The abundance of Anopheles arabiensis and its susceptibility to insecticides was studied in New Halfa, eastern Sudan, from March 1999 to June 2000. Of 4854 females anophelines collected, 4847 (99.9%) were An. arabiensis and 7 (0.1%) An. pharoensis. Female An. arabiensis were breeding throughout the year, with 2 peak densities, during the rainy (158.4 females/room/day and 84.7 larvae/10 dips) and irrigated seasons (136.8 females/room/day and 44.8 larvae/10 dips). The mean biting activity was 28.8 bites/person/ night, found throughout the night, mainly outdoors. Susceptibility of An. arabiensis to insecticides dichloro-diphenyl-trichloroethane (DDT), malathion and fenitrothion was 97.8%, 96.3% and 100% respectively. An. arabiensis is the sole malaria vector in the area and is perennial rather than seasonal.
1999年3月至2000年6月，在苏丹东部的新哈尔法对阿拉伯按蚊的数量及其对杀虫剂的敏感性进行了研究。在采集的4854只雌性按蚊中，4847只（99.9%）为阿拉伯按蚊，7只（0.1%）为法老按蚊。阿拉伯按蚊雌蚊全年繁殖，有两个密度高峰，分别在雨季（158.4只雌蚊/房间/天和84.7条幼虫/10次 dipping）和灌溉季节（136.8只雌蚊/房间/天和44.8条幼虫/10次 dipping）。平均叮咬活动为28.8次叮咬/人/夜，在夜间均可发现，主要在户外。阿拉伯按蚊对杀虫剂二氯二苯三氯乙烷（DDT）、马拉硫磷和杀螟硫磷的敏感性分别为97.8%、96.3%和100%。阿拉伯按蚊是该地区唯一的疟疾传播媒介，是常年性的而非季节性的。 （注：原文中“dips”可能是某种调查方法中的单位，因不明确其准确含义，此处保留英文未翻译）
