Survival of short-term exposure to high temperatures was determined for the eggs and first through fifth instars of oriental fruit moth, Grapholita molesta (Busck). LT50's and the temperatures and exposure times required for 100% mortality are reported. First instars were most susceptible and fifth instars were least susceptible to high temperatures. Less time was required to reduce survival of younger than older larvae at the same temperature. A 1.0°C increase in temperature resulted in shorter exposure times to reduce survival of any immature stage. Response of wild larvae was similar to that of laboratory-reared individuals. A heat treatment of 45.0°C for 55 min was sufficient to kill all immature stages. About 39 min was required for the interior of a nectarine to reach 45.0°C. Techniques to test insect response to high temperature and use of heat treatments for disinfestation of stone fruits are discussed.
