Control of the Caribbean fruit fly in Florida grapefruit by phosphine fumigation (Anastrepha suspensa, commodity treatment, quarantine, Citrus paradisi, quality)
Grapefruit, Citrus paradisi Macf., infested with the Caribbean fruit fly, Anastrepha suspensa (Loew), were fumigated with phosphine (PH3) beneath a covering. After fumigation, fly-infested and control fruit were held at optimun cold-storage conditions. Yield of insects from fumigated fruit was compared to that of untreated fruit to determine the efficacy of the treatment. Insects survived fumigation when treatment times were too short under low temperatures, or when dose rates were too low under ambient temperatures. Phytotoxicity tests with fumigation treatments sufficient to prevent insect survival indicated rind injury after 4 wk of optimum storage conditions. Injury was manifested as scald and rind breakdown that included aging and pitting. When removed from storage and held at room temperature, fruit with visible injury often decayed.
