瘤胸天牛Aristobia hispida(Saunders)在海南岛危害花梨等檀属树种,是一种重要的蛀干性害虫。此虫为害普遍而严重,对本地特类商品材(花梨)和重要的紫胶虫寄主(南岭檀)的发展影响很大。为了寻找有效的防治措施,几年来我们作了初步研究,现整理报导如下,供有关方面参考。一、寄主和分布瘤胸天牛的寄主,据文献记载是桔类、金合欢类。又据一些高等院校的标本记录,其寄主尚有柳杉、胡枝子。但经过我们的初步调查,现已知此虫为害檀属的四个树种,即降香檀(花梨)、南岭檀、海南檀、印度檀等,而不为害钝叶檀、大果檀、思茅檀、黄檀。文献上关于为害桔类的记载,经过我们到两广地区的有关院校、柑桔场、研究所等调查访问,均称从未见有此虫为害柑桔。
