What medicine is used for tree borers? What to do with bugs in trees?

Longhorn larvae can be sprayed with cyfluthrin and silicone is better. Be sure to spray evenly and beat throughout. The timing of the spray is critical, preferably just after the trunk of the tree is laying eggs.

It is also possible to inject the wormhole with high concentrations of the above pesticides at the same time. Some manufacturers' high-efficiency flufluthrin has insect attractants in it, and the effect is better, and it is generally the kind that fights underground pests.

Adult insects can be generally insecticides, such as emamectin benzoate series, avermectin series, and pyrethroid pesticides.

Generally, fruit trees are mainly aphids, mites such as red spiders, scale insects, psyllids, noctuidae and other lepidopteran pests.

Aphids: fruit trees are common in both the north and south, and the main control agents for aphids are imidacloprid and acetamiprid, etc., due to the low temperature in the north, acetamiprid and other effects are poor. At present, the recommended agents are chlorpyrifos, cyhalothrin and systemic agents, such as imidacloprid, thiamethoxam, dinotefuran, pymetrozine, etc., and spirometallethyl ester, halodioxapyr and other agents can also be used, which is recommended to be used in compounds.

Red spider and other mites: mites are also widespread, generally now used pesticides are avermectin, ethoxazole, spirodifenolate, cypermethrin, bifenazide, mineral oil, etc., it is generally recommended to use a variety of pesticides, citrus is generally used together with 3-4 kinds of pesticides, you can add some mineral oil appropriately, so as to improve the efficiency of insecticide.

Scale insects: At present, there is no good agent for the control of scale insects, and the promotion of phosphorus has been banned before, and the current products with good effects are chlorpyrifos, thiazinone, spirome ethyl ester, mineral oil, thiamethoxam, etc.

Psyllid, etc.: citrus psyllids in the south and pear psyllids in the north are important pests to fruit trees, and the prevention and control agents of psyllids are recommended as follows: chlorpyrifos, cyhalothrin and imidacloprid, thiamethoxam, dinotefurin, etc., which are generally used as fast-acting and long-lasting agents.

There are many species of insects on trees, which may be planthoppers, aphids, lacewings, bugs. You can use cypermethrin to prepare it in the specified ratio and spray it to control insects, and apply white lime to prevent moths after insect control. Or use chickens and ducks to eat the bugs and smear them with white lime.

mealybug, pseudococcidae; English name is commonly known.

Mealybugs, small sap-sucking insects, belong to the genus Mealybugs, which are distributed worldwide and adapt to a variety of environments. The female is oval, slow, about 1 cm long, and has a white sticky powder on the outside of the body.

Mealybug females and larvae cluster on the dorsal surface of the leaves. Male adults have a pair of well-developed forewings in the middle thorax and a well-developed reproductive sheath at the end of the body. Harm crops, fruit trees, gardens, forests and pastures.

The methods of prevention and control are:

Pick it off one by one with a toothpick, or "shovel" it from the side of the insect with a small paint brush, and then gently wipe the diseased plant repeatedly with alcohol, not only can remove the scale insects, that is, the larvae that are not clear to the naked eye, but also completely kill them, and rarely find the harm of scale insects in the second year, this method is simple, safe and effective.

Use vinegar (rice vinegar) 50

ml, as described above. This method is convenient and safe, which can not only achieve the purpose of insect control, but also make the damaged leaves green and shiny again.

3. Liquid soap: take soap and hot boiled water and spray it after dissolving it at 1:50, because soap can block the respiratory organs of pests until they die.

Generally, pesticides have a smell in the house, so it is recommended to use imidacloprid, which has no smell.

1. Apply whitening agent.

After the tree grows insects, you can apply a whitening agent to the trunk. Because most of the pests on the tree are hatched from the eggs in the cracks in the bark, after the pests appear, apply a whitening agent to the trunk to prevent the pests from continuing to reproduce and grow on the trunk, so as to achieve the purpose of eliminating the pest.

2. Water the liquor.

After the tree grows insects, you can also water liquor on it. First of all, you need to prepare a glass of white wine, mix it well with two glasses of water, and then mix the solution.

Watering the planting soil can eliminate all pests in the soil, and the roots of the tree can absorb the water containing liquor, which can also improve the resistance to insect pests.

