Fighting the larvae of the May beetle on strawberries

Fighting the larvae of the May beetle on strawberries

It is rather difficult to get rid of your garden from the larva of the May bug. These pests enjoy the roots of any plants with pleasure, but they enjoy a special love with strawberries — they can kill the entire bed in a short time. Let’s find out sooner how to save strawberries from the larvae of the May beetle.

Means of combating the larvae of the May beetle

In the first year after hatching eggs are weak and no particular danger. But by the next season they have become a real disaster. The larvae of the May beetle eat with great pleasure the roots of the strawberry, leading to the death of bushes.

The struggle with the larvae of the May beetle on strawberries boils down to the following measures:

  1. Soil digging with manual removal of fat white larvae. This method is the most effective. Do this in the spring and autumn, and you need to dig deep enough.
  2. When the digging is impossible, you can plant a white clover on the site. Due to its vital activity, it makes the soil unsuitable for finding larvae here.
  3. Strawberries can be watered with a solution of water with ammonia (20 ml per 10 liters of water).
  4. In the aisles make deep grooves (up to 40 cm) and fill them with «Decis» or «Carbophos».
  5. Another proven way how to deduce the larva of the May beetle from strawberries is to pour under the bushes a solution of onion peel (100 g per 10 liters of warm water, insist 3-5 days, then dilute 1: 1).
  6. A good way is to use the «Nemabakt», which is contained in the finished biogrut. In this case, you need to monitor the proper storage of biograft at the point of purchase.
  7. Help in the fight against the larvae of insecticide «Aktara», «Zemlin», «Rehabilitation» and so on.

For a more effective struggle with the larvae, one should also pay attention to adult individuals — May beetles. To reduce their population can be planted on the site elder, lupine, turnips or turnips. Traps in the garden with sweet water will also help.

Pest of forests and gardens Maybug

The Chafer beetle, or Melolontha khrushch, belongs to the class of beetles. It belongs to the large family of lamellae due to the characteristics of the antennae. They have a beetle crowned with a plate mace.

The biological characteristics of the beetle

May bug females are able to lay up to 30 eggs in the soil. For the hatching larva, humus serves as food in the initial period of life, and then all the living and dead parts of the roots. Larvae live and move freely in the ground, looking for food. Three years later, in May, the developed new adults are selected to the surface. Leaves of trees are devouring. They cause irreversible damage to agriculture and forestry.

May bug larvae: fight

Morphology

  • The chafer beetle has a thick, strong body, with well-developed legs and two pairs of wings. Elytra hard, chitinous. Hiding behind them are the rear flying webbed wings with veins.
  • The pygidium, or end of the abdomen, is not covered by wings. The body is divided into three sections — head, chest and abdomen. The abdomen, consisting of 8 segments, is in a fixed connection with the chest.
  • 5 segments of the walking leg are connected movably. On the last segment is a claw. Each segment of the chest carries a pair of legs — only 3 pairs. The insect clings with its feet to the bark and leaves, digs holes in the soil.
  • The mouth apparatus is gnawing. An adult insect eats leaves. Once in the stomach, the food is rubbed with chitin teeth intended for grinding. In the intestine, the final digestion and absorption of food takes place.

  • The circulatory system is represented by the heart in the form of a blindly closed tube and aorta, and is open. A fluid that circulates freely in the body cavity is called hemolymph. Washing the internal organs, supplies them with nutrients.
  • The respiratory system consists of 18 spiracles located on the chest and abdomen of the beetle. Oxygen enters the spiracles, then branching trachea. Then it enters all the cells of the body.
  • Malpighian vessels, thin tubes extending from the food canal, perform an excretory function.
  • Breeding system. The female genitals are paired ovaries, passing into the tubular oviducts, which has a common excretory channel through which the eggs exit. The genitals of the male consist of 2 testes, united in the ejaculatory canal.
  • On the head is a pair of faceted eyes. The organs of smell are represented by plates located on the antennae.
  • Nervous system in the form of the supraglottic and subpharyngeal nerve node and abdominal nerve chain

Beetle species

On European territory, as well as in Kazakhstan, Siberia, and Transcaucasia, beetles of 2 species are predominantly found: eastern Khrushchev and western Khrushchev.

Western beetle spread throughout Eastern and Western Europe. What does the May bug beetle look like? Black, acorn-like body up to 32 mm long, with brick-brown elytra. The larva is white in color, arched, cylindrical, with brown jaws. The last portion of the abdomen on the underside is studded with conical setae arranged in 2 rows. The size of the larva reaches 65 mm.

Larvae and beetles winter in the soil at a depth of 25 to 150 cm. Adult insects, after the color of apple trees falls, lay eggs in heaps to a depth of 40 cm in heaps. Egg laying is located near the places where they feed. After about 30 days, larvae emerge from the eggs, which live in the soil for 3 years. Pupation takes place in June-July. The transformation of the pupa into an adult occurs in 30-40 days.

During the wintering period, beetles are greatly depleted. Therefore, in the spring they need enhanced nutrition. Years of beetles begins at dusk, immediately after sunset. Adult beetles eat leaves of trees, thereby weakening and inhibiting plantings.

May beetle larvae are initially inactive. The main food is soil with plant debris and small roots. With the onset of cold weather, they sink deeper into the ground.

At the end of summer molting at a second age, the larvae begin to eat the roots and trunks of plants.

Larvae of the second and third age do the most damage. Especially voracious on the eve of pupation.

