Abstract:According to the implementation of "Agreement on the Application of Sanitary and Phytosanitary (SPS) Measures " of WTO, the risk of the invasive pest, Brontispa longissima (Gestro) in China was analyzed in order to finalize the policy for the quarantine management of the pest. Based on the rules of pest risk analysis (PRA) of "International Standards for Pest Measurements" (ISPM) and the relational model of PRA, we categorized the risk level of Brontispa longissima using five indexes: the distribution, the potential degree of damage, the economical value of infected host plants, the possibility of transmission and spreading, and the difficulty of risk management in China. The values of the five indexes were calculated as 2, 2, 3, 2.05 and 1.66, respectively. The overall risk value of Brontispa longissima was 2.09, which has reached the level of the high risk quarantine pest in China. Finally, two strategies of the risk management for Brontispa longissima were evaluated and the better one was proposed.
