Holes appeared on the raspberry leaves, what to do. Raspberry pests and methods of dealing with them

Getting a large harvest of raspberries is impossible without taking measures to protect plantings. Raspberry pests and the fight against them begins from the first days of spring and ends before the autumn snowfalls. To defeat the army of pests, you need to know their appearance and lifestyle well.

Raspberry pests

Wormy berries and dried shoots do not cause delight among gardeners. Hard work in the pursuit of a generous harvest can be reduced to zero by a small mosquito or midge. To prevent this from happening, you need to know how insects can damage raspberry plantations. Raspberry pests and methods of dealing with them are diverse, they must be recognized and applied correctly.

Raspberry gall midge or raspberry mosquito

A small brownish insect with transparent wings and 2 mm long. Produces three generations in one season.

Instead of infusion of tansy use:

  • sagebrush;
  • garlic arrows;
  • bitter capsicum;
  • potassium permanganate solution.

Infusion of garlic repels aphids and flower beetles: 500 g of garlic is crushed through a meat grinder and poured with three liters of water. Insist five days, filtered. Dilute in ten liters of 60 grams of infusion, adding a little liquid soap.

Summer processing

When raspberries bloom, any plantation treatments are excluded due to the possibility of harming pollinating insects.

Spraying bushes with insecticides:

  • Karbofos;
  • Cidalom;
  • Metaphos;
  • colloidal sulfur;
  • spark;
  • Fufanon;
  • Confidor.

Akreksom carried out after harvest. It is done up to 4 times a season with an interval of 10 days.

It is impossible to treat stems affected by pests from the inside. They need to be cut and burned.

Ammonia solution, infusion of tomato leaves, potatoes, wormwood, tansy repels aphids. Ammonia solution is sprayed on all sides of the leaves.

Sprinkling of the plantation in cloudy and evening weather prevents the spread of spider mites.

autumn processing

Two-year-old fruiting shoots and stems with cracks and scuffs of the bark, weak, diseased, unripe and extra branches are cut off.

If galls are located on the stems, then they cannot be treated. They are cut below the swelling. Drying, blackened stems are cut at the root.

Dig aisles, remove fallen leaves.

Prevention measures

The methods of how to deal with pests involve systematic care of the plantation and its treatment with the strongest chemicals. Such a fight against insects can affect consumers of berries from the wrong side. Therefore, work must begin with preventive measures.

Prevention from the appearance and reproduction of numerous pests will be a full care of the plantation. Measures aimed at increasing yields prevent the appearance of many pests. It's not hard to do, but it's quite effective:

  • prune biennial branches;
  • thin out plantings;
  • cut branches to burn;
  • all affected by swelling, cobwebs, drying branches should be removed immediately;
  • remove fallen leaves;
  • shallow loosen the soil;
  • remove weeds;
  • lay a layer of mulch at least 8 cm.

Using the recipe for a miraculous mixture invented by the outstanding gardener A.P. Bessarab, you can feed the plants, get rid of many pests. In the spring it is necessary to water the plantings, in the summer - spray on the foliage. Application - once a week.

Prepare the mixture:

  • 1 liter of whey;
  • 1 st. l. sour cream;
  • 1 st. l. honey;
  • 10 g of yeast;
  • 1 liter of warm water.

Dissolve the mixture in 10 liters of water and store in a dark place for a week until everything ferments. The principle of operation of the mixture is not in chemical elements, but in the vital activity of microbes that helped plants absorb nutrients and fight pests.

The symbiosis of microorganisms with raspberries is practiced in his nursery by another outstanding gardener A. Kuznetsov. His natural farming biotechnology involves the use of organic mulch with mycelium sprouting in it.

As a result, soil nutrition makes it possible to grow not with an excellent yield of berries. Moreover, instead of 4-5 shoots per square. m. he grows 30-40 shoots.

