Orius insidiosus
Description
Orius insidiosus is a generalist predator that can feed on many species of small, soft-bodied insects like thrips, mites, aphids, small caterpillars and pollen. It has been shown to be an effective control for western flower thrips in cucumber and sweet pepper greenhouses.
Orius insidiosus a small predatory pirate bug, 2-2.5 mm long, belonging to the Anthocoridae family. It is black with light brown spots on its back. The nymphs look like the adults, but are dark orange and 0.5 to 1.8 mm long.
The adults and nymphs are highly voracious generalist predators. All stages of Orius move very quickly. The adults are good flyers and move efficiently throughout a greenhouse to locate prey. Adults are attracted to and often found in flowers. If prey is abundant, Orius kills more thrips than it needs to survive. The presence of pollen favors development of Orius as it acts as an alternate food source. It can be used in combination with Neoseiulus cucumeris or Amblyseius swriskii
