Synanthropy of Muscidae (Diptera) in the city of Valdivia, Chile

The objective of the present study was to determine the index of synanthropy of adults of Muscidae species collected in Valdivia, Chile (39°48'S; 73°15'W). The flies were collected monthly between September 1996 and August 1997 at three different locations, representing urban, rural and natural environments. Rat carcasses, chicken viscera, and fish viscera were used as bait. Six species of Muscidae were collected: Psilochaeta chalybea (Wiedemann) was dominant in urban and rural habitats, being eusynanthropic. The second species in importance was Hydrotaea acuta (Stein), being hemisynanthropic and more abundant in the natural environment. Ophyra ignava (Harris) was another species captured in relatively large numbers, and showing eusynanthropic characteristic. The remaining three species, Musca domestica L., Palpibracus valdiviensis (Couri & Pamplona), and Mu scina stabulans (Fallén) were captured in low numbers. In addition to the indexes of synanthropy, monthly abundances were determined and discussed, as well as the efficiency of the different baits used to collect the flies. The medical and sanitary importance of the flies was also assessed.

The structure of a high latitude plant‐flower visitor system: the dominance of flies

The species richness of insect flower visitors to all angiosperms at a subarctic‐alpine site in northern Sweden was described and the plant‐flower visitor matrix was analysed and compared to other high latitude systems and with systems from lower latitudes. In the habitat, 23 plant species had a total of 242 interactions with 388 flower‐visiting insects, belonging to 118 taxa. Connectance of the plant‐flower visitor matrix was 8.9. Comparing our findings with other studies, we get that the proportion of dipteran species of the total pollinator fauna increases with latitude but that the proportions of species of Diptera, Hymenoptera and Lepidoptera do not vary significantly among high latitude systems. Muscidae and Empididae were more abundant and generalised than other dipteran families visiting flowers in the arctic, their proportions of the total Diptera fauna increase with latitude and they are the most widespread families of flower‐visiting insects in the arctic. Several Muscidae species are typical to alpine habitats in the arctic‐subarctic zone. These species have special pollen feeding behaviour and an elongated proboscis, which improves access to closed flowers.Compared to other published pollination system studies, the connectance of low latitude systems ranges between 3.4 and 28.1, whereas high latitude and high altitude systems vary between 8.6 and 19 (‐60).

Native Hawaiian Insects Attracted to the Semiochemical Methyl Eugenol, Used for Male Annihilation of the Oriental Fruit Fly (Diptera: Tephritidae)

This study addressed the potential susceptibility of native Hawaiian insects to the semiochemical methyl eugenol used for male annihilation of the oriental fruit fly, Bactrocera dorsalis (Hendel). The effects of trap type (methyl eugenol, methyl eugenol + toxin, toxin only, and control) and trap height (0, 1, 2, or 4 m above ground) were studied in native forest on the island of Kauai. A malaise trap was used to determine the relative abundance of insects in the immediate vicinity of the methyl eugenol traps. Seven species of native Hawaiian Drosophilidae, two species of Muscidae, and one species of Phoridae were found to be attracted to methyl eugenol. For four other taxa, including species of Miridae, Anobiidae, and Proctotrupidae, attraction to methyl eugenol is suggested but equivocal. For all species except Drosophila villosipedis (Drosophilidae) and Brachyserphus hawaiiensis (Proctotrupidae) both males and females were attracted to methyl eugenol. For Drosophila perissopoda , Drosophila basimacula , Scaptomyza varipicta , and Scaptomyza rostrata , ground level traps caught significantly more individuals than traps above ground, and for all drosophilids, 4-m high traps caught the fewest individuals. Among non-Drosophilidae, trap height was not a significant factor in captures for only the Anobiidae and Sarona species (Miridae). Megaselia sp. (Phoridae) was similar to Scaptomyza tantalia (Drosophilidae) in that almost all individuals were captured in ground level traps. Orthotylus sp. (Miridae) was the only species in which 4-m high traps caught the greatest number of individuals. For Lispocephala species (Muscidae) and B. hawaiiensis , 1–2-m high traps tended to catch more individuals than the ground-level or 4-m high traps. Malaise trap data suggest that methyl eugenol traps either attracted these species roughly in proportion to their local abundance ( D. villosipedis , D. basimacula ) or they captured only a portion of the local pool of individuals ( S. varipicta , D. perissopoda , D. kokeensis , Lispocephala spp. ). Because of the low level of attraction displayed by the native insects and the potential to mitigate the impact by placement of baits in the forest canopy, it is suggested that an environmentally acceptable application of methyl eugenol can be devised for use in the Hawaiian Islands.

