稻水象甲入侵四川的风险分析

Risk analysis of invasion of Lissorhoptrus oryzophilus Kuschel in Sichuan

为了分析稻水象甲(Lissorhoptrus oryzophilus Kuschel)在四川的风险性,根据国际植物检疫措施标准(ISPM)规定的有害生物风险分析(PRA)程序,从省内外分布状况、潜在经济危害性、寄主植物经济重要性、传播扩散可能性和危险性管理难度等5个指标对稻水象甲在四川的风险性进行了分析。研究表明稻水象甲的综合风险值为2.09,为高度危险检疫性有害生物。稻水象甲对四川稻区具有高度危险性,为确保水稻安全生产,应对其加强检疫、加大监测和扩大宣传。

The risk of Lissorhoptrus oryzophilus Kuschel in Sichuan was analyzed. According to the rule of pest risk analysis （PRA） of international standards for pest measurements （ISPM） ,quantitative and qualitative analysis of Lissorhoptrus oryzophilus Kuschel in Sichuan was carried in five aspects：distribution,potential damage level,economic value of damaged host plants,spreading probability and risk-management difficulty in Sichuan. The synthetic index of the pest risk in Sichuan is estimated to be 2.09,for the highly dangerous quarantine pest. The result indicates that Lissorhoptrus oryzophilus Kuschel is a dangerous alien species with high risk in Sichuan. To make sure the safety in production for rice,the measures which could be used include strengthening the quarantine,stepping up the efforts in surveillance and making great efforts on propaganda.
