Along with other pests, sawflies cause severe, sometimes irreparable damage to garden and vegetable crops. These insects damage fruit and berry bushes, fruit trees, some species settle in cereal crops, destroying agricultural land. Every gardener needs to know how to deal with sawfly in order to protect their harvest.
Cherry slimy sawfly: pest control measures
Cherry slimy sawfly is a shiny black hymenopteran insect, up to 6 mm long. The larvae are greenish-yellow and have a pronounced thickening in the anterior part. On top they are covered with black mucous secretions.
The larvae overwinter in the soil near a tree at a depth of 15 cm. Insects fly out in late May - early June. Females lay eggs in the leaf tissue, resulting in a brown tubercle appearing on the upper side. After two weeks, larvae form and feed on the pulp of the upper part of the leaf.
In case of mass pest invasions, only veins remain from the leaves. The trees appear to be scorched in appearance.
After a month, the larvae move to the soil for the winter. In dry years, they can remain there for several years without coming to the surface.
The main measures to combat cherry mucous sawfly are spraying trees with chamomile infusion. To prepare it, you need to mix 800 g of dried and thoroughly crushed herbs and 150 g of chamomile inflorescences. Pour 10 liters of mixture warm water, leave for 24 hours, strain, dilute with 15 liters of water, dissolve 15 g grated in the infusion laundry soap. Spraying should be carried out 3 times a week with a break. Treatment should be stopped 2 weeks before harvest.
Pear weaver sawfly: photos and control measures
The pear weaver sawfly is an insect with a black head and a reddish abdomen. The body length of the pear sawfly sometimes reaches 14 mm.
Look at the photo: the wings of the sawfly weaver are covered with dark stripes. The caterpillars are orange-yellow, up to 20 mm long, with two shoots at the end.
The pear weaver sawfly mainly damages pears, but is sometimes found on hawthorn and other fruit trees.
The larvae overwinter in the soil near a tree at a depth of 10 cm. Sawflies fly out in early June. Females lay up to 70 eggs on the underside of leaves. Then larvae emerge from them, which are first located in groups in common web nests, eating away the pulp of the leaf. Later, they are found alone in the leaves rolled up and wrapped in cobwebs, eating them.
When a pear sawfly invades, all the leaves of the tree can be destroyed. In autumn, insects move to the soil for the winter. In dry years, they can remain there for up to several years without coming to the surface.
To combat the weaver sawfly, it is necessary to collect and burn spider nests with its larvae.
Control of yellow gooseberry sawfly
Caterpillars of the yellow gooseberry sawfly cause significant damage to plants in a short time. They destroy red currant leaves and completely eat them. As a result, only thick veins remain, and the bushes can be completely devoid of leaves. In addition, the growth and development of fruits stops - the berries remain small, wither and fall off. The plants themselves, affected by the pest, do not tolerate winter well and may die.
You can see what the gooseberry sawfly looks like in the photo below:
During the period of sawfly pupation, it is necessary to carry out autumn digging of the soil and loosening.
To protect plants from pests, infusions and decoctions of insecticidal plants (garlic, wormwood, tobacco) are also used and sprayed with infusion of ash. In addition, control measures for gooseberry sawfly include manual collection insects, as well as shaking them from bushes onto newspapers or cloth.
For getting good harvest gooseberries should be created on the site from the very beginning favorable conditions for the development of plants so that they themselves can resist pests and...
It is also necessary to remember that it is much easier to introduce pests such as aphids or sawflies, as well as pathogens of various diseases, into the seedling area than to get rid of them. Therefore, before planting, it is necessary to carefully check the planting material.
Control measures for yellow plum sawfly
This insect is a yellow-brown hymenopteran insect with a body length of 5 mm.
As you can see in the photo, plum sawfly larvae are yellowish-brown, up to 9 mm long.
The larvae overwinter in the soil near a tree at a depth of 10 cm, where they then pupate.
Sawflies fly out about 5 days before the flowering of plums, cherries, sweet cherries, cherry plums, apricots and other stone fruits, which they infect.
Females lay eggs in buds and flowers. After a few weeks, larvae appear and feed on the pulp of the ovary. Interior damaged fruits are filled with watery excrement of larvae, which have a sharp unpleasant smell. Each plum sawfly caterpillar can damage up to 6 fruits.
After about a month, the feeding period of the larvae ends. They move to the soil for the winter. In dry years, the larvae can remain in the soil for several years without emerging to the surface.
