摘　　要：本文对白城市危害严重的果树食心虫种类及梨小食心虫天敌资源进行调查。通过对梨小食心虫生物防治试验研究,结果表明:由于白城市干旱少雨,不适宜线虫存活,寄生效果不好,不适宜大面积防治。采用在深秋或早春进行刮皮或细翻土壤等人工防治措施,虫果率平均下降28.95%;在卵期施用仿生制剂灭幼脲Ⅲ号、灭幼脲Ⅳ号、阿维菌素防治梨小食心虫,防治效果达90%以上。由于这几种制剂对环境及天敌安全,在果园中连续使用可保护自然天敌,逐步增强整个果园环境中天敌的控制作用,从而为生产无公害果品起到保障作用。The species of fruit borers those were seriously harmful in Baicheng City and the natural enemy resources of Grapholita molesta were investigated in this paper.The biological control test of Grapholita molesta was carried out.The results showed that due to the drought and little rainfall in Baicheng City,it was not suitable for nematodes to survive,and the parasitic effect was not good,so the biological control was not suitable for large-scale control.The percent of the damaged fruit decreased by an average of 28.95%after artificial control,such as scraping the bark or finely ploughing the soil in late autumn or early spring.In the egg stage,the biomimetic preparations,such as diflubenzuronⅢ,diflubenzuronⅣand abamectin,were used to control Grapholita molesta,and the control effect was more than 90%.These preparations were safe for the environment and natural enemies,so continuous use in orchards could protect natural enemies and gradually enhance the control of natural enemies in the entire orchard environment,and then ensure the production of pollution-free fruits.
