对埃塞俄比亚南部疟疾高发区Sille的按蚊叮人行为和疟原虫感染率进行了调查。从2001年10月至2002年8月期间18：00至06：00进行的所有夜间登陆采集中确定了7种按蚊。优势种为阿拉伯按蚊（55.8%），其次为库斯坦按蚊（31.5%）、法罗按蚊（9.5%）、不死按蚊（2.2%）、尼氏按蚊（0.5%）、马氏按蚊（0.4%）和德氏按蚊（0.2%）。解剖A.平均经产率为73.2%。大部分的经产蚊子都是在后半夜叮咬的。用ELISA法测定疟原虫子孢子率。阿拉伯疟原虫感染率为0.5%（4/796），间日疟原虫感染率为1.76%（14/796），无混合感染。从我们的小样本的子孢子阳性，我们发现没有相关的咬行为和子孢子感染状态。(C)2005 Elsevier B.

The man-biting behavior and Plasmodium infection rates of anopheline mosquitoes were investigated in Sille, a hyperendemic malarious area in southern Ethiopia. Seven Anopheles species were identified from all night landing collections, conducted from 18:00 to 06:00 h between October 2001 and August 2002. The predominant species was Anopheles arabiensis (55.8%), followed by Anopheles coustani (31.5%), Anopheles pharoensis (9.5%), Anopheles funestus (2.2%), Anopheles nili (0.5%), Anopheles marshallii (0.4%) and Anopheles demeilloni (0.2%). Dissection of A. arabiensis showed an average parous rate of 73.2%. A large proportion of the parous mosquitoes were caught biting in the latter part of the night. Malaria sporozoite rates were determined by ELISA for A. arabiensis, with 0.5% (4/796) infective with Plasmodium falciparum and 1.76% (14/796) with Plasmodium vivax; there were no mixed infections. From our small sample of sporozoite positives we found no association between biting behavior and sporozoite infection status. (C) 2005 Elsevier B.V. All rights reserved.
