What do longhorn beetles eat? What food does the longhorn cow eat

The longhorn beetle is a well-known pest with its chewing mouthparts, and its larvae live in wood and can be harmful to trees or buildings. Adults generally like to be active at night, phototaxis, because the longhorn beetle is very harmful to crops and fruit trees, so farmers are also very afraid of it, so what does the insect longhorn beetle eat? How should the longhorn beetle be controlled?

Let's take a look!

1. What does the insect beetle eat?

The longhorn beetle is a very powerful insect, which will harm a variety of woody plants, the more common pine, cypress, willow, elm, walnut, citrus, apple, peach and tea and other trees often have longhorn beetle, cotton, wheat, corn, sorghum, sugarcane and hemp will also occur in the beetle. The longhorn beetle can eat pollen, tender bark, leaves, roots, sap, fruits, and much more.

Second, how to prevent and control the longhorn beetle?

General control of longhorn beetle, need to be carried out when its larvae, so that the effect can achieve the best, longhorn beetle generally lays eggs on the branches, some species of egg-laying grooves are obviously easy to find, young larvae are not bored into the xylem before, there is fresh sap resin outflow on the branches, there are reddish-brown feces, scrape the bark with a sharp knife, carefully search, kill the eggs and larvae, or use a hammer and other knocks, or apply pesticides. This method is only suitable for species with low branches, oviposition grooves and instar larvae.

When the larvae grow up, they bury into the xylem, and often discharge feces and sawdust from the fecal discharge hole, and can be used to extend the iron wire into the boring hole, hollow out the fecal chips in the hole, and hook the larvae. Some longhorn beetles have dozens of manure holes, which need to be hooked into the last holes. This method is easy to hook and kill the longhorn beetle with straight cavities, but it is difficult to hook and kill the longhorn beetle with crooked cavities, and there are many chemical industries, and the damage to the tree body is greater, so it is not suitable for continuous use every year.

The main food of the longhorn beetle is plants, because the longhorn beetle itself is a kind of pest that eats plants, so the diet of the longhorn beetle is relatively simple, mainly plant-based.

The longhorn beetle is mainly a pest of woody plants, eating away at tree trunks, branches and roots during the larval stage. Some of them are harmful herbaceous plants, and the larvae live in the stems or roots, such as chrysanthemum beetle, melon vine beetle, etc. Some species, such as the cotton capsule, are harmful to the cotton capsule.

There are also a few species where the larvae do not live in plant tissues, but feed on roots in the soil, such as the big tooth and the curved tooth saw longhorn, the grass longhorn and so on.

The main food of the longhorn beetle is to eat plants, the flower longhorn beetle is mainly pollen-based, and the groove tibial longhorn beetle eats tender bark, young branches and leaves. The longhorn beetle is a pest that eats away at plants, affects the development of trees, and finally kills trees.

The longhorn beetle is a herbivorous insect and eats woody plants, mostly pine, cypress, willow, elm, walnut, citrus, apple, etc.

The longhorn beetle can eat the branches, stems, or roots of plants, as well as pollen, fruits, fungi, apples, walnuts, citrus, tea, honey, etc.

The food of the longhorn beetle is different from that of the adult stage, and different species of longhorn beetle also have different dietary habits. In the larval stage, the longhorn beetle can eat the trunks, sails, branches, stems or roots of willows, acacias, and fruit trees. During the adult stage, the longhorn beetle will have different habits depending on the species.

Some will eat pollen, tender bark, young branches, young leaves, young roots, and some will eat tree sap, fruits, fungi, etc.

For the domestic longhorn beetle, it can be provided with apples, walnuts, citrus, tea, corn, sorghum, wheat, sugar cane, honey and other foods. The longhorn has great strength, and the longhorn is as powerful as a cow and can also fly in the sky, so it got the name of "skyhorn". Therefore, the longhorn cow eats very fiercely and never picks its mouth.

The types of longhorn beetles are:

1. Tiger longhorn: Tiger longhorn is a pest, an insect of the genus Coleoptera longhorn beetle, mainly including dawn tiger longhorn, mulberry tiger longhorn, grape tiger longhorn, green poplar ridge tiger longhorn, etc., adult insects appear in summer, live in the middle altitude mountainous area.

