About beneficials Home > Pest management > beneficials Resident beneficial organisms (or natural enemies) can enhance control of many pest arthropods, often providing good suppression of many indirect pests (aphids, mites, and leafminers). The best way to conserve these beneficials is to use caution when selecting insecticides and timing applications. Beneficials are often more susceptible to broad-spectrum insecticides (organophosphates, carbamates and pyrethroids) than are the pests they attack. The availability of flowering plants within the orchard can also help conserve beneficials, since the adult stage of many predators and parasites feeds on nectar and pollen.
