Anopheles populations were monitored for one year in 2 neighboring villages in Faiyum Governorate, Egypt, to study factors causing differences in malaria prevalence. Both villages contained the following species: Anopheles pharoensis, An. sergentii, An. multicolor and An. tenebrosus. Abundant larval breeding sites in Abheet, the village with the higher malaria rate, accounted for the higher adult densities observed from human and animal biting collections and from indoor resting collections. Anopheles pharoensis and An. sergentii were the dominant species in Abheet with seasonal biting activity extending from May to December, reaching a peak in November. In El Zawya, the village with the lower malaria rate, An. pharoensis dominated, reaching seasonal peaks in June and August. Inside houses, An. sergentii was common from May to January in Abheet, but rare in El Zawya. Anopheles pharoensis and An. sergentii were both incriminated as malaria vectors based upon their seasonal abundance and the finding of sporozoite positive specimens during the peak malaria season.
在埃及法尤姆省的两个相邻村庄对按蚊种群进行了为期一年的监测，以研究导致疟疾流行率差异的因素。两个村庄都有以下几种按蚊：法老按蚊、塞氏按蚊、多彩按蚊和阴暗按蚊。疟疾发病率较高的阿卜赫特村有大量幼虫滋生地，这导致从人咬和动物咬采集以及室内栖息采集观察到的成虫密度较高。法老按蚊和塞氏按蚊是阿卜赫特村的优势种，季节性叮咬活动从5月持续到12月，11月达到高峰。在疟疾发病率较低的宰维耶村，法老按蚊占主导，在6月和8月达到季节性高峰。在房屋内，塞氏按蚊在阿卜赫特村5月至1月很常见，但在宰维耶村很少见。根据法老按蚊和塞氏按蚊的季节性数量以及在疟疾高发季节发现子孢子阳性标本，二者均被认定为疟疾传播媒介。
