摘 要:云南松纵坑切梢小蠹的发生与气候因子关系密切。大气湿度低、气候干旱,入侵严重;温度越高,小蠹发育速度越快,侵入成功率越高;云南松林立地条件差、阳坡、山脊、林缘、郁闭度低、长势弱均易遭蠹害。森林火灾、乱砍滥伐造成小蠹虫的虫源地。In Yunnan Province, there is a close relationship between the occurrence of Tomicus piniperda and climatic factors. If the atmospheric humidity is low, the attack will be serious, and the higher the atmospheric temperature, the higher the survival rate of Tomicus piniperda. The poor site condition of Pinus yunnanensis forest, especially on tailo, mountain ridge and forest edge are the places damaged by Tomicus piniperda seriously. Moreover, wanton felling of trees and forest fire resulted in the insect-source sites. Due to the reasons above-mentioned, there is a large area of Pinus yunnanensis forest attacked by Tomicus piniperda in Yunnan province.
