The present research paper provides detailed morphology and morphometrics of an anthocorid predator, Blaptostethus pallescens Poppius. To identify the alternate laboratory host to be utilized for mass production, biological parameters of the anthocorid were evaluated by rearing on UV irradiated eggs of two alternate laboratory hosts, Corcyra cephalonica (Stainton) and Sitotroga cerealella (Motsch.). Five nymphal instars were recorded on both hosts. No significant differences were observed in incubation period, nymphal duration, total developmental period and sex ratio when reared on the two hosts. However, significant differences were observed in two biological parameters i.e., adult longevity and fecundity. Longer life span and higher fecundity of B. pallescens was recorded when reared on C. cephalonica eggs in comparison to S. cerealella eggs, indicating the suitability of C. cephalonica eggs for mass rearing B. pallescens in the laboratory. B. pallescens could be reared continuously for 7 generations on C. cephalonica eggs.
