摘要
对三清山高海拔栎林中云斑白条天牛Batocera lineolata Chevrolat补充营养、产卵刻槽、排粪孔、羽化孔等危害情况进行调查。结果表明,云斑白条天牛成虫与幼虫的主要寄主均为小叶青冈和多脉青冈。成虫啃食1～2 a生的枝皮补充营养。同一受害植株,树干阳面受害重。受害树木胸径集中在14～31 cm范围内。虫害部位主要分布在树干4 m以下区域。统计分析表明小叶青冈受害株产卵刻槽数与胸径呈负线性相关,羽化孔、产卵刻槽高度与胸径呈正线性相关;幼虫活动区间(羽化孔与产卵刻槽的高度差)与胸径相关不显著。
The supplementary nutrition,oviposition nidi,frass holes and emergence holes of Batocera lineolata were investigated in high altitude oak forests of Sanqingshan Mountain.The major hosts of B.lineolata were Cyclobalanopsis myrsinaefolia and C.multinervis.The adults fed on the bark of 1-2 years old branches.The trees were attacked more seriously on the sunny sides of the trunks.The diameters at breast height（DBH） of the infested trees were about 14-31 cm.The pest mainly attacked the trunk at the height below 4 m.Statistical analysis indicated that in Cyclobalanopsis myrsinaefolia,the numbers of oviposition nidi had a negative linear correlation with DBH and the heights of emergence holes and oviposition nidi had positive linear correlations with DBH.However,the activity ranges of larvae had no significant correlation with DBH.
