Oriline products contain the predatory bug Orius, which has a long history of providing effective and reliable thrips control in a range of protected crops. Orius serves as a standard preventive treatment for thrips, particularly Western Flower Thrips, Frankliniella occidentalis.

The Oriline product range consists of three products, each tailored to the country and the use required.

Key Features

  • Orius is the only biological control agent that kills adult thrips.
  • Can kill up to 80 adult thrips per day (while only feeding on a few).
  • Establishes well on pollen-rich crops.
  • Feeding Ephestia eggs (Bug Food E) will enhance the establishment of Orius due to increased fecundity.
  • All five Orius nymph stages are also predatory and adults can fly.
  • Considered a generalist predator it will also feed on mites, moth eggs and other pests.
  • Takes 4 to 8 weeks to establish a population.

Target Pests

  • Western Flower thrips
  • Onion thrips
  • Other thrips spp
  • Moth eggs
  • TSSM (Two Spotted Spider Mite)

How It Works

  • All mobile stages are voracious predators of Western Flower thrips and will attack any developmental stage including adults.
  • Often used in a program with predatory mites in crops such as peppers, where it will quickly establish when feeding on the target pest as well as pollen.
  • Introducing Amblyseius cucumeris or swirskii will control young thrips, and the Orius will complement this by preying on both juvenile and adult thrips.
