Evaluation of sticky traps for collecting face flies (Diptera: Muscidae) from different locations in an irrigated pasture
Environmental Entomology 16 (1), 190-194
Abstract: Four sticky-trap designs were evaluated for their effectiveness in capturing the face fly, Musca autumnalis De Geer, from three different locations in an irrigated pasture. The trap site where most flies were collected (67%) was near resting cattle. Fly collections from open pasture and areas bordered by trees represented 20 and 13%, respectively, of the season total. Pyramid traps, when placed at each of the three locations, captured significantly more male and female flies per unit time than did a cylinder, square panel, or blood board. Catches on the cylinder and square panel were not significantly different. The blood board captured the fewest flies of either sex. The pyramid also captured significantly more female flies per unit surface area when placed near areas where cattle rested. Physiological age of trapped female flies was determined for each location and trap design. Nearly equal numbers of nulliparous and uniparous flies were captured on both pyramid and square-panel traps placed where cattle rested. At that site, uniparous flies outnumbered nulliparous flies by nearly 2:1 when captured on the cylinder design. Pyramid traps captured 80% (117 of 146) of gravid flies (nulliparous, uniparous, and biparous+) trapped during the study. The pyramid trap was also useful in assessing incidence of the nematode, Heterotylenchus autumnalis Nickle, and reproductive diapausing face fly females.
