Aphids

Symptoms

Aphids cluster and feed on new growth. Distortion of new growth is often the first noticeable symptom on pittosporum. Aphids have small pear-shaped bodies with paired cornicles. They may or may not have wings. Sooty mold grows on honeydew excreted by the aphids.

COMMENTS on disease

 Aphids are usually most numerous in the spring, but may be present throughout the growing season.

Management

 Aphid “mummies” are a sign that natural biological control is occurring. High aphid populations may be treated with insecticidal soaps, oils, or approved insecticides.
