Popis:	Entomophaga aulicae (Hoffman in Bail) Batko (Zygomycotina: Entomophthorales) was found to cause epizootics in Spilarctia obliqua (Walker) (Arctiidae: Lepidoptera), a polyphagous pest in Manipur, India. Infected caterpillars climbed to elevated positions on plants where they hung upside down, attached by their abdominal prolegs. Infection levels reached up to 57%. The conidiophores are simple, conidia are ovoid to pyriform in shape, and the nuclei stained readily in aceto-orcein. Secondary, tertiary conidia and resting spores were also observed. No rhizoids and cystidia were found. This is the first report of E. aulicae infecting S. obliqua in Manipur.
