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

[摘要]  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 symptomswere 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 andnucleus were observed. The possiblesignificance of these changes are discussed
