Research Reports: Gamma Irradiation Followed by Cold Storage as a Quarantine Treatment for Florida Grapefruit Infested with Caribbean Fruit Fly
Abstract
`Marsh' white grapefruit, Citrus paradisi (Macf.). infested with eggs and larvae of Caribbean fruit fly, Anastrepha suspensa (Loew) were subjected to ionizing radiation at several low doses followed by cold (1.1@*C) storage for 0 to 8 days. Data analyses indicated that an irradiation dose of 50 Gray followed by 5 days of cold storage will give in excess of probit 9 level of quarantine security. A test involving more than 100,000 insects infesting grapefruit confirmed the efficacy of this treatment.Downloads
