Calculation of Survival from Double Hot-water Immersion Treatment for Papayas Infested with Oriental Fruit Flies (Diptera: Tephritidae)

Abstract
Papaya fruits infested with eggs of the oriental fruit fly, Dacus dorsalis Hendel, were exposed to a variety of double hot-water immersion treatments, and larval survival rates were measured. Using measurements of egg number as a function of fruit depth, a mathematical model was developed to calculate survival rates. Predictions compared favorably with the experimental results.
