The effect of methoprene on total hemocyte counts and histopathology of hemocytes in Papilio demoleus L. (Lepidoptera)

Abstract : The Juvenile hormone analogue (JHA) methoprene (ZR-515) was employed for its effects on total hemocyte counts (THC) and pathological symptoms in Papilio demoleus L. The results show that the low dose (1µg/µL acetone) effects cause THC reduction in general and of PLs, ADs and SPs in Particular. The hitspathological symptoms were observed as changes in PLs form. However, the high dose (100µg/µL acetone) produced imperfect and perfect supernumerary larval instars whose THC declined considerably. Extreme pathological symptoms in cell membrane, cytoplasm and nucleus were observed. The possible significance of these changes are discussed
