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
Beneficial Insects for control
Aphidius spp. (Hymenoptera: Braconidae)
-parasitic wasps
-lays eggs in individual aphids
Aphidoletes aphidimyza (Diptera: Cecidomyiidae)
-predatory larvae
-midge lays eggs near aphid colonies
-works well in combination with Aphidius spp.

piercing-sucking mouthparts
larvae are tiny crawlers, pointed at both ends
adults are tiny winged insects (0.5- 1.4 mm)
fringes along both edges of wing
colour: light tan to brown to black depending on the species (some are striped on their backs
Damage
often feeding is on young leaves and flowers causing distortion in plant growth
piercing mouthparts damage leaves, fruit, and flowers leaving silvery/ grey patches on the leaves
black fecal pellets called frass is often left in the damaged area
frass can be a problem, causing sooty mold to occur

-plant sap is removed from the leaves and young shoots causing plant stunting and leaf drop
-excretion of honeydew, reducing photosynthesis and causing sooty mold to colonize on the leaves
-often a disease vector, ingesting virus particles when feeding and spreading them to other plants
