ABSTRACT
The family Phytoseiidae is the most important family of acarine predators of plant pest mites in agriculture (Huffaker et al. 1969, 1970, McMurtry et al. 1970, Hoy 1982, Helle and Sabelis 1985, Hoffman and Frodsham 1993, Gerson et al. 2003). Relatively little is known about the biology of many of the approximately 2000 named phytoseiid species, because they are not found on agricultural crops. Some phytoseiids are found on crops in single countries, but some premier species are used in integrated mite management (IMM) programs in multiple countries. These include Amblyseius barkeri, A. californicus, A. cucumeris, A. degenerans, A. fallacis, A. hibisci, A. potentillae, A. swirskii, Metaseiulus occidentalis, Phytoseiulus persimilis, and Typhlodromus pyri (see Figures S12.1 to S12.4 on the CD).