Conclusion

Raspberry pest control begins with caring for raspberries, cultivating the land, regulating the number of shoots, and mulching the soil. All these necessary measures not only strengthen the plants, but also prevent the appearance of numerous pests.

Mostly weakened plants, neglected and overgrown, are ill. Well-maintained plantations with strong plants are almost free from diseases and pests. It is worth remembering this.

Tender and tasty raspberries can give a good harvest, only if the rules of care and pest control are followed. Knowing the rules for processing raspberry buds, flowers, berries and leaves, the farmer will be able to get a tasty and natural crop that is not damaged by beetles, weevils, glass, fly, aphids and complex diseases.

Pests

Damages buds, flowers, berries and leaves of raspberries, as well as blackberries.

The beetle is 3.8-4.3 mm long, oblong, grayish-black, covered with dense rusty-yellow hairs. Larva yellowish, with sparse light hairs. On the ninth segment of its abdomen there are two spikes bent upwards.

The beetle develops in one generation per year. Beetles and larvae that have completed their development overwinter in the soil under raspberry bushes. In spring, the beetles leave their wintering grounds and feed on the flowers of various plants. Then the beetles move on to raspberries, where they gnaw holes in the leaves, eat buds and flowers. Females lay eggs one at a time in raspberry flowers and on the ovary. Egg laying continues until mid-summer. The egg stage lasts 10 days. The larvae eat the fruit and base of the berries. Damaged berries develop ugly, small, wither or rot. Having finished feeding, the larvae fall to the soil and pupate in it at a depth of 5-15 cm. Hatching beetles remain in the soil for the winter. Some of the larvae that have not completed their development are removed from the plot with berries during harvesting.

The larvae that overwintered in the soil do not pupate in the spring, but remain dormant in it until August, after which they pupate and give rise to beetles.

Control measures. Shaking (repeatedly) beetles from plants onto bedding or netting and destroying them.

Digging the soil in autumn. Collection of berries in a dense container with a selection and destruction of the larvae accumulating at the bottom. Spraying plants during budding with karbofos against beetles.

Damages raspberries and strawberries, causing the buds to dry out.

The beetle is black, in dense light gray hairs, 2.5-3 mm long, with a thin, long, slightly curved proboscis. The adult larva is up to 3.5 mm long, grayish-white, legless (Fig. 10).

Beetles hibernate on the soil surface under plant debris or under clods of earth. In the spring, with the beginning of the growth of strawberries, the beetles leave their wintering places. First, they feed on leaves and petioles, then they gnaw through the buds with their proboscis and eat out the anthers. When the strawberries bloom, the females start laying eggs, place them one at a time in well-developed buds. With the appearance of buds on raspberries, the beetles move on to it and continue laying eggs. After laying each egg, the female gnaws the pedicel of the bud. The bud breaks and falls off or withers, remaining hanging on the skin of the stalk. The larvae feed on the contents of the damaged bud. The duration of the development of the larva is 20-25 days. Their pupation occurs during the mass ripening of berries.

Young beetles feed until autumn, eating small holes in the leaves and deep pits in the petioles.

Control measures. Spraying strawberries and raspberries before flowering against overwintered beetles. In August, after harvesting, spraying can be repeated against the new generation of beetles. Shaking beetles off plants onto bedding and destroying them. Collection and destruction of fallen buds with larvae.

Damages raspberries. The caterpillars feed on the core of the stems.

The butterfly is bluish-black, with transparent wings, the span of which is 22-26 mm. There are transverse yellow rings on the abdomen: females have three, males have four.

Caterpillars hibernate inside raspberry stems in their basal part. In the spring they continue to feed. This is where the caterpillars pupate. Butterflies fly in June-July. The females lay their eggs on the soil near the raspberry stalks. The caterpillar penetrates the stem and root, where it makes a move. Damaged stems bear fruit poorly, dry out, break.

Control measures. Cutting and burning the shoots damaged by caterpillars. Digging the soil around the bushes in June-July, when pupae are in it.

