中文摘要:为明确气候变暖对不同纬度带麦田麦长管蚜Sitobion avenae和禾谷缢管蚜Rhopalosiphum padi种群动态的影响，在高纬度的河北省廊坊市（39°30'N，116°36'E）和相对低纬度的河南省原阳县（34°55'N，114°15'E）开展红外线辐射增温试验，调查廊坊市（+2.00℃）和原阳县（+1.18℃）2个试验点的增温处理小区和对照小区麦长管蚜和禾谷缢管蚜的种群动态，并计算其盛期发生比值。结果表明，增温使廊坊市试验点的麦长管蚜始见期、峰期分别提前21、7 d，使原阳县试验点的麦长管蚜始见期、峰期分别提前14、14 d；而禾谷缢管蚜的始见期和峰期仅在原阳县试验点提前31 d和7 d。增温使廊坊市试验点的麦长管蚜盛期蚜量、峰期蚜量分别显著增加了139.21%和77.83%，禾谷缢管蚜盛期蚜量和峰期蚜量分别显著增加了157.31%和130.16%；增温使原阳县试验点的麦长管蚜盛期蚜量、峰期蚜量分别显著增加了149.62%和176.52%，禾谷缢管蚜/麦长管蚜的盛期蚜量比值显著降低了43.21%。表明增温有利于高纬度地区（廊坊市）麦长管蚜和禾谷缢管蚜种群增长，而在低纬度地区（原阳县）仅有利于麦长管蚜种群增长。

Abstract:In order to understand the impact of global warming on the population dynamics of the wheat aphids, Sitobion avenae and Rhopalosiphum padi, in wheat fields across different latitudes, the field experiments of temperature-elevation (Te) with infrared radiator heating device were conducted at two latitudes:Langfang City (39°30'N, 116°36'E), Hebei Province and Yuanyang County (34°55'N, 114°15'E), Henan Province. The population dynamics of S. avenae and R. padi were investigated in the two tested areas with Te treatment (+2.00℃) and control in Langfang, and Te treatment (+1.18℃) and control in Yuanyang, and the ratio value of two aphid populations was calculated during the peak stage. The results showed that, for S. avenae, warming advanced the initial appearance and peak period by 21 d, 7 d in Langfang, and 14 d, 14 d in Yuanyang, respectively, but for R. padi, the advancement (by 31 d, 7 d) only occurred in Yuanyang. Warming significantly increased the abundance of S. avenae at peak stage and the peak values were increased by 139.21%, 77.83% in Langfang and 149.62%, 176.52% in Yuanyang, respectively; R. padi increased by 157.31%, 130.16% only in Langfang, but the ratio value of R. padi to S. avenae was significantly decreased by 43.21% in Yuanyang. The results indicated that warming benefited both aphid populations at the relative higher latitude like Langfang, but only benefited S. avenae population at the relative lower latitude like Yuanyang.
