Green apple aphid nymphs and adults prefer to feed on the underside of leaves on growing shoot tips and stems.

The winged adult (about 3 mm) has a black head and thorax, and a yellowgreen abdomen. Wingless adults are green with black cornicles, legs and antennal tips. Nymphs are about 1.5 mm long.

  • Damage

    Estimate the average number of aphid-infested leaves on terminals. Generally, an average of 3 to 4 infested leaves is needed before fruit damage from honeydew occurs. In young orchards, lower levels of aphid infestation (1-2 leaf colonies) will inhibit growth of the trees.
