冈比亚按蚊和安按蚊的生态、种群动态和疟疾媒介效率。在塞内加尔萨赫勒地区的一个村庄对arabiensis进行了2年的研究。以人为饵捕获按蚊，并在室内喷洒除虫菊。蚊子属于安蚊。采用聚合酶链反应对冈比亚菌络合物进行鉴定。在26973名女性中，安。arabiensis占捕获蚊子总数的79%，并且在研究区域停留的时间比An长。冈比亚雨停后。在夜间咬食周期和自噬率方面，两组间无显著差异。冈比亚和安哥拉。arabiensis。根据血餐酶联免疫吸附试验，在同一时期进行比较时，这两种载体的亲人率均接近60%。总的来说，18%的休息的雌性有明显的混合血餐，主要是人牛。An的宇称率。冈比亚和安哥拉。Arabiensis在时间上有变化。尽管有相似的行为，恶性疟原虫环孢子子蛋白（CSP）率在安、安之间存在差异。冈比亚（4.1%）；arabiensis(1.3%)。疟疾疟原虫和卵形疟原虫仅占蚊子体内发现的疟原虫总数的4%。传播是季节性的，主要发生在4个月内。CSP昆虫学接种率为每人每年128次，第一年为100次，第二年为100次。Arabiensis占传播的63%。两组间CSP率差异的可能来源。冈比亚和安哥拉。本文讨论了阿拉伯种与胎次率、取血频率和遗传因素假说的关系。
The ecology, population dynamics, and malaria vector efficiency of Anopheles gambiae and An. arabiensis were studied for 2 yr in a Sahelian village of Senegal. Anophelines were captured at human bait and resting indoors by pyrethrum spray. Mosquitoes belonging to the An. gambiae complex were identified by polymerase chain reaction. Of 26,973 females, An. arabiensis represented 79% of the mosquitoes captured and remained in the study area longer than An. gambiae after the rains terminated. There were no differences in nocturnal biting cycles or endophagous rates between An. gambiae and An. arabiensis. Based on an enzyme-linked immunosorbent assay test of bloodmeals, the anthropophilic rate of these 2 vectors were both approximate to 60%, when comparisons were made during the same period. Overall, 18% of the resting females had patent mixed bloodmeals, mainly human-bovine. The parity rates of An. gambiae and An. arabiensis varied temporally. Despite similar behavior, the Plasmodium falciparum circumsporozoite protein (CSP) rates were different between An. gambiae (4.1%) and An. arabiensis (1.3%). P. malariae and P. ovale only represented 4% of the total Plasmodium identified in mosquitoes. Transmission was seasonal, occurring mainly during 4 mo. The CSP entomological inoculation rates were 128 bites per human per year for the 1st yr and 100 for the 2nd yr. Because of the combination of a high human biting rate and a low CSP rate, An. arabiensis accounted for 63% of transmission. Possible origin of differences in CSP rate between An. gambiae and An. arabiensis is discussed in relation to the parity rate, blood feeding frequency and the hypothesis of genetic factors.
