Mass production of natural enemies started in the 1940s and quickly developed thereafter. These developments were mainly triggered by trying to economize rearing and making biological control more competitive when compared with other pest-control methods. Storage of natural enemies is only possible for very short periods, with the exception of species for which it is known how to start and terminate diapause. Initially, the collection, shipment and release of biological control agents were rather amateurish, but enormous progress has also been made in this area. Many natural-enemy species can now be produced at competitive costs, resulting in increased use of biological pest control.
