We studied the feeding ability and functional response of adult females of the predatory mite Neoseiulus californicus (McGregor) on greenhouse thrips. The females could attack 1 st instar larvae of Frankliniella occidentalis, but not 2 nd instar larvae, pupae, or adult females. The numbers of 1 st instar larvae of F. occidentalis, Thrips palmi, and Frankliniella intonsa consumed by the predatory mite increased as the prey density increased. The mean maximum predation rates per day against 1 st instar larvae were 7.1 F. occidentalis, 6.9 T. palmi and 3.1 F. intonsa. These result suggest that N. californicus is an effective natural enemy of these thrips.
