Dicyphus hesperus is a generalist predator who feeds on whitesflies, thrips, aphids, moth eggs and other pests. This predator is able to establish itself in greenhouses, keeping constant pressure on pest populations. Dicyphus is used successfully in several greenhouses in North America.
Adult and nymph are predator and very effective to control several species of whiteflies and thrips in tropical and semi-tropical ornamental crops. Because it is also a plant feeder, Dicyphus should not be used on its own to replace other biological control agents.
Adult has elongated shape (6 mm) and has large red eyes. The body is green and black with mottled semi-transparent. Adults Dicyphus are able to fly. The female lays her eggs inside plant tissue. Nymphs look like the adults, but they are smaller and, in the early stages, totally green. their wings are not developed.
