Abstract

Ten predaceous mite species, belonging to eight families (Ascidae, Bdellidae, Caligonellidae, Camerobiidae,
Cheyletidae, Cunaxidae, Phytoseiidae and Stigmaeidae), were collected from fruit and timber trees in Riyadh, Saudi
Arabia. Out of these ten species, six (Arctoseius cetratus (Sellnick), Decaphyllobius gersoni Bollan_d, Molothrognathus
sp., Neoseiulus barkeri Hughes, Neoseiulus mumae(Shehata & Zaher), and Scutascirus factus Chaudhari) are fristly
rcorded in Saudi Arabia. In addition, Agistemus vulgaris Soliman & Gomaa, Euseius scutalis (Athias- Henriot), and
Spinibdella bifurcata Atyeo are reported for the first time on fruit trees in Saudi Arabia, while Hemicheyletia bakeri
(Ehara) was previously recorded on pin timber trees. Some of these predaceous mites, recorded in this study, can be
used as biological agents against phytophagous mites in Saudi Arabia.
