Abstract: Isolated pairs of Hieroglyphus nigrorepletus did not show accelerated mating behaviour like crowded pairs. Early mating suggests that an expedited secretion of certain sex hormones is. responsible for inducing early mating under stress of crowding. Insects in cages kept permanently in the open air appeared more healthy and vigorous than those kept in cages indoors. It was found that oxygen consumption in insects in open air cages was 13.3 X 10^-4 ml/s/adult, whereas in indoor cages it was 7.51 X 10^-4 ml/s/adult. There was no significant difference between crowded and isolated insects regarding oxygen consumption.
