The Insect Rearing Management (IRM) system was used to rear the black lyre leafroller, Cnephasia jactatana (Walker) (Lepidoptera: Tortricidae). The results obtained include life cycle development at various temperatures, application of “day-degrees” in manipulating the life cycle, and use of low temperature for storage of life stages. IRM is a valuable system for regulating production of different life stages as it produces insects of specified quality as required. IRM can be adapted for rearing facilities which handle multiple-species rearing.
