摘　　要：用竹筒诱捕、等间距取样方法对白纹伊蚊成蚊前期季节消长作了近一年的调查，并进一步对成蚊前期死亡率作研究。南昌市区白纹伊蚊成蚊前期始见于晚春，７、８月为密度高峰，１２月消失。成蚊前期经历了高达９５．６％的总死亡率，死亡主要发生在晚期Ⅳ龄幼虫之前的龄期与时段内。对种群消长与气象因素的关系作了分析，并对新引入的变量相对降雨日进行了讨论。Nearly one year survey on population fluctuation of preadult Aedes albopictus was conducted with banboo section traps and equal interval sampling method.Based on the field-collected data,a time specific life table was constructed.The results indicated that in Nanchang city,the preadult population first appeared in the late spring,reached its peak density in July and August,and disappeared in December.The preadults experienced a total mortality of 95.6% and main deaths took place befor the late 4th instar.Relationship between some meteorological factors and population density was analysed,and a newly introduced variable,the relative rainfall day was discussed.
