Aucuba (Aucuba japonica)-Aphid

Foxglove aphid (Aulacorthum solani) and others

Pest description and damage The foxglove aphid has been reported on aucuba. This aphid is pale green with dark green patches at the base of each cornicle. The antennae are banded black and pale green. Clusters of green aphids feed on the undersides of leaves making them difficult to detect. Leaves may pucker in response to aphid feeding and sooty mold develops on underlying leaves.

Biology and life history This is an aphid that thrives in the cool of winter. As the weather warms in spring, winged forms are produced and the aphid flies to any of its many alternate hosts.

Pest monitoring Watch for the first signs of honeydew as you pass by plants. Yellow sticky traps may catch incoming aphids, and water sensitive paper are used for monitoring honeydew.
