| 为了评价梨小食心虫迷向素的实际防控效果，在大面积连片使用梨小食心虫性迷向素的北京市平谷区（约8667 ha），分别选择王辛庄镇翟各庄村、东杏园村和峪口镇西营村的3个处理果园。以临近的采用常规化学防治的顺义区杨镇小曹庄村为对照，采用性诱剂和糖醋液监测调查比较桃园梨小食心虫的发生动态、抽样法调查统计桃树蛀梢率和蛀果率等，评价性迷向素梨小食心虫田间控制效果。结果显示，迷向素处理区梨小食心虫的种群数量显著低于常规化学防治的对照区。3个迷向素处理区梨小食心虫的迷向率分别为99.05%、98.10%和99.68%；保梢效果均在98.40%以上，保果效果几乎达到100%。说明桃园大面积应用迷向技术对梨小食心虫具有很好的控制作用。 |

| In order to evaluate the actual control effect of disrupting mating with sex pheromones to Grapholiths molesta (Busck), the sex pheromone was used in large area peach orchard (approximate 8667 hectare) of Pinggu district in Beijing that including Zhaigezhuang, Dongyingyuan and Xiying village. Sex attractants and sugar-vinegar liquid were used to monitor the population dynamics of G. molesta as compared with chemical control area of Xiaocaozhuang village in Shunyi district. In order to evaluate the control effect of disrupting mating with sex pheromone toG. molesta, the rate of tip decay and fruit decay of peach tree were investigated. Our results showed that the population number of G. molestain sex pheromone treated area was significantly lower than in the chemical control area. The mating disruption rate ofG. molesta in three treated area were 99.05%, 98.10% and 99.68%, respectively. The peach fruit-preserving effect was achieved to 100%. Our results demonstrated that the good control effect of disrupting mating with sex attracts to G. molestawhen it was used in large area in peach orchard. |
