| 摘 要： | 为明确性信息素迷向技术对梨小食心虫的防治效果,在北京市平谷区桃园进行了该技术的防效试验,平均每公顷悬挂900根梨小食心虫迷向丝(4月和7月各悬挂1次)。结果表明,迷向丝对梨小食心虫各代成虫的迷向率可达84.62%~100%,且持效期在3个月以上,对各代幼虫蛀梢防效为77.78%~92.31%,蛀果防效为83.33%。同时,全年果园减少农药使用2次。因此,使用迷向技术可有效地干扰梨小食心虫的交配,减少后代的种群数量,从而减轻其危害。

| Abstract: | To explicit the control effect of mating disruption technology by using sex pheromone on Gra-pholitha molesta,the experiments were carried out in peach orchards in Pinggu district,Beijing. A total of 900 pieces of mating disruption wire were hung per hectare area in average ( hung twice,April and July, respectively). The results showed that the effects of mating disruption wire on each generation of Grapholi-tha molesta were between 84. 62% and 100%. The effects of avoiding top-breakage were between 77. 78% and 92. 31%,and the effects of avoiding fruit decay reached 83. 33%. The lasting period was more than three months. The annual frequency of pesticide use reduced twice. Therefore,this technology could prevent mating of Grapholitha molesta successfully during the entire growth period of peach tree,and reduce the population quantity of its offspring,thus reducing its damage. |
