昆虫病原真菌在农林害虫生物防治中的应用

长期以来,昆虫病原真菌作为一类重要的生防资源,在农林害虫种群自然调节中发挥了重要作用。综述了昆虫病原真菌资源的利用情况、对害虫的侵染致病机理及主要属种在农林害虫生防中的应用现状,分析了昆虫病原真菌防治中的限制因素,并指出了今后昆虫病原真菌研究利用中应加强的方面。

Application of Entomopathogenic Fungi in Biological Control of Agricultural and Forestry Pests

For a long time,entomopathogenic fungi has played an important role in the natural regulation of insect pests in agriculture and forestry as a kind of important biocontrol agents.The current utilization of entomopathogenic fungi resources,the pathogenesis to insect pests and the application status of main species in controlling agricultural and forestry pests were reviewed.The limiting factors in entomopathogenic fungi against to pests were analyzed,and the main area in the research and utilization of entomopathogenic fungi that require strengthening in the future were pointed out.