One of the effective measures to combat the yellow plum sawfly is spraying with marigold infusion. To prepare it, you need to pour 15 cups of dry crushed marigold flowers into 8 liters of boiling water, add 20g of laundry soap previously grated on a coarse grater, mix, leave for 18-20 hours. Spraying with infusion should be carried out 2 times a week, preferably in the morning. Treatment should be stopped 10 days before harvest.
How to deal with slimy sawfly and photos of the pest
The slimy sawfly damages the leaves of stone fruits. Adults have a shiny black body, as well as two pairs of transparent wings, the span of which is 8-9 mm. Body length - 6 mm. The greatest danger is larvae.
Pay attention to the photo: The slimy sawfly has a greenish-yellow body (up to 10 mm long) with a thickening, the front part of which is covered with black mucus.
With the onset of spring, adult insects leave earthen cocoons and lay pale green eggs on the underside of leaves fruit trees. Having hatched, the larvae begin to damage the flesh of the upper side of the leaves.
In the process of dealing with the slimy sawfly, you must dig up the soil in the fall. This event helps to destroy the larvae that have entered it.
Fighting cherry sawfly
The cherry sawfly is a black insect with yellow and white stripes. The body length of the cherry sawfly is up to 10 mm.
Look at the photo: Sawfly larvae are up to 12 mm long, dark green, with a dark stripe on the back.
Cherry sawfly caterpillars damage the leaves of cherries, sweet cherries and other stone fruits.
The larvae overwinter in the soil near the tree at a depth of 25 cm. Insects fly out during the period when the cherry buds open. Females lay up to 70 eggs on the underside of leaves. By the beginning of June, larvae appear, which are first located in common spider nests, eating away the pulp of the leaf. Then they live alone in the leaves rolled up and wrapped in cobwebs, eating them.
In case of mass invasions of the cherry sawfly, all the leaves of the tree can be destroyed.
By August, the larvae move to the soil for the winter. In dry years, they can remain there for two years without coming to the surface.
To combat the cherry sawfly, the soil around cherry, cherry and apricot trees should be dug up. It is necessary to collect and burn spider nests with cherry sawfly larvae.
Apple fruit sawfly: photos and control measures
The apple fruit sawfly belongs to the order Hymenoptera; it reaches a length of 6-7 mm. The body color is yellow below, black above.
As you can see in the photo, the wings of the apple sawfly are transparent with a network of dark veins. The female lays one egg in the receptacle of a flower or bud, having first sawed through its skin with her abdomen. The larvae of the apple sawfly are caterpillars up to 10 mm long, pale yellow in color, and externally reminiscent of the caterpillars of the apple moth.
Apple sawfly caterpillars pose the greatest danger to gardeners, since the pest settles in the ovary of the plant immediately after flowering, after which it destroys the seed chamber. The resulting space (usually in the center of the fruit), the apple sawfly larva fills with its gelatinous secretions Brown having a characteristic odor.
The main measure to combat apple sawfly is to spray the trees with chamomile infusion. To prepare it, you need to mix 800 g of dried and thoroughly crushed herbs and 150 g of chamomile inflorescences.
Pour the mixture into 10 liters of warm water, leave for 24 hours, strain, dilute with 15 liters of water, dissolve 15 g of grated laundry soap in the infusion. Spraying should be carried out 3 times a week with a break. Treatment should be stopped 2 weeks before harvest.
Fighting the pale-legged gooseberry sawfly and photo of the pest
The false caterpillars of the gooseberry sawfly eat the leaves of gooseberries, red and white currants down to the veins. Adult larvae overwinter in dense cobweb cocoons. They burrow into the soil under bushes to a depth of 15 cm. In early spring their pupation occurs. After the leaves bloom, butterflies appear and lay eggs along the veins on the underside of the leaf. One female can lay up to 150 eggs.
Pay attention to the photo: The false caterpillars of the pale-legged gooseberry sawfly have ten pairs of legs. The larvae are green with a noticeable brown head.
During the summer, 2-3 generations of sawflies appear.
To combat the pale-legged gooseberry sawfly, it is recommended to dig up and loosen the soil under gooseberry and currant bushes, rake and remove fallen leaves in a timely manner.
You can shake sawfly caterpillars into a bucket and then destroy them.
In case of a massive pest invasion, it is recommended to spray with infusion of calendula and dandelion roots. To prepare it, you need to mix 400 g of calendula flowers and 150 g of dandelion roots. Pour the mixture into 10 liters of boiling water, leave for at least 2 hours, strain. Spraying with infusion should be carried out immediately after its preparation. The first spraying should be carried out from the moment the buds open until the buds separate, and the second - immediately after flowering. If new sawfly larvae appear after harvesting, you can carry out another spraying.
