无花果蜡蚧在广东地区的寄主范围及危害分析

Analysis on Host Range and Damage of the Ceroplastes rusci in Guangdong

无花果蜡蚧是近年来入侵我国的一种检疫性害虫,对我国园林绿化树种和经济作物造成了严重危害,摸清该害虫在我国的适生寄主范围和危害情况,可为开展预测预报和防治工作提供基础资料。本文通过野外实地采样调查和查阅相关文献资料,对无花果蜡蚧的寄主范围及危害情况进行统计分析,其寄主极为广泛,共有160余种,隶属于56科。实地调查发现,无花果蜡蚧在广东地区存在16种寄主,其中10种为新发现寄主,受害最为严重的是秋枫和杂色榕。结果表明,无花果蜡蚧在广东地区已定殖,对当地农林业生产的危害日益突显,为了防止其进一步扩散蔓延,相关部门应引起重视,及时开展外来入侵生物风险评估,制定有效的防治措施。

The fig wax scale scientific name:Ceroplastes rusci(Linnaeus)is a quarantine pest invading China in recent years.It has caused serious damage to landscape trees and economic crops.Finding out the suitable host range and damage situation of the pest in China can provide basic data for its prediction and control.In this paper,through field investigation,sampling and consulting relevant literature and database,the host and harm of fig wax scale in China were statistically analyzed.The host is extremely wide,with more than 160 species belonging to 56 families.According the field investigation,there were 16 hosts of fig wax scale in Guangdong province,10 of which were newly discovered hosts.The most seriously affected hosts were Bischofia javangca and Ficus variegata.The results show that the fig wax scale has been colonized in Guangdong,and its harm to local agriculture and forestry has become increasingly prominent.In order to prevent its further spread,relevant departments should pay attention to the risk assessment of invasive alien species in time and formulate effective prevention and control measures.
