Nation, M. Sanford, K. Milne] 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. Elsevier Science Publishers B.V., 1993 Nation J.
