摘要
【目的】分析外来入侵害虫新菠萝灰粉蚧(Dysmicoccus neobrevipes Beardsley)在中国的风险性。【方法】根据国际植物检疫措施标准(ISPM)规定的有害生物风险性分析(PRA)程序,本文从新菠萝灰粉蚧国内分布状况、潜在危害性、受害栽培寄主的经济重要性、传播扩散的可能性及危险性管理难度等5个方面对其在中国的风险性进行了定性、定量分析。【结果】新菠萝灰粉蚧在中国的综合风险值R为2.12。【结论】表明新菠萝灰粉蚧在中国是高度危险的检疫性有害生物。
[Objective] The risk of alien invasive gray pineapple mealybug （Dysmicoccus neobrevipes） Beardsley, in China was analyzed. [Method] Based on the rule of pest risk analysis （PRA） of international standards for pest measurements （ISPM）, quantitative and qualitative analysis was conduced on the risk level of D. neobrevipes in five aspects： distribution, potential damage level, economic value of damaged host plants, spreading probability and risk-management difficulty in China. [Result] The synthetic index of the pest risk in China is estimated to be 2.12. [ Conclusion ] The result indicats that D. neobrevipes is a dangerous alien species with high risk in China.
