Pests cause a lot of trouble for gardeners. To preserve a fruitful berry, you need to know how to deal with harmful insects. Raspberry beetle, weevil, bug, raspberry fly, spider mite can harm berry bushes. We will present a description of insects, methods of control, what to do if the raspberry is wormy.

Description of the raspberry beetle

The pest insect that harms the berry bushes is called the raspberry beetle. In its natural environment, the raspberry beetle can settle on the bushes of forest raspberries, but it is just as dangerous for high-quality raspberries at their summer cottage.

A small bug can leave gardeners without raspberries. It is necessary to fight the pest using complex measures.

It is very difficult to notice the appearance of a raspberry beetle at the initial stage, a small insect is well camouflaged. Settling on raspberry leaves, the beetle begins to lay eggs on flowers and ovaries. The size of an adult insect is 4 mm. The beetle is light brown or yellow in color, the body is covered with fine hairs.

Raspberry beetle

After mating, the raspberry beetle lays eggs, from which larvae soon emerge. In appearance, they resemble a white worm. They grow in length up to 7 mm, the skin is covered with hairs. The larvae eat ripe raspberries, thereby spoiling their taste characteristics and marketable appearance. If the raspberries are shriveled and begin to deteriorate, then the bushes are affected by the raspberry beetle.

With the onset of spring, the bugs are activated. When the soil warms up to 12 degrees, they crawl out of the ground and get close to the raspberry bushes. As the foliage grows, the raspberry beetle eats the young leaves. Beetles move on the ground and in the air, they fly freely from bush to bush. If raspberries do not grow nearby, then they move to garden trees.

On a note. The female lays eggs in a flower. A week later, the caterpillar hatches, begins to eat raspberries. The female can lay up to 40 eggs.

The flower in which the larva develops begins to wither and deform. In 1.5 months, caterpillars can completely damage the crop. After they descend and burrow into the ground to a depth of 20 cm. Having buried in the ground, the larvae hibernate, the next year they pupate and again crawl out to the surface already in the form of a bug.

Control methods

An integrated approach is used to combat the raspberry beetle. Beetles are dangerous because they can completely destroy the crop, and in the new season they will again infect plants.

Biological and chemical methods of prevention against insect pests are used. If you use only chemicals, then this may be an ineffective way - the berry will be poisoned with chemicals.

To save the crop, the first thing to do is to prevent insect breeding. Raspberry fly, fighting it:

  • Before flowering, raspberry bushes are covered with gauze net. This will reduce the beetle's contact with flowers;
  • If a raspberry beetle was found while picking berries, then the crop is washed in slightly salty water. The larvae will crawl out of the pulp and can be collected;
  • Cover the holes around the bushes with non-woven material. Mulch will prevent the larvae from penetrating the ground for the winter. Agrospan, spunbond are used for mulching;
  • Beetles are afraid of ash and manure. Regular feeding and dusting the soil with ash will help scare off the pest;
  • Thinning bushes is a measure of insect prevention;
  • The beetles feed on raspberry leaves.The bushes are treated with Bordeaux liquid, this prevents fungal diseases, impairs the taste of the leaves;
  • Beetles do not tolerate acidic soil, so the soil can be acidified with coniferous sawdust;
  • In the spring, the soil around the bush is dug up, filling up the beetle's burrows. It is necessary to dig carefully, there is a risk of damaging the roots;
  • The bushes are recommended to be regularly examined for pests. If a beetle is found, it must be shaken off into a bucket or on a newspaper and destroyed. In the morning and evening hours, the raspberry beetle is lethargic, easier to collect;
  • Till the soil in autumn. The earth is powdered with tobacco dust. Weeds in the area where raspberries grow must be removed by the roots.

Preparations against the raspberry beetle

To combat the raspberry beetle, chemical and biological preparations are used.

On a note. The use of chemicals is allowed before the beginning of the flowering period and after the full harvest. The use of biological products is permitted at any time (spring, summer, autumn).

Insecticides against the raspberry beetle:

  • Kinmix (2.5 ml per 5 liters of water);
  • Karbofos (5 ml per 5 liters of water);
  • Alatar (2 ml for 5 liters of water);
  • Spark (1 tablet in 5 liters of water).

Biological preparations and folk methods:

  • Bitobaxicillin - broad-spectrum insectofugicide. The drug reduces the number of beetles;
  • Fitoverm (10 ml per 1 liter of water). The biological agent is allowed to be used during the fruiting period (June, July). The active substance of the drug does not affect the berries;
  • Bushes are treated with a weak solution of potassium permanganate in early spring;
  • Spray the bushes with tansy infusion. The grass makes the leaves bitter, the smell repels insects;
  • Insist 300 g of tobacco in 5 liters of water for a day. Boil the solution, cool, strain. Dilute with water, add grated laundry soap, water the bushes with the resulting solution;
  • The infusion of mustard powder repels the raspberry beetle. It is better to water raspberries in the morning or in the evening after sunset;
  • Baking soda solution (10 g per 5 liters of water). Irrigation with baking soda will scare away the pest and improve the presentation of the berry.

Complex methods of dealing with the raspberry beetle will allow gardeners to save the berry.
