Post Mating Reduction of Proteins in the Accessory Sex Glands of Male <i>Spodoptera mauritia</i> Boisd

The accessory sex gland (ASG) secretions play a crucial role in the reproductive success of insect pests. When mated males of Spodoptera mauritia were compared to virgin males, the amount of protein in their ASG secretions was significantly lower. In the Poly acrylamide gel electrophoresis three peptides designated in virgin males as ASG 4, 7 and 15 were absent in the electrophorogram of mated males. Mated males also showed lower staining intensities for several peptides.
