Shoot feeding and trunk attack are two factors of tree death. The current studies were conducted under field conditions that the beetles were allowed to attack the shoots. Factors influencing shoot feeding by T. minor and T. yunnanensis were discussed. Result shows that there is a remarkable relationship between gallery length and shoot length, and this correlation is also noticeable between gallery length and shoot diameter. Positions of invading holes on the shoots (lower, middle, or upper) attacked by Tomicus determine the gallery length to a great extent, and there is a significant relationship between them. The main influence factors on shoot feeding by T. minor are positions of invading holes, while those on shoot feeding by T. yunnanensis are shoot length, shoot diameter and positions of invading holes.10aTomicus minor10aTomicus yunnanensis1 aGao, Yanfei1 aZhang, Ying1 aZhang, Zhen1 aWu, Wei  uhttps://weevil.myspecies.info/shoot-feeding-tomicus-coleoptera-scolytinae-pinus-yunnaensis-trees
