摘要: 目的:研究中华按蚊对不同密度马来丝虫微丝蚴以及贵州和浙江两地虫源的易感性。方法:观察中华按蚊感染不同密度马来丝虫微丝蚴(mf)后蚊虫的存活率、蚊虫体内微丝蚴发育至感染期蚴(L3)率和感染蚊体内L3平均条数,同时观察浙江虫源(6代)和贵州虫源(31代),微丝蚴发育至L3率。结果:感染微丝蚴密度为32.5mf/μl和141. 5mf/μl组的微丝蚴发育至L3率分别为36.2%和8.7%,感染蚊体内L3平均条数分别为8.24和0.3条。中华按蚊感染浙江虫源(6代)和贵州虫源(31代),微丝蚴发育至L3率分别是45.1%和26.8%。结论:中华按蚊对感染密度为32.5mf/μl-66.4mf/μl时较易感,其对浙江虫源(6代)较贵州虫源(31代)易感。

Abstract: AIM: To explore the susceptibility of Anopheles sinensis to Brugia malayi microfilariae of
different densities . METHODS: The survival rate of mosquitoes,the rate of microfilariae penetrating through
midgut, the mature rate of larvae into infective larvae(L3) and the mean number of L 3 in the survived
mosquitoes were observed. RESULTS: With the microfilariae densities of 32 5 mf/μl and 141 5 mf/μl, the rate
of larvae matured into L3 was 36.2% and 8.7%, respectively, the mean number of L3 recovered from infected mosquitoes was 8.24 and 0.30, respectively. CONCLUSION: An apparently higher susceptibility of An. sinensis to
B.malayi was found by using B.malayi microfilariae density of 32.5- 66.4 m f/ul.
