云南不同地理株微小按蚊实验室饲养观察

Rearing Observation in Laboratory on Different Geographical Strains of An.minimus from Yunnan

目的：实验室饲养繁殖微小按蚊。方法：群体及单管饲养。结果：在２５～２７℃、相对湿度７２％～８０％、每日光照１２小时的实验室条件下，各地株微小按蚊的孵化率、化蛹率和羽化率，群养分别为９０１５％、５３２４％、９７２０％，单管饲养分别为５８８２％～９８９８％、１０２０％～８６８９％、６６６７％～１００００％。成虫前期各阶段发育平均时间，群养及单管卵期均为２天，幼虫期、蛹期分别为１２～１９５天、１５８～１８５天。各地株成虫生殖营养周期平均为３５天。雌雄蚊平均寿命分别为２４２５天、１９７８天。

From 1992-1997, different geographical strains of An.minimus from Yunnan have been observed in laboratory (temperature: 25-27 degree centigrade; humidity: 72%-80%; illumination: 12h/d) by simple and colony rearing. The hatching rates of the colony, pupae rates and emergency rates were 90.15%, 53.24% and 97.20%, respectively; Those of the single 58.82%-98.90%, 10.2%-86.89% and 66.67% -100%,respectively. The average period of pre-mature stage of adult were egg: 2d, pupae: 1.58- 1.85d, larvae: 12-19.5d. The reproductive rates and the period of growth of pre-mature stage were different in these strains from different geographical zone. The average cycle of reproductive nutrition was 3.5d. The average life-span was 24.25d in female and 19.78d in male.
