摘要: 在实验室条件下,对淡色库蚊进行了生物学的观察研究,得出该蚊的生殖营养周期为6.7天,平均每块卵筏含卵94.2粒,卵的孵化率、幼虫及蛹的存活率均高达90%以上;成蚊平均寿命为27天,羽化后第2天即可交配,5天后受精率达50%以上;1只雄蚊可与多只雌蚊有效交配,但在小空间范围内则不易交配;平均每蚊产卵341.07粒,净增殖率为170.5303.内禀增长率为0.1995;30天内种群增殖高达400倍,生命力?繁殖力极其旺盛?根据结果,对该蚊种群传播丝虫病和防治措施加以讨论。

Abstract: Laboratory studies on the bionomics of Culex pipiens pallens indicated that the mosquito's ponotrophic cycle was 6.7 dayS and its egg-raft had 94.2 eggs on the average. The egg-hatching rate and the survival rate of larvae and pupae reach more than 90%. The adult's average life span is about 27 days.The mosqu ito can mate on the second day after emergence and the fertilization rate can reach more than 50% after five days of its emergence.One male cna mate successfully with several females,but can't do in small space. The number of eggs which one female produces on the average is 341.07, net reproductive rate is 170.5703 and innate capacity of population increase is 0.1995. The population of the mosquito would increase almost by 400 folds in about 30 days. So the mosquito has great vitality and fecundity.These results are discussed in the context of filariasis transmission.
