Abstract

Natural infestations of the two-spotted spider mite were controlled on green house cucumber by early releases of the predatory mite, <i>Phytoseiulus persimilis</i> Athias-Henriot. Later sporadic mite outbreaks severely damaged some plants and required frequent surveys and repeated predator releases in the greenhouse. However, no mite sprays were required and crop yield was satisfactory.
