摘　　要：虫生真菌在生活史各个阶段均面临多种环境因子的危害。为了避开这些不利的因素,虫生真菌进化出多种抗逆的机制。近年来,以球孢白僵菌(Beauveria bassiana)和金龟子绿僵菌(Metarhizium anisopliae)为代表的虫生真菌抗逆的生化分子基础的研究取得了一定的进展,明确了某些生化成份和抗逆基因与菌株抗逆性能的相关性。就环境胁迫因子、虫生真菌抗逆的生化分子基础及其在改良菌株抗逆性能方面的应用进行综述,这将为环境适应性强的虫生真菌制剂的研发与应用提供理论依据。Entomogenous fungi suffer harm from several environmental factors during every life-cycle stage. In order to escape the disadvantages,entomogenous fnngi form many stress-tolerance mechanism. Recent studies have made some progress in biochemical and molecular bases of stress-tolerance of Beauveria bassiana and Metarh＆ium anisopliae, and expound some biochemical components and stress-tolerance genes in association with the performance of strain stress-tolerance. The environment stress factors ~the biochemical and molecular bases of stress-tolerance of entomogenous fungi and their application in stress-tolerance improvement have been reviewed in this paper,which provided theoretical basis of the development and application of environmental stability fungal agents.
