Abstract: 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.

Key words: Tomicus piniperda, Pinus yunnanensis, forest insect
