Blood meals were tested by a direct enzyme-linked immunosorbent assay (ELISA) for 424 Anopheles sergentii and for 63 An. multicolor collected in Siwa, Farafra and Bahariya oases in the Western Desert of Egypt. Both species were highly zoophilic. Human blood-feeding by An. sergentii was less common in Bahariya (2.3%) and Farafra (1.3%) than in Siwa (15.3%). A likely explanation is that large domestic animals are held at night inside houses in Bahariya and in Farafra whereas in Siwa, animals are usually housed outdoors in sheds. These patterns of An. sergentii human-feeding behavior may contribute to the persistence of low-level Plasmodium vivax transmission in Siwa in contrast to negligible or no transmission in Bahariya and Farafra.
采用直接酶联免疫吸附测定（ELISA）对在埃及西部沙漠的锡瓦、法拉夫拉和巴哈里亚绿洲采集的424只塞氏按蚊和63只多彩按蚊的血餐进行了检测。这两个物种都高度嗜动物性。塞氏按蚊吸食人血的情况在巴哈里亚（2.3%）和法拉夫拉（1.3%）比在锡瓦（15.3%）少见。一个可能的解释是，在巴哈里亚和法拉夫拉，大型家畜夜间被关在屋内，而在锡瓦，动物通常被养在户外的棚子里。塞氏按蚊这种吸食人血的行为模式可能导致了锡瓦地区间日疟原虫低水平传播的持续存在，而在巴哈里亚和法拉夫拉，传播可忽略不计或不存在。
