Research on natural enemies of <em>Bemisia tabaci</em> was conducted in the chili pepper fields in Sub-district of Pakem, District of Sleman, The Special Province of Yogyakarta during the dry season of May-October 2009. The aims of this research were to study the diversity and abundance of parasitoid and predator species associated with <em>B. tabaci.</em> Samplings of insect species were done using yellow pan trap, sweep net, direct observation of insects colonized young leaves, and collection of nymphs for <em>B. tabaci.</em> Measurement of insect diversity was calculated using Shannon’s index diversity and Evenness index. Nine species of insect predator were identified, i.e. <em>Harmonia octomaculata</em> (Fabricius), <em>Menochilus sexmaculata</em> (Fabricius), <em>Scymnus</em> sp., <em>Micraspis inops</em> Mulsant, <em>Coccinella</em> sp. (Coleoptera: Coccinellidae), <em>Paederus fuscipes</em> Curtis (Coleoptera: Staphylinidae),<em> Orius</em> sp. (Hemiptera: Anthocoridae), <em>Linyphiidae</em> sp.1 (Araneae), and <em>Syrphidae</em> sp.1 (Diptera). <em>Eretmocerus</em> sp. (Hymenoptera: Aphelinidae) was the only parasitoid found in the nymphs <em>B. tabaci</em> collected and has the potential to control <em>B. tabaci</em> in the red pepper fields.
