We conducted a statewide field census of arthropod fauna in beef cattle pastures and rangeland during 2006 and 2007, covering six counties. Several sampling techniques were utilized: sweep nets, sticky cards, sticky stable fly traps, baited dung beetle traps, pitfall traps, wet fly traps, yellow jacket traps, aged dung samples, pane traps, mosquito traps, and aerial nets. The sticky traps, wet fly traps, and aged dung samples proved to be the best for trapping the pest and beneficial species of interest. Pest Diptera found frequently in our traps were face flies and stable flies (both Muscidae), black flies (Simuliidae), and biting midges (Ceratopogonidae). Very few horn flies (Muscidae) were found in our traps because they spend most of their life on the bovine hide. So far, three dung-inhabiting beneficial Coleopteran families have been found in our traps: Scarabaeidae, Hydrophilidae, and Staphylinidae. Identification and relative frequency of taxa collected with each method will be presented.
Species 1: Diptera Muscidae Muscaautumnalis (face fly) Species 2: Diptera Muscidae Stomoxyscalcitrans (stable fly)
