Abstract

Adult Eudichogaster kinneari were exposed to a safe concentration (0.6 ppm) of Dimethoate for twenty days to evaluate the effects on different stages of spermatic follicles. Chronic exposure of above insecticide severely affected the spermatogenesis causing vacuolization and liquefaction of spermatic follicles, uneven arrangement of spermatozoa around the cytophore and ultimate atrophy of spermatic follicles. Size reduction of spermatic follicles (p0.001) as well as changes in histochemical reactions were also observed.
