The predatory mite can help to stably reduce the density of Tripidae. It is easy to breed huge amount so the price is less. Moreover, it is possible to release in volume. Before Amblyseius swirskii was developed in early 2000, Predatory mite was important of the natural enemy of Tripidae for biological control like Orius laevigatus.

You can use predatory mite to control palm thrips or western flower thrips on cucumber, green pepper, eggplant, and flowers which are in a greenhouse.
