Abstract:

Temperature and exposure times necessary to kill eggs of Fuller rose beetle, Asynonychus godmani Crotch, with hot-water immersion were determined and fitted to a mathematical model. The temperature rise beneath the calyx of lemons was also modeled during hot-water immersion. From these two models, a final model was developed to estimate the immersion time needed to kill eggs deposited beneath the calyx using 52 water, and infested lemons were treated to validate the model. Egg mortality exceeded the predicted mortality. There were no survivors among 4,071 eggs infesting lemons when they were immersed for 8 min at 52.
