Abstract

Competition and survival between the egg parasite Trichogramma achaeae Nagaraja and Nagarkatti and the egg-larval parasite Chelonus blackburni Cameron was studied in the laboratory on the eggs of Corcyra cephalonica Stainton. Considering the short life cycle, rapid development and feeding in its larval stage. T. achaeaee was found to compete and develop successfully irrespective of its initial or later parasitization.
