Monophenol oxidase (MPO) and diphenol oxidase (DPO) activity in hemocytes and cell-free plasma perfused from 7-, 14-, 21-, and 28-day-old Aedes aegypti mosquitoes were compared. A progressive decrease of enzyme activity was detected as mosquito age increased, and this decrease was significant in both hemocytes and cell-free plasma when mosquitoes were 28 days old as compared with that found in 7-day-old mosquitoes. There was no significant difference in total hemolymph protein as mosquito age increased. Although this decreased MPO and DPO activity might be partially responsible for the reduced immune response against filarial worms previously reported for older mosquitoes, other factors undoubtedly play a significant role.
比较了7日龄、14日龄、21日龄和28日龄埃及伊蚊血细胞和无细胞血浆中的单酚氧化酶（MPO）和二酚氧化酶（DPO）活性。随着蚊子年龄的增加，酶活性逐渐降低，与7日龄蚊子相比，28日龄蚊子的血细胞和无细胞血浆中的这种降低均具有显著性。随着蚊子年龄的增加，血淋巴总蛋白没有显著差异。虽然MPO和DPO活性的降低可能部分导致了先前报道的老年蚊子对丝虫免疫反应的降低，但其他因素无疑也起着重要作用。
