【摘要】 在松纵坑切梢小蠹的综合防治中，蠹害木的清理是一重要环节。依据在轻、中、重受蠹害云南松林区进行的蠹害木清理试验结果，一般情况下，对轻度受害区即被害株率在10%以下，蠹害指数在5以下，清理蠹害木应控制在1.00%；对中度受害区，即被害株率在10%～50%，蠹害指数在5～15，清理蠹害木应控制在10.00%左右；重度受害区，即被害株率在50%以上，蠹害指数在15以上，清理蠹害木应控制在20.00%左右。在重度受害区，除清理蠹害木外，还需辅以其他措施，进行综合治理才能有效控制蠹害。更多还原

【Abstract】 To clear Tomicus piniperda damaged woo ds is one of the important steps in the integrated control of Tomicus pin iperda.According to the results of experiment on clearing of the damaged woods in light, moderate and heavy damaged Pinus yunnanensis fores t regions, generally, in light damaged regions (the percentage of damaged trees is lower 10%, and the index of damaged is lower 5%), clearance should be control led to 1.00% In moderate damaged regions (the percentage of damaged trees is 10%～50%, and the index of damaged is 5%～15%), clearance should be controlled t o 10.00% or so. In heavy damaged regions (the percentage of damaged trees is hi gher 50%, and the index of damaged is higher 15%), clearance should be controlle d to 20.00% or so, and other supplementary measures should be taken to clear th e damaged woods in these regions at the same time.更多还原
