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… CONTINUE READING
