The appearance of beetle larvae and adults is different. The larvae are thicker, oblong, and slightly flat. There are also a few beetles that are elongated. The adult has a long cylindrical shape, with a slightly flat back, and its antennae can rotate freely and are attached to the protruding part of the forehead. At the same time, the body length of beetles is also related to the species. For example, the body length of big mountain saw beetles is generally about 110 mm, while the body length of micro beetles is only about 0.5 mm.

1. What does a longhorned beetle look like

1. The longhorned beetle larvae is light yellow or white in color, has a thick, oblong body, is slightly flat, and is the size of a few longhorned longhorned beetles. It is elongated and has a broad or oblong head.

2. The adult beetle has a long cylindrical shape with a slightly flat back. Its tentacles are attached to the protruding part of the forehead. The tentacles can rotate freely and can also cover the back of the insect backward. On the upper body, the claws are usually single-toothed, and a few beetles have attached-toothed claws.

3. Different types of beetles also have certain differences in their body lengths. For example, the body length of the big mountain longhorn beetle is generally about 110mm, while the body length of the tiny beetle is only about 0.5mm. However, most beetles are large or medium-sized, with body length generally between 15-50mm.

2. What environment is suitable for longhorned beetles to live in

1. Longhorned beetles often overwinter in tree trunks as larvae or adults, which can harm pine, cypress, willow, elm, etc. Trees and some beetles can harm crops such as corn, sorghum, and sugar cane. Beetles can also be seen in a small number of timber, buildings, houses, and furniture.

2. Longhorn beetles are major pests in forestry production, crop cultivation and construction timber. The larvae will eat tree trunks and branches, affecting the growth and development of trees, weakening the trees, and allowing pathogens to take advantage of them. When the damage is serious, it can easily lead to the death of the entire plant. When the wood is eaten by woodworms, it loses its craftsmanship value, so it is necessary to prevent and control beetles in time.

3. Generally, moth balls can be used to kill beetles. You can first crush the moth balls into powder, and then stuff the moth ball powder into the worm holes. The dosage per hole is generally 1/5-1/4 grains. . You can also kill beetles by blending mothballs into alcohol, gasoline or diesel, then dipping them in absorbent cotton and stuffing them into insect holes.

4. Before the adult beetles emerge from their holes, spray 80% dichlorvos emulsifiable concentrate on the main branches, trunks, and root necks every one week to ensure that the liquid can flow along the trunk to the roots. Usually the effectiveness of controlling beetles can reach 80%.
