新入侵种刺桐姬小蜂在中国的危险性评估

Potential risk assessment of a new invasive pest,Quadrastichus erythrinae,to the mainland of China

采用GARP生态位模型预测分析了刺桐姬小蜂Quadrastichus erythrinaeKim在中国的潜在地理分布,并参照国际上有害生物危险性定量分析方法,对刺桐姬小蜂在中国的危险性作出综合评价。结果表明:中国东南部大部分地区都是该虫的适生区。在福建、广东、海南地区风险值为2.0585,存在高度危险性;在其他东南部省区存在中度危险性。据此提出了针对性的风险管理措施。

We predicated the potential distribution and damage of Quadrastichus erythrinae Kim in China based on the CRAP model in the paper. The result showed that Q. erythrinae could establish in the most areas of the southeastern China but Fujian, Guangdong and Hainan Provinces are at high risk as their risk value is 2. 0585. The risk management strategy for different risk areas were discussed.
