One of nearly 60 species of psyllid in the genus Cacopsylla, this is a minor pest on willow and other ornamental trees.
Generally present in low numbers and not requiring a control effort. Chemical sprays can be effective if they are able to contact the insects, concentrating on the lower surface of the leaves. A systemic such as imidacloprid appears to be effective, moving the active ingredient into the leaf tissue so it is ingested during insect feeding. Neem oil and other tree oils also have given positive results against some psyllid infestations.
