A field survey on the island of Molokai was conducted to determine the infestation rates of oriental fruit fly (Bactrocera dorsalis Hendel) in two Solo varieties of papaya (Carica papaya L.), ‘Kapoho’ and ‘Sunrise’, based on varying levels of visual and “hot spot” colorimetric b indices of fruit ripeness. Oriental fruit fly infestations were found in all stages of Kapoho Solo fruits. The infestation rate ranged from 2 to 50 % in mature green to fully ripe fruits. Mature green and quarter ripe (b < 30) Sunrise Solo papayas were found free of oriental fruit fly infestation. Laboratory trials were followed to determine the host status of the four ripeness stages in the two varieties.