3. Use vinegar.

After the tree grows insects, you can also use vinegar on the plant. That is, you can directly use a cotton swab or cotton ball, dip it in vinegar, and apply it to the area where pests are active on the trunk of the tree, and the pests can be eliminated. However, this method is only suitable for trees with a height of less than two meters, and it is not possible to remove pests from tall trees.

4. Spray the agent.

The easiest way to do this is to spray the trunk of the tree. First of all, you need to buy a special dimethoate from the market.

The insecticide, which is then diluted in the proportion on the package, is sprayed on the trunk of the tree where the pest is active, sprayed every other week, and after three consecutive times, the pest can be eliminated.

Then it depends on what kind of insect is born in the tree, and then the corresponding solution can be taken. There are many types of trees, and the insects are not the same, some insects can be killed by natural enemies, some insects can be killed manually, and some insects need to be controlled with drugs. In order to prevent insects from growing on the tree, you can clear the garden in winter to eliminate the source of insects, or spray stone sulfur mixture to kill pests and eggs.

chlorpyrifos, malathion, phoxanthion, trichlorfon.

chlorpyrifos, malathion, phoxanthion, trichlorfon.

1. Apply pesticides around the trunk to take targeted measures, and directly use pesticides to apply directly to the trunk of the insects according to the ratio. Some ordinary insects can't stand the smell of pesticides or some insecticides or eat them, and the insects will escape or die directly, which has the effect of killing insects. Even if there are some that can't be killed, at least the insects that don't come in will not burrow in the trunk and infest the tree when they smell the smell of these medicines.

2. There is a more effective way to pour pesticides into wormholes, which was often used before. It is to drill a hole connected to the wormhole in the trunk of the tree with insects, open the proportion of pesticides (insecticides), and then pour the prepared pesticides directly into the wormholes, and this method rarely survives the insects. The trunk is not afraid, as long as you apply more fertilizer, the trunk will grow back soon.

If the insects are not killed in time, the whole tree or the trunk with insects will slowly turn yellow and dry out. 3. Sawing off the trunk of a tree with insects, some have only one root to work on the main trunk, and a large part has several large trunks. If your tree has a lot of trunks, and one of them has bugs in it, in addition to the above practices, or the above practices are not good or do not use drugs, you can also cut off the trunk and cut it off.

But after sawing off, be sure to find the insect inside, otherwise it will climb on other tree trunks and harm other branches. 4. Coating the trunk of the tree with lime in autumn and winter, applying lime mortar to the trunk on the root of the tree is not only for the sake of beauty and identification, but also for the tree to prevent insects. In addition, it is also recommended to sprinkle lime on the dirt hills around the trees to improve the high acidity of the soil, and to prevent pests from incubating eggs on the way, so as to stifle insects from the eggs.

Tree roots can be prevented, you can prune the shade branches at ordinary times, and spray some preventive drugs regularly, which can kill some eggs that adhere to the surface of the trunk and prevent the reproduction of insects.

1. Caterpillars.

The caterpillar has 3 pairs of thoracic feet, most of the gastric feet and caudal feet are 5 pairs, and some larvae have a lot of poisonous bristles, and people will be red and swollen when they touch it. There are about 112,000 species, including moths and butterflies. Some of them can be used as bait and fish feeding, and are often active in leaves, trunks, etc., and are often found in spring and summer.

2. Scarab.

The larvae of beetles (grubs) are one of the main underground pests, which are seriously harmful, often biting off the seedlings of plants, resulting in yellow and death. A variety of adults are also major pests of crops, forest trees and fruit trees, so it is very important to correctly identify the scientific name of the species, study and grasp its taxonomic characteristics and biological characteristics, so as to control the harm of scarab and ensure the increase of agricultural and forestry yields.

3. Skyhorn. The chewing mouthparts of the longhorn beetle, which have long antennae, often exceeding the length of the body, are about 20,000 species worldwide. There are some species that are pests whose larvae live in wood and can cause damage to trees or buildings.

The longhorn beetle is a herbivorous insect, which will harm woody plants, most of the pine, cypress, willow, elm, walnut, citrus, apple, peach and tea, etc., some cotton, wheat, corn, sorghum, sugarcane and hemp, etc., a few wood, buildings, houses and furniture, etc., are the main pests on forestry production, crop cultivation and building wood.

