Background technology
The resistance problem of pest is a global problem.Along with Chemical Control of Harmful Insects increase and the non-science of continuity, agricultural chemicals usage amount use agricultural chemicals, pest resistance is day by day serious, the pest species that produces resistance is on the increase.The Lepidoptera class pest of particularly causing harm serious to agricultural production, resistance level is higher, and resistance development speed is relatively very fast.Meanwhile, high-intensity use agricultural chemicals, causes that Practice for Pesticide Residue in Agricultural Products exceeds standard, environmental pollution and the increase of peasant's drug cost etc., is unfavorable for agricultural sustainable development.Therefore, the pesticide of efficient, the low toxicity of research and development, environmental protection has positive effect to agricultural sustainable development.
