Abstract: To mitigate the harm of Cydia pomonella L.(codling moth) in apples,the mating disruption method of hanging silk in trees was studied.Results of the study showed that mating disruption can provide effective control of C.pomonella L.A control efficiency of 86.71% was obtained when silk was hung once.This decreased fruit damage and gave a significant economic benefit of 11 353 yuan per hm2.Hanging mating disruption silk twice further significantly reduced pests trapped and gave a mating disruption rate of up to 94.86%,and control efficiency of 95.83%.When silk was hung twice only 0.60% of fruit was damaged.Therefore,it is recommended that mating disruption silk be hung twice to improve the effectiveness of prevention.
