Abstract
Two preliminary methods are described for mass production of the predatory mite, Phytoselulus macropilis (Banks) under the conditions of two net plastic greenhouses (500 holes/inch2 and of 40 m2 each). The predator was reared on the two-spotted spider mite, Tetranychus unicae Koch, infesting bean plants grown in trays or in the greenhouse soil. The produced predators varied during different seasons. The highest predator production obtained during spring & autumn (moderate temperatures) as the average yields of P. macropilis were 1,881,600 and 1,528,800 predator individualss 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, while low numbers were obtained during winter months due to the prevailing low temperatures and shortage of the food supply, T. urticao.
