Abstract:Hot-water immersion was tested as a potential commodity treatment for guavas infested with third instars of the Caribbean fruit fly, Anastrepha suspensa (Loew). Infested guavas were immersed in water at 46.1 ± 0.5°C for various time periods. Probit 9 (99.9968%) mortality was estimated to occur at 32.7 min. A large-scale test with 2,450 guavas containing an estimated 181,556 larvae treated for 35 min at 46.1 ± 0.5°C produced no survivors. Hydrocooling guavas immediately after hot-water treatment until fruit center temperatures returned to 24 ± 2°C did not significantly affect mortality. Guavas tolerated 35 min at 46.1 ± 0.5°C with only slight reduction in quality. Treated guavas held at 10 ± O.soC maintained acceptable quality 7 d longer than guavas held at 24 ± 2°C.
