Product description


Dicyphus hesperus is a generalist predator who feeds on whiteflies, 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.

Adults and nymphs 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 hesperus should not be used on its own to replace other biological control agents.

Adults are able to fly. The female lays her eggs inside plant tissue. Nymphs look like the adults, but they are smaller and their wings are not developed.

Targeted crops

  • Market garden crops:
    • Cucumbers
    • Eggplants,
    • Peppers
    • Tomatoes, etc.
  • Ornamental plants:
    • Tropicals and semi-tropicals

Targeted pests

  • Aphids
  • Moth eggs
  • Spider mite
  • Thrips
  • Whiteflies


Application Instructions

To combat whitefly infestations, we propose releasing groups of 100 adults into targeted areas or the addition of a weekly supply of frozen moth eggs to feed these adult populations. To reproduce, Dicyphus requires a plentiful food source – ideally over one hundred prey. As this predator mainly obtains its water supply from plant feeding and can persist without sustenance for an extended time period, releases should only occur in locations where pests have been identified or extra nourishment is being provided.

Mullein banker plants offer the dual benefit of increasing beneficial insect populations and providing an effective method for early detection of crop-damaging pests.
