Abstract

Pathogenicity of Isaria fumosorosae, Metrhizium anisopliae and Beauveria bassiana was checked against the adults and pupae of Bactrocera cucurbitae under lab condition. Results showed that pupal mortality by immersion of pupae into the fugal suspension was minimum as compared to the adults emerged from the treated pupae. Average mortality of pupae was ranged from 22 to 51% while adult mortality was 48.5 to 84.4% respectively. Mycelium growth rate on the dead pupae and adults was maximum in I. fumosorosae and B. bassiana while M. anisopliae treated pupae and adults showed no mycelium growth on the dead pupae and adults. This study showed that I. fumosorosae and B. bassiana were significantly effective for the control of immature as well as adults of B. cucurbitae and could be used in the field conditions by following the proper methodology.
