摘　　要：椰心叶甲除危害椰子等棕榈科植物外,还危害香蕉。通过对香蕉叶的取食能够完成世代的繁殖,卵的孵化率为79.6%,幼虫的成活率为61.3%。既然椰心叶甲能通过取食香蕉叶完成世代繁殖,就证明其已对香蕉树生长产生威胁,应高度关注其对香蕉的危害。Besides palmaceous plants such as coconut,Palm leaf beetle Brontispa longissim（Gestro） also endangers banana.It completes generation reproduction by feeding on banana leaves,the rate of its egg hatchability and larva survival is 79.6% and 61.3% respectively.Because it completes generation reproduction by feeding on banana leaves,which proves that Palm leaf beetle Brontispa longissim（Gestro） becomes a potential vermin for banana trees,its potential danger for banana should be greatly concerned.
