Abstract

Indiscriminate use of pesticides for the eradication of pests causes tremendous changes to the environment and also to other nontarget organisms. To prevent such contamination of the environment and save nontarget species, zoopesticides are increasingly used as they are cost effective, eco-friendly, safe, and sustainable in the field of agriculture. The present study was undertaken to find out the effect of pygidial secretion (zoopesticide) on Odontopus varicornis. The insects were exposed to pygidial secretion for 24, 48, 72, and 96 hours and its sublethal concentration was found to be about 2.8% for 48 hours. When the insects were injected with sublethal concentration 2.8% for 48 hours, the study revealed certain remarkable changes in the histopathology of the male accessory reproductive glands (MARGs) such as disintegration of epithelial cell wall, swollen nucleus, vacuolization of cytoplasm, highly pycnotic and necrotic epithelium, enlargement of epithelial cells, and disorganized tissues. It is suggested that zoopesticide causes several histopathological damages in the MARGs of O. varicornis and affects the reproductive potentiality of O. varicornis.
