Adult earthworms Eudichogaster kinneari were exposed to a safe concentration (0.5 ppm) of Azodrin for twenty days to evaluate the effect on different stages of spermatic follicles. Spermatogenesis was severely affected by exposure of above insecticide causing degeneration in tissues of spermatic follicles due to clumping, vacuolization and necrosis. Changes in histochemical reactions and significant reduction in size of spermatic follicles (p0.001) were also observed.
