Abstract
The majority of chemicals utilized in the field were insecticides, which have substantial consequences for reproduction and fitness. Proteins generated from the accessory gland cause post-mating physiological changes in mated females and have an impact on fitness in many insects. As a result, insects are an excellent model organism for studying the effects of environmental chemical contaminants like paraquat on male accessory gland and sperm characteristics.In the present investigation male diet effects on accessory gland traits and sperm has been studied in D. melanogaster. Oregon K strain of D.melanogaster raised on either control diet or paraquat treated diet were used to examined the outcome of paraquat effects on accessory gland and sperm traits to understand its effect of male reproductive success in D. melanogaster. It was noticed that male fly raised on control diet had more small main cells in their accessory gland and produced more accessory gland protein; whereas males raised on paraquat treated diet had fewer large main cells and produced much less accessory gland protein. Furthermore, males raised on a control diet copulated longer, transferred more accessory gland protein and sperm to mated females than males raised on a paraquat-treated diet. Thus paraquat treatment in D. melanogaster has a significant negative impact on accessory gland protein, sperm characteristics and male fitness.