Linden slimy sawfly ( Caliroa annulipes. Family Tenthredinidae- real sawflies). The name of the pest is the linden slimy sawfly, but this does not mean that it only affects linden trees. Its voracious larvae, which simultaneously resemble both slugs and leeches, gnaw through the leaf plate, leaving behind an openwork skeleton. Usually young trees suffer from this pest; it rarely attacks strong adult specimens.
Found everywhere
In Russia, the linden mucous sawfly is found everywhere. The larvae feed on oak, birch, willow, beech and blueberry, gnawing out the tissue between the veins of the leaves, skeletonizing them. This pest lives on trees in thinned out stands, on southern, well-lit slopes. Prefers leaves of the upper tier of the crown and its southern part, outer branches, well-lit individual trees, and is not found in the center of the planting.
It causes the greatest harm in young forests, nurseries, parks, squares, shelterbelts, roadside strips and street plantings.
Older trees are rarely damaged, and predominantly individual well-lit branches are colonized.
Imago
Adult larvae do not descend along branches and trunks to the ground to cocoon, but always fall from the leaves. Imago (adult insects) fly in the first ten days of June. The male and female are small, 4 to 6 mm long, with two pairs of transparent wings. The body is black, shiny, antennae and legs are black. Females lay eggs scattered between the veins on the lower surface of the leaf blade, under the epidermis of the leaves, in cuts made with the help of the ovipositor in the parenchyma of the underside of the leaf - the so-called pockets. The masonry is clearly visible and looks like small brown swellings. Females lay 10–30 eggs on one leaf, and their fertility is 50–70 eggs.

Life for the larva
Embryonic development lasts 1–2 weeks. When hatching, the larvae gnaw exit holes in the dome of the egg sac through which they pass out. One leaf blade can contain from 2 to 28 eggs, more often 9–14.
The hatched larvae are soon covered with transparent yellowish mucus. They are small at first, but can reach a length of 12 mm. The duration of the larval stage is 15–20 days. The body of the larvae is translucent, dark green, covered with translucent mucus secreted skin. The anterior part of the body is greatly expanded; the larvae look more like small leeches. Previously, entomologists called them sawfly slugs. The head of the larvae is round and light brown. There are 7 pairs of abdominal legs, the last pair of legs on the 10th segment is underdeveloped. During the development period, the larvae molt 5–6 times.
Larvae of younger instars gnaw out the pulp of the leaf from the underside between the veins in small spots, and of older instars they skeletonize the leaves entirely, leaving only the network of veins intact. The larvae are inactive and cling tightly to the leaves. Planting into the soil begins at the end of June. The larvae pupate in dense oval cocoons made of soil at a depth of 5–15 cm.
In most regions, two generations of sawfly develop over the summer. Second generation larvae can be detected until mid-September.
Large-leaved linden (Tilia platyphyllos Scop.) and l. are highly resistant to the linden sawfly. felt (T. tomentosa Moench.).
Control measures
If larvae are found on the leaves, the plants are treated with an insecticide included in the list of pesticides and agrochemicals approved for use on the territory Russian Federation this year.
The cherry slimy sawfly is widespread throughout the non-chernozem zone. Damages cherries, sweet cherries, and less often plums, pears, rowan trees, bird cherry, and hawthorn. The adult insect (5 - 6 mm) is black, with two pairs of transparent, slightly darkened wings.
Larvae are greenish-yellow(9-11 mm long), covered with sticky black mucus. They look like small leeches with a thickened front part of the body ( table 48).
The larvae overwinter in the soil at a depth of 2 - 3 cm, under the crown of a tree, at a distance of about 1 m from the trunk. In June the larvae pupate in cocoons, and in July the adult insects emerge.
The female makes an incision with her ovipositor on the underside of the leaf and lays an egg in it. A swelling forms at the site where the egg is laid, and a brown tubercle is visible on the upper side of the leaf.

- pseudo-caterpillars that skeletonize leaves;
5
- false caterpillar
After 1-2 weeks the larvae hatch, which skeletonize small areas of leaves on the upper side. In this case, the soft parts of the leaf are eaten away and the veins remain intact. Damaged leaves turn brown and from a distance give the impression of being burned by fire.