2. Saw beetle: The saw is an insect of the genus Sawworm in the family Longhornaceae, and the main host plants are conifers, pines, cedars, cypresses, oaks, beech, etc., which are distributed in Northeast China, Inner Mongolia, Hebei, Zhejiang, Sichuan, Taiwan and other places.

3. Slender longhorn: Slender longhorn beetle is an insect of the genus Slender longhorn of the family Longhorn family, and the main host plants are fir, spruce, linden pine, ichthyosis pine and other pine plants, which are distributed in Northeast China, Zhejiang and other places, and distributed in the Soviet Union, North Korea, Sakhalin, Japan and other places.

The longhorn beetle feeds on plants and can eat the branches, stems, or roots of plants, as well as pollen, fruits, fungi, apples, walnuts, citrus, tea, honey, etc.

The diet of the longhorn beetle is relatively simple, and it mainly feeds on plants. In the larval stage, the longhorn beetle can eat the trunks, branches, stems or roots of willows, acacias, and fruit trees. In the adult stage, the longhorn beetle has different habits such as pollen, tender bark, young branches, leaves, roots, sap, fruits, and fungi depending on the species.

For the domestic longhorn beetle, it can also be provided with apples, walnuts, citrus, tea, corn, sorghum, wheat, sugar cane, honey and other foods. In short, without mutation, the longhorn beetle only eats plants.

There are many types of longhorn beetle, the common ones are star longhorn, mulberry longhorn laughing song, bare-shouldered star longhorn, white-tendoned longhorn, deep mountain longhorn longhorn and so on. Usually in the larval stage, the body of the longhorn beetle is pale yellow or white, and the body will be long cylindrical when it grows into an adult.

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 to 1 2 months; Adults overwintering in the pupal chamber can reach 7 to 8 months, and the lifespan of males is shorter than that of 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.

1. Food type: mainly eat young leaves, fruits and pollen. 2. Prepare the container:

The tentacles of the longhorn are hard, and an airtight wooden box or iron box should be prepared. 3. Provide drinking water: sprinkle water in the box to ensure humidity.

4. Temperature environment: Place the longhorn beetle in a place where the temperature is above 15 degrees Celsius to grow to avoid freezing.

1. Type of food

When feeding, you can feed willows, acacias, fruit tree trunks, branches, or provide apples, walnuts, corn, sorghum, honey and other juicy foods for the longhorn beetle.

2. Prepare the container:

The longhorn beetle likes to grow parasitic in the wood and has strong burrowing, so it is necessary to choose a transparent and sealed box during the breeding process, or use a wooden box with tight connections between the wooden planks to provide a good growth environment for the longhorn beetle.

3. Provide drinking water

Although the demand for water is not high, it is necessary to sprinkle water frequently into the box to ensure humidity when feeding, or you can put a water-absorbing sponge in the wooden box to create a moist environment for the longhorn to dry up and die.

4. Temperature environment

The longhorn beetle is not suitable for growing in a low temperature environment, and the temperature needs to be controlled above 15 degrees Celsius, and when the temperature is too low in winter, the box should be wrapped with cotton cloth to prevent the longhorn beetle from freezing and slowing down.

The longhorn beetle feeds on pollen, young branches, young leaves, bark, sap or fruits, fungi, etc., and the longhorn beetle mainly eats larvae, lives for the longest time, and harms the trunk the most severely. When the eggs hatch into the larvae, the first instar larvae burth the trunk;

At first, they feed under the bark of trees, and when the age increases, they burrow into the xylem to cause harm, and some species only live under the bark and do not moth the xylem. The larvae move within the trunk of the tree, and the shape and length of the moth-eating tunnels vary from species to species.

The larvae feed on the trunk or branches, opening their mouths into the bark at a certain distance as vents, pushing out excrement and wood chips. After the larvae are mature, they build a wide pupal chamber, which is blocked with fibers and sawdust at both ends, and pupates in it, and the pupal stage is about 10 to 20 days.
