摘要：德国小蠊是一种全球性分布的卫生害虫，它们的活动给人类健康造成较大的影响。常用的德国小蠊防治药剂主要是化学农药，但已经产生较强的抗药性，这使得我们求助于生物农药。昆虫病原真菌就是一类比较重要的生物农药，国内外已有一些关于利用病原真菌防制德国小蠊的报道，但由于德国小蠊体内存在抗菌肽、共生真菌、细菌等，使得其自身的免疫能力较强。该文主要是针对昆虫病原真菌防制德国小蠊的种类、传播、侵染和致病机制的研究进展做一综述，讨论昆虫病原菌防制德国小蠊的未来研究方向，旨在为德国小蠊可持续治理提供科学依据。

Abstract:German cockroach,Blattella germanica, a globally distributed sanitary pest, has become a big threat to humanhealth. The commonly used pesticides againstB. germanicaare chemicals pesticides. However, the fact thatB. germanicahas developed resistance to such chemical pesticides turns our eyes to biopesticides. Entomogenous fungi are just animportant type of such biopesticides. The anti ?B. germanicaactivity of entomogenous fungi has already been studied.However, due to the existence of antibacterial peptides and endosymbionts,B. germanicashows great immunity toentomogenous fungi. In this paper, we review research advances in the species, propagation, infection, and pathogenicmechanism of entomogenous fungi for controllingB. germanicaand discuss its future direction, with the purpose ofproviding a scientific basis for sustainable management ofB. germanica.

Key words: Blattella germanica; Entomogenous fungus; Route of transmission; Pathogenic mechanism
