The suppressive biological control of mites on oilseeds can be successful under the circumstances of the ratio of prey and predators being I : 20 to 1 : 50 and the original infestation not being higher than 500 specimens per 1 kg. Preventive biological control was carried out in empty oilseed stores after they were cleared. The predators which were released in the stores 2000 specimen s being evenly distributed over an area of 100 m2 were successful and suppress the population of acaroid mites.
