Riley, Charles Valentine, 1843–95, American entomologist, b. England. He emigrated to the United States in 1860 and served as state entomologist (1868–77) of Missouri and as entomologist (1878–79, 1881–94) in the Dept. of Agriculture. Riley has been called the father of modern economic entomology. His observations and suggestions helped control the destructive cottony cushion scale in California (by introducing parasites from Australia) and virtually saved the wine industry of France from the grape phylloxera phylloxera , small, sap-eating, greenish insect of the genus Phylloxera, closely related to the aphid. Phylloxeras feed on leaves and roots, and many species produce galls on deciduous trees.
