Evaluation of Predator Mites for Control of Two-Spotted Spider Mites in Carrots Grown for Hybrid Seed in Central Oregon, 2014

Series/Report Number: COARC2014

Abstract: Two-spotted spider mites (TSSM) are an important pest on hybrid carrot seed production in central Oregon. Predator mites have been used to successfully control TSSM in peppermint production in central. This preliminary project was conducted to determine if there is potential for the use of predator mites in carrots. Circumstantial evidence from the results suggests predator mites were successfully established, they were successful in reducing TSSM populations, they were able to effectively disperse throughout the field, predators can be introduced in the fields with moderate amounts of TSSM and they may be able to keep populations at a commercially acceptable level.
