Abstract

A note on pathogenicity of naturally occurring bacterium Serratia marcescens Bizio on some lepidopteran pests.

Abstract

Serratia marcescens is reported attacking larvae of the noctuid Heliothis armigera [Helicoverpa armigera] collected in Karnataka, India, in 1983. In laboratory studies, larvae of the noctuid Spodoptera litura and the pyralid Chilo partellus were also found to be susceptible to this bacterium. S. litura was more suscepible to attack than H. armigera or C. partellus. The bacterium was equally pathogenic whether administered by artificial diet or on the natural food plant, but pathogenicity by contact application on the body of the larvae was poor.
