American white moth control technology

1. Strengthen quarantine: seedlings in the epidemic area are not allowed to be transported outside the region without quarantine or treatment. Active prevention and treatment are carried out in the epidemic area to effectively control the spread of the epidemic.

2, artificial prevention: before the larvae 3 years old, found that the screen screen was manually cut off, and centralized treatment.If the larva is dispersed, the larva will be collected by the method of stringing the grass to the trunk before pupation, and the larva will be collected by a person at regular intervals.

3. Trapping and killing adults: use American white moth sexual attractant or environment-friendly insect attractant to trap and kill adults. Put the decoy core into the trap during the occurrence period of the adult, hang the trap in the forest, directly trap and kill male adults, block the mating of pests, reduce the reproduction rate, and achieve the purpose of eliminating pests.

4, chemical agents: in the larvae damage issue do early detection, early prevention, if there is a larva harms, the area to check it again, timely prevention, drug choice for biological control 0.12 propylene glycol esters algal acid (algae cover), 2.5% efficient cyanogen chloride fluorine chrysanthemum ester micro emulsion 1500 times spray, Bt emulsion 400 times liquid spray, efficient cypermethrin 2.5% ec 1500 times liquid, and can effectively control the pests.

5, biological control: zhou because bees is a new species, native to China, has become the natural enemies of the moths, the little bee can be found in a variety of hidden places pupate fall webworm, spawning parasitic fall webworm, this kind of high efficient, economic, pollution-free has passed the appraisal of bio-control research and technological achievements is the epidemic area accumulates promotion use.
