生物源农药在苹果蠹蛾防治中的应用

摘要

The codling moth, Cydia pomonella (L.) (Lepidoptera:Tortricidae), a notorious quarantine fruit pest worldwide, poses a serious threat to the main apple producing areas in China. In terms of food safety, environmentally friendly biological pesticides are desirable substitutes for chemical pesticides;the long￣term use of the latter have caused resistance, preventing its long team use for codling moth control. The present review summarized the use of biological pesticides, including parasitoids, sterilized insect, granu￣lovirus, entomopathogenic nematodes, Bacillus thuringiensis, entomopathogenic fungi, microsporidia, sex pheromone, cantharidin, and spinosad that have been either applied or suggested to control codling moth. The challenges faced by biological pesticides are al￣so discussed, and anyhow it will play an important role in the integrated pest management of codling moth due to its characteristics of infinite variety, wide source, good selectivity in application.%苹果蠹蛾是世界性检疫害虫，对我国苹果优势产区构成了巨大威胁。长期依赖化学防治使该虫抗性问题变得十分严峻。为了保障食品安全，以环境友好的生物源农药替代化学农药已成为当前苹果蠹蛾防治的热点。本文对国内外现有的生物源农药，如寄生蜂、不育昆虫、颗粒体病毒、病原线虫、Bt、病原真菌、微孢子虫、性信息素、斑蝥素、多杀菌素等，在苹果蠹蛾防治中的最新应用及其存在的问题进行论述，讨论了生物源农药凭借其种类多、来源广且在用药时期上选择性强等特点，在该虫综合治理中的重要地位及面临的挑战。
