金环胡蜂和黄脚胡蜂表皮化学成分差异分析

Difference Analysis of the Chemical Composition of the Cuticular of Vespa Mandarinia and Vespa Velutina

  • 摘要: 通过诱捕法收集金环胡蜂和黄脚胡蜂2种活体昆虫,利用气相色谱−质谱联用技术,分析2种胡蜂表皮化合物的主要成分。结果表明:从2种胡蜂表皮中共鉴定出32种化合物,以烃类、羧酸类和醇类为主,占测定化合物种类数量的70.97%;2种胡蜂表皮化合物的种类和含量均有差异,金环胡蜂表皮中相对含量最多的5种化合物为13−甲基二十七烷(32.31%)、2−甲基二十四烷(23.53%)、三十二烷(14.61%)、(E)−9−十八烯酸(12.80%)、胆固醇(5.70%),黄脚胡蜂表皮中相对含量最多的5种化合物为二十烷(22.45%)、亚磷酸三(2,4−二叔丁基苯基)酯(19.13%)、三十二烷(17.55%)、(E)−9−十八烯酸(15.66%)、13−甲基二十七烷(5.52%);2种胡蜂表皮相对含量最高的5种化合物中,2−甲基二十四烷只存在于金环胡蜂中,三十二烷和(E)−9−十八烯酸在2种胡蜂表皮中相对含量接近,二十烷、13−甲基二十七烷、亚磷酸三(2,4−二叔丁基苯基)酯在2种胡蜂表皮中相对含量差异较大。对2种胡蜂表皮化合物的研究有助于进一步揭示其生活习性和行为特征,可为更好开展虫害防治和绿色防控提供参考。

     

    Abstract: In order to clarify the main components of the cuticular compounds of the Vespa mandarinia and Vespa velutina, we analysed the chemical composition of the cuticular of the two wasps using gas chromatography-mass spectrometry. The results showed that a total of 32 compounds were identified from the cuticular of the two wasps, dominated by hydrocarbons, carboxylic acids and alcohols, which accounted for 70.97% of the determined compound species. The types and contents of cuticular compounds differed between the two wasp species. The five most abundant compounds in Vespa mandarinia were 13-Methylheptacosane (32.31%), 2-Methyltetracosane (23.53%), Dotriacontane (14.61%), (E)-9-Octadecenoic acid (12.80%), and Cholesterol (5.70%), while the five most abundant compounds in Vespa velutina were Eicosane (22.45%), Tris(2,4-ditert-butylphenyl) phosphite (19.13%), Dotriacontane (17.55%), (E)-9-Octadecenoic acid (15.66%), and 13-Methylheptacosane (5.52%). Of the five compounds with the highest relative amounts in the two wasps, 2-Methyltetracosane was present only in the Vespa Mandarinia. The relative contents of tridecane and (E)-9-Octadecenoic acid were relatively close in the cuticular of the two wasps, while the relative contents of Eicosane, 13-Methyloctadecanes, Tris(2,4-ditert-butylphenyl) phosphite had large variations in the cuticular of two wasps. The study of the cuticular compounds of two wasp species can help to further reveal their habits and behavioural characteristics, with a view to providing a reference for better pest control and green prevention and control.
