摘要
羽化1～2天的中华按蚊.致倦库蚊和白纹伊蚊分别胸内接种马来丝虫微丝蚴,在接种后的第3、4、5和9天,分头、胸、腹3部解剖计算各种蚊虫体内黑化微丝蚴及发育各期幼虫。结果表明:中华按蚊、致倦库蚊和白纹伊蚊的微丝蚴黑化率分别为51·6％、86·1％和69·5％,差异显著;3种蚊虫体内的感染期幼虫率及感染期幼虫阳性率分别为35.3％、1·6％、0％和83·9％、23·5％、0％。黑化微丝蚴较多地集中在蚊虫腹部,占黑化微丝蚴总数61·6％～78·4％。
One- to two day old mosquitoes Anopheles sinensis, Culex quinquefasciatus and Aedes albopictus were thoracically inoculated with 15~20Brugia malayi microfilariae per individual. The inoculated mosquitoes subsequently were dissected into head, thorax and abdomen to count the number of melanized microfilariae other developing stages of melanized microfilariae varied with the species and related to the susceptibility of the mosquitoes to the filaria. At the same time, differences in the rate of mature larvae and the rate of infective mosquitoes were also found among the species. Most (61.6%~78.4%) of the melanized microfilariae were observed in the abdomens of mosquitoes.
