Abstract

Aspergillus flavus Link., a fungal parasite on the leaf-eating caterpillar, Lymantria obfuscata Walk.

Abstract

Larvae of Lymantria obfuscata Wlk. that were observed damaging the young leaves of cacao in the Indian State of Karnataka [cf. preceding abstract] were found to increase considerably in numbers during the rainy season, but some became infected by Aspergillus flavus. This fungus produced yellowish-white patches on the body of the host, sluggishness and cessation of feeding, and later its conidiophores covered the body of the larva. A pure culture was obtained from infected insects. Over 75% of larvae either dusted with spores or provided with cacao leaves sprayed with a spore suspension became infected and died in 3-4 days. The reisolated fungus from infected larvae was found to be similar to the original culture.
