Sevin or malathion should control both insects. Sprays of Orthene will control leafhoppers. Pod gall midge causes unusual reddish galls at the tips of the branches. The galls appear in late spring and may be most common on thornless, seedless cultivars. No chemical control is registered for this pest.
Spider mites cause an autumn like yellowing of the leaves.
Diagnosis of this problem is difficult due to the small size of the insect and leaflets. Scales can usually be controlled by dormant oil sprays applied in spring. Crawlers are controlled with properly timed sprays of Sevin or Orthene. Scale identification aids in proper spray timing. Visuals associated with this text.
