迷向丝对苹果蠹蛾的防治效果研究

Control of Cydia pomonella L. in apples with mating disruption silk

为了减轻苹果蠹蛾的危害,采用迷向技术进行防治试验,结果表明:悬挂1次迷向丝防效达86.71%,增加收入11 353元/hm2,经济效益显著。悬挂2次迷向丝蛀果率仅为0.60%,迷向率高达94.86%,防效达95.83%。因此,悬挂2次迷向丝可以较好地控制苹果蠹蛾的危害,提高防效。

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.
