How to eliminate bedbugs

Give priority to manual control, pay attention to protecting natural enemies, and use chemical control when necessary.

Manual control:

Adults and nymphs often inhabit leaves or fruits outside the tree crown in the morning and evening or in rainy weather, and can be killed in the early morning or evening when the dew is still wet and inactive. Eggs are mostly found in egg blocks on leaves and are easy to find. The eggs can be removed in time during the spawning period from May to August.

However, it is found that there is a black ring under the egg cover, which indicates that the egg has been parasitized by parasitic bees, so it should be protected in the field to make it reproduce naturally and increase the number of parasitic bees in the orange orchard.

Chemical control:

If the insect population is too large to be solved by manual control, spray 800 ~ 1000 times dilution of 90% trichlorfon crystals. If some pine alkali mixture is added to trichlorfon solution, the control effect can be improved, and it can be controlled in both the first and second instar nymph stages, and the effect is better.
