Occasionally aphids, particularly winged forms, of cowpea aphid, cotton aphid, potato aphid, and bird cherry-oat aphid may be found in sugarbeet. With the exception of potato aphid, they rarely, if ever, colonize sugarbeet. Control is rarely required when these species are present. Some of these species are known to vector Beet yellows virus and Beet mosaic virus, but their exact role is not thoroughly known.