Damages raspberries. The larvae live inside the young stems, causing them to wilt.

The length of the fly is 5-7 mm, it is gray in color. The larva is whitish, cylindrical, legless.

The larvae overwinter in a false cocoon in the soil at a depth of 5-6 cm. In the spring, with the growth of raspberry shoots, flies fly out. Females lay one egg at a time on the tops of the shoots. The hatched larvae penetrate the stem and eat out a spiral course in it to the base of the shoot. Damaged shoots wither and rot. During the flowering of raspberries, the larvae complete their development, go into the soil, form a false cocoon and remain in it for the winter.

Control measures. Systematic cutting of withering shoots to the undamaged part and burning them. Loosening the soil under the bushes in spring or autumn. Spraying raspberries during their budding with karbofos against adult flies.

Damages raspberries. In places where larvae feed, galls form on the lower part of the stem.

The mosquito is 1.6-2.2 mm long, black, its back is covered with light yellow hairs. Larvae are small, legless, orange-yellow.

One-year generation. The larvae hibernate inside the galls on the lower part of the stems. Up to ten larvae hibernate in one gall. In the spring, feeding of the larvae continues. Mosquitoes fly during raspberry blossom. Females lay eggs in groups of 8-15 on young raspberry shoots. After hatching, the larvae penetrate under the bark of the shoot, feeding on its juice. In the feeding place of the larvae, a gall is formed up to 3 cm in length and up to 2 cm in width. Inside the gall, the larvae remain overwintering.

Control measures. Cut below the gall and burn damaged shoots in autumn or early spring.

shoot aphid

Damages raspberries. Aphids are light green, up to 2.5 mm long.

Shiny black eggs overwinter on shoots. The larvae hatch from the eggs during the budding. They suck juice. By the time the buds are exposed, aphids colonize the tops of the shoots, petioles, and leaves in large colonies. Damaged shoots are bent, their growth stops, the leaves are twisted. Such shoots do not bear fruit, the flowers dry up on them. During the growing season, aphids develop in several generations.

Control measures. Cutting and burning the tops of damaged shoots along with aphids. Spraying the bushes before flowering and after harvesting with karbofos or green soap.

Diseases

It affects shoots, petioles, leaves and fruits of raspberries. The fungus overwinters on leaves and stems and is spread by spores. On shoots, petioles and leaf veins, the disease appears as oval or rounded spots with a wide purple border around the edges. When the spots merge, the bark cracks along, forming ulcers. Severely affected stems dry out. Diseased leaves stop growing, curl up and dry out, the berries turn gray and also dry out. Wet weather favors the development of the disease. The maximum development of the disease occurs in July and August.

Control measures. Removal and destruction of affected stems and leaves after harvest. Loosening the soil in autumn or early spring with careful incorporation of fallen leaves and other plant debris. Cutting and destruction from fruiting shoots. Thinning dense plantings to improve ventilation. Spraying bushes in the spring before bud break with copper sulfate, and before flowering and after it with Bordeaux mixture of 1% concentration.

The fungus infects the shoots and leaves of raspberries. The mushroom overwinters on fallen leaves in the form of a cluster of spores. In spring, spores disperse and infect plants. Yellow pads of summer spores appear on the upper side of the green leaves. By autumn, these pads turn black, and the spores formed on them hibernate. Affected leaves dry out prematurely and fall off, young shoots are stunted in growth: they gradually die off.

Control measures. The same as with anthracnose.

White spot (septoria) raspberries

It affects the stems and leaves of raspberries. The fungus overwinters on them. The first signs of the disease appear at the end of May. Whitish spots appear on the leaves with a narrow brown border up to 3 mm in diameter. On the stems, the spots are small, vague, inconspicuous. The diseased tissue of the stems cracks. On the damaged tissue of stems and leaves, black dots of sporulation develop in summer.

