Popis:	Western cherry fruit fly (WCFF), Rhagoletis indifferens Curran, infests cherries in the northwestern United States. Exposure of naturally infested fruit to doses from 42 to 210 Gray (Gy) reduced pupation; only one adult emerged (at 127 Gy). In a second test in which fruit were exposed to from 4.4 to 106 Gy, no adults emerged following irradiation of field-infested fruit at ≥17.6 Gy. When > 124,000 naturally infested cherries were exposed to 97 Gy, gamma irradiation was an efficacious quarantine treatment. No normal adults and only one abnormal adult with vestigial wings emerged from a treated population estimated to be 84,369 WCFF larvae. This research demonstrated that irradiation would be a potential quarantine treatment for WCFF larvae in cherries. Parasites, Pachycrepoideus vindemiae (Rondani), emerged from many of the untreated puparia but not from those WCFF irradiated as larvae.
