CATTS (controlled atmosphere/temperature treatment system): A novel tool for the development of quarantine treatments

Abstract

Controlled atmosphere (1.0% O2, 15% CO2) in combination with high temperature (45 and 47°C) was compared with high temperature alone to determine the impact of combination heat and controlled atmosphere treatments on mortality of 5th instars of codling moth, Cydia pomonella (L.), in sweet cherries. The combined treatment unit is termed CAITS for Controlled Atmosphere/Temperature Treatment System. LT99s at 45 and 47°c were 64 and 44 min, respectively, for the combined treatments and 124 and 72 min, respectively, for high temperature alone. This research demonstrates the potential effectiveness of controlled atmosphere in combination with high temperatures as a quarantine treatment against codling moth larvae in sweet cherries.
