Anopheline mosquito populations were studied during 1992 in seven villages south of Bagamoyo, coastal Tanzania, prior to malaria control intervention using insecticide treated bednets. To collect mosquitoes, CDC light traps were used in ten houses per village fortnightly for 12 months. Anopheles females were identified and checked by ELISA for the presence of malaria sporozoite antigen and source of bloodmeal. An.funestus peaked in June-July after the long rains. Three members of the An.gambiae complex had different seasonality: An.arabiensis, An.gambiae and small numbers of An.merus were collected. In most villages transmission was extremely high and perennial with the entomological inoculation rate reaching three to eleven infective bites per person per night in July and persisting at around 0.1 and 1 for most of the remainder of the year. Sporozoite infection rates within the An.gambiae complex ranged from 2% to 25%, with the peaks in January and July following the two rainy periods. An.funestus showed a similar pattern. The light traps were reliable, simple to operate, and proved to be satisfactory to study the mosquito vector population.
1992年,在坦桑尼亚沿海巴加莫约以南的7个村庄,于使用杀虫剂处理过的蚊帐进行疟疾控制干预之前,对按蚊种群进行了研究。为了收集蚊子,每个村庄每两周在10所房屋中使用疾控中心(CDC)诱蚊灯,持续12个月。对按蚊雌蚊进行鉴定,并通过酶联免疫吸附测定(ELISA)检查是否存在疟原虫抗原以及血餐来源。嗜人按蚊在长雨季过后的6 - 7月达到高峰。冈比亚按蚊复合体的三个成员具有不同的季节性:收集到了阿拉伯按蚊、冈比亚按蚊以及少量的默氏按蚊。在大多数村庄,传播极为高发且常年存在,7月的昆虫接种率达到每人每晚3至11次感染性叮咬,一年中其余大部分时间持续在0.1至1左右。冈比亚按蚊复合体中的子孢子感染率在2%至25%之间,在两个雨季之后的1月和7月出现高峰。嗜人按蚊呈现出类似的模式。诱蚊灯可靠、操作简单,并且被证明用于研究蚊媒种群是令人满意的。
