title: Evaluation of ammonia, human sweat, and bovine blood as attractants for the female canyon fly, Fannia conspicua (Diptera: Muscidae), in southern California.
abstract: Human sweat, liquid ammonia, and bovine blood are known to be attractive to some hematophagous flies. These materials were evaluated with and without carbon dioxide (CO(2)) for their ability to increase capture of female "canyon flies" (Fannia conspicua Malloch) using CDC-type suction traps (without light). Ammonia acted synergistically with CO(2) to increase trap catch 89.9% over CO(2) alone. There was no synergistic effect of human sweat or bovine blood with CO(2). In the absence of CO(2), none of the three materials increased trap catch of female canyon flies relative to non-baited traps. Implications for canyon fly control and further trap improvement are discussed.
