ABSTRACT
Studies on various aspects of the biology of Dirhinus pachycerus, a pupal parasitoid of house flies in the Indian sub-continent are presented. The aspects dealt with include mating and insemination, oviposition and host-feeding, daily rate of oviposition, fecundity, sex-ratio, ovigenic cycle, adult nutrition and longevity. Possibilities of utilizing this parasitoid in integrated house fly control programs are discussed.
