摘　　要：[目的]研究物理因子对茶蚜种群数量消长的影响.[方法]以茶二叉蚜为材料,进行试验,就环境因素中的温度、光照、湿度以及黄板对茶蚜种群数量消长的影响进行了研究.[结果]研究结果表明,大多数荼蚜的适宜生长温度在15～25℃,温度高于28℃时,对其生长发育有抑制;光照时间为8h,死亡率最高;茶蚜一般在相对湿度50％～85％时生长发育较适宜,相对湿度高于90％或者低于40％时,对茶蚜有抑制作用;黄板有诱杀有翅成蚜的效果,并且一定高度内,诱蚜效果随高度的增加而增加.[结论]研究结果为荼蚜的综合治理提供了参考依据.[Objective]The aim was to study on effects of physical factors on population dynamics of tea aphid. [Method] Taking Toxoptera aurantii Fonscolombe as materials, the effects of environmental factors （temperature, light, humidity and yellow plate）on popula- tion dynamics of tea aphid were explored by experiment. [Result] The results showed that most tea aphids optimum growth temperature at 15-25~C, and the- ir growth and development were inhibit- ed when the temperature was higher than 28~C. The mortality rate was the highest when the illumination time was 8 h. The growth was more appropriate generally at a relative humidity of 50%-85%, and the growth was inhibited when the rela- tive humidity above 90% or below 40%. Yellow plate could lure and kill winged adult aphid, and within a certain height, the lure aphids effect increased with height. [Conclusion] The results provided references for the comprehensive man- agement of the tea aphid.
