There are many natural enemies of European corn borer. In controlling this pest Bacillus thuringiensis Bern., Nosema prausta Pil. and Trichogramma spp. are being employed. Trichogramma is the most effective in controlling eggs of European corn borer are infected by parasites of Trichogramma and so population of the pest can be taken under control. Mass production of the parasites in laboratory, especially in some countries of Middle Europe where they give a single generation is grown on hosts like Ephestia spp. and Sitotroga cerealella (Oliver); they are released into fields and population of the European corn borer are taken under control. It was reported that new releasing strategies should be developed and mass production of the parasites must be made in countries where they give more than one generation, so that European corn borer would be taken under control only with the parasites.
