Morgan, C.V.G. 1967 Fate of the San Jose scale and the European fruit scale (Homoptera: Diaspididae) on apples and prunes held in standard cold storage and controlled atmosphere storage.. Canadian Entomologist 99: 650-659.
Notes: The San José scale, Aspidiotus perniciosus Comstock, died within 84 to 140 days on Winesap apples harvested in early October and placed in standard cold storage or controlled atmosphere storage under laboratory or commercial conditions. The scale died more quickly in controlled atmosphere storage than in standard cold storage. The black caps of the first instar stage were the most resistant to mortality factors in cold storage. It is suggested that Winesap apples infested with the San José scale can be given an inspection certificate for export that guarantees freedom from live scale if the fruit has been stored for specified periods. The San José scale die with in 34 days on Italian prunes when the harvested fruit was kept in standard cold storage. A complete mortality of the European fruit scale, Aspidiotus ostreaeformis Curtis, on Hyslop crab, McIntosh, or Newtown apples, could not be obtained in any type of storage.
