Data from: On the scent of standing variation for speciation: behavioral evidence for native sympatric host races of Rhagoletic pomonella (Diptera: Tephritidae) in the southern United States

Thomas H. Q. Powell, , Dong H. Cha & Jeffrey L. Feder
Standing variation can be critical for speciation. Here, we investigate the origins of fruit odor discrimination for Rhagoletis pomonella underlying the fly’s sympatric shift in the northeastern U.S. from downy hawthorn (Crataegus mollis) to apple (Malus domestica). Because R. pomonella mate on host fruit, preferences for natal fruit volatiles generate prezygotic isolation. Apples emit volatiles that appear to be missing from gas chromatography/electroantennographic detection profiles for flies infesting downy hawthorns, raising the question of how...
