| 摘 要： | 红缘天牛Asias halodendri(Pallas)和槐绿虎天牛Chlorophorus diadema(Motschulsky)是危害四合木的重要天牛.作者调查了两类不同土质及植被组成的样地,全株解剖受害四合木,统计幼虫的危害位置.结果显示,两种植被条件下,植被种类、长势及天牛幼虫对四合木的危害程度不同.其中,在四合木长势好的环境中,害虫危害轻.两种天牛幼虫倾向于危害直径在0.5～1.6 cm之间的四合木枝条,集中分布在地上7 cm以下的枝条内.

| Abstract: | Asias halodendri(Pallas) and Chlorophorus diadema(Motschulsky) were significant pests attacking Tetraena mongolica Maxim.The two pests were studied under two different circumstances with varied vegetation compositions and all the larvae' locations were recorded.The results showed that the damage on T.mongolica in the better environment was less severe than that in the worse.The larvae of the two species were tended to attack the stems with diameter between 0.5-1.6 cm and aggregate mainly in the stems at the... |
