【摘要】 采用野外试验的方法,比较了性信息素与化学药剂防治桃园梨小食心虫Grapholitha molesta的效果。结果表明,性信息素的防效普遍较化学药剂好。每666.7 m2设置性信息素诱捕器40只,虫果率为8.36%,防治效果83.15%。化学药剂连续防治3次,以1%甲维盐1 000倍液防治的虫果率最低,为9.19%,防效为81.49%。因此,性信息素可大范围用于桃园的梨小食心虫防治。更多还原

【Abstract】 The result of the field experiment in peach orchard showed the control effect of sex pheromone was better than that of chemical agents.The rates of the infested fruit and control effect of sex pheromone(40 traps per 666.7 m2) were 8.36% and 83.15% respectively.Among the chemical agents,the control effect of emamectin benzoate 1% 1 000 times was 81.49% and the rate of the infested fruit was the lowest(9.19%).So sex pheromone could be use to control Grapholitha molesta in peach orchards.更多还原
