纵坑切梢小蠹Ｔｏｍｉｃｕｓｐｉｎｉｐｅｒｄａ在云南分布很广，８０年代以来，在昆明、红河、楚雄３地、州３０个县的云南松人工林内猖獗危害，直接经济损失６０００余万元。该虫在云南１ａ一代，全年危害，无明显的越冬现象。每年５～１１月蛀梢，１１～翌年５月蛀干，树皮下各虫态种群高峰期出现在２～５月，此时是清理蠹害木的最佳时期。成虫干转梢及由梢转干在林间扬飞期１～１４ｄ，集中扬飞３～４ｄ，扬飞期对防治成虫有重要意义
Tomicuspiniperda is widely distributed in Yunnan. Since the 1980s, it has been rampant in the Pinus yunnanensis plantations in 30 counties, including Kunming, Honghe and Chuxiong, and has a direct economic loss of over 60 million yuan. The insects in Yunnan 1a generation, year-end hazards, no obvious winter phenomenon. From May to November each year, the moths were moth-eaten, and the moths were allowed to dry in May-November the following year. The peak period of all the insect-state populations in the bark appeared from February to May, at this time the best period for cleaning the moths. Adult stems and shoots turn dry shoots in the forest during the flying period of 1 ~ 14d, focus flying 3 ~ 4d, Yang Fei period for the prevention and control of adults is of great significance
