Aphid Control

Identification: many different species of aphids occur in the greenhouse, all varying in size and morphology; (0.5- 6.5 mm long)
Colour: green to black, yellow, brown, purple, pink, grey, white piercing-sucking mouthparts can often be identified by the cornicles (tubes) from the end of the abdomen
-sometimes present in a winged (alate) form usually found in the wingless form (apterous)
Damage: plant sap is removed by the stylet, causing deformed leafs and shoots excretion of honeydew, reducing photosynthesis and causing sooty mold to colonize on the leaves often a disease vector for viruses.
