Control methods of longicorn beetles

Four methods can be used to control longicorn beetles: natural enemies, physical control, chemical control and forestry control, among which physical control and chemical control are common methods in daily life. Physical control mainly uses artificial killing, garden cleaning, flooding and other methods, generally catching longicorn beetles after rain, chemical control is to use cotton to absorb dimethoate EC, dichlorvos EC and other agents into the wormhole to kill, generally the best control in June.

How to control longicorn beetle larvae?

1. Strengthen management: strengthen cultivation management, reasonable pruning, pay attention to the allocation of varieties, and create a biodiversity planting environment, because the damage caused by tiger longicorn beetles is less in the appropriate shaded environment than in the full-light environment. Strong fruit trees have a certain insect resistance.

2. Timely treatment: when the parasitic branches of longicorn beetles are found, about 20 cm of the injured young stems can be cut off and the withered plants can be removed, burned centrally or injected into the wormhole, and the withered branches can be cleared when the stems and leaves suddenly wither from July to August, be caught manually and cut off and burned in time.

3. Poison the larvae: when the first instar larvae enter the xylem, 20-30 times of the sand insecticides such as dichlorvos and trichlorfon can be taken, and the solution can be injected into the insect path with a large syringe. In production, there are also slime or cotton balls, camphor balls and so on stuffed into wormholes to kill larvae.

4. trunk whitening: 10 parts of quicklime, 1 part of sulfur powder, 0.2 parts of salt, 0.2 parts of cow gum (pre-hot water melting), 30-40 parts of water or 0.2 parts of trichlorfon are mixed into whitening agent, which is applied within 2 meters of the lower part of the tree trunk from the ground.

5. Chemical control: such as 2.5% deltamethrin, 2.5% cyhalothrin, 5% fenvalerate, 90% trichlorfon crystal, 80% dichlorvos, 40% omethoate, 50% fenitrothion, 50% methamidophos, 50% phoxim, 40% phoxim, 48% Lesbon, etc.

The above is the relevant introduction of longicorn beetle control methods, I hope it will be helpful to everyone.
