摘要:

Dry heat is proposed as a non-chemical postharvest disinfestation treatment for export persimmons (Diospyros kakiL.). A fruit surface temperature of 47°C at 55–60% RH for 15 min is recommended to effect 100% mortality of thrips, mealybugs, and leafrollers. On persimmon fruit these are all surface dwelling pests. Fruit tolerance trials showed that this fruit surface temperature/time exposure was not detrimental to persimmon fruit firmness, soluble solids concentration, and appearance; and did not reduce shelf life. A commercial scale confirmatory trial is planned.
