Post-harvest control of Quadraspidiotus perniciosus on stored apples
In Canada investigations were carried out to study the post-harvest control of Quadraspidiotus perniciosus (EPPO A2 quarantine pest) in stored apples by subjecting the infested apples to controlled atmospheres. Infested fruits were stored in a regular controlled atmosphere (2.6-3.0% O2 ; 2.4-2.5% CO2) and in a low-oxygen controlled atmosphere (1.5-1.7% O2 ; 1.0-1.1% CO2) at 1ø or 3ø C for 31-34 weeks, plus an additional week at 20ø C and 50-60% relative humidity. In both treatments, San Jose scale was completely eliminated from infested fruits.
