“…The 12 traps set at Hay River over about 6 ha captured 153 629 tabanids in 20 days (1143 flies/trap/day baited, 688 flies/trap/day unbaited). By comparison, mean catches with traditional traps at latitudes of 55–59°N in Canada have been much lower, at, for example, five flies/trap/day in a Malaise trap (Maire, 1984a), six flies/trap/day in a Malaise trap (Maire, 1984b), 32 flies/trap/day in a Malaise trap (Baribeau & Maire, 1983b), ≥33 flies/trap/day in a Manitoba trap (McElligott & Galloway, 1991), 36 flies/trap/day in a canopy trap (Maire, 1984a), and 101 flies/trap/day in Malaise and canopy traps (McElligott & Lewis, 1998).…”

Baits for tabanids (Diptera: Tabanidae) were tested in the Northwest Territories (60 °N) and Ontario (45 °N) using Nzi traps. Tests targeted ammonia, phenols/cow urine and octenol. About 200 000 tabanids were captured in 15 experiments with a maximum capture of 4182 in one trap in 1 day. In the Northwest Territories, phenols, urine and octenol were effective single baits for only some species. At both locations, adding ammonia to an unbaited or an octenol-baited trap had no effect on catches. By contrast, catches were increased for several species when ammonia was combined with phenols or urine. In Ontario, including ammonia in various baits increased catches by 1.5- to 3.4-fold relative to octenol alone for three Hybomitra and one Tabanus species. Synergism between ammonia and phenols was clearly demonstrated for the dominant Hybomitra species in Ontario (Hybomitra lasiophthalma), but not for the dominant species in the Northwest Territories (Hybomitra epistates). In five other northern Hybomitra species, baits of ammonia and/or octenol in combination with phenols resulted in a 1.7- to 4.1-fold increase in catch relative to an unbaited trap. Further tests of ammonia as a synergist for biting flies may prove useful in, for example, tsetse, which respond strongly to phenols.

During the summers of 1990 and 1991, 406 larval tabanids were extracted from samples of peat collected at eight sites in a subarctic Labrador peatland. Although not all larvae could be identified to species, five deer fly (Chrysops spp.) and six horse fly species (five Hybomitra spp., one Atylotus sp.) were identified. Chrysops probably zinzalus and Chrysops nigripes were the dominant deer fly species and Hybomitra arpadi was the most commonly collected horse fly. Deer fly larvae accounted for 88% of specimens collected. Chrysops larvae were collected most frequently from sites where the water table was at or below the substrate surface, and were rarely observed at sites where the substrate was submerged. The opposite was true for horse fly larvae, which were commonest at sites where the substrate was submerged. The density of tabanid larvae in the peatland was 14.04/m2 in regions of the fen where the water table was 3–5 cm below the substrate surface, 23.20/m2 in regions where the water table was at or slightly below the substrate surface, and 2.20/m2 in regions where the substrate was submerged. Tabanid pupae and pupal exuviae were collected from moss hummocks in the peatland.

Development of larvae of Chrysops nigripes Zetterstedt and Chrysops probably zinzalus Philip (Diptera: Tabanidae) in a subarctic Labrador peatland

A total of 476 tabanid larvae, including 108 Chrysops nigripes and 145 Chrysops probably zinzalus, were obtained from regular collections made from early June through late August 1990–1991 in Iron Arm Fen, a minerotrophic peatland located in subarctic Labrador near Schefferville, Quebec. Changes in head capsule and total body length-frequency distributions among successive sampling periods and years suggest very slow growth rates for Chrysops species at subarctic latitudes; life cycles may require 7–8 years to complete.
