绿僵菌Metarhizium anisopliae具有分布范围大,对昆虫寄生谱广的特点,常被用来防制多种害虫。在医学昆虫方面,在近十几年才开始研究,至今仍在不断地探索中。在蚊虫方面,Roberts(1977)和Castillo(1980)曾有过综述。Rizzo(1977)曾用体表接触法感染过家蝇,都证明有不同程度的毒力。为筛选对医学昆虫毒力较高的菌株,作者于1984年收集不同地区、不同寄主分离的14株绿僵菌,在实验室对蚊幼虫、 Metarhizium anisopliae is characterized by its large distribution range and wide parasitic spectrum of insects, and is often used to control various pests. In the field of medical insects, research has only started in the past ten years and it is still under continuous exploration. In mosquitoes, Roberts (1977) and Castillo (1980) have reviewed. Rizzo (1977) had been infected by body surface contact with housefly, have proved to varying degrees of virulence. In order to screen for strains that are more virulent to medical insects, the authors collected 14 strains of Metarhizium anisopliae from different regions and separated by different hosts in 1984. In the laboratory,
