family Aphididae

These small insects come in various colours; all attack leaves and stems of host plants, causing leaves to distort then fall, and covering them in sticky secretion called honeydew; the latter may in turn attract ants which will protect the aphid colonies in return for feeding on this honeydew. A problem with most fruits and vegetables.

Avoid a vegetable problem by starting plants indoors early, hardening off early, setting outside well before last frost, where possible. Pick off affected leaves, or spray with soap or oil solutions. Yellow sticky traps helpful with flying aphids

Aphid midge (Aphidoletes aphidimyza), ladybugs or convergent lady beetles (family Coccinellidae), lacewings (Chrysoperla carnea, C. rufilabrus) are all available commercially. Braconid wasps (Aphidius matricariae) are also used to control apple aphids. Pyrethrins and rotenone may be used as a last resort.
