Studies on the impact of defence secretion of Pheropsophus hilaris on histological changes in the testis of adult male Laccotrephes ruber (Heteroptera: Nepidae)


G Raja Selvi, T Ramesh kumar

Pesticide is used to those chemicals, which poison and control the animal and plant species. Many chemicals are used to reduce the population of insects or to prevent their attack. The pesticides are used for the eradication of pest causes tremendous changes to the environment and also to other non – target organisms. To prevent such contamination of the environment and pests, use of zoopesticides are in current use. The male reproductive system of Laccotrephes ruber consists of a pair of testes, vas deferentia, MARGs, seminal vesicle and common ejaculatory duct. The testes showed some remarkable changes in the insects treated with zoopesticide, defence secretion (13:40 ppm for 48hrs median lethal concentration). The testes of treated insects showed the presence of a ruptured testicular follicle, disintegrated speematacytes, pycnotic and necrotic speematidls.
