What's eating my nanking cherry?
Plum curculio (Conotrachelus nenuphar)

Control: Shake branches over a tarp at petal fall to knock off adults; apply kaolin clay; remove infested dropped fruit promptly.
Cherry fruit fly (Rhagoletis cingulata)

Control: Hang yellow sticky traps with ammonium acetate attractant from late spring; apply spinosad spray timed to adult emergence; harvest promptly.
Aphids
Signs: Curled, sticky leaves on shoot tips; heavy infestations weaken new growth.
Control: Knock off with a water jet; insecticidal soap; attract hoverflies with companion flowering herbs.