Larvae gnaw roots not only in young seedlings, but also in fruit-bearing trees. The productivity, cold resistance of gardens is reduced.

May beetle is common in Western Europe, Siberia, Kazakhstan, Transbaikalia.

May bug looks the same as western bug. The difference is that it has a black antennae and legs, as well as a chitinous protrusion on the final segment of the abdomen. It leaves the soil 10-15 days earlier than the western one. It feeds day and night, sitting on trees. Inflicts damage on all species of deciduous and fruit species of trees, as well as on pine and larch.

Significance in nature and control measures

Chafer beetle is caught using traps, thrown from fruit trees and destroyed. Chemical disinfection of trees gives good results. Before planting, the seeds are hunted by larvae in the ground. During plowing and loosening of the soil, larvae and pupae are collected and destroyed. Use light traps of various designs.

May bug has natural enemies:

  1. A large motley woodpecker feeds its chicks with May bugs. He collects them from the surrounding trees and carries them into the hollow. With a powerful beak, he hammers a beetle into the slot and grinds the insect’s chitinous cover.
  2. Rooks and starlings catch bugs in the air, widely revealing their beak. Birds are very effective in fighting May bugs. To attract birds to the site, corn is planted.
  3. Pigs kept in enclosures eat May bugs and their larvae.
  4. Cats and dogs enjoy eating bugs with pleasure.

Due to the fact that the May beetles eat plant food, they are classified as phytophages.

Phytophages are important in the ecosystem — they are the second, after plants, link in the food chain.

Maintaining soil fertility at a stable level, they serve as food for their natural enemies.

How to get rid of the May bug

In the natural ecosystem, their numbers are constrained in a natural way — due to predators, the availability of nutrition. Never reaches a menacing level. Beetles are a danger to an artificially created ecosystem: gardens, vegetable gardens, potatoes. The larvae that form in the soil for three years cause damage to garden, vegetable and tree crops, to the berry. Planting of strawberries, garden flowers — roses, gladioli is damaged.

Means of struggle with the May beetle and its larvae

The beginning of the spring-summer season is always a joyful, but at the same time, troublesome event for every summer resident.

The onset of heat indicates the appearance of insects, some of which are useful for cultivated plants, while others only harm by devouring everything in its path.

One such pest is Chaferwhich adds a lot of trouble to any gardener.

Cockchafer is an insect rather large size reddish or black. Beetles breed at the end of spring, their larvae (crunches) mature for several years under the ground. Their jaws are already so strong that they are able to gnaw even old and powerful tree roots.

With the onset of heat from the pupa appears adult cockchaferThis happens in late August or early September. Adult hatching animals hibernate in the ground, and then again begin to resume offspring.

What harm does an insect do?

Main food May beetle are young shoots and leaves of the plant. The beetle is able to leave bare branches from a tree for a couple of months.

The beetle itself is not so scary for cultivated plants, most dangerous his larvae. They are almost invisible to the eye, because they are underground.

At the same time they destroy the root system of the plant, and it completely dies.

More often objects to attack beetle Trees such as cherry, apple, plum or sea buckthorn serve. The beetle also settles on currants and lilacs, birch and aspen. The larvae are not so selective in food and are able to destroy any plants that are only at the dacha.

  • Mode of application. Saplings plants dip their roots in the prepared solution. After 25 days, the roots are re-processed by the drug per 50 grams per 10 square meters, then planted in the soil.

Popular methods of dealing with the beetle

Effective will be the fight with Khrushchev folk remedies. The old way of catching beetle is shaking them off the trees. The procedure should be carried out in the morning or evening hours. Fallen from a tree individuals collected to females could not postpone laying, and destroy.

You can use to get rid of the beetle birds. Just set them on a certain plant with the help of cereals or any other food, you can also hang nesting boxes or start chickens.

Dig a hole, put a basin in it, the edges of which will be smeared with something sticky. Beetles are stuck and can not get out.

Hang a white sheet on a rope and highlight it. bright light. Such a trap will attract males of the May beetle, they will begin to crawl below the sheets and stir in the grass. It remains only to collect them in a separate container and destroy. On females This trap does not work.

Traditional recipes against the larvae of Khrushchev

How to kill the Maybot larva? The most popular, but time-consuming way to get rid of the larvae of the May beetle is their mechanical gathering. In spring, when the earth begins to warm enough, the larvae rise higher in heat and moisture. You can find them at a depth of 10-20 cm. All the larvae can not be collected, and digging the ground — not such a useful process for farming.

To combat the grubs of the Maybug with folk remedies, sow the spot lupine. Next to the lupine weeds do not grow, which means the larvae will have nothing to eat, so they will die.

Sow the area under the plant white clover. Nitrogen, which will be synthesized by bacteria found in the roots of clover, will make the soil uninhabitable for the larvae, but fertile for plant growth.

You can save currants and strawberries by spraying onion peel solution. 100 grams of husk insist in 10 liters of water for 5 days. The tincture is diluted in proportions of 1: 1 and sprayed on the affected plants and the ground beneath them.

Prevention of the appearance of beetles on the site

Nothing will protect better from a pest than timely prevention.

In the case of spring digging, you can add a little to it. bleach or a chlorine-containing drug, it will scare away the beetles.

You can save the strawberries with a solution liquid ammonia (half tbsp per 10 liters of water).

May beetle — a dangerous pest for any plant.

Should start the fight immediately with him, otherwise his larvae in a few moments will destroy all the works.

When processing from beetle larvae more efficient the total will help chemicals in conjunction with traditional methods.
