Résumé

In laboratory experiments, refrigerated (2 deg C) controlled atmospheres significantly increased the mortality of green peach aphids (Myzus persicae) and western flower thrips (Frankliniella occidentalis) compared with refrigerated storage in air. However, insect mortality during marine shipment in mixed-load containers at 0.5 deg C was not significantly increased by controlled atmosphere. In laboratory experiments, mortality of green peach aphids ranged from 32.8% in the refrigerated control to 96.8% after storage in 0.10% O2 for 4 days followed by 7 days in 3% O2 + 5% CO2. When stored under these same conditions, western flowers thrips mortality was 71% compared to 16% mortality in the refrigerated air-stored control. Following an 11-day marine shipment from California to Guam in a controlled-atmopshere, vase life was extended for most of the 20 Californian cut-flower and foliage products on board compared with those shipped under control refrigerated air conditions.
