The longhorn beetle is a pest, is a major pest in forestry production, crop cultivation and construction timber. Among them, the larval stage is the most harmful, and the adult stage is the least harmful. In addition, the longhorn beetle is a herbivorous insect known to feed on pollen, tender bark, twigs, leaves, roots, sap, fruits, and fungi.

and other different habits, the longhorn beetle often feeds on pollen, and the ditch tibial longhorn often eats the tender bark.

The longhorn beetle is a herbivorous insect that can 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 timber, buildings, houses and furniture, etc., are the main pests of forestry production, crop cultivation and construction timber.

Habits

The longhorn beetle generally overwinters in the trunk of a tree as a larvae or adult. After the adult worm emerges, some need to supplement nutrition, eating pollen, young branches, young leaves, bark, sap or fruits, fungi, etc., and some do not need to supplement nutrition. The lifespan of adults is generally more than 10 days.

up to 1 2 months; But adults overwinter in the pupal chamber for up to 7 to 8 months, and males have a shorter lifespan than females.

The activity time of adults is related to the thickness and thinness of the small eye surface of the compound eye, which is generally thick, mostly active at night, and has phototaxis; Those with small eyes and thin faces are mostly active during the day. The oviposition mode of adult worms is related to the form of mouthparts, and generally the adult of the anterior mouth type lays eggs directly into the rough bark or cracks when laying eggs; The adult worm with a lower mouth first bites into a groove on the trunk of the tree and lays its eggs in the groove.

The longhorn beetle is a pest. Because the longhorn beetle is the main pest of forestry production and crop cultivation, they mainly eat plant trunks, branches and leaves in the larval and adult stages, and also endanger building materials, house furniture, etc., among which the adult mainly eats pollen, tender bark, twigs, leaves, plant roots, sap, plant fruits and fungi, etc., so it is a pest.

The longhorn beetle, an insect belonging to the Coleoptera longhorn family, it 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 small number of wood, buildings, houses and furniture, etc., are the main pests of forestry production, crop cultivation and construction timber. As long as you don't scratch it, you won't take the initiative to bite, and even if you scratch it, as long as you pinch its back with two fingers, you won't be bitten. Even if you are bitten, it is not poisonous, and it will not hurt after a group, and no special treatment is required.

The longhorn beetle is a pest.

The longhorn beetle is the main pest of forestry production and crop cultivation. It is very harmful in the larval stage and less harmful in the adult stage. The longhorn beetle is a herbivorous insect, and its diet is mainly pollen, tender bark, young branches, leaves, roots, sap, fruits, fungi, etc.

Most longhorn beetles choose to harm crops such as pine, cypress, willow, elm, walnut, citrus, apple, peach and tea, and a small number will harm crops such as cotton, wheat, corn, sorghum, sugar cane and hemp. The daily activity of the longhorn beetle is to gnaw on the trunks, branches and leaves of plants, etc., and it can also endanger building timber, house furniture, etc.

When controlling the beetle, woodpeckers can be raised in places where there are more longhorns, because woodpeckers are the natural enemies of longhorns. In addition to breeding woodpeckers can control the longhorn beetle, the tube swell-legged bee can also, the adult of this bee is very similar to ants but like bees, it is the natural enemy of many moth-eating pests, especially the longhorn beetle, it can control the number of longhorn beetle pests very well.

Pests

Pests, as the name suggests, are harmful insects, which are the definition of some insects by humans, as opposed to beneficial insects, which are mainly divided into insects and non-insects, and there are many types and quantities. Pests that often appear in life, such as mosquitoes, flies, fleas, cockroaches, etc.; These small creatures often have a negative impact on human life and production.

01 Pests.

The longhorn beetle is the main pest of forestry production, crop cultivation and construction timber, among which it is the most harmful in the larval stage and the least harmful in the adult stage. Longhorn beetle is a herbivorous insect, known to have different habits of feeding pollen, tender bark, young branches, leaves, roots, sap, fruits, fungi, etc., the longhorn beetle often feeds on pollen, and the longhorn longhorn often eats tender bark, twigs and leaves.

The longhorn beetle is a pest, it will harm woody plants, most of the pine, cypress, willow, elm, walnut, citrus, apple, peach and tea, etc., some cotton, wheat, corn, sorghum, sugar cane and hemp, etc., a few wood, buildings, houses and furniture, etc.

The longhorn beetle is a general term for insects of the multiphagous suborder longhorn beetle, and there are some species that are pests, and their larvae live in wood and may cause damage to trees or buildings. It is also a herbivorous insect, which can 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 of forestry production, crop cultivation and building wood.

In production practice, the working people of China have known for a long time that the longhorn beetle is a pest that eats trees. The larval stage is the most severe damage to plants, and although adults can sometimes cause more or less damage due to egg-laying and feeding on branches and leaves, it is generally not serious.

