The effect of insect populations on sour cherries in the absence of insecticide sprays was studied in a Montmorency cherry orchard from 1959 through 1962. Fruit from trees sprayed only with a fungicide (dodine) was examined for insect injury at harvest. Results for 1961 and 1962 are given in detail. Seventeen percent were injured in 1961 and 20% in 1962 with the plum curculio, Conotrachelus nenuphar (Herbst), causing 14 and 17%, respectively. The remaining 3% injury was due primarily to lepidopterous larvae, including internal injury by the cherry fruitworm, Grapholitha packardi Zeller, and the destructive pruneworm, Mineola scitulella Hulst, and external feeding by the eye-spotted bud moth, Spilonota ocellana (Denis & Schiffermüller), and fruit-tree leaf roller, Archips argyrospilus (Walker), The plum curculio was responsible for additional losses of 9 and 6% owing to fruit “drop” prior to harvest in 1961 and 1962, respectively. The total crop loss caused by insect injury was 26%.
