摘要
椰心叶甲已在我国30个县(市)造成了严重危害,为防止其扩散加剧、有效地开展综合防治工作,利用GARP生态位模型进行潜在分布区预测。结果表明:我国南方较广大的地区适宜椰心叶甲的生存,潜在分布区涉及广东、福建等12省区大部地区和云南等7省区的局部地区;原有受害省区内的潜在分布区远远超过当前的分布区。为明确椰心叶甲向北扩散的可能性,建议尽快开展耐寒性方面的研究。
Brontispa longissima （Gestro）, causing heavy damage in 30 counties in southern China where palm trees were distributed, was established in China. To contain its further spread and take effective management measures, GARP Modeling was used to analyze the potential geographic distribution of the coconut leaf beetle. The results indicated that the beetle could be established in most provinces in southern China including most areas in 12 provinces （e. g. Guangdong, Fujian） and limited area in 7 provinces （e. g. Yunnan）. To accurately define the northern limit of its further spread, it is suggested to carry out researches on the cold hardiness of the beetle as soon as possible.
