Abstract
Hipoepa biasalis (Walker) is reported for the first time as a defoliator green semilooper of soybean in the zone. Epizootics of an entomopathogenic fungus, Nomuraea rileyi (F.) Samson was observed on all the defoliators of soybean field except S. obliqua for the first time from southern humid zone of Rajasthan. The cloudy condition coupled with high humidity has favored the growth of this fungus to infect the defoliators effectively in soybean. Initially larvae were infected with white spores then covered with the green spore mass. The prolegs were attached to the leaves while the front legs were hanging above the leaves. Most of the dead larvae were attached to the midrib of the leaves. The mean number of dead larvae was in the range of 3-4 per meter row length.
