中文摘要：
【目的】 报道桉弗天牛Phoracantha semipunctata Fabricius在我国的野外定殖，并评估其风险等级。【方法】 通过野外踏查以及飞阻和马氏网等被动采集方法，在广东省桉树林进行昆虫采集；利用形态学研究方法对采集到的昆虫进行鉴定。根据森林、草原和湿地生态系统外来入侵物种风险评估指标体系，对桉弗天牛在我国的入侵风险进行定性和定量分析。【结果】 在广东省广州市、东莞市、中山市和韶关市发现了桉弗天牛的野外定殖，风险分析结果显示，桉弗天牛在森林草原湿地生态系统的风险评估值P为0.87，目前属于低度危险的有害生物。【结论】 桉弗天牛在我国为低度危险的有害生物，零星分布，需加强监测并开展生物学及防治方向的研究。
英文摘要：
[Aim] To report the presence
of an introduced species Phoracantha
semipunctata Fabricius in China, and evaluate the risk posed by this species. [Methods] Manual
investigation, flight intercept traps and Malaise traps were used to collect
insects in Eucalyptus forests of Guangdong Province. Identification was
based on morphological characters. Risk level was analyzed based on the risk
assessment indicator system of invasive species in forest, grassland and
wetland ecosystems provided by the National Forestry and Grassland
Administration. [Results] The introduced species P.
semipunctata was found to have colonized Guangzhou, Dongguan, Zhongshan and
Shaoguan in Guangdong province, and its risk value (P) was assessed as
0.87 in forest, grassland and wetland ecosystems, which is indicative of a low
risk pest at present. [Conclusion] P. semipunctata is a low
risk pest in China and sporadically distributed at present, which required
enhancement of monitoring and studies on the biology, prevention and control.
