比较了感宽冈比亚按蚊和冈比亚按蚊感染组和未感染组的取食行为。产于肯尼亚西部的funestus。一个显着更大的百分比（81%）的恶性疟原虫感染的安。冈比亚公司雌性在实验宿主（仓鼠）上的探测率高于未感染的雌性（38%）。在那些开始探测的雌性中，感染状态对吸血的能力没有影响。恶性疟原虫（Plasmodium falciparum）感染的An.冈比亚公司与未感染的对应物（平均值= 2.4个探针，平均探针时间= 214秒）相比，更频繁地探测（平均值= 4.0）和更长的时间（平均值= 277秒）。结果为少量的一个。美联储的funestus也遵循了同样的趋势。感染的安。冈比亚公司对于雌性，子孢子密度对探针的数量或总的探测时间都没有影响。在未感染的女性，有没有不同的喂养行为之间的未经生产和生产的女性。在实验室实验中，雌性年龄对吸血行为没有影响。我们的研究结果提供了证据，自然疟疾感染修改按蚊雌性的摄食行为。
Feeding behavior was compared between infected and uninfected field-collected groups of Anopheles gambiae sensu lato and An. funestus from western Kenya. A significantly greater percentage (81%) of Plasmodium falciparum-infected An. gambiae s.l. females probed on experimental hosts (hamsters) than did uninfected females (38%). Among those females that initiated probing, there was no effect of infection status on the ability to take a bloodmeal. Plasmodium falciparum-infected An. gambiae s.l. probed more often (mean = 4.0) and for a longer time (mean = 277 sec) than did their uninfected counterparts (mean = 2.4 probes and mean probing time = 214 sec). Results for the small number of An. funestus that fed followed the same trend. Among infected An. gambiae s.l. females, there was no effect of sporozoite density on either the number of probes made or the total probing time. Among uninfected females, there was no difference in feeding behavior between nulliparous and parous females. In laboratory experiments, female age had no effect on blood-feeding behavior. Our findings provide evidence that natural malaria infection modifies the feeding behavior of Anopheles females.
