摘　　要：相思拟木蠹蛾Arbela bailbarana是油茶重大害虫,标准地调查和防治试验结果表明,在广西相思拟木蠹蛾对油茶成熟林危害严重,其幼虫主要从枝干的分叉、伤痕、节疤等处侵入,虫道形状有4种,晚上外出成片或跳跃式啃食树皮.相思拟木蠹蛾对油茶枝干及其高度的危害有选择性,从油茶树干基部向上51 ～200 cm处、直径2.1～6.0 cm的枝干虫孔数最多,受害最重.虫道注射44％氯氰·丙溴磷乳油100～500倍液防治相思拟木蠹蛾大龄幼虫效果均十分明显,虫道插入竹签捅刺幼虫方法因虫道形状多变捅刺死亡率低不宜采用.Arbela bailbarana is a major pest on Camellia oleifera. The results of standard plot investiga- tion and control experiment showed in Guangxi,A. bailbarana caused serious damage in the mature fo- rest of C. oleifera. The larvae mainly invaded the trees from the bifurcations, scars and knots of bran- ches and went out at night to eat barks. The number of pest holes on trunks and branches with diameters of 2. 1450 cm at the height of 51-200 cm of the trees was the largest. The control effect of tunnel injec- tion of cypermethrin profenofos 44% EC 100-500 times was obvious.
