Topical Infection of Cordyceps militaris in Silkworm Larvae Through the Cuticle has Lower Infectivity Compared to Beauveria bassiana and Metarhizium anisopliae.

Topical infection of entomopathogenic fungi in insects occurs when the fungal conidia attach to the insect's surface (cuticle), germinate, and then form appressoria that penetrate the cuticle and enter their bodies. In this study, we inoculated silkworm larvae with three entomopathogenic fungi, Cordyceps militaris, Beauveria bassiana, and Metarhizium anisopliae, and investigated their mechanisms of infection. Attachment of the conidia of the three entomopathogenic fungi to the surface of silkworm larvae was observed under a microscope.

Changes of the gene expression in silkworm larvae and Cordyceps militaris at late stages of the pathogenesis.

Cordyceps militaris is an entomopathogenic fungus that forms its fruiting body. The gene expression change in C. militaris and silkworm larvae were analyzed using RNA-seq to investigate the relationship of C.

Effects of Cordycepin in during Its Infection to Silkworm Larvae.

produces cordycepin, a secondary metabolite that exhibits numerous bioactive properties. However, cordycepin pharmacology in vivo is not yet understood. In this study, the roles of cordycepin in during its infection were investigated.
