【摘要】 滇中地区有3种切梢小蠹危害云南松,主要虫种是横坑切梢小蠹,云南切梢小蠹次之,短毛切梢小蠹只在曲靖地区发现。由北向南云南切梢小蠹的比例逐渐降低,横坑切梢小蠹的比例逐渐增高。横坑切梢小蠹主要分布在1.5-2m以下的树干上,云南切梢小蠹主要分布在2-2.5m以上的树干上,其分布高度与树的高度无显著相关性;短毛切梢小蠹在树干上分布均匀。3种切梢小蠹占据树干的不同部位,交错时会相互避让,协同危害,加快树木死亡。更多还原

【Abstract】 In the middle of Yunnan province,Yunnan pines suffer damage from three Tomicus spp,the mainly specie is Tomicus minor,followed by Tomicus yunnanensis.Tomicus brevipilosus only occurs in Qujing.The proportion of Tomicus yunnanensis gradually reduced from north to south,whereas the proportion of Tomicus minor gradually increases.Tomicus minor mainly distributed in the stem of 1.5-2m below,Tomicus yunnanensis mainly distributed in the stem of 2-2.5m above,there were no significant differences with tree height and distribution height.Tomicus brevipilosus uniform distribution in stem.Each species occupy different position in stem,the tunnel is not intersect from each species,it cooperate with other on damage trees,speed up the tree dead.更多还原
