摘要:

在采用TCT-GC/MS对松果梢斑螟不同危害期红松挥发性物质分离鉴定的基础上,分析松果梢斑螟越冬幼虫对越冬幼虫转移危害期红松不同组织挥发性物质的嗅觉反应。结果表明,松果梢斑螟不同危害期红松球果及越冬幼虫转移危害期红松不同组织挥发性物质的组成与含量均存在差异; 红松健康球果、健康2年生枝和针叶主要挥发性物质标样乙醇溶液对越冬幼虫的引诱作用显著高于乙醇对照组,而红松健康球果主要挥发性物质标样乙醇溶液的引诱作用显著大于健康2年生枝与针叶主要挥发性物质标样乙醇溶液; α-蒎烯、柠檬烯及α-蒎烯+β-蒎烯乙醇溶液对越冬幼虫的引诱作用明显强于红松健康球果主要挥发性物质标样乙醇溶液,且以α-蒎烯的引诱作用最强。

Abstract:

Composition and relative contents of volatiles from different tissues of Pinus koraiensis at different stages after infested by Dioryctria pryeri by using TCT-GC/MS technique and olfactory response of larvae to the volatiles were further analyzed. The result showed that there were differences in volatile composition and contents from the pine cones infested by D. pryeri and the other different tissues infested by the pest larvae in overwinter at different infesting stages. Olfactory response of overwinter larvae indicated that the simulated overwinter larvae obviously prefered alcohol solution with standard sample of main volatile components from healthy cones, healthy branches and needles to alcohol solvent; and the larvae had an obvious orientation to healthy cones compared with the branches and needles. In addition, they had an orientation to alcohol solution with α-pinene, limonene, α-pinene+β-pinene compared with standard sample of main volatile components from healthy cones of Pinus koraiensis, among which α-pinene had the strongest attract ability.