In September The larvae go into the soil to a depth of 2-15 cm. In the non-chernozem zone, the sawfly develops in one generation.
As a result of damage by larvae, the leaves dry out. and fall off. When foliage is severely eaten, the trees weaken and the formation of flower buds for next year's harvest decreases.
Damage to young trees leads to a decrease in shoot growth. Sawflies are most dangerous to young seedlings.
How to deal with cherry sawfly
1)
loosening and digging of tree trunk circles in autumn and spring to destroy wintering larvae;
2)
spraying with infusions of tobacco, shag, wormwood, soda ash(70 g per 10 l of water) or 50% trichlorometaphos-3 (10 - 20 g per 10 l of water), 10% or 30% karbofos (75 - 100 or 25 - 30 g per 10 l of water ) with the massive appearance of larvae, which usually occurs after cherry harvest.
Not only we, but also about a dozen other pests, including the cherry slimy sawfly, lay claim to the cherry harvest. The larvae of this insect do not damage the berries themselves; they feed exclusively on leaf tissue, but with severe infestation they noticeably weaken the plant, which affects the yield. To effectively protect the garden, it is necessary to recognize the pest in time, determine the degree of damage to the trees, and apply proportionate control methods.
A “harmless” larva will leave only one skeleton of a leaf after 2–3 weeks of increased feeding
Insect development cycle
The cherry slimy sawfly is a hymenopteran insect; the main damage is caused by larvae that look like miniature black slugs. The same thickened head with a thoracic segment, only without horns, the body is covered with dark mucus. They also vaguely resemble leeches. Favorite food: leaves stone fruits- cherries, sweet cherries, serviceberry, hawthorn, sometimes it can move to rowan, quince, cotoneaster.
Like all insects, the sawfly develops cyclically. Gives 2 generations of offspring per year.
Adult (imago)
A common form of insect in our gardens is parthenogenetic, when only females are produced from the egg. Its length reaches 5–6 mm, the body and legs are black, the wings are transparent, slightly darkened, the size in span is 7–9 mm.
The flight of insects that pupated in autumn (the first generation) begins in May-June, the second generation, more numerous, flies out by the end of July.
Note! The life span of a female cherry sawfly from emergence from the pupa to death is 7–8 days. During this time, she manages to lay 50–70 eggs. The insect itself is harmless, since it does not feed additionally.
Larva
The period of embryonic development of the insect lasts 1–2 weeks, after which larvae hatch from the eggs. At first they are brownish-red in color, then covered with black mucus, as they grow they molt up to 8 times, reaching a length of 9–11 cm. The larval stage lasts from 15 to 25 days. Larvae hatched in August feed longer than the June generation.
Pests become firmly attached to the leaf and begin to systematically gnaw away upper layer pulp. The leaf blade is covered with characteristic spots with a translucent texture. The cherry sawfly, which infects the tree towards the end of summer, eats away the tissue so much that only the skeleton of the leaf remains, consisting of veins.
Doll
The larvae pupate in the ground at a depth of 7–15 cm. The offspring of the first generation leaves for the winter already pupated; it is they who fly out at the turn of spring-summer. Larvae younger age enter diapasis, pupae are formed in the spring, and adult insects begin to fly in the second half of summer.
Distribution and harmfulness
The insect is common in temperate climatic zone of the Eurasian continent, its biological forms are found in southern Africa, Australia, and South America.
The cherry sawfly is considered to cause little economic harm, so control chemicals carried out only if 25% of the leaves are affected. ABOUT mass destruction The tree is evidenced by the characteristic, as if burnt appearance of the foliage. In this case, biological processes are disrupted - the transformation of organic substances (photosynthesis), gas exchange, and moisture evaporation slow down. Accordingly, the plant becomes weaker, its immunity decreases, and productivity deteriorates.
Advice! You can find out whether the sawfly has reached the threshold of harmfulness with a simple visual inspection. It's time to sound the alarm if every fifth of the leaves randomly selected for the test is damaged.
Effective ways to fight
To protect the garden from the cherry slimy sawfly, both agrotechnical and biochemical control measures are used. If not large quantities pest control can be treated with preventive and folk remedies. Let's look at the most effective ones.
- Deep digging of tree trunk circles late autumn. This agrotechnical technique allows you to destroy most pupae and false caterpillars in a state of rest (diapause). When soil layers are turned over, they will fall to the surface and will be destroyed by birds or frozen out.
- Mechanical collection of larvae. The technique is used when growing small quantities low-growing varieties fruit crops so that it is possible to inspect each tree. It is clear that this method is effective if there are single specimens of the cherry sawfly.
