Abstract
AbstractIn 1982 and 1983, silhouette traps, sticky traps, and suction traps with and without dry-ice bait were evaluated for sampling populations of black flies that are pests of cattle in central Alberta. The dry-ice-baited silhouette trap was the most effective. The black-fly species collected were Simulium arcticum, S. aureum, S. decorum, S. meridionale, S. tuberosum, S. venustum, S. verecundum, S. vernum, and S. vittatum. Approximately 80% of the black flies collected each year were S. arcticum, the primary pest species of cattle in Alberta.
