Ectropis cinerarius botanical mating disruptor

The invention relates to an ectropis grisescens botanical mating disrupting agent, the mating disrupting agent comprises, by weight, 4-6 parts of capraldehyde, 4-6 parts of dodecanal and 0.8-1.2 parts of limonene, plant volatile matter components capable of disrupting the foraging and mating behaviors of ectropis grisescens are screened, and the optimal component proportion with good interference performance is obtained through a formula proportion optimization experiment. The interference agent has the characteristics of environmental protection, high prevention and control efficiency and the like, and can be used for preventing and controlling ectropis grisescens in a tea garden. Field tests for two consecutive years show that the number of ectropis grisescens in a tea garden can be reduced by more than 70% by slowly releasing the disrupting agent according to the dosage of 2.6 mL m , and the effect of continuously controlling the ectropis grisescens is achieved. 本发明涉及提供一种灰茶尺蠖植物源交配干扰剂，所述交配干扰剂的组成及重量比为：癸