In addition to white spotting, raspberries can suffer from brown and purple spots. Brown spotting appears on the leaves in the form of red-brown spots of a rounded or angular shape. Purple spotting is distinguished by the purple color of the spots on the shoots and leaves. Merging, the spots encircle the shoot, the skin on the spots cracks, peels off. Both fungi overwinter on affected leaves and stems.

Measures to combat spotting are the same as with anthracnose.

And we them! In a folk way! Destruction of raspberry pests by folk methods

WE PROTECT RASPBERRY FROM PESTS WITHOUT CHEMISTRY

Raspberry beetle and other pests.

RASPBERRY BEETLE

The most common pest is the raspberry beetle. The beetle is small (4 mm), grayish in color. The larva is grayish-yellow, up to 7 mm long. Young beetles and larvae overwinter in the soil at a depth of 5-10 cm. In mid-May, the beetles emerge from the ground and feed on the stamens and pistils of flowers of fruit trees, early flowering shrubs and weeds (dandelion, deaf nettle, etc.).
Then they move to raspberry buds and eat out the inside, gnaw at young leaves. Then the larvae begin to feed, born from eggs, which the females laid before flowering on the underside of young leaves, in flowers and on young ovaries. They penetrate into the seed and bite into the receptacle, causing the worminess of the berries. In early August, the larvae go into the soil.

Ways to fight. Before flowering raspberries in the morning, shake the beetles from the plants onto a film or into an open umbrella and destroy them. To prevent pests from reaching the bushes, during the period when the buds appear, you can cover the raspberries with non-woven material, which should be removed when the flowers begin to open.

Spraying the bushes during the appearance of buds with infusion of tansy also helps. Take 300-400 g of dried shoots or 1-1.2 kg of fresh plants, pour 5 liters of water and leave for 1-2 days. Then boil for 25-30 minutes, filter and bring to 10 liters of cold water. Spraying is carried out in the evening on buds, abundantly, spending about 1 liter per 1 running meter of the row.

In autumn, they must dig up the soil around the bushes to a depth of 15-20 cm. Such digging destroys beetles and larvae that have prepared to winter in raspberries.

RASPBERRY STEM FLY

A small gray fly 5 mm long causes great damage to young raspberry shoots. The pupae of the fly hibernate in the upper soil layer under the bushes. In mid-May, when the shoots reach a length of 10-15 cm, the fly flies out and lays eggs on their tops, in the axils of the leaves. The shoots are crescent-shaped, droop, turn black and wither. At their base, a circular passage is visible, inside of which there is a wormhole and white larvae.
During the flowering of raspberries, pests go into the soil. And the young shoots damaged by them die off, as a result, the next year the number of fruit-bearing stems becomes smaller, and the crop accordingly decreases.

Ways to fight. In the spring, when the first signs of wilting appear, the damaged shoots are immediately cut out and burned. The soil under the bushes is loosened, thereby destroying the larvae that have gone there. Chemical control of stem fly is not recommended.

SPIDER MITE

In dry years, the spider mite can lead to a loss of 30-70% of the crop. Thickened plantings are most severely damaged.
In the spring, multiplying rapidly, in a short time the mite infects all the leaves in the raspberry. They curl, turn yellow and fall prematurely in July-August. Because of this, the frost resistance of the shoots decreases, and they freeze slightly. Females hibernate on fallen leaves.

Ways to fight. For prevention in the spring, before bud break, the bushes are sprayed with a 6-7% urea solution. With a very strong infection in the previous year, they are treated with fufanon (10 ml / 10 l of water) with a consumption of 2 l per 10 bushes.
After picking the berries, they are sprayed with actellik or akrex (15-20 g per 10 l of water), with a strong reproduction of the pest, the treatment is repeated.

Spraying with acrex gives the greatest effect, therefore, when it is used after picking berries the next year in early spring, treatment can be omitted.

