The antenna of longicorn beetle is usually nontoxic, but its saliva is toxic, so try to avoid it. Anoplophora longicorn is generally a pest, which mainly harms all kinds of wood. Trees invaded by longicorn beetles will weaken, shorten their life span and make it difficult to grow normally. Moreover, they will be vulnerable to other pests and diseases, and they will break easily when encountering strong winds. Therefore, it is necessary to spray 40% omethoate emulsion 300-500 times in time to control longicorn beetles.
1. Are the antennae of longicorn beetles poisonous?
1, the antenna of the longicorn beetle is generally not poisonous, but its saliva is poisonous, so you should avoid being bitten by it. If you are accidentally bitten, you need to deal with it in time.
2. Anoplophora longicorn is the main pest in forestry production, crop cultivation and building wood, among which the larval stage is the most harmful and the adult stage is the least harmful. When the inside of the tree is invaded by larvae, it will weaken the tree potential, shorten the life of the tree, lead to their abnormal growth, and when the harm is serious, it will make the tree wither and die quickly.
3. Trees eroded by longicorn beetles are often attacked by other pests and diseases, which makes them fragile and easy to break after encountering strong winds, and need to be prevented in time.
4. After finding the branches parasitized by longicorn beetles, it is necessary to cut off the young stems of about 20cm, and the dead plants also need to be picked and burned centrally. You can also spray 40% omethoate emulsion 300-500 times to control the larvae of longicorn beetles.
2. What shape is the antenna of longicorn beetle?
1. The antennae of longicorn beetles are generally whip-shaped, and the antennae are very long, often exceeding the length of the body. The antenna of the adult is attached to the protruding part of the forehead, which can rotate freely and turn backwards to cover the back of the worm.
2. Among the varieties of longicorn beetles, the antenna length of one kind of longicorn beetles can reach 4-5 times of its own body length, which is extremely long, but the antenna length of male and female beetles is different. The ratio of male body length to antenna is generally 1: 3-5, and that of female body length to antenna is generally about 1: 2.
3. The antennae of longicorn beetles are mainly used to detect the surrounding environment. For example, when encountering obstacles, they can sense the size, shape and hardness of obstacles through their antennae, and can also be used to sense the humidity, temperature and illumination of the environment. Some antennae of longicorn beetles also have the function of smell, and at the same time, longicorn beetles can transmit information to the same kind through antennae, which has many functions.
