Abstract

The seasonal incidence and biology of plume moth, Sphenarches caffer infesting bottle gourd was studied in Varanasi, Uttar Pradesh. The incidence of plume moth started from May and reached its peak during the first week of August. A solitary, larval endoparasitoid, Apanteles paludicole Cameron (Braconidae) was found to co-exist with this pest almost from beginning with peak parasitization of 40.91%. Among the biotic factors, higher parasitization by this endoparasitoid and relatively lower temperature amongst the abiotic parameters from November onwards might be responsible for the minor pest status of S. caffer on bottle gourd in this region.