- Chemical treatment of affected plants. Any insecticides designed to control pests of fruit crops are suitable - Confidor, Mospilan, Aktara, Inta-Vir, Calypso. It is also recommended to use pyrethroid preparations for spraying, the effect of which is similar to natural pyrethrins. For example, chamomile flowers contain them in large quantities.
Advice! The first generation of insects, which coincides with the fruiting period of cherries, can be poisoned with chamomile infusion. On a bucket hot water add 400 g of dried flowers and leave for 24 hours. The solution is filtered so that it sticks to the leaves, 30 g of dissolved tar soap is added.
- Use of biological drugs. These are bacterial insecticides based on toxic bacteria. Once in the body of the larvae, they cause paralysis of the intestinal tract, damage internal organs finally, the death of the pest. Differ from chemicals because they are harmless to humans and pets.
- Attracting entomophagous insects to the site. This is the name given to predatory insects that feed on their own kind, eating eggs and larvae. Danger for the cherry slimy sawfly are lacewings, blood-red soft beetles, and trichogramma that feed on eggs. To attract them to the garden, grow flowers in the area, aromatic plants– dill, mint, calendula, marigold, coriander. The sawfly does not like bright nasturtiums. If trunk circle plant with flowers, this will repel many pests.
- Pollination wood ash. Folk method gives results with a small infection of trees. Immediately after the rain, while the leaves are wet, they are pollinated with ash. When the larva comes into contact with it, it gets burned, and its appetite “deteriorates” significantly. After repeated application, most of the pests fall off.
Don’t give the cherry sawfly a chance - destroy the harmful insect with any accessible ways, otherwise your cherry will only have skeletonized leaves. If it was not possible to defeat the pest by early stages, after harvesting, spray the trees with pesticides.
How to deal with cherry sawfly:
It’s pleasant to walk through a pine forest - tall, slender trunks of pine trees rise up, green crowns rustle soothingly above, the air is filled with the smell of pine needles. The pine forest supplies man quality wood and resin, it holds the soil together with its roots and increases the humidity around, and its air is healing. The pine forest pacifies, brings peace and joy to the heart. By planting several pines in your dacha, you can create a small coniferous oasis for relaxation and peace, and it is very unpleasant when your pines are under threat. Besides fire and various diseases One of the main threats is the invasion of insect pests. Such pine pests are pine sawflies.
Description and types
Pine sawflies are insects belonging to the order Hymenoptera. Their range covers all areas where pine and similar trees grow coniferous trees. It is one of the most dangerous pine forests. 
Adult male and female are similar to flies or wasps, they differ from each other in appearance, as a rule, do not feed at all or feed on nectar. The main damage is caused by larvae that look like caterpillars, which is why they are often called false caterpillars.
Among pine sawflies, the most common pests of our forests are the common and red pine sawfly; these species are similar in many ways.
Ordinary
Adults: The female has a round body, color from red to light yellow, black head, black markings on the body, reaches a length of 10 mm. The male is smaller than the female, the body is thinner, the color is completely black, the antennae are fluffy.
They like to settle in young pine forests, but are found in a variety of pine and mixed forests. 
The eggs are oval, greenish, up to 1.5 mm, laid in last year's needles, covered with greenish-brown foam on top.
Larvae are the main pest. Color - from pale yellow to greenish, on the body there are black spots above each leg, grow up to 2.8 cm. They are held in nests, move and move synchronously.
The pupa is in a hard cylindrical cocoon of gray, brown or brown color, about 1 cm.
Did you know? The common pine sawfly was first described in 1758 by the founder of the species classification system, Carl Linnaeus, as Diprion pini. The rufous was described in 1785 as Neodiprion sertifer by the French zoologist Geoffroy Saint-Hilaire.
Ginger
Adults: The female has a round body, reddish color, reaches a length of 9 mm. The male is smaller, up to 7 mm, the body is thinner, the color is completely black, the antennae are feathery. Habitats are similar to the previous species. 
The eggs are oval, yellowish-white.
The larvae are gray in color, the head is black, there is a light stripe along the back with a border on the sides, on the sides there is a wide, black stripe with a light border, they grow up to 2.5 cm. The behavior is similar to that of an ordinary sawfly.
The pupa is in a hard cylindrical cocoon of yellow-golden color. Located in the forest floor until the emergence period.
Did you know? Females of the red pine sawfly are characterized by parthenogenesis-They can give birth to offspring themselves, without males. In this case, only male insects appear.
