危险性害虫褐纹甘蔗象的识别及风险性分析

Morphology and risk analysis of asiatic palm weevil Rhabdoscelus lineaticollis (Heller)

对棕榈科植物和甘蔗(Sacchrumsinensis)的重要害虫———褐纹甘蔗象(Rhabdosceluslineaticollis(Heller))的形态及为害特征进行了简要介绍,并运用有害生物危险性分析(PestRiskAnalysis,PRA)的方法,从国内分布状况、潜在危害性、寄主植物经济重要性、传播扩散的可能性以及危险性的管理难度等方面综合评价了该虫的危险性.结果表明,褐纹甘蔗象对我国是具高度危险性的有害生物.

Morphological features and damage of the Asiatic palm weevil Rhabdoscelus lineaticollis (Heller) (Coleoptera: Curculionidae), which had caused serious damage to the palm plants and sugarcane Saccharum sinensis in other several countries and districts, were described in brief in this paper. Main chavacteves of this pest, such as its distribution in China, potential damage to host plants, economical value of host plants, spreading possibility and control method of the asiatic palm weevil were evaluated with pest risk analysis. The result showed that weevil was dangerous devastator to palm plants and sugarcane in China.
