新个体的不断招募使得难以研究多化性蚊子的生存情况以及疟疾病媒自然种群中的传染性水库的规模。在坦桑尼亚一个村庄，通过每日灯光诱捕对冈比亚按蚊Giles sensu种群进行长期监测期间，一段短暂的干旱期导致招募停止33天，A.巴顿在一个哨舍里从2000多只抓到不到10只。放置在村里其他地方的陷阱也显示出类似的比例下降，尽管捕获的数量因地点而异。根据种群下降率估计，每天的存活率为83%。存活率与蚊子的大小无关。据估计，每次喂食的传染性储库（蚊子获得感染的机会）为2%。利用偶然事件暂时消除生活史中的一个阶段，在多化性昆虫的生物学研究中具有普遍适用性。
The continual recruitment of new individuals makes it difficult to study both the survival of multivoltine mosquitoes, and the size of the infectious reservoir in natural populations of malaria vectors. During long-term surveillance of a population of Anopheles gambiae Giles sensu late in a Tanzanian village by daily light trapping, a temporary dry spell resulted in the cessation of recruitment for a period of 33 days, and a decline in numbers of A. arabiensis Patton caught from over 2000 to less than 10 in a sentinel house. Traps placed elsewhere in the village indicated similar proportionate declines although numbers caught varied according to location. A survival rate of 83% per day was estimated from the rate of population decline. Survival was unrelated to the size of the mosquitoes. The infectious reservoir (the chance of a mosquito acquiring an infection) was estimated to be 2% per feed. The exploitation of fortuitous events which temporarily eliminate a single stage in the life cycle has general applicability in the study of the bionomics of multivoltine insects.
