Detection of antimicrobial activity in accessory gland secretions of the virgin male red palm weevil, Rhynchophorus ferrugineus

Abstract

Background: Bioactive molecules have been identified from accessory gland secretions in insects. Antibacterial properties are identified in secretions of insect reproductive system.Study design: Antibacterial screening of male accessory reproductive gland (MARG) secretions in red palm weevil, R. ferrugineus was conducted by disc diffusion sensitivity method against eight bacterial species.Result: Accessory gland secretions showed antibacterial property as growth inhibition zones in all bacteria used in this study.Conclusion: Antimicrobial property of MARG may be evolved to protect the gametes during mating since reproductive tract is also route of microbial invasion in insects.
