Abstract

Shrink wrapping of mangoes, Mangifera indica L., infested with different immature stages of Caribbean fruit fly, Anastrepha suspense (Loew), was tested as a quarantine treatment. Each mango infested with eggs, 1-2-d-old larvae, or mature larvae was wrapped with two layers (one layer, 38.1 μm [1.5 mill thick) heat-shrinkable film. Wrapping for 3 d produced 98.67% mortality of all stages, but 99.9968% mortality (Probit 9) was predicted to require 16.3 d. According to results of previous studies, wrapping mangoes for 16.3 d may lower fruit quality.
