Abstract
Two preliminary methods for mass production of the predatory mite, Phytoseiulus macropilis (Banks) under the conditions of two net plastic greenhouse (500 mesh/inch2 and of 4 m2 each) are described. The predator was reared on the two-spotted spider mite, Tetranychus urticae Koch, feeding on bean plants grown in trays or in the greenhouse soil. The highest predator production obtained during spring and autumn (moderate temperature) as the average yields of P. macropilis were 1.080.600 and 1.528.800 predator individuals in bean plots, while they were 1.080.000 and 720.000 predators on bean trays in the two previous seasons, respectively. Moderate predator yields were collected during summer months due to prevailing high temperatures and the least number was obtained during winter months due to the prevailing low temperatures and shortage of food (T. urticae) supply.
