What are the abilities of longhorn larvae? What is the larvae of longhorn beetles?

The larvae of the longhorn beetle are the larvae of insects of the family Coleoptera.

The larvae are coarse, oblong, slightly flattened, a few are slender, the head is broad or oblong, and it is often retracted into the dorsal plate of the anterior thorax very deeply. The larvae of the longhorn beetle eat the trunk and branches, affecting the growth and development of the tree, weakening the tree, leading to the invasion of germs, and it is also easy to be broken by the wind.

The basic ability of the larvae is to constantly gnaw on the trees, resulting in staggered insect passages in the trunk, which affects the transport of water and nutrients to the trees, reduces the wind resistance of the trees, and when the insect passages reach a considerable density, they will cause the trees to die or the main branches to break. The high density of longhorn larvae will become an important pest of regional greening. Therefore, it is necessary to control the adults early and eliminate them before they lay eggs.

In addition, for the larvae that enter the tree, it can be solved by injection administration or external plaster and tree rhizosphere soil application (systemic conduction type). In addition, in the germinal stage of adults, the density of adults can be reduced by using methods such as light trapping and trapping.

Basic abilities of larvae.

It is to constantly gnaw on the trees, resulting in the staggered insect passage in the trunk, which affects the transport of water and nutrients to the tree, reduces the wind resistance of the tree, and when the insect tunnel reaches a considerable density, it will lead to the death of the tree or the breaking of the main branch.

Ways to prevent it. Quarantine is imposed.

It is strictly forbidden to introduce dangerous longhorn beetles from abroad, outside the province, cities and counties through logs, packaging wood and insect-bearing trees.

Insect-resistant tree species. Different garden tree species and varieties have significant differences in resistance to longhorn beetles, so tree species or varieties with light damage should be selected.

Strengthen garden management.

Reason. Combined with pruning and pruning, timely pruning and treatment of insect dead branches; Trees with weak growth are susceptible to the damage of longhorn beetle, so forest management should be strengthened to promote the vigorous growth of trees and reduce the damage. Trees that are about to die or have died are cut down in time every year before the adults fly out, and the dead trees in the forest are thoroughly cleaned and treated.

Protect and attract predators.

The longhorn beetle has many predatory and parasitic predators, such as woodpeckers, magpies and other birds, swollen-legged wasps.

and other parasitic wasps, geckos.

and parasitic nematodes, which should be protected and utilized.

According to the content of the "Insect Record", it is clear that the larvae of the longhorn beetle have the ability to have a keen sense of taste.

Larvae of longhorn beetle, aliases, candida, mulberry, rodent, buffalo, star anise, horn worm, horn worm, iron cannon worm.

The larvae are worm-like, translucent to milky-white, and some species are relatively long (what Fabre called the "peristaltic small intestine") and eat away at trees, often causing bar-shaped bulges or cavities in the trunk, from which sawdust is discharged. The longhorn beetle is a general term for insects in the family Coleoptera, with long antennae, often exceeding the length of the body, and its larvae live in wood and can cause damage to trees or buildings.

Is <> this bug?

The larvae of the longhorn beetle are called grubs (qí chóng) and are a developmental stage of insects in the family Longhornidae. Grubs are the larval form of the longhorn beetle, they are herbivorous insects that feed on wood or the tissues of other yearish plants.

Grubs typically have a wriggling body morphology that exhibits a white to milky body color. They have a rigid exoskeleton that contains six long legs and a conical head with a letter of trousers. The size of the grub's body size varies depending on the species of the longhorn beetle and can range from a few millimeters to a few centimeters.

Grubs enter woody materials for defense and nutrient acquisition, and they use their powerful jaw teeth to bite wood fibers or plant cells. Grubs burrow through the wood to meet their needs for growth and development.

Grubs are an important developmental stage of the longhorn beetle species, and they inhabit wood or other plant tissues for a certain period of time until they enter the next stage of development, the pupal stage of the longhorn beetle. After the pupal stage, the mature longhorn beetle will hatch from the pupa.

Star Bull. The larvae of Xingtianniu are a traditional Chinese medicine, which can suffer from fever, sore throat, convulsions, malnutrition and heart disease.

The insect occurs in one generation in one year, and the larvae overwinter in the xylem of the victim host, and the overwintering larvae begin to be active after March of the following year, and March is mostly the rainy season.

It belongs to the coleoptera and cerambycidae beetle. The forewings of this group are keratinized, hard, and veinless, and are called "elytra", hence the name.

Coleoptera vary greatly in size and have hard walls; chewing mouthparts; antennae of various shapes, 10-11 segments; The anterior thorax is well developed, and the small shield of the mesothorax is exposed; The forewings are keratinous elytra, and the hindwings are membranous; The larvae are oligopod, and a few are apopoda.

