Beauveria bassiana (Balsamo) Vuillemin - a Promising Microbial Control Agent of the Satin Moth (Lepidoptera: Lymantriidae)

A new isolate of the entomopathogenic fungus, Beauveria bassiana , was tested by laboratory bioassays for potential use as a microbial control agent of the early (third) and last (seventh) instars of the satin moth, Leucoma salicis L. Results demonstrate that this fungus is very effective against last instars of this lepidopteran pest. Although B. bassiana was cultured successfully from internal contents of all cadavers examined, vegetative hyphae emerged from intact cadavers of L. salicis infected as early (third) instar caterpillars only.
