Sugarbeet root aphid

Sugarbeet root aphid, as the name implies, is restricted to the roots; generally, the aphid is associated with fibrous roots rather than the main storage root. Winged aphids may occasionally be seen in woolly wax masses in the crown as they crawl up from the roots to fly to new hosts. Wingless forms found on roots are yellowish in color and secrete a dull, white waxy substance, giving the root a mealy appearance.
