摘要
对松十二齿小蠹(Ips sexdentatus Boerner)进行了危险性评估分析,该虫在中国的危险性综合评价值(R)为1.628,为中度危险林业有害生物。虽然该虫目前在我国仅有局部发生,但能危害大部分松树,无论对衰弱木或健康的活立木,其侵害攻击力和适应性都很强。因此,应加强内部检疫和口岸检疫,防止传播蔓延。
The risk of lps sexdentatus Boerner invading pine trees in China was analyzed and evaluated. The synthesizing value （R） for the risk of this pest was 1.628, namely, it was a middle risk forest pest. Although this pest occurs at present only in a few areas in China, but it can invade most pine species, and its invading-attacking capacity and adaptability to hosts and circumstances are very powerful. Thus the internal quarantine and port quarantine must be strengthened in order to control its spread in China.
