Abstract: Distribution of Mediterranean fruit fly, Ceratitis capitat (Wiedemann), throughout west Oahu was determined from trap and fruit infestation data. The range of C. capitata is wider than previously reported and includes four of the five major vegetation zones. No flies were captured in native forests. From November 1985 to October 1986, 96.2% of the traps in xerotropical habitats and 61.5% of the traps in pluviotropical habitats call-in flies. During the 12 month study 90.4% of the total flies captured were recovered in 5 traps (total traps = 52) located in or near feral coffee, Coffea arabica I.., in Makaha and Waianae Valleys. C. capitata occurred at low densities throughout the year along most of the coastline where residential back yard hosts were infested and sporadically throughout gulches and uplands of the Waianae Mountain Range where common guava, Psidium guajava I... and strawberry guava. Psidium cattleianum Sabine, were infested. The most important hosts were coffee; false kamani, Terminalia catappa L.; mock orange, Murraya exotica I..; citrus, Citrus spp.; common guava and strawberry guava. Coffee produced as many as 234 flies per kg, while all other host fruits produced low numbers. Findings are discussed with respect to development of eradication strategies for C. capitata in Hawaii.
