Abstract: Development, reproduction, and life table parameters of the phytoseiid mite Neoseiulus idaeus Denmark & Muma preying on various stages of Tetranychus urticae Koch fed on papaya or snap bean plant were studied at 25 ± 2°C, 77 ± 2% RH and 12L:12D photoperiod. Most characteristics of the predator, including the duration of the immature stages, preoviposition and oviposition periods, and female longevity did not differ significantly among the different food combinations. During the adult stage, N. idaeus females survived up to 14 days. The net reproductive rate, the mean generation time, and the intrinsic rate of natural increase of N. idaeus were very similar on all T. urticae stage – host plant combinations, ranging from 5.15 to 6.61 females, 10.15 to 12.62 days, and 0.150 to 0.168, respectively. These results indicate that T. urticae reared either on papaya or snap bean is an adequate prey for the development and reproduction of N. idaeus. Moreover, the current findings demonstrate that the host plant of T. urticae did not affect the predator. The implications of these results for the success of N. idaeus as a biological control agent of T. urticae in papaya orchards are discussed.
