昆虫性信息素迷向法对桃园梨小食心虫防控效果研究

Control Effect of Mating Disruption with Insect Sex Pheromone on Oriental Fruit Moth in Peach Orchard

梨小食心虫是桃园的一种优势害虫。长期大量使用化学农药既杀伤天敌又使得害虫产生抗药性,为了推动果园害虫的无公害防治,笔者从2016年开始应用信息素对梨小食心虫进行迷向防治研究。从梨小成虫的发生情况、折梢率、蛀果率等方面进行调查。结果表明,迷向区梨小食心虫发生数量明显低于对照园且发生数量相对平稳,折梢率、蛀果率明显低于对照园,达到对梨小食心虫的防治效果。

Oriental fruit moth is a dominant pest in peach orchard. The long-term useness in large quantities of chemical pesticides not only kill natural enemies,but also make pests resistant. In order to promote harmless control of orchard pests,from 2016 ,the author applied Sex pheromone to study on mating disruption control of oriental fruit moth. The investigation was made on occurring dynamics, rate of damaged shoots, rate of bored fruits for oriental fruit moth. The results showed that, in mating disruption control orchard,The number of oriental fruit moth is significantly lower than that of control orchard ,and the number of occurrence is relatively stable. The rate of damaged shoots, rate of bored fruits are significantly lower than that of the control orchard. The control effect of oriental fruit moth has achieved.
