摘　　要：研究了褐纹甘蔗象Rhabdoscelus lineaticollis(Heller)入侵定殖能力。结果表明:以卵为初始种群,单株国王椰子树接入15粒以上定殖可能性较大;以成虫为初始种群,当有1对雌雄成虫侵入时褐纹甘蔗象就能成功繁殖。Asiatic palm weevil Rhabdoscelus lineaticollis （Heller） was a new alien pest in palm plants and caused serious damage to the hosts at some places in South China. Invasion and localization of the pest was studied and the results showed the probability of localization was high when the original population was more than 15 eggs per palm tree or a pair of adults successfully survived in one palm tree.
