Fluctuations in the adult Ae. aegypti and Ae. albopictus populations and their relationship to rainfall were studied by weekly collections from a number of stations in the city. Aedes aegypti populations generally fluctuated with the rainfall, with multiple peaks, except in the middle of the year when there was no increase in rainfall at the time of the peak in population. It is suggested that other regulating factors, in addition to rainfall, also determine the fluctuations of this species. Aedes albopictus also fluctuated, with three peaks in a year, and these bore a close relationship to rainfall.In one area, both larvae and adults of Ae. albopictus were studied simultaneously. The larval populations were investigated by exposing tin cans in the field. The population peaks of larvae were found to precede those of adults by almost exactly 2 months. It is suggested that each adult population peak represents the cumulative effect of more than one generation of mosquitos.
通过对城市中多个站点进行每周一次的采集,研究了成年埃及伊蚊和白纹伊蚊种群的波动情况及其与降雨的关系。埃及伊蚊种群通常随降雨而波动,有多个峰值,但在年中种群数量达到峰值时降雨量并未增加。这表明,除降雨外,其他调节因素也决定了该物种的波动。白纹伊蚊也有波动,一年有三个峰值,且这些峰值与降雨密切相关。在一个地区,同时对白纹伊蚊的幼虫和成虫进行了研究。通过在野外放置锡罐来调查幼虫种群。发现幼虫种群的峰值几乎比成虫种群的峰值提前整整2个月出现。有人认为,每个成虫种群的峰值代表了不止一代蚊子的累积效应。
