ABSTRACT

 

Adult Eudichogaster kinneari was exposed to a safe concentration (0.6 ppm) of Rogor for twenty days to evaluate the effects on different stages of oocytes. Chronic exposure of above insecticide severely affected the oogenesis causing dissolution and vacuolization of ooplasm, destruction of yolky material and nucleus, uneven cell boundary, broken and irregular nuclear membrane and ultimate atrophy of oocytes. Size reductions of the oocytes (p< 0.001) as well as changes in histochemical reactions were also observed.

 

Keywords : Eudichogaster kinneari, Histomorphology, Rogor, Ovary, Insecticide.
