Abstract: The two predatory mites , Neoseiulus ( Amblyseius ) californycus (McGregor ) and Phytoseiulus macropilis ( Banks ) were mass reared in the laboratory on mulberry leaf arenas infested with the two-spotted spider mite as animal diet and pollen as plant diet. Both predators were successfully maintained and mass reared on the two-spotted spider mites . The rate of increase of N.californicus on the two-spotted spider mite were 8.1 ,12.0 and 23.5 fold after 6 ,12 and 15 days, respectively . While that of P. macropilis they were 17.9 ,33.6 and 53.1 fold . Pollen of apricot , palm , peach and apple were unsuitable for rearing the predatory mite , P. macropilis , but proved to be suitable for the predatory mite , N. californycus . However , the rate of the predator increase were comparatively low when compared with rearing on the two-spotted spider mite ,Tetranychus urticae Koch . They were 1.2 , 3.6 , 1.5 and 1.8 fold after 15 days when reared on pollen of apricot , palm , peach and apple , respectively .
