采用气相色谱（GC）和气质联用（MS）对采集自佛罗里达和意大利的瓦螨及其蜜蜂寄主的表皮烃进行了表征。阿瓦螨具有与其蜜蜂宿主在性质上相同的碳氢化合物模式。螨和蜜蜂的所有阶段都有一种特征性的挥发性烷烃组分模式，包括二十一烷、二十三烷、二十五烷、二十七烷、二十九烷和三十一烷。成年蜜蜂和来自成年蜜蜂的螨也具有烯烃8-nC 31：1、10-nC 31：1和10-nC 33：1作为主要组分，而蛹和来自蛹的螨仅具有这些烯烃的痕量。使用添加二甲基二硫醚（DMDS）后的耦合GC-MS分析来确定上述三种主要烯烃中双键的位置。螨类是否只是从宿主那里获得碳氢化合物，或者可能是合成碳氢化合物的问题还没有解决。意大利和佛罗里达的螨的碳氢化合物之间没有特征差异被发现。我们推测，碳氢化合物帮助螨避免干燥，并可能有助于螨融入蜂群生活。
The cuticular hydrocarbons fromVarroa mites collected in Florida and Italy and their honeybee hosts were characterized by gas chromatography (GC) and by coupled GC-mass spectrometry (MS). AVarroa mite has a hydrocarbon pattern that is qualitatively identical to that of its honeybee host. Mites and all stages of honeybees share a characteristic pattern of prominant alkane components including heneicosane, tricosane, pentacosane, heptacosane, nonacosane and hentriacontane. Adult honey bees and mites from adult bees also have as major components the alkenes 8-nC31:1, 10-nC31:1 and 10-nC33:1, while pupae and mites from pupae have only traces of these alkenes. Coupled GC-MS analysis after addition of dimethyl disulfide (DMDS) was used to determine the location of the double bound in the three prominent alkenes above. The question as to whether the mites simply acquire the hydrocarbons from their hosts or possibly synthesize them was not resolved. No characteristic differences between the hydrocarbons of mites from Italy and from Florida were found. We speculate that the hydrocarbons help the mites avoid desiccation and may help integrate the mites into honeybee colony life.
