Bioefficacy and Infection Mechanism of Several Entomopathogenic Fungi on Crocidolomia Binotalis Zell

Bioefficacy and Infection Mechanism of Several Entomopathogenic Fungi on Crocidolomia Binotalis Zell

The role of entomogenous fungi as natural enemies for cruciferous insect pests has recently been explored and several siolates of hypomycetous fungi have been dientfiied. The ability of three entomopathogenic siolates of Beauveria bassiana (Bals). Vuill, Paecilomyces fumosoroseus (Wize) Brown and...