RASPBERRY MITE

During the period of bud break, the raspberry mite populates the underside of the leaves. They change color, become covered with pale green oily spots, become wrinkled.
Often these signs are misleading that the bush is affected by a viral disease. The pest hibernates under the scales of raspberry buds.
- Methods of struggle. Same as with spider mites.

STEM raspberry gall midge

A tiny insect (up to 2 mm) is a stem raspberry gall midge, similar to a mosquito. The larva is orange-yellow, 3 mm long. Adult insects settle on raspberry stems during the flowering period.
Females lay their eggs in clusters at the base of the buds or at the bottom of young shoots. The hatching larvae feed on them. You can detect them by swellings (galls) in places of feeding. The bark of the damaged shoot bursts, he himself lags behind in development. The larvae overwinter in the galls.

Ways to fight. In autumn, after leaf fall or early spring, the shoots are carefully examined. The damaged ones are cut out along with the galls and burned.

SHEETS SHEETS OR RASPBERRY KOMARIK

The most dangerous and widespread pest of raspberries is the gall midge or raspberry mosquito. The larvae overwinter in the topsoil at the base of the stems. In the second half of May, females appear, which lay their eggs under the bark of young shoots, in places of mechanical damage or in the bases of the stems and petioles of the lower leaves.
Hatching orange larvae live in colonies of 150-200 pieces. The shoot damaged by them dries out either in winter (false freezing), or the next year during flowering or ripening of berries.

Varieties with cracking bark are especially affected. Sometimes all stems may be without berries. In spring, in a heavily damaged raspberry tree, you can see many shoots broken at a height of 10-15 cm from the soil surface.

Even with a slight damage by gall midge, raspberries weaken and become a victim of fungal diseases, which also causes the death of shoots.

Ways to fight. When creating raspberries, only absolutely healthy planting material is used, and for a greater guarantee, young plants are planted without an aerial part, that is, only rhizomes. On the affected bushes, damaged shoots are cut out and burned in the fall. There are no chemical means of control.

RASPBERRY STRAWBERRY WELVIL OR FLOWER

The raspberry-strawberry weevil or flower beetle causes great harm to raspberry plants, sometimes destroying 50-80% of the buds. The beetle is grayish-black, 2-3 mm long, with a long proboscis. The larva is white with a yellow head. First, the beetle gnaws out strawberry buds, then moves on to raspberries.

Females lay their eggs in a bud and gnaw its leg. The bud withers and falls, the larvae calmly pupate in it. Young beetles emerge from pupae in August, feed on raspberry and strawberry leaves, and in autumn they go to winter in the soil, under dry leaves, plant debris.

Ways to fight. When the buds appear, without waiting for them to open, a deterrent spraying is carried out with an infusion of garlic. It is prepared as follows: 500 g of cloves are passed through a meat grinder, placed in a 3-liter jar, poured with water at room temperature and infused in a dark place for 5 days. Then filter and dilute: 60 ml of infusion per 10 liters of water. Add 50 g of planed laundry soap and spray the bushes. Processing is carried out 2-3 times a day.

In autumn, all plant residues are removed from the raspberries and burned. The soil around the bushes and between the rows is loosened, thereby destroying the pests that have prepared for wintering.

One of the pests that attack raspberries is called the raspberry beetle (Byturus tomentosus). Attacks raspberries in the European part, the Caucasus, Western Siberia. Makes berries unsuitable for sale, consumption.

raspberry pest

This is a beetle with a slightly oblong oval body 4-4.3 mm long. It is completely covered with gray and yellow hairs. Order Coleoptera (raspberry family). The laying of eggs is located in a flower or a young juicy ovary. The characteristic elytra is gray with a black tint. Description in the immature phase of the larva: looks like a caterpillar up to 7 mm long. There are bristles on the back.

Harm is brought by both adults and larvae. The pest develops in one generation. The raspberry beetle appears on raspberries in spring at a soil temperature of +12 degrees. It crawls out of it, moves to a bush, where it feasts on foliage, flowers of weeds that have not yet blossomed and blossomed. Able to fly, the beetles migrate from bush to bush. They spoil the stone fruit, cloudberry, blackberry, bird cherry, apple tree, pear.