The longhorn beetle must be a pest, if there is a longhorn cow in the house, it must be a way to get rid of it, because this longhorn may fly in from the outside, but you don't have to worry, although the longhorn is a pest, but it is not a poisonous insect, so being bitten by the longhorn beetle, although it is more painful, but it will definitely not pose too much threat to our health. <>

The larvae of the longhorn beetle actually feed on the xylem of many plants, and the adults of the longhorn beetle will also feed on a small amount of plant xylem, so once the pest of the longhorn beetle appears, the damage to the plant is very great. For example, our family has planted a lot of figs in a large area before, and the fruit tree of figs is actually very easy to attract the longhorn cow, once the longhorn beetle appears, the fig fruit tree will be greatly affected, and sometimes it will even be directly disconnected from the middle, because the boring branches of these figs have already been gnawed by the longhorn cow. <>

Therefore, once the pest of the longhorn beetle is found, it must be eliminated without hesitation, and the best way to eliminate the longhorn beetle is actually to spray the insecticide directly. Of course, some fruit trees may be affected to a certain extent after spraying pesticides, after all, the fruits and vegetables are pure green and natural. At this time, we can only rely on manual efforts to eliminate these natural flows, and it is usually recommended that you can get up earlier in the morning, because this time period is the time period for the activities of the longhorns, and you can manually catch these daybulls in the orchard.

Under normal circumstances, these bulls will definitely not take the initiative to attack humans, although the appearance of the bulls is more hideous, but in fact the bulls will not attack us, so you can rest assured when catching these cows, if you are really scared, then we can bring a pair of gloves, which will be safer. After the completion of the heavenly cow, we will gather together to destroy, for example, you can directly put it in the brazier and burn it to death. Changfu.

The longhorn beetle is a very powerful insect, its main food is to eat plants, the flower longhorn is mainly pollen-based, and the ditch tibial longhorn beetle eats tender bark, twigs and leaves. The longhorn beetle is a pest that eats away at plants, affects the development of trees, and finally kills trees.

The adults of the longhorn beetle mainly eat pollen, young bark, young branches, leaves, plant roots, sap, plant fruits, and also eat fungi. Different types of longhorn beetles eat differently, such as the flower longhorn beetle, which is the kind we are more common, it mainly eats pollen, and the other is called the ditch tibial longhorn beetle, which mainly eats tender bark, tender branches and leaves, how harmful do you say this is to trees? Therefore, many places will hunt and kill the longhorn beetle because it is too harmful to agriculture and animal husbandry.

According to the records, the methods of controlling the longhorn beetle include searching and killing insect eggs, hooking and killing larvae, applying pesticides to insect holes, and killing adults.

The bull is good to eat plant things, and the cow is not picky, and the cow has a lot of strength, because the cow is as strong as a cow, and can also fly in the sky, got the name of "the cow". Therefore, the longhorn cow eats very fiercely and never picks its mouth. For example, pine, cypress, willow, and elm are eaten, and even walnuts, citrus, apples, peaches, and tea are eaten, and crops such as cotton, wheat, corn, sorghum, sugar cane, and hemp are eaten, and the longhorn ox eats timber, buildings, houses, and furniture.

In this way, the longhorn cow is simply pervasive, and according to its one bad behavior, it is not an exaggeration to position it as a pest, right? The longhorn itself is not poisonous, but after being bitten by it, it is poisonous, and it must be squeezed out in time to bleed, otherwise there will be discomfort in the body, so it is not only a pest, but also harmful to people's physical safety, and we must do a good job of preventing it every day.

When you go to play in the wild, you must take protective measures and don't let children touch it and be bitten by it, it will be very troublesome. In addition, the longhorn beetle can also be used in medicine, and the price of a good longhorn beetle is not low.

The longhorn beetle is both a pest and a beneficial insect. This is because some longhorn beetles can cause damage to vegetation such as forests, fruit trees, etc., and thus are called pests. On the other hand, some longhorn beetles also play an important role in helping to disturb the balance of the chain bark forest ecosystem, and are known as beneficial insects.

Some longhorn beetles can affect the health of forests and fruit trees, and they can eat plant leaves or seedlings, harming forests and crop production. For example, the Yunnan Araucaria longhorn beetle will harm fir trees, and the long-beaked pine longhorn beetle will harm Korean pine, North China five-needle pine and other tree species. Other longhorns help to decompose dead trees, improve soil fertility, control pest populations, etc.

For example, the forest sawing beetle has a long life span and a large number of eggs, and it can be controlled by the unfavorable environment of the wrong season to achieve a state of natural balance with the habitat, and finally produce the effect of ecological network.

Therefore, for the question of the longhorn beetle, we can conclude that it is both a pest and a beneficial insect. There are many species of longhorn beetles, some of which are harmful to humans and plant hosiery, while others are beneficial to forests and agricultural production. In practical application, the number of pests should be reduced as much as possible, and the types of beneficial insects should be protected in a targeted manner, so as to maintain the balance of the ecological chain.
