Abstract

Promising entomopathogenic fungi of sweet sorghum-infesting lepidopterans, namely, Helicoverpa armigera, Ostrinia furnacalis, and Spodoptera litura were reported. Novel entomopathogenic fungi identified as Metarhizium flavoviride var. flavoviridae P2A was isolated and purified from field-collected H. armigera. The LC₅₀ of M. flavoviride var. flavoviride P2A against 7-day old H. armigera larva was 4.184 x 10⁵ OBS/ml. On the other hand, a Beauveria bassiana Bb101 strain was found to cause high mortality to S. litura and O. furnacalis larvae. M. flavoviride var. flavoviride P2A and B. bassiana Bb101 are entomopathogenic fungi that can be used as biological control agents in integrated pest management program for sweet sorghum.
