The effect of peach [Prunus persica (L.) Batsch] extrafloral nectaries on natural enemies and herbivores was investigated. One-year-old ‘Lovell’ seedlings with and without extrafloral nectaries were planted in replicated orchard plots in Maryland and West Virginia. Herbivore and natural enemy colonization, biological control, and tree herbivory were measured through the growing season. Preliminary data indicate that extrafloral nectaries play an important role in the peach-herbivore-natural enemy system.
