摘　　要：在昆明地区,纵坑切梢小蠹TomicuspiniperdaL.表现出枝梢聚集、树干蛀害等重要的行为学特征,形成三种基本蛀害模式。横坑切梢小蠹、蓝色伴生真菌参与了纵坑切梢小蠹危害过程,并在其中发挥积极作用。上述因素的综合影响,加强了纵坑切梢小蠹对云南松Pinusyunnanensis寄主树木的危害能力。In the present paper, the studies were made on the damages of Tomicus piniperda (Col., Scolytidae) including the shoot feeding and the trunk attacking on Pinus yunnanensis trees in Yunnan Province, in southwestern China. The three basic damage patterns in the trunk attacking developed by the beetle were revealed. Tomicus minor and blue stain fungi were found to be involved in T. piniperda damages. The three damage patterns, in association with Tomicus minor and blue stain fungi, made the integrated function, which is proposed to strengthen the damages of T. piniperda to Yunnan pine trees.