The female beetle lays an egg in a flower, being able to lay up to 40 eggs during the growing season. After 7-10 days, larvae appear with characteristic spikes raised upwards. Caterpillars harm the inflorescences, making moves in their pulp and damaging the receptacle. It is quite difficult to detect in fruits. As a result, deformed, underdeveloped fruits are formed. Over time, they fade, crumble. The larvae also feed on ripe fruits. This continues for 40-45 days, after which some of them fall to the ground, fall into a passive life cycle, to pupate only a year later, in August. Others hibernate in roots, in moist, loose soil, at a depth of 0.15-0.20 m. Young adults form from such caterpillars in early August of the current year.

Attention! According to statistics, the beetle and its larvae, damaging the berries, can destroy up to half of the entire expected crop.

How to fight?

In order to limit the spread of the pest on plantations, it is recommended to carry out preventive measures:

  • Fertilizing plants with organic fertilizers, ash.
  • Organized watering.
  • Thinning raspberry thickets, ensuring sufficient air circulation.
  • For the purpose of prevention, early spring treatment with Bordeaux mixture (2%) is practiced.
  • In the last days of autumn, after the destruction of the remaining weeds, the soil in the root zone is dug up, at the same time beetles, larvae and pupae that have gathered to winter are destroyed. Before loosening the earth, it is sprinkled with tobacco dust.
  • Mulching with sponbond “SUF-ks-60. Anti-weed "or flax.
  • You can make a slight acidification of the soil. To do this, treat a layer (3-5 cm) of coniferous sawdust under a bush with humate.
  • In early spring, until the beetle has flown out, dig the soil shallowly without damaging the root and shovel the beetle burrows.
  • Because after departure, the beetle feeds on flowering crops; raspberry cuttings should not be planted under pears and apple trees.
  • If insects that have occupied them are found on the bushes that are about to bloom, pests should be shaken on a lined film, newspaper. Then burn or place in a water-kerosene emulsion. The collection of beetles is carried out in the morning, while they are not active.
  • At the end of summer, when pupation begins, cultivate the soil top layer under the shrub.
  • Carry out a constant inspection of the bushes and manual collection of damaged, withered, dried berries. They need to be burned.
  • When harvesting, ripe berries are placed in closed containers, boxes. The larvae crawling out and remaining in a confined space are collected and destroyed.

Attention! Some gardeners, before fighting the raspberry beetle, stock up on agrofibre, gauze, and nylon. During the period of bud formation and the appearance of the first flowers, the raspberry bush is covered with a cellular cloth, blocking the access of the flying pest to the inflorescences. Only after the blooming of almost half of the buds, the fabric is removed.

Insecticide attacks

Chemical methods of struggle are repeated twice. Otherwise, you should not count on effective plant protection. Popular drugs:

  • If the population of beetles is large, at the beginning of the appearance of only formed buds, sprinkle raspberries (90g per bucket of water).
  • 2.5 ml solution diluted in 10 liters of water. Spraying, taking into account the consumption of 1.5 liters per 10 bushes.
  • With severe damage, you can use methods of dealing with such drugs: Fufanon solution (0.1%) in the bud formation phase, "Spark" (1 tablet dissolved in 10 liters of water) before and after flowering. Fufanon is a stable drug. Its damaging effect persists for 21-25 days from the date of treatment.

You can supplement the list of chemicals with Phosbecid, Inta-Vir,. Preparation of chemicals is carried out according to the attached instructions. It is economically beneficial to use insecticides if 3-4 caterpillars or beetles were found on one bush during the examination of the raspberry bush.

"Cure" from the people

Folk methods of struggle are based on the results of many years of observation. So, experienced gardeners do not recommend immediately throwing away damaged raspberry fruits. First, they are poured with lightly salted water. After 0.5 hours, the pest will crawl out. Berries - for processing, larvae - for birds.

