Beauveria bassiana (BALSAMO) Vuillemin (Hyphomycetes)
is one of the most extensively studied entomopathogenic
fungal species and is the active agent in
many entomopathogenic products currently in use or
under development worldwide (Butt et al. 2001, Inglis
et al. 2001). Beauveria bassiana is a potentially useful
control agent for suppressing the population levels of
several economically important insect species. Pest
species that have been evaluated include sweet potato
whiteßy Bemisia tabaci (Gennadius) (Wright 1992,
Carruthers et al.1993), Colorado potato beetle Leptinotarsa
decemlineata (Say) (Poprawski et al.1997),
European corn borer Ostrinia nubilalis (Hubner)
(Lewis et al. 1996), migratory grasshopper Melanoplus
sanguinipes (Fab.) (Marcandier and Khachatourians
1987), and a variety of other insect pests of Þeld crops
(Feng et al. 1994)
