摘要
病原真菌主要通过体壁侵染昆虫,在害虫防治中具有重要作用。利用昆虫病原真菌研制杀虫真菌农药的主要技术难点是选育高毒力杀虫真菌工程菌,本文综述了高毒力杀虫真菌工程菌构建技术的现状和菌株选育的进展,分析了其中存在的问题。根据昆虫病原真菌致病机制、害虫新靶标发现等方面的研究进展,提出了高毒力杀虫真菌工程菌选育技术的发展方向。
Entomopathogenic fungi infect insects mainly through cuticle,and have great potential in the biological control of pest insects.The key difficulty in utilization of entomopathogenic fungi as mycoinsecticide is to improve the strain virulence.The progresses in the genetic engineering techniques and the virulence improvements of insecticidal fungi were reviewed,and the existing problems were analyzed.Based on the developments in pathogenesis of entomopathogenic fungi and target discovery of pest insects,future directions for the genetic engineering of insecticidal fungi were put forward to improve fungal strain virulence.
