Pine (Pinus)-Pine aphid

Cinara strobi

Pest description and damage Cinera species are generally large aphids. These soft bodied insects have piercing-sucking mouthparts. Many of the pine aphids tend to be waxy and feed in colonies. They are often found on the bark or underside of branches and twigs or among needles. Feeding damage to mature plants is usually minor, but it can compromise the vigor of small trees. Often the first indication that aphids are present is the large number of yellowjackets that are foraging among the foliage for honeydew. Some of the branches may appear flocked with white waxy material. Infestations are often sudden but brief.
