| 摘 要： | 本研究分析了麦蚜及其天敌生态位的概貌．结果表明两种麦蚜以黍缢管蚜生态位宽度较广（B=0．7284）；麦长管蚜生态位宽度较窄(B=0．6264)；麦长管蚜与黍缢管蚜存在生态位重叠（L=0．6497）．在天敌群落中生态位宽度依次为食蚜蝇>飘虫>蚜茧蜂>蜘蛛>食虫蝽。天敌之间亦存在生态位重叠．五类天敌与麦长管蚜的生态位重叠均值高于与黍缢管蚜的均值．即天敌对麦长管蚜的空间跟随，控制作用越大．

| Abstract: | The niche of two wheat aphids and their natural cnemies was studied in this paper.The resultsshowed that the niche breadth of Rhopalosiphum padi L. was wide(0.7284)and the niche breadth ofMacrosiphum avenae Fabricius was narrow(0.6264).In natrual enemy community,the niche breadth was inapproximately decreasing order from hover fly to ladybird beetle,aphid parasite,spider and insectivorousbug.The niche overlap value between the five species of natural enemies and Macrosiphum avenae Fabriciuswas bigger than the five species of natural enemies and Rhopalosiphum padi L. The niche overiap aiso exitedamong the five natural enemies.The following phenomenon and control effect of the five natural enemies toMacrosiphum avenae Fabricius was better than those to Rhopalosiphum padi L. |
