Summary

Combined heat treatments and cold storage have potential as a quarantine treatment for 5th-instar larvae of Cydia pomonella. Larvae were subjected to heat treatments of 43, 44 or 45 deg C for 30 minutes, followed by cold storage at 5 or 0 deg C for up to 28 days. Combinations of these treatments increased larval mortality compared with either treatment alone. Mortality increased with increasing intensity of heat treatment and duration of cold storage. Combination treatments could be effective in commodities, such as apples and pears, which can endure short periods of heat stress and prolonged cold storage.
