Postharvest insect pest control is highly demanding in agricultural industry including domestic consumer markets and exporting products for a quarantine purpose. Especially, the organic or environmentally friendly agricultural products do not fit to the traditional chemical postharvest treatments using methyl bromide (MeBr) or phosphine (PH3). As an alternative, a physical treatment called CATTS (controlled atmosphere and temperature treatment) has been developed to control various insect and mite pests on ornamental products. The oriental fruit moth, Grapholita molesta, infects the apple or pear fruits and is limited in importing and exporting the infected products. To apply CATTS on this insect pests, the most heat-tolerant stage was determined. Among the immature stages locating on the fruits, the fifth instar larvae were the most tolerant to 44℃ for 20 min. A ramping step of CATTS is to increase chamber temperature from 25℃ to 46℃ under 15% CO2 and less than 1% O2. The ramping rate was positively correlated with the CATTS efficiency. After the ramping step, the duration of CATTS was positively correlated with CATTS efficiency. However, fruit damage by CATTS was negatively correlated with the ramping rate was positively correlated with the CATTS duration. in addition, the CATTS efficiency was highly dependent on the fruit internal temperature at 44℃. From all these parameters, we developed a standard protocol yielding 100% control efficiency of CATTS.
