①. The irrigation facilities phoxim toxic soil grubs hazards or with phoxim toxic water, the victim grass near IRRIGATING.
