摘　　要：本试验选择臭椿、苦楝树皮和叶片中生物活性物质的人工合成化学标样对天牛成虫做毒杀作用生物测定，发现α－蒎烯、β－蒎烯、α－萜品烯对天牛成虫有很强的毒杀作用，进一步揭示了臭椿抗天牛、驱避天牛的机理作用。The synthetic chemical standard samples of biological active substances in bark and leaves of tree of heaven and Kulian were chosen for biologicol identification of their toxic effect on longhorn beetle adults . It was found that αpinene,βpinene and αterpinene had a strong toxic effect on longborn beetle adults. The mechanism of tree of heaven's resistance to, expelling and avoiding, longhorn beetle was further studied.
