In a faunal study of whiteflies predators in 1999-2003 at different areas of Mazandaran and Golestan provinces, 64 species of Hexapoda and Acarina were collected and identified. The species were confirmed by the authorized specialists. All mites belonged to Phytoseiidae of Mesostigmata, and the predatory insects Coleoptera, Hemiptera, Neuroptera, Diptera, and Thysanoptera. The predator beetles that belonged to Coccinellidae, contain 25 species, and for Hemiptera, Neuroptera, Diptera, and Thysanoptera were 21, 3, 5 and 4 species, respectively. Among the identified predators, 4 species of Hemiptera including: Anthocoris confusus Reuter, Anthocoris flavipes Reuter (Anthocoridae), Geocoris marduk Linnavuori, and Geocoris ningal Linnavuori(Lygaeidae), and also Diplosis aphidisuga (Diptera: Cecidomyiidae) are new record from Iran. In this study, feeding efficiency of predators was also determined on the different life stage of Bemisia tabaci Gennadius in laboratory conditions. The results of feeding tests indicated that among the different predators, Chrysaperla carnea(Stephens), Coccinella septempunctata (L.), Acletoxenus formosus Loew, and Nabis palifer Seidenstucker with 72.1±37.5, 68.2±55.4 and 56.1±46.9 fed preys had the most feeding efficiency, respectively.
