摘要：

Epicuticular lipids provide the primary barrier to water loss in insects and other terrestrial arthropods. Using Fourier transform infrared spectroscopy, we found that the melting temperatures for these lipids in the grasshopper Melanoplus sanguinipes varied by over 10-degrees-C between individuals. The most significant determinant of lipid melting temperature was geographic population, followed by family effects and rearing regime. The width of the phase transition also showed population and family effects. Differences in lipid phase properties were correlated with habitat temperature. Our results provide evidence for genetically based intraspecific variation in epicuticular lipids and have important implications for physiological studies of water balance in arthropods.
