通过定期室内外观察的方法，研究了美国山核桃警根瘤蚜的形态特征和生物学习学特性，重点记录其虫瘿的变化过程。结果表明，警根瘤蚜越冬卵于3月末4月初开始孵化，4月上中旬为孵化盛期，10月中旬开始产生越冬卵。警根瘤蚜成虫有多个形态，由越冬卵孵化出的为干母，干母在寄主的幼叶上形成第一代虫瘿。警根瘤蚜在寄主叶片上形成虫瘿，成虫、幼虫均在虫瘿内吸食叶片汁液，严重影响了美国山核桃的生长。
通過定期室內外觀察的方法，研究瞭美國山覈桃警根瘤蚜的形態特徵和生物學習學特性，重點記錄其蟲癭的變化過程。結果錶明，警根瘤蚜越鼕卵于3月末4月初開始孵化，4月上中旬為孵化盛期，10月中旬開始產生越鼕卵。警根瘤蚜成蟲有多箇形態，由越鼕卵孵化齣的為榦母，榦母在寄主的幼葉上形成第一代蟲癭。警根瘤蚜在寄主葉片上形成蟲癭，成蟲、幼蟲均在蟲癭內吸食葉片汁液，嚴重影響瞭美國山覈桃的生長。

The morphological and biological characteristics of Phylloxera notabilis on Carya illinoensis trees were studied through regular indoor and outdoor observation and the changing process of the insect galls were emphatically recorded. The results showed that the hibernating eggs of phylloxera notabilis started hatching in late March or early April and the main hatching period was early and mid April,and the hibernating eggs were laid from mid October. The adults of phylloxera notabilis had several forms. The fundatrices hatched from the hibernating eggs formed the first generation galls on the host young leaves. Phylloxera notabilis formed galls on the host blades and both the adults and larvae sucked sap of the blades in galls,having a serious impact on the growth of Carya illinoensis trees.