By the way! Birds (hoverflies, ground beetles) - the natural enemies of the raspberry beetle - can be attracted to the garden if garlic or onions are planted near raspberry bushes. Hoverflies are insects that look like large wasps, do not bite, hang in the air for a long time. There are more than 40 species of ground beetles in nature. I attack inactive beetles at night, eating them.

Many drugs, as well as preventive measures, play a complex role, affecting other pests.

Raspberry pests cause great damage to the crop, oppressing plants, affecting health and stunting growth. Most infectious diseases are carried by pests such as aphids or mites. Raspberries have beneficial properties and are considered a valuable crop.

In order not to lose the crop and not expose the plants to such danger, it is better to carry out preventive measures to combat the garden pest, in particular raspberries. With a massive defeat of shrubs, there is often nothing to save, and gardeners have additional problems and difficulties.

Raspberry strawberry weevil

Raspberry-strawberry weevil is a small grayish-black bug 2-3 mm long. Adult beetles hibernate under fallen leaves and lumps of earth. This pest is common to strawberries and raspberries. Initially, the bug attacks garden strawberries. By the time the strawberries bloom, the weevil lays its eggs inside the buds, gnaws the pedicel, and the buds fall off.

The female weevil bug lays 50 eggs, one per bud. The larvae hatch from the eggs and feed on the buds until they pupate. Young bugs appear in June - July, eat young leaves and move together to raspberries.

In this regard, it is not recommended to plant strawberries next to raspberries. Although in the cramped conditions of a small area of ​​​​this neighborhood it is difficult to avoid. The main role in the destruction of the weevil is played by the correct agricultural technology, that is, the collection and destruction of old leaves and treatment with insecticides.

Weevil fight

Collection and destruction of plant residues, dead leaves. Spraying. If strawberries grow on the site, then spraying should be carried out during the formation of buds, a week before flowering. Raspberries are sprayed on the buds a week before flowering. The second time spraying is carried out after harvesting.

raspberry beetle

The raspberry beetle, as a result of its activity, damages the fruits and leaves of raspberries. Raspberry beetle larvae damage the berries, which become ugly and rot.

Usually beetles appear in the first half of May. They lay their eggs on the underside of the leaf, and then in the flowers and on the young tops. Each female lays 40 eggs. Having hatched from eggs, the larvae penetrate the fruits.

By the time of harvest, the larvae hide in the soil, where some of them again turn into beetles, while others remain to winter in the form of pupae. Both pupae and beetles hibernate in the soil under raspberries.

Measures to combat the raspberry beetle.

Spraying with insecticide preparations is carried out at the following times:

First spraying: during the budding period, no later than a week before the start of raspberry flowering. The same spraying will also destroy the weevil beetles that attack raspberries.

Second spraying: it is carried out with the mass appearance of larvae. The term of the second spraying is 15 days after the start of flowering.

They dig and loosen the soil around the bushes and in the aisles. In small raspberries in cloudy weather, beetles are collected by shaking in containers with subsequent destruction.

raspberry moth

The raspberry moth, or raspberry budworm, is another dangerous pest. Moth caterpillars attack swollen raspberry buds in the spring, after emerging from cocoons. Cocoons hibernate under loose bark, under plant debris, in old stumps. Damaged buds do not bloom and die. Caterpillars are easy to recognize by their appearance: they have a bright red color and a black head. Track length 9 mm.

Measures to combat raspberry moth

Carefully cut off the fruiting shoots, leaving no stumps. Penki is a wintering place for cocoons with wintering moth caterpillars. Spraying is carried out in early spring, before bud break.

raspberry gall midge

Gall midges are small mosquitoes. Sometimes galls are found on the surface of raspberries. If such galls are opened, then inside there are small orange-yellow legless larvae. After wintering, the pupae turn into small mosquitoes up to 2 mm in May.

