Effect of cold treatment on survival and development of codling moth (Lepidoptera: Tortricidae) in cherry.

'Bing' cherries, Prunus avium, were obtained from an organic orchard and a conventional commercial orchard. The two groups were examined separately in replicated tests infested with each fruit initially infested with a first-instar codling moth, Cydia pomonella. To simulate commercial postharvest holding conditions, the treatments were 0 (control), 1, 2, 4, 7, 10 and 14 day-cold storage at 3.3 deg C. The fruits were examined three or more times to determine larval survival, life stage, fruit condition and fungal disease. Survival of first instars was affected only by cold storage durations of more than or equal to 7 days. When infested with codling moth larvae, both organic and conventionally grown cherries quickly deteriorated from fungal diseases. The rate of moth development was estimated from the surviving larvae and was significantly different between organic and conventionally grown cherries for all instars except the second.
