摘　　要：观测分析了大田条件下 UV- B辐射增强对麦田中麦蚜的影响 ,结果表明UV- B辐射增强 ,蚜虫发生总量、小麦植株发生的百分率显著降低 ,蚜虫在穗部和植株上部叶片的发生概率下降 ,但蚜虫在叶片背光面发生数量增多 ,小麦植株的虫害发生概率降低。Effects of enhanced ultraviolet radiation(UV B,280～315nm) on wheat aphid are investigated in this paper.Results show that the number of wheat aphids and the percentage of wheat plants attacked by aphids decrease markedly with UV B radiation,the probability of aphid's appearance on the ears and the upper leaves decreases dramatically,but the number of aphids on back side of the leaves increases significantly.It is concluded that the enhancement of UV B radiation make wheat crop less affected by the aphid.
