The yellow sugarcane aphid is usually lemon yellow but
under some conditions is pale green, 2 mm long, covered with short, black spines, and has
two double rows of dark spots on its back (Color Plate 6). Cornicles are very short.
Winged and wingless forms live in the colony. The wide range of wild hosts includes
johnsongrass and dallisgrass, Paspalum dilatatum Poir. Without mating, females give
birth for twenty-eight days to living young. Each female produces an average of two nymphs
per day. Nymphs mature in thirteen to nineteen days. |
