Aphids are small (1.5–3.5 mm), soft-bodied insects (Blackman and Eastop, 2000) that feed exclusively on sap from the vascular tissues of plants, mainly the phloem.
There are many symptoms of aphid damage, including decreased growth rates, mottled leaves, yellowing, stunted growth, curled leaves, browning, wilting, low yields and, eventually, death. Along with the loss of plant juices from direct feeding, aphids can spread diseases.
