Aphids excrete a sugary liquid called honeydew, because the plant sap from which they feed contains excess carbohydrates relative to its low protein content. To satisfy their protein needs, they absorb large amounts of sap and excrete the excess carbohydrates. Honeydew is used as food by ants, honeybees, and many other insects.
Aphis gossypii is a tiny insect, an aphid ("greenfly") in the superfamily Aphidoidea in the order Hemiptera.It is a true bug and sucks sap from plants. It is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae. [2]
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.

Honeydew is a sugar-rich sticky liquid, secreted by aphids, some scale insects, and many other true bugs and some other insects as they feed on plant sap. 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 ...
The adults of Eriosoma lanigerum are small to medium-sized aphids, [4] up to 2mm long, and have an elliptical shape, are reddish brown to purple in colour but the colour is normally hidden by the white cotton-like secretion from the specialised glands in the aphid's abdomen which gives it the common name of woolly apple aphid.
Honeydew is a sugary excretion from plant sap sucking insects such as aphids or scales. There are many trees that are hosts to aphids and scale insects that produce honeydew There are many trees that are hosts to aphids and scale insects that produce honeydew
Tuberolachnus salignus uses two stylets to extract the sap flowing within the phloem. [4] [5] One is used to inject saliva into the phloem, while the other is used to ingest the sap and saliva mixture. [4] [5] Willow sap is an extremely nutritious food source, as it provides critical sugars and water to various parts of the willow tree.
