| Abstract: | 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,futur... |
