摘要
暗黑鳃金龟是目前农业生产上为害较重的地下害虫之一,而化学防治极易对环境和农作物造成污染,并对天敌昆虫产生伤害。生物防治以其无毒、无害、无污染、不易产生抗药性和高效等优点,在植物病虫害防治中越来越受到人们的重视。白僵菌是害虫生物防治中最重要的虫生真菌。分析了白僵菌的致病机制及影响因素,致力培养对暗黑鳃金龟专一性和致病性较强的白僵菌种,以期为暗黑鳃金龟的生物防治提供切实可行的方法。
Holotrichia parallela is one of underground pests seriously damaged agriculture production. Chemical control pollutes environment and crops, and is harm to enemy insects. Biological control has the advantages of non- toxic, harmless, non-pollution and high efficiency, which is paid more and more attention to. Beauveria bassiana is an important entomogenous fungi in biological control of pests. The pathogenic mechanism and influencing factors of B. bassiana arc analyzed. The B. bassiana strains with specificity and strong pathogenicity to H. parallela are cultured in order to provide feasible method for the control.
