阿拉伯按蚊是赞比亚马查恶性疟原虫传播的主要媒介。由于经过杀虫剂处理的蚊帐 (ITN) 有可能改变宿主的摄食行为，因此在引入 ITN 后的两个雨季期间对媒介的嗜兽性和外食倾向程度进行了评估。疾病控制中心的光陷阱、配对的室内/室外人类着陆捕获物和室外牛诱饵收集被用来评估宿主偏好的潜在变化。结果支持 An 的假设。尽管大量使用驱虫蚊帐，但马查的阿拉伯蚊子仍然高度嗜人性。马查的阿拉伯按蚊似乎具有相对的外食性，并且被发现在日落后和日出前立即在户外叮咬，这可能会规避杀虫剂蚊帐的一些保护作用。
Anopheles arabiensis mosquitoes are the primary vector responsible for Plasmodium falciparum transmission in Macha, Zambia. Because insecticide-treated bed nets (ITNs) have the potential to alter host feeding behavior, the extent of the zoophilic and exophagic tendencies of the vector was evaluated during the two rainy seasons after ITN introduction. Centers for Disease Control light traps, paired indoor/outdoor human landing catches, and outdoor cattle-baited collections were used to assess potential changes in host preference. Results support the hypothesis that An. arabiensis mosquitoes in Macha remain highly anthropophilic despite high ITN use. Anopheles arabiensis mosquitoes in Macha appear to be relatively exophagic and have been caught biting outdoors immediately after sunset and before sunrise, potentially circumventing some of the protective effects of ITNs.
