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。 In pine pits cut moths comprehensive prevention and control, the moth harm wood cleaning is an important part.