4. Aphids. Aphids are also one of the most destructive pests on the planet. About 250 of these are pests that are serious for the agroforestry and horticulture industries. Aphids vary in size, ranging from one to ten millimeters in length.

5. Scale insects.

Scale insects, also known as "scale insects". Scale insects are an important pest of citrus and grapefruit, and the common ones are red round scale, brown round scale, Kang pian scale, sagittal scale and blow cotton scale. Scale insects damage leaves, shoots and fruits.

Scale insects are often male winged and can fly, and females and larvae once feathered, live on branches and leaves or fruits for life, causing yellowing of leaves, wilting of branch tips, decline of tree strength, and easy to induce coal pollution disease.

There are more insects on the trees.

For example, there are a lot of ants living in trees.

There are also various pests such as aphids, caterpillars, leaf beetles, beetles, ladybugs.

1. Fighting rice worms.

The rice worm is about the same size as the silkworm baby, and the whole body is milky yellow. In ancient times, people used 'a bucket of rice' to exchange for a worm, so it was called "bucket rice worm", also known as "birds do not deceive" and "tiger thorn wolf worm". The insect drills a small hole in the root of the tree, enters the tree, and eats the heart of the tree.

Second, the real image of chestnut chestnut.

The name of the insect belongs to the order Coleoptera, the weevilidae. It is advisable to have distribution in all chestnut producing areas in China. The host is chestnut plants, as well as plants such as hazelnut and oak. Adults bite young leaves, sprouts and young fruits; The larvae eat the cotyledons in the fruit, and the cavity is full of insect droppings.

3. Cockroaches. Cockroach is an omnivorous insect of the insect class Leatheroptera, also known as splints, clipping beetles, splint insects, or scissor insects, etc., cockroaches often live in the cracks of tree bark, decaying wood or under fallen leaves, and prefer a damp and dark environment.

Fourth, the European chestnut elephant.

The European chestnut elephant is an economically important forestry pest, which can cause devastating losses to chestnut and oak plants, seriously reduce the yield and taste of chestnut, and affect seed germination and seedling vigor. The insect is an oligophagous pest, and the hosts are mainly chestnut and oak.

Fifth, the poplar winged moth.

It is an insect belonging to the family Dipterogenidae of Lepidoptera, with an adult body length of 11 21 mm and a wingspan of 23 39 mm. Larvae Mature larvae are 30 mm long and cylindrical. Poplar moth is distributed in the northwest, north and northeast of China, and the damage to poplar microphylla and poplar is relatively light, and the damage to new varieties of poplar is relatively serious.

Caterpillars, beetles (beetles, beetles, unicorns, ladybugs...) Cicadas, aphids, ants, bees (wasps, bees...)

The tube worm should be the larvae of the moth seed, and only the larvae of the demoiselle moth can crawl around with a silk bag on their backs. Do you see if there are demoiselles around the tree?

These larvae usually eat ripe fruits and flowers, eat all the leaves, and hang the sacs on the tree. It is a very harmful pest.

You can try spraying insecticides, but the concentration is not too high, otherwise it will harm the tree. It is best to destroy the adults and larvae together, (moths are generally concentrated in bright places at night).

Hello dear, it is a pleasure to serve you. 1.Is it hidden in the trunk of the tree?

2.It also means that the fruit of our trees has a lot of insects. 3.

Or is it that there are a lot of insects on the tree, which specialize in gnawing on the branches and leaves of the young and tender ones? For different bugs, the methods we use are generally different.

In the fruit, there is a hole in the surface of the fruit, and when it is peeled off, there are worms inside.

What kind of fruit are you? Apples or what?

You're generally talking about a borer that often burrows into the fruit. In the spring stage of adult spawning sedan car, 2000 times of 25% urea suspension and 1000 times of 50% malathion can be used in the finger bend, and then the fruit can be sprayed.

Ask someone to dig it, get the stump off, and then deal with the small saplings that have grown up from the roots of the tree with 1 pack of 95% glyphosate TC + 2 packs of 2 methyl 4 chlorine bucket of water can achieve the effect.
