摘　　要：2007年在陕西省蒲城县梨园用3种性信息素对梨小食心虫进行了迷向防治试验。结果表明,日本迷向丝和中捷性诱芯对梨小食心虫有很好的迷向效果,且方法简单,持效期长,无公害。在不喷化学农药条件下迷向处理37 d后,25根/667 m2迷向丝对梨小食心虫的迷向率达97.19%,防效为81.61%;200枚/667 m2中捷性诱芯的迷向率为93.46%,防效为73.72%;由此可见,迷向丝和中捷性诱芯可推广应用于梨小食心虫的防治工作中。Experiments of mating disruption were conducted to control Grapholitha molesta Busck by using three sex pheromones in pear orchard in Pucheng,Shaanxi in 2007.Results showed that Japanese sex pheromone and sex pheromone lure were very effective to Grapholitha molesta Busck,and also easy,lasting and safe.After 37 days,under no insecticide,the rate of mating disruption was 97.19% and 93.46%,the control effect was 81.61%and 73.72% when treated with 25 Japanese sex pheromones per 667 m2 and treated with 200 sex pheromone lures per 667 m2,respectively.Thereby,Japanese sex pheromone and sex pheromone lure can be used control Grapholitha molesta Busck.
