警惕检疫性害虫无花果蜡蚧在我国西南地区油橄榄种植区扩散

Be alert to the spread of a quarantine pest,Ceroplastes rusci(Linnaeus)in olive growing areas of southwest China

无花果蜡蚧是一种世界广泛分布的多食性害虫,取食56科160余种寄主植物,我国将该虫列为进境植物检疫性有害生物。2021年7—8月,作者在云南省迪庆州野外考察时,发现无花果蜡蚧取食多种植物,系滇西北地区首次发现,也是我国油橄榄、无花果和常春藤上发现的一种新害虫。滇西北以及金沙江干热河谷是我国西南地区油橄榄的重要种植区,为防止无花果蜡蚧的进一步为害,本文对其野外识别、主要显微特征和防治要点进行详细介绍。

Fig wax scale,Ceroplastes rusci(Linnaeus),is a widely distributed polyphagous pest in world,feeding on over 160 host plants of 56 families.It was listed as a quarantine pest in China.During the field investigation in Diqing Prefecture of Yunnan Province from July to August 2021,we found that C.rusci fed on several plants,which was the first time found in northwest Yunnan Province,and also a new pest found on olive(Olea europaea),fig(Ficus carica)and ivy(Hedera nepalensis var.sinensis)in China.Northwest Yunnan and the dry-hot valley of Jinshajiang River are important olive growing areas in southwest China.In order to prevent further harm of C.rusci,field identification,main microscopic characteristics and control points of fig wax scale were introduced in detail in this paper.
