补充资料:麦蚜
      昆虫纲同翅目(Homoptera)蚜科(Aphididae)。麦类蚜虫的统称。麦类的主要害虫。俗称腻虫。主要有麦长管蚜 (Macrosiphum avenae)、麦二叉蚜 (Schizaphis graminum)、麦无网长管蚜 (Acyrthosiphon dirhodum)和禾缢管蚜(Rhopalosiphum padi)4种。常混合发生,但以前两种为主。也为害莎草科的植物。麦蚜为多型性昆虫,无翅和有翅胎生雌蚜是主要蚜型。
  
  麦长管蚜无翅和有翅胎生雌蚜的成虫体长约 3毫米,长卵形,草绿至橙红色。触角比身体长,有翅型前翅中脉分3岔。腹管为体长的1/4,黑褐色,端部有网纹。麦二叉蚜体长约2毫米,卵圆形,淡绿至黄绿色。触角为体长的2/3,有翅型前翅中脉分2岔。腹管较短,淡绿色。麦蚜分布遍及世界各产麦国。在中国除麦无网长管蚜分布范围较狭外,其余均在各麦区普遍发生。麦二叉蚜通常仅发生在中国西北和华北麦区。亚洲、东非、北美以及北非、地中海地区和南美等地也有分布。两种麦蚜一年发生10余代至20代以上。麦长管蚜在产麦区多以无翅成、若蚜在麦株基部和土缝内越冬,北部产麦区多以卵越冬。长势好的麦田受害重。麦二叉蚜在麦类苗期即行为害,灌浆后迁飞。多栖息在植株下部和叶片背面。瘠薄麦田受害重。麦蚜主要以成、若蚜刺吸麦类等茎、叶和嫩穗的汁液,后期多集中在穗部为害,使麦株生长缓慢、分蘖数减少、千粒重下降。还可传带黄矮病等多种病毒病。
  
  
  麦蚜的主要天敌有瓢虫、草蛉、食虫蝽、蜘蛛、食蚜蝇、蚜茧蜂等类群。除利用天敌外,其他防治方法有:①合理调整作物布局,削弱麦蚜和黄矮病的寄主作物链;②选用抗蚜品种;③适期播种,清除田边杂草及自生麦,并可结合冬灌和早春碾压或耙耱,减少越冬虫口密度;④用农药处理麦种,田间可喷洒氧化乐果、敌敌畏、对硫磷、灭蚜松等杀虫剂。
