摘要： We analysed three isoenzyrme patterns of esterase(Est),lactate dehydrogenase(LDH)and per-oxidase(POD)between An.sinensin(A.s.)and An.anthropophagus(A.a.)by polyacrylamide gelelectrophoresis(PAGE). Fresh female mosquitoes were collected on emergence from Northern part of Fujian.and were in-dividually ground in homogenate buffer and centrifuged at 3000 rpm for ten minutes.All of supernat-ant fluid for each sample was used for electrophoresis in 7.5％ separate gel,pH88.9,and 2.5％
