Abstract

A method for mass production of the phytoseiid predator. Phyto­seiulus macropilis (Banks) (Acari : Phytoseiidae) under a net greenhouse was described. About 4 million motile stages of the predator could be obtained when the predator was reared on bean plants, Phaseolus vulgar-is (L.) infested with the two-spotted spider mite, Tetranychus urticae Koch (Acari : Tetranychidae) in a 6.5 x 25 m net greenhouse from late November 2000 to early January 2001. The produced predators were released on several strawberry fields at Ismailia Governorate for control­ling the two-spotted spider mites. The production procedures is de­scribed.
