JUNIPER SCALE

Carulapsis juniperi

Juniper scales have white oval

females with a distinct yellow spot

in the center. (See photo) The males are elongated.

All plant parts are attacked, but scales

feeding on the leaves and leaf stems

are noticeable. Loss of vigor and ultimately

plant death can occur. Honeydew produces

will result in sooty mold on the shrubs.

Treatment of heavily infested shrubs

should take place in late spring to early

Summer when the immature crawler

stage is present. They resemble tiny

aphids. The crawlers molt into mature

scales which are harder to manage.

The adult females produce eggs within

Their body and over winter filled with

eggs. Oil sprays in early spring are

effective but may burn the foliage.
