“…As reported for various haematophagous flies (e.g. Anderson & Hoy, 1972;LePrince et al, 1992;Mullens, 1995) our C0,baited traps selectively attracted and caught only inseminated host-seeking C.tmmpe and H.tarandi females. Because the gonotrophic status and reserve FB of such females was the same as that of inseminated females caught on and around reindeer, we believe the traps functioned as effective host mimics.…”

Dissection of flies caught in northern Norway revealed that only mated, gravid females of H.tarandi (L.) and larviparous C.trompe (Modeer) were caught in host-mimicking CO2-baited traps. Trapped females had the same gonotrophic and fat body (FB) conditions as females caught on and around reindeer. Most trapped females of both species were of middle to old age, having only one-half to no FB reserves left and only a few to moderate numbers of eggs or larvae remaining. Most young females trapped also had previously oviposited or larviposited at least once, and some newly eclosed, mated females were present throughout the fly season. Based on the known location of reindeer herds, it was evident that trapped flies that had recently oviposited or larviposited had dispersed into the trapping area from 25-100 km away. Declining FB reserves sustained wild-caught C.trompe females (and in utero larvae) in the laboratory for 14 days and H.tarandi females for 18 days. Reserve FB also was depleted during long flights. Females of both species that flew for the longest times (5.1-11.7 h) on a laboratory flight mill had low FB reserves, but nearly maximum numbers of eggs or larvae. Conversely, most females that flew for less than 5 h on the light mill had little or no FB remaining, and few eggs or larvae. The large FB reserves accumulated as larvae feed in the vertebrate host enable the non-feeding adults to survive and infect their hosts even after prolonged periods of flight-inhibiting climatic conditions.

“…The climate is subarctic and of a continental type (BRUUN, 1967), and mean temperatures for May, June, July, August and September were 1.6, 8.1, 12.3, 9.9 and 4.7"C, respectively. The traps used were similar to those used to capture many taxa of North American haematophagous Diptera (ANDER-SON etal., 1974;ANDERSON and HOY, 1972), Cephenemyia species (ANDERSON and OLKOWSKI, 1968), calliphorids and the reindeer oestrids Hypoderma (= Oedemagena) tarandi (L.) and C. trompe (ANDERSON and NILSSEN, 1996). These traps capture flying insects equally well from all directions.…”

Effect of 1‐octen‐3‐ol in field trappingAedesspp. (Dipt., Culicidae) andHybomitraspp. (Dipt., Tabanidae) in subarctic Norway

A field test with 1-octen-3-01 (octenol) used as an attractant in flight traps was carried out in subarctic Norway (69"40'N, 23"30'E) during four warm days in July 1993. Aedes spp. (Dipt., Culicidae) were caught in significantly (P = 0.000 1) higher numbers in octenol-baited traps than in empty control traps (approximately seven-fold increase), as was Hybomitra lundbecki Lyneborg (Dipt., Tabanidae), (P = 0.0003) (approximately nine-fold increase). Octenol also increased but not significantly (P = 0.09, n = 14) the catch of Chrysops relictus Meigen (Dipt., Tabanidae). The study confirmed the established role of octenol as an attractant of biting Diptera. The advantage of using octenol instead of, or in combination with, carbon dioxide in control or surveillance of such insects is discussed.

“…Because these flies can be difficult to catch around their hosts, and because of the migratory behaviour of the host, hostmimicking fly traps would be valuable aids. Because previous studies (Anderson & Olkowski, 1968;Anderson & Hoy, 1972;Anderson, unpubl. data) be caught in C0,-baited insect flight traps, we evaluated the performance of such traps for catching oestrid flies that parasitize reindeer in subarctic Norway.…”

At 340-360 km North of the Arctic Circle in Norway, Hypoderma tarandi (L.) and Cephenemyia trompe (Modeer) females were caught in baited traps from 10 July to 21 August. During three summers, adverse climatic conditions inhibited flight activity of these oestrids on 56-68% of the days. Flies were not caught prior to or after these dates, nor at winds above 8 m/s, temperatures below 10 degrees C, light intensities below 20,000 lux, or during periods of rain or snow. CO2-baited insect flight traps caught significantly more H.tarandi females than non-baited traps. However, neither a white reindeer hide or reindeer interdigital pheromone glands enhanced the attraction of CO2 to H.tarandi or C.trompe. Hypoderma tarandi females also were attracted to mobile people, but not to stationary individuals. There were no significant differences in the number of C.trompe or H.tarandi caught in CO2-baited traps in a birch/willow woods, on the treeless vidda (= tundra-like biome), or at woods:vida ecotone sites. Flies were caught in traps on days when the nearest reindeer herds were 25-100 km away. Significantly more H.tarandi and C.trompe were caught from 09.30 to 14.30 hours than from 14.30 to 19.30 hours; no flies were caught from 20.00 to 07.00 hours (Norwegian Standard Time = NST). Because of CO2-baited traps caught from hundreds to thousands of mosquitoes, blackflies and Culicoides midges, when climatic conditions inhibited oestrid activity, reindeer aggregations and movements attributed to insect attacks during warm sunny days may be largely in response to attacks by H.tarandi and C.trompe.