Control measures for gall midge

Inspection of raspberry shoots and burning of infected shoots.

raspberry aphid

Aphids are sucking insects that feed on plant sap. This type of aphid inhabits young shoots, leaves and flower clusters of raspberries. The aphids suck out the juices, thereby causing the leaves to curl. Shoots become underdeveloped, fruiting slows down. In addition, aphids are a carrier of many viral diseases of raspberries. The fight against aphids should be given special attention.

Measures to combat raspberry aphids

Early spring spraying before bud break or at the beginning of bud break along the green cone. At this time, the larvae openly feed on the surface of the kidneys. During the summer, when aphids appear, re-spray with insecticide preparations. From folk methods, aphids can be fought by spraying with soapy water. For 10 l. water take 250-300 gr. soap. Soap must first be cut and dissolved in hot water. You can take 40 gr. liquid soap for 10 liters of water. Also, aphids are fought with infusion of shag or tobacco dust.

spider mite

The spider mite is polyphagous. It affects many plants, including currants and gooseberries. Female ticks hibernate under plant debris, lumps of earth, in crevices. On the underside of the leaf, the females lay round transparent eggs, from which the larvae emerge. Often, the initial development takes place on weeds, from where the larvae move to cultivated plants.

Currants, strawberries, raspberries suffer. The tick develops rapidly, the number of generations per season can reach 10. The mass development of the tick occurs at the end of July-beginning of August. The female mites are yellow-green in color. In September, ticks leave for the winter. By the end of summer, the color of the mites becomes orange-red, which is clearly visible. Leaves infected with spider mites turn yellow, dry out, and discolor.

Measures to combat paut other tick

Collection and destruction of plant residues, fallen leaves. Digging the soil. These activities hinder wintering and cause the death of the bulk of ticks. Spraying with insecticides. Spraying time: the period of bud break. At this time, the females come out of wintering and begin to crawl onto the bushes.

In case of severe infection, re-spraying is carried out before flowering. Yellow-orange females are clearly visible on the leaves. In the future, monitor the situation and, with an increase in the number of ticks, carry out processing.

How to identify raspberry pests by damage

Kidney damage by pests.

Raspberry moth: The buds do not open or dry up. Small holes, cobwebs are visible on dying kidneys. Inside the kidneys, you can find small red caterpillars with a black head.

Damage to buds and flowers by raspberry pests

Raspberry-strawberry weevil: The buds do not open, droop and hang gnawed. In the future, they turn brown, dry up and fall off. Inside the bud is a small legless larva with a brown head.

Raspberry beetle: The inner part of the buds (stamens and pistils) are eaten away, but the pedicels are not damaged. Buds are eaten by small grayish-golden beetles up to 4.5 mm long.

Damage to berries by raspberry pests

Raspberry beetle: A yellowish larva up to 7 mm long lives inside the berry. Berries change shape and rot.

Leaf damage

Raspberry aphid: The leaves at the ends of the shoots curl into a ball. The shoots are bent. On the underside of the leaves are colonies of small insects.

Spider mite: Small whitish spots appear on the leaves. Leaves discolor, warp, turn yellow, fall off. The underside of the leaf is braided with a thin cobweb, among which there are small grayish pests. The spider mite has a very wide distribution.

Caterpillars of various butterflies: There are holes of various shapes on the leaves, often from the edges.

Damage to the stems of raspberry pests

Raspberry gall midge: Galls and swellings form on the shoots. Sometimes the galls reach a length of 8 cm. The galls are covered with a rough bark. Inside the gall are small legless larvae.

Raspberry moth: The upper parts of young shoots are damaged. Inside the shoot is a passage in which there is a small red caterpillar with a black head.

General terms for spraying raspberries with insecticides:

  • First: Eradication spraying in early spring on dormant buds and soil around the bushes
  • Second: During the budding period a week before flowering
  • Third: After the harvest
