摘　　要：苹果根爪绵蚜是在苹果树根梢为害的重要新害虫 ,梨九绵蚜和榆绵蚜是在梨树根梢为害的重要新害虫。 6～ 9月份 ,这 3种绵蚜为害果树根部。根据防治试验、示范结果 ,春季在绵蚜迁入之前 ,采用果园全田覆盖地膜的办法 ,可阻隔其入土 ,进而可使果树根部全年免受其为害 ;夏季在绵蚜为害期 ,采用磷化铝地下熏蒸的办法 。Aphidounguis pomiradicicola Zhang et Hu, infesting the small roots of apple tree, Malus spp. Siciunguis novena Zhang et Hu and Eriosoma lanuginosum dilanuginosum (Zhang),infesting the small root of pear tree, Pyrus spp.,are all new pests discovered in recent years in Qianxian county,Shaanxi.Their damages can be found from June to September each year.The wholly aphids were prevented from entering the underground and infesting the small roots of the fruit trees if the ground surface was covered with the plastic film before the wholly aphids immigranted into the orchard in spring. The effective control measure was the Aluminium Phosphide was given into the soil to fumigate kill the aphids.
