SORBUS INSECT PROBLEMS
Aphids cause distorted growth and deposits of honeydew on
leaves.
Mountain ash sawfly larvae are light green with black dots
and tend to feed in groups. The insects curl the back of
their bodies around the stems as they feed.
Scales of various types can usually be controlled with
sprays of dormant oil applied in the spring.
