摘要：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.
