来自淡水和半咸水地区的亚斑按蚊同时喂养5名志愿者，血液中含有恶性疟原虫配子体。比较两组对感染的敏感性。两个沃茨都发现了感染，但程度不同。食饵蚊虫的平均敏感率淡水区为6.1%，咸水区为17.4%。前者的平均卵囊数为3.4 +/- 3.2，后者为4.2 +/- 4.32。至摄食后第9天，淡水形式的死亡率为93.8%，微咸水形式的死亡率为90.1%。对野外捕获的雌虫进行解剖发现，两个地区的成虫寿命较短，为7-8天。尽管相当大比例的蚊子是嗜中性的，易受感染，但它们寿命短似乎是它们在这些地区传播疟疾的限制因素。(C)1998年由Elsevier Science B. V.出版，版权所有。
Anopheles subpictus from fresh and brackish water areas were fed simultaneously, on five volunteers, with Plasmodium falciparum gametocytes in their blood. The susceptibility to infection was compared. Infections were found in both waters, but to different degrees. The mean susceptibility rate among fed mosquitoes was 6.1% from the fresh water area and 17.4% from the brackish water area. The mean number of oocysts in the former was 3.4 +/- 3.2 and 4.2 +/- 4.32 in the latter. The mortality rate, up to day 9 post feeding, was 93.8% in fresh water form and 90.1% in brackish water form. Dissections of wild caught females showed that longevity of adults from both areas was shorter, 7-8 days. Despite a considerable proportion of mosquitoes being anthropophilic and susceptible to infection, their low longevity seems to be the limiting factor in their role in malaria transmission in these areas.
