Three predominant and economically important shrubs of the sagebrush-grass range community in Utah, namely big sagebrush (Artemisia tridentata Nutt.), rubber rabbitbrush (Chrysothamnus nauseosus (Pall.) Britt.), antelope bitterbrush (Purshia tridentata (Pursh) DC), and a widely re-seeded range grass, crested wheatgrass (Agropyron cristatum (L.) Gaertn.) were sampled during the summers of 1966 and 1967, and yielded twenty species of thrips. Three species (Anaphothrips tricolor Moulton, Chirothrips aculeatus Bagnall, Chirothrips simplex Hood) were new distributional records for Utah. Seven species (Frankliniella n. sp. #1, Frankliniella n. sp. #2, Haplothrips n. sp., Leptothrips n. sp., Oedaleothrips n. sp., Sericothrips n. sp. #1, Sericothrips n. sp. #2) were undescribed. Six species (Anaphothrips zeae (Moulton), Aptinothrips rufus (Gmelin), Chirothrips aculeatus Bagnall, Frankliniella minuta Moulton, Frankliniella occidentalis (Pergande), Thrips tabaci (Lindeman) had previously been reported as injurious to various range and agricultural hosts. The remaining species included: Aeolothrips duvali Moulton, Aeolothrips fuscus Watson, Aptinothrips rufus stylifera Trybom, Haplothrips sonorensis Stannard, and Rhopalandrothrips corni Moulton. Host preference, habitat preferences, and peaks in seasonal abundance were determined for each thrips whenever possible.
