Subjecting carambolas, Averrhoa carambola L., infested with Caribbean fruit fly, Anastrepha suspense (Loew), larvae to vapor heat (saturated hot air) at 46-46.3 (air speed of 1.0-1.1 m/s) for 90 min followed by cooling in relatively still air at ˜23 ± 0.5OC provided probit 9 security (99.9968% mortality) with 95% confidence. When mfested carambolas were exposed to vapor heat at 46-46.3 for 90 min and then immediately immersed in 13 ± O.2°e water for 1 h, 3 of an estimated larval population of 45,856 survived, indicating that rapid cooling of the fruit reduced larval mortality. Vapor-heat treatment of carambolas at 49-49.SoC for 45 or 60 min damaged the fruits. Shelf life and color quality of carambolas treated with vapor heat at 4S.S-4S.6"C for 90 or 120 min or 46-46.3 for 60 or 90 min were not significantly reduced compared with controls.
