Effects of cobalt gamma radiation on San Jose scale (Homoptera: Diaspididae) survival on apples in cold and controlled-atmosphere storage.

摘要: ‘Red Delicious’ apples ( Malus pumila (Mill.)) infested with San Jose scale, Quadraspidiotus perniciosus (Comstock), harvested from commercial and experimental orchards were subjected to cobalt-60 gamma radiation then stored in either regular cold storage, controlled-atmosphere or at room temperature. Scale survival measured various intervals after treatment declined time the magnitude of dose received. Survival was not influenced by method storage.
