         一般影响

    C. cupressi柏蚜吸食树枝的汁液,会造成叶子的黄化。根据受感染的时间长短及伤害程度,危害可从部份枝条枯萎到整棵树的死亡。(O'Neil, 1998) 皇家园艺协会(2004)列出柏蚜感染的症状:夏天时新芽会黄化; 到了夏末这些枝条会变褐色而死亡。被修剪的树篱枯萎的情况更明显,而低的部位比顶端感染的情况更严重; 受感染的枝条、叶子会慢慢被煤烟病所形成之黑色的粉末所覆盖。

    Watson et al. (1999)记录柏蚜在非洲、意大利、约旦、也门、模里西斯及哥伦比亚侵袭Cupressus, Juniperus, Widdringtonia这几个属及柏科的其它原生种; 肯亚有东非桧木最大的工业用人工种植区(约八万六千公顷),其中5153公顷已遭受柏蚜程度不等的危害(Mwangi, 2002); Mwangi (2002)说柏蚜的密度会在干、热的季节达到最高,在雨量最多的时候密度最低。柏蚜的密度降低时,一些受伤的树便有机会康复。
