摘　　要：20 0 1～ 2 0 0 2年在山西省榆次区庆城林场对自行研制生产的强大小蠹DendroctomusvalensLeConte植物引诱剂诱芯和诱捕器在林间的应用技术进行了研究 ,并在山西省的 1 3个县、林场悬挂 2 0 0 0个诱捕器开展了强大小蠹发生期监测和大面积诱杀防治推广试验工作。结果显示 ,该诱捕技术对强大小蠹成虫有较好的诱捕效果 ,2 0 0 0个诱捕器在成虫羽化期 61d共诱到大小蠹成虫近 2 0万头 ,可明显降低当代成虫虫口密度。试验表明 ,诱虫数量随林地虫口密度增加而增大 ,诱捕器设置高度对诱虫量有一定影响 ,以悬挂在主干下端距地面 5～ 1 0cm处效果最好。诱捕器之间水平距离建议间隔 1 0 0m为好。Trapping experiments on the red turpentine beetle, Dendroctonus vcalens, were conducted in Shanxi Province during 2001 and 2002. The results demonstrated that Lindgren Funnel traps set up 15 cm above the ground were best for this beetle. Mass tapping can significantly reduce the beetle attack damage but trees immediatly surrounding traps sustained heavy beetle attack. Verbenone used in conjunction with trapping as a push/pull method can effectively protect these surrounding trees but also reduces trapping efficacy. Trapping efficacy was also positively correlated with the beetle density in the stand.
