我国新发现一种重要外来入侵害虫——海枣异胸潜甲Javeta pallida Baly

Discovery of an important invasive insect pest, Javeta pallida Baly(Coleoptera, Chrysomelidae) in China

在我国广西和海南首次发现了一种新的重要外来入侵害虫:海枣异胸潜甲Javeta pallida Baly。该虫原产于印度南部,近年来才发现它取食银海枣。由于发生量大,造成银海枣大量叶片枯黄,严重影响银海枣的健康生长。刺葵属植物造型美观,我国南方栽种较多,它的扩散及为害应引起关注。本文描述了成虫、幼虫和蛹的形态特征,包括雄性外生殖器的特征,并附有为害状和形态特征图。