Common insects (commonly known as): longhorn beetle, ladybug, firefly, fecal shell, cantharid, unicorn, gidding, coriander, beetle, stag beetle, kowtow insect, dragon lice, rice elephant.

Longicorn. It has long antennae, often exceeding the length of the body, and there 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, rolling sugarcane and hemp, etc., a few wood, buildings, houses and furniture, etc., are the main pests of forestry production, crop cultivation and construction wood.

Population distribution. There are many species of longhorn beetle, 22,000 species are known in the world, and there are about 2,200 species in China, which are widely distributed and harmful, and almost every kind of tree is affected by different species of longhorn beetle. The trees that suffered more damage were 28 species of mulberry trees, 25 species of willows and poplars, 18 species of citrus, and 23 species of pine trees.

In addition to the star beetle and the mulberry beetle, there are also bare-shouldered star beetle, peach-necked beetle, white-tendoned beetle, red-edged longhorn, cloud-spotted white-striped longhorn, bamboo-edged tiger longhorn, deep mountain longhorn and so on. Typical longhorn beetle species, the body is long cylindrical, the back is slightly flattened, the antennae are extraordinary, especially the more common ones, such as the star longhorn, the mulberry branch Qi longhorn, the cloud-spotted white-striped longhorn, etc., their strong body and protruding two horns, make people aware of the impression of the cow.

In fact, the size of the longhorn beetle is also quite varied, some have short antennae, some have oval or other shapes, and some imitate the image of other insects, such as the genus Rosa longhorn and the subfamily of the flower beetle, which are very similar to bees. The longhorn beetle is also known for its beautiful color, but many species are more or less tan, or arranged in spots, and the face of the trunk is early and oak, and has the effect of concealing or protecting the color.

<> beetles, the main targets are woody plants, and some longhorn beetles can also damage herbaceous plants, and the larvae of the longhorn beetle can eat away at the trunk, branches and roots. The larvae live mainly inside stems or roots, and there are also a few larvae that live in the soil to feed on the roots. If you find a branch parasitic with longhorn beetle, you can first cut off about 20 cm of the infested young stem and remove the dead plant, and then burn the dead plant or inject medicine into the insect hole.

1. What are the abilities of longhorn beetle larvae

1. The main object of longhorn beetle is woody plants, and some longhorn beetles will harm herbaceous plants, which will eat away at the larval stage of tree trunks, branches and roots. The larvae mainly live in the stems or roots, such as the chrysanthemum beetle, melon vine beetle, etc., and a small number of longhorn beetle larvae do not live in plant tissues, but live in the soil to feed on the roots, such as the big tooth and the curved tooth saw longhorn, grass longhorn, etc.

2. If you find that there are parasitic branches of longhorn beetle, you can first cut off about 20 cm of the damaged young stem and remove the dead plant, and then burn it intensively or inject medicine into the insect hole. If the stems and leaves suddenly wither in July and August, then the dead branches must be removed and then manually captured, and the damaged branches should be cut down and burned in time.

3. It is necessary to strengthen the cultivation management of crops, prune branches and leaves reasonably, pay attention to the variety configuration, and create a planting environment for biodiversity, because a proper shade environment can reduce the production of longhorn beetles more than a full-light environment.

Second, what medicine are the larvae most afraid of?

1. The larvae of longhorn beetle are more afraid of pesticides such as dichlorvos and trichlorfon. When the first instar larvae first enter the xylem, 20-30 times of insecticides such as dichlorvos and trichlorfon can be used, and the liquid can be injected into the worm tract with a large syringe. It can also be poisoned and killed by stuffing wormholes with mud or cotton balls, mothballs, etc.

2. In addition to dichlorvos, trichlorfon and other agents can prevent and control longhorn beetle, there are deltamethrin, cyfluthrin, 5% valvalerate, 40% dimethoate, 50% pine borer, 50% methamidophos, 50% phosphine, 40% phosphine, 48% lesben and other drugs have the same effect.

3. Be careful not to be bitten by the longhorn beetle during the prevention and control, the longhorn is not poisonous, but if it is bitten and bleeding, it will produce toxins, and the blood on the wound must be squeezed out immediately after being bitten, and then the wound is cleaned with soap and water.

<> beetle is also called rodent, rodent, day buffalo, star anise, horn worm, etc., there are about 2,200 species in China, which are widely distributed, and some areas have formed harm. What kind of worm was the cow that day? <

It is a herbivorous insect. The longhorn beetle will harm woody plants, most of which are walnuts, cypresses, pines, willows, elms, citrus, peaches, apples, tea, etc.; a portion of wheat, corn, sorghum, cotton, sugarcane and hemp, etc.; A handful of wood, buildings, houses and rolling furniture, etc.

It is a major pest in forestry production, crop cultivation and timber in the construction of the Great Building.
