Aphids feed on a wide range of greenhouse crops.
A number of species exist, but one of the most common is the green peach aphid. They feed particularly on buds and the undersides of leaves by inserting their tube-like piercing mouthparts and withdrawing sap. A secondary problem arises from sugary honeydew excreted by the aphids. Also, aphids are able to transmit viral diseases. Aphids normally give birth to living female nymphs.
