These insects suck the sap from plant leaves. Several thousand species are placed in this family , many of which are considered plant/crop pests. They are the family of insects containing most plant virus vectors (around 200 known) with the green peach aphid ( Myzus persicae ) being one of the most prevalent and indiscriminate carriers.
Some groups of aphids feed predominantly in the parenchymal tissue of plants while most aphid species feed on the phloem sap. [6] The green peach aphid ingests sugary fluids via a membrane. [12] While feeding on a plant long term, Myzus persicae can uptake chloroplast DNA, even though the chloroplasts themselves are uninjured.

When their mouthpart penetrates the phloem , the sugary, high-pressure liquid is forced out of the anus of the insects, allowing them to rapidly process the large volume of sap required to ...
Woolly aphids feed by inserting their needle-like mouthparts into plant tissue to withdraw sap. They are able to feed on leaves, buds, bark, and even the roots of the plant. As a result of feeding on the sap, woolly aphids produce a sticky substance known as honeydew, which can lead to sooty mold on the plant.
