Laboratory risk assessment of Beauveria bassiana AAD16 on two species of ladybird beetle.

ABSTRACT: Beauveria bassiana AAD16, isolated from Allomyrina dichotoma, shows promise as a mycoinsecticide against various coleopterans. However, assessing non-target impacts on beneficial beetles like ladybirds is crucial before commercialization. Here we assessed the compatibility between ladybird beetles and B. bassiana AAD16. The virulence of the AAD16 strain was compared with that of an available commercial strain, B. bassiana GHA, for two developmental stages (adults and 3rd instar larvae) of two coccinellids, Harmonia axyridis Pallas and Chilocorus spp. Say using the topical (1μl) application method. The ST50 for the two life stages of the two ladybird beetles were not different between the two tested fungal strains. Mycosis rates recorded from the dead bodies were also not significant except
