Abstract

A method that induces diapause, originally developed for individually reared codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae), was tested on the open tray, sawdust-based diet system used in Canada for mass-rearing. The efficiency of the standard and diapause rearing systems are compared and the quality of the adults reared from the two systems is discussed. The benefits and economics of rearing and storing CM larvae in diapause are discussed and related to the ongoing CM eradication program.

Key words: Cydia pomonella; mass-rearing; diapause; insect quality; storing
