摘　　要：目的研究不同温度下白纹伊蚊的生存时间,为预测其种群动态和扩散能力提供数据支持。方法以26℃生存的白纹伊蚊作为对照,以5℃为梯度,分别设置(11±1)、(16±1)、(21±1)、(26±1)、(31±1)和(36±1)℃6个温度梯度,记录白纹伊蚊成蚊的日生存情况;采用两独立样本t检验进行两组差异性比较,单因素方差分析进行多组单因素差异性比较,析因分析进行多因素比较;同时绘制生存曲线,比较不同温度下雌雄蚊生存率差异。结果在11~36℃时,蚊虫存活时间呈先上升后下降趋势,在16℃时生存时间最长,平均生存时间为(49.82±17.83)d,最长达80 d,在36℃(较高温)下生存时间最短,平均生存时间为(8.61±5.02)d,蚊虫在20 d内全部死亡;相同温度和时间下,雌蚊生存时间明显高于雄蚊,差异有统计学意义(F=37.261,P<0.05);雌蚊的生存率均高于雄蚊,尤其在11和26℃时;不同温度与蚊虫性别间存在交互作用(F=2.772,P=0.017)。结论 16℃下白纹伊蚊生存时间较长,温度较高或较低均不利于其生存,尤其是极端温度;不同温度下白纹伊蚊雌蚊生存时间均优于雄蚊。and to provide evidence in predicting the population dynamics and the spread of Ae. albopictus. Methods The Ae. albopictus at 26℃ was used as the control, with a gradient of 5℃. Six groups of adult mosquitoes were reared under ambient temperatures of （11±1）, （16±1）, （21±1）, （26±1）, （31±1）, and （36±1）℃, respectively. The dead mosquitoes in each replicate were counted and sexed twice every day until all the mosquitoes died off naturally. The survival analysis was employed to compare the difference of survival times among the groups. Results Under 11-36℃, the survival time of mosquitoes increased first and then decreased. Mosquitoes under 16℃ survived the longest, with average of （49.82±17.83） d and maximum of 80 d. All the mosquitoes died off within 20 d with an average of 8.61±5.02 at the temperature of 36℃ （the higher temperature）. Moreover, female mosquitoes survived longer than males for all groups, especially for those at 11℃ and 26℃ （F=37.261, P〈0.05）. Interactions between the ambient temperatures and the sex can be identified in this study （F=2.772, P=0.017）. Conclusion The survival time of Ae. albopictus lived at 16℃ was longer, and the higher or lower temperature was not conducive to its survival, especially under extreme temperatures. Moreover, females lived longer than did males.
