Abstract: A pathogen was isolated from natural dead insect of Leucania separata. It produced aubergine pigment. According to its physiological and biochemical properties, it was identified as Serratia marcescens HBZBS-1. Its serotype was O-6. The preliminary bioassay showed that this strain exhibited potent larvicidal toxicity against Oedaleus infernalis Saussure. The mortality was above 80% for 4 d after infection.
