| 摘 要： | 八十年代以来,我区麦蚜频繁成灾,减产2—3成的麦田较为普遍,研究证明:成灾的主要原因是优势种群已由麦长管蚜Sitobion avenae(Fabr.)转变为禾谷缢管蚜Rhopalosiphumpadi(L.)。田间调查弄清了禾谷缢管蚜在不同海拔高度的早、中、晚播麦田的不同生育阶段,以及在植株各部位的分布。穗期禾谷缢管蚜发生轻重与3月中旬平均温度呈正相关,与3月下旬雨量呈负相关。由此建立了预测禾谷缢管蚜发生程度的多元回归方程式: Y=0.792 0.205X_1-0.015X_2用这个预测式回测8年田间实测值与预测值极近。

| Abstract: | Since 1980s,Wheat has been damaged seriously by cereal aphids in Sichuan.The yield of wheat was reduced by 20-30% every year.The chief reason is that the dominant specis has been turned from the English grain aphid (Sitobion avenae (Fabr.))into the birdcherry-oataphid (RhopaUiphum padi(L.)). |
