The feeding habits of Anopheles sacharovi under natural conditions and in feeding rooms were investigated by use of the gel diffusion technique. Mosquitoes were collected from various villages of Cukurova and also from feeding rooms especially prepared for these experiments. Human, cow, sheep, chicken, horse, and donkey were used as hosts in these rooms. The results showed that An. sacharovi is a zoophilic species. The females preferred donkey when human, cow, sheep, chicken, and horse were equally available. Their preference changed to horse, cow, and sheep in the absence of donkey. The host preference index (HPI) was always smaller than 1 for humans in habitats offering a choice of hosts. The human blood index was high only in human dwellings. In other habitats numbers of mosquitoes feeding on animals were higher than on humana. Although the human blood index was low, An. sacharovi is the principal human malaria vector in Turkey partly because a significant proportion of those resting in human dwellings have fed upon the occupants, and partly because of the uneven distribution of human and animal hosts.
利用凝胶扩散技术,对萨氏按蚊在自然条件下和饲养室内的摄食习性进行了研究。蚊子采集自库库罗瓦的各个村庄以及专门为这些实验准备的饲养室。在这些饲养室中,使用人、牛、羊、鸡、马和驴作为宿主。结果表明,萨氏按蚊是一种嗜动物血的物种。当人、牛、羊、鸡和马都同样可得时,雌蚊更喜欢驴。在没有驴的情况下,它们的偏好变为马、牛和羊。在有多种宿主可供选择的栖息地中,人类的宿主偏好指数(HPI)始终小于1。仅在人类住所中,人类血液指数较高。在其他栖息地,以动物为食的蚊子数量高于以人类为食的蚊子数量。尽管人类血液指数较低,但萨氏按蚊仍是土耳其主要的人类疟疾传播媒介,部分原因是在人类住所中休息的蚊子中有很大一部分以居住者为食,部分原因是人类和动物宿主分布不均。
