Sitobion avenae (Fabricius, 1775) (grain aphid)
The aphid is one of the main aphid pests of wheat in Europe, the Americas and parts of Asia. It feeds on the leaves and developing ears and can also infest other cereals and grasses. Yield losses of up to 40% have been reported. In addition, it is a vector of several plant viruses, in particular, it transmits the Barley yellow dwarf virus MAV.
Apterous adults are 1½-3 mm large, green, sometimes slightly reddish in colour. The siphunculi, most of the antennae and parts of the legs are dark to black. It goes through several parthenogenetic and wingless generations before producing winged forms which disperse.
