Previous studies have implicated the role of peptides/proteins in male accessory glands (MAGs), responsible for induction behavioral and reproductive changes Helicoverpa armigera females. Our several other seen MAG showed post-mating behaviors such as accelerated unreceptivity to re-mating traits. We reported peptides reduced mating receptivity, including a putative 4.9 kDa, novel peptide with various functions female post-copulatory behavior (PMR). In this study, we report detailed analysis proteins from biochemical, physiological, molecular evolutionary perspective. 5 major classes multigene family were detected after protein database searches. All found bind nucleic acids, possess signal peptides, undergo posttranslational modification by seminal fluid (SFPs). The Porphobilinogen synthetase (PBGS) was unique lepidopteran order. support observation that weight varies significantly across species, suggesting existence different target sites or faster evolution SFP. not only ensure fitness constantly evolving under postcopulatory sexual selection (PCSS), but also maintain species-specific barriers fertilization thus potentially contribute formation new species mediate conflicts between sexes.
