摘要:

红火蚁(Solenopsis invicta Buren)是一种真社会性昆虫,是世界上最具危险的100种入侵有害生物之一。红火蚁表皮碳氢化合物(cuticular hydrocarbons, CHCs)是其同巢识别的信号物质,对其种群的稳定具有重要作用。目前,已有关于红火蚁主要体表碳氢化合物在近缘种间和不同虫态及品级间的差异比较,但是不同地理种群和红火蚁身体不同部位CHCs组分及其相对比例的差异性却鲜见报道。本文利用气相色谱质谱联用技术(GC-MS)对浙江省温州、丽水及义乌3个不同地理种群红火蚁老龄工蚁的CHCs进行比较分析。结果表明,红火蚁头部CHCs含量最高,达到50%以上,其次是胸部和腹部,而且在其身体各部位之间显著差异,CHCs含量在不同地理种群之间无显著差异。进一步分析CHCs主要组分的相对比例发现,该数值在红火蚁头部表现较为规律,5种主要CHCs中的3-甲基二十七烷和3,9-二甲基二十七烷在不同地理种群之间较为波动,而正二十七烷、13-甲基二十七烷和13,15-二甲基二十七烷在温州和丽水种群之间较为稳定。本研究能为今后揭示遗传及环境因素对红火蚁巢间个体CHCs主要组分的调节机制提供重要参考依据。

Abstract:

Red imported fire ant (Solenopsis invicta Buren) is an eusocial insect, and is one of the 100 most dangerous invasive pests in the world. Cuticular hydrocarbons (CHCs) are important signal substances for nestmate recognition of S. invicta and play an important role in population stability. Recently, the differences of main CHCs of S. invicta among related species, different insect stages and various castes have been compared, but the differences of CHCs components and their relative proportions in different geographical populations and different body parts of S. invicta have been rarely reported. Here, the CHCs of 3 different geographical populations (Wenzhou, Lishui and Yiwu) of S. invicta were comparatively analyzed by gas chromatography-mass spectrometry (GC-MS). Further analysis of the relative proportion of the main components of CHCs showed that this value was relatively regular in the head of S. invicta. 3-methyl heptadecane and 3,9-dimethyl heptadecane in the 5 main CHCs fluctuated among different geographical populations, while n-heptadecane, 13-methyl heptadecane and 13,15-dimethyl heptadecane were relatively stable between Wenzhou and Lishui populations. This study can provide important reference for revealing the regulation mechanism of genetic and environmental factors on CHCs components of red imported fire ants.
