Natural mortality in two filarial vectors.

Bull World Health Organ. 1963;28(2):229-34.
Little has been written about the survival of filarial mosquitos in nature, although methods are available for determining natural mortality in the field. Every filarial infection in a mosquito provides some information about the number of days it has survived after infection. This can be used to determine the probability of survival of an infected mosquito population in the field. The parous rate of the vector provides another method for estimating natural mortality. Several estimates of natural mortality in two mosquitos, Culex fatigans and Anopheles peditaeniatus, in South India have shown a daily mortality of from 14% to 24% during a season favourable for survival. Information on natural mortality can be obtained during routine dissections of mosquitos for filarial larvae, but a more positive approach to the problem of the identification of filarial infections in mosquitos is needed.
有关丝虫病蚊子在自然界中的存活情况，虽然已有方法可用于确定野外的自然死亡率，但相关文献却很少。蚊子感染丝虫后存活的天数，为其提供了有关其存活天数的信息。这可用于确定野外感染蚊子种群的存活概率。媒介的产卵率为估算自然死亡率提供了另一种方法。在印度南部，对两种蚊子（库蚊和按蚊）的自然死亡率进行了几次估算，结果表明，在有利于生存的季节，每天的死亡率为 14%至 24%。在为幼虫进行常规解剖以获取有关丝虫病的信息时，可以获得有关自然死亡率的信息，但需要采用更积极的方法来解决在蚊子中鉴定丝虫感染的问题。
