Orius laevigatus and Orius majusculus are predatory mites used in various crops under glass. They can eat several types of pests: Both nymphs and adult thrips species, aphids, whiteflies, moth eggs, recently hatched caterpillars and even purrs.
In some crops, such as peppers, they settle easily. Rose is apparently less suitable, so Wageningen UR is looking for suitable plants to support the propagation of predatory bugs. A set of fifteen kinds of plants was examined. Both species of Orius find cornflower a good plant to lay their eggs. The sharp pepper 'Black Pearl', which in North America is in great demand with the indigenous Orius, also appears very appropriate. The advantage of this sharp pepper is a compact growth. among other things. The observations are repeated in cages and tested further on a small scale.