Life cycle features
The common pine sawfly grows one or two generations per year, depending on the latitude of its habitat; the emergence of the first occurs in late spring–early summer, the emergence of the second from mid to late summer. 
The female lays from 8 to 35 eggs at a time in cuts she makes on the needles, and covers them with a foamy coating for preservation. , as a rule, last year's, most often on the tops of the crowns. Then, after about 20 days, the eggs develop, and larvae emerge from them in 3–4 days.
The larvae hold on in large groups, eat off and grow. Depending on the daily temperature, the development period of the larvae ranges from 25 days at +26°C to two months at +10°C. Having finished feeding, the larvae form a cocoon and pupate.
The first generation attaches itself to the crown, development lasts 6–12 days, the second generation moves to the forest floor, where it overwinters. Adults emerge from pupae usually around noon.
The red pine sawfly grows only one generation per year; emergence occurs in late summer–early autumn. Females lay eggs on needles in increments of about 1.5 mm; on average, up to 100 eggs are produced on a shoot, and in outbreaks of reproduction up to 10,000 on one tree. 
Egg development ends in spring. The larvae behave similarly to ordinary sawflies. The duration of the development period depends on the temperature, from 30 days at +27°C to one and a half months at +13°C. The larvae in the cocoon lie in the needles of the forest floor until August, then pupate.
They overwinter both as larvae in a cocoon and as eggs.
Damage caused
Pine sawfly larvae eat the needles. During mass reproduction, the branches are densely dotted with larvae, one or two per needle. Young larvae eat the edges of the needles, leaving only the central vein and the top, while the needles dry out, curl and turn yellow.
The older larvae eat the needles completely, to the base. During growth, one larva eats from 30 to 40 needles, both young and old. As a result, the tops of the pine trees dry out, the trees slow down and become weaker, which leads to diseases and the infestation of tree trunk pests. 
Most often, young, up to 30 years old, plantings on hills, in warm, dry weather in late spring and early summer, are massively affected.
Important! The pine sawfly does not breed on fine-coniferous pine trees, such as Siberian and Weymouth pine, because the females cannot lay eggs on their needles. Crimean pine is also less susceptible to attack by this pest.
Control measures
When suitable conditions arise, an explosive increase in the number of pests occurs. Fighting pine sawfly on garden plot and especially in the forest is quite problematic; mechanical, chemical or biological methods.
In the forest
The degree of infestation of trees is determined visually by the number of larvae crawling along the trunks, by their waste products and by the number of cocoons in the forest litter. 
Mechanical measures: In the forest, removing larvae from branches manually is hardly feasible. The only thing that can be used is the creation of trap rings on the trunks that prevent the larvae from descending and crawling from the tree to the tree.
The rings can be sticky or killing when the trunk is wrapped in cloth containing the appropriate product.
Chemical measures: When large populations of pine sawfly are detected, as well as when there is significant damage to tree needles, it is rational to combat it with chemicals.
Trees are treated with systemic treatments that combine and internal contact actions, killing both when they come into contact with the pest and through food. It is advisable to use several different insecticides when processing. 
- - active ingredient - thiamethoxam;
- Kreotsid Pro, Arrivo - cypermethrin;
- Vermitec - abamectin;
- , Novaktion - malathion;
- , - pirimiphos-methyl.
The pine sawfly is well affected by the following biological preparations: Lepidobactocide.
Other biological methods are more likely to be preventive measures.
In the garden plot
If a pine sawfly appears in a dacha, the same control measures can be applied to it as in the forest, but in proportion to the need. In addition, methods are added that are not applicable in the forest due to the scale of the impact.
Mechanical: The simplest thing is to manually collect the larvae from the branches and trunk or knock them off with a strong stream of water. Larvae must be removed from the ground and under trees.
Important! In case of danger, sawfly larvae produce poisonous substance, causing an allergic reaction in people. Therefore, it is necessary to wear gloves when collecting larvae.
Biological: At the dacha you can use different folk remedies, the most famous of them are a concentrated infusion, a tobacco infusion mixed with and tops. 
Pour 250 grams of the selected product with a liter of water and leave for a day at normal temperature. After straining, the finished infusion is added to a bucket of water and the affected trees.
For the purpose of prevention and pest control, it is recommended to plant tomatoes near pine trees; their smell repels the sawfly. For the same purpose, you can attract natural enemies of the sawfly, such as insectivorous birds, by placing or luring them with sugar.
