Abstract
Laboratory studies were done to compare the effect of two cold storage conditions on longevity and fecundity of two anthocorids, Orius majus culus (Reuter) and Orius laevigatus (Fieber). Survival of adults is be tter at a thermoperiodic condition of 13-degrees-C/3-degrees-C than at a constant temperature of 9-degrees-C. Female longevity decreases as the duration of exposure to cold conditions increases. Fecundity of O. laevigatus is not significantly reduced after 50 days of exposure to thermoperiodic conditions even though those of O. majusculus is strong ly reduced after 20 days.
