摘要
通过GC-MS顶空进样的方法测定油松、落叶松、马尾松和黄山松树皮的挥发性物质,显示α-蒎烯和β-蒎烯是树皮的挥发性物质中的主要成份;单一树皮饲喂证实红脂大小蠹对4种树皮均能钻蛀取食;嗅觉行为实验和取食趋向实验比较红脂大小蠹对4种针叶树树皮的行为趋向,结果表明4种树皮间存在差异性:对油松的选择趋向性最为明显;其次是落叶松;对马尾松和黄山松的趋向性较弱。4种松树树皮的挥发性成份的分析结果与红脂大小蠹对其的选择趋向性间相关性不明显。
The volatiles profiles of 4 kinds of Chinese pine,Pinus tabuliformis Carr,P.hwangshanensis Hsia,P.massoniana Lamb and Larix principis-rupprechtii Mayr were surveyed with Super-Q absorbent in headspace absorption method.GC-MS analysis showed that α-pinene and β-pinene were main components in all 4 conifers＇ barks.Single bark feeding test showed that Dendroctonus valens LeConte（Coleoptera： Curculionidae） can bore and feed on all 4 conifers＇ bark.Food approaching test and olfactometer were employed in laboratory and the behavioral responses of D.valens to the barks were different significantly.P.tabuliformis was most attractive to the insect,followed by Larix principis-rupprechtii.There was no significant relevance between the attraction of the insect to the barks and the components of its volatiles.
