White sapote, Casimiroa edulis Llave & Lex., was subjected to three quarantine treatments known to kill immature Caribbean fruit fly, Anastrepha suspense (Loew), in other fruits. Cold storage at 1 or 3°C for 15 and 18 d, respectively, did not cause appreciable harm to white sapotes compared with fruits stored at the normal 7°C. Immersion of white sapotes in water at 43.3°C for 90 or 120 min or at 46°C for 60 or 90 min caused considerable pitting and decay and interfered with ripening. Fumigation with methyl bromide at 24 and 40 g/m3 (24 ± l.O°C) gave a reddish hue to white sapote, interfered with ripening, and increased the rate of decay. Cold storage at 1°C for 2-12 d was examined for its effectiveness in killing Caribbean fruit fly immatures in white sapote. Dose-mortality data were analyzed using the normal, logistic, and Gompertz probability density functions (PDF). The logistic PDF gave unrealistically low estimates of probit 9 (99.9968%) mortality; estimates using Gompertz, log 10, seemed too high. The normal PDF and Gompertz, non log 10, gave reasonable estimates of probit 9.
