Woolly Aphids are sap-sucking insects in the aphid family, Aphididae. They're very small, reaching up to 2mm and are a reddish, brown colour. The main symptom associated with these aphids is the mass of white 'cotton-wool' wax-covered branches of the trees they infest. Other symptoms include clear, sticky honeydew and sooty moulds on leaves. They can also cause plants to produce galls. These pests favour species in the genera Malus, Cotoneaster and Pyracantha.
Sucks the sap from plants.
Aphids are food source for ladybird, hoverfly and lacewing larvae.
Adults: They grow up to 2mm in length and are reddish-brown or purple, although you can not see their colour usually as they are covered in a white, cotton-like secretion that they produce from specialised glands. When crushed, the aphids will leave red stains. Nymphs: Young aphids are generally smaller in size. Wings are undeveloped, so they can't fly. Nymphs can either be rusty yellow-brown or a reddish-brown.
Copious amounts of honeydew. Growth of black mould. Damage seldom permanent. Plants may begin to wilt and die back. Ants may be found near or on the infested plants. Young plants are impacted worse. Galls on stems and roots. Canker on stems.
By introducing the chalcid wasp, Aphelinus mali you can decrease the production of the aphids wax. They then turn black in colour. Other bugs such as ladybirds, hoverfly and lacewing will also help to reduce the number of aphids on your plants. You can also easily just cut away the affected areas and destroy the infected branches.
Spot treating your plants and trees where the aphids are present is one of the most effective ways of getting rid of them. Insecticidal soap and neem oil are effective treatments. You can also use insecticide such as acephate for fast results. However there are many alternative and less harmful methods of control. If a chemical option is sought, check with your local garden centre and please take care to follow the manufacturers' instructions. Also check with your local regulating body for guidance on active ingredients and their authorisation for use.
