Abstract
During the course of mass breeding of Microbracon brevicornis in the parasite laboratory of the Entomology Division of this Institute for the purpose of exporting them to the United States of America for the control of pink boll worm in the cotton belt of that country, it was necessary to maintain a stock of pupae of the parasite in cold storage at a temperature of 10 ± 3° C. It was observed that the adults emerging from the chilled pupae which had been in cold storage from 10 to 75 days showed dark pigmentation ranging from dark grey to jet black, as against the distinctly brown individuals obtained from unchilled pupae.