Seasonal Abundance and Spatial Distribution Patterns of Three Adult Muscoid (Diptera: Muscidae) Species on Equine Premises

Adult face fly, Musca autumnalis De Geer, stable fly, Stomoxys calcitrans (L.), and horn fly, Haematobia irritans (L.), populations on four Kentucky horse farms were monitored weekly from late April to mid-October 1987 and 1988 using dry ice-baited canopy traps and visual counts of flies on pastured horses. Face flies were most abundant during May 1987 and June of both years followed by peak stable fly activity during mid-June, July, and August of both years and peak horn fly activity during mid-September of both years. Canopy trap collections of face flies were correlated with visual counts of face flies on pastured horses for 1987 and 1988. Horn flies were not collected in the canopy traps, and stable flies were not observed on pastured horses. Using visual count data to determine the degree of population aggregation, horn fly populations were found to be more contagious than face flies as populations increased on pastured horses. From the canopy trap data, face fly and stable fly populations had similar aggregation indices or similar distribution patterns as populations increased.

Carriage of Corynebacterium pyogenes by the cattle nuisance flies Hydrotaea irritans (Fallén) and Musca autumnalis (De Geer)

Two species of cattle-visiting Muscidae were experimentally contaminated with C. pygenes, a pathogen involved in the aetiology of summer mastitis. Surface contamination persisted for at least 4 days. Since M. autumnalis would not feed on media containg C. pyogenes the bacterium did not persist internally. All C. pyogenes were eliminated from the gut of H. irritans in 4 days. H. irritans is thus more likely to transmit C. pyogenes than is M. autumnalis but only by mechanical transfer, and is not a true vector.

The distribution of five species of flies (Diptera: Muscidae) over the bodies of dairy heifers in England

AbstractFive species of Muscidae were found to be commonly associated with dairy heifers in three areas in southern England. The biting flies Haematobosca stimulans (Mg.) and Stomoxys calcitrans (L.) were relatively rare and fed from the back, flanks and legs. The horn fly, Haematobia irritans (L.), was present in highest numbers; it rested on the back and fed on the legs, belly and occasionally on the teats. Musca autumnalis Deg. was found mainly on the head and had a restricted season. Hydrotaea irritans (Fall.) had a marked diurnal variation in activity, being most abundant in the morning and evening. It was found on the head but predominantly on the belly and teats. When judged by its site preference on cattle, it is the fly most likely to be involved in the transmission of summer mastitis.

Seasonal abundance during the summer months of some cattle‐visiting Muscidae (Diptera) in northeast England

Abstract. 1. Regular samples of flies swarming around cattle in Northumberland, England, were collected from late May to early October 1980–82, during weather judged to be suitable for fly activity.2. Results were grouped into weekly periods and averaged to reduce variation caused by the weather.3. For all species of Muscidae that were caught in reasonable numbers, the changes in abundance through the season are described.4. The proportion of each species in the total sample is discussed; biting species were not sampled as efficiently as were non‐biting species. Hydrotaea trritans and Morellia simplex were the most numerous species forming 49% and 32% of the catch respectively.5. The total numbers of flies were low at the beginning of the sampling period, rose to a maximum in mid‐July, stayed high until mid‐September and then declined by October.

AbstractNotes are given on the life of Charles De Geer ( 1720-1778), on the history of his insect collection, and on some nomenclatural aspects of his work. The 10 species he described into the present families Fanniidae, Anthomyiidae and Muscidae are listed, their typematerial and identities discussed, and iectotypes designated where appropriate. 4 new synonyms are established: Fannia scalaris (Fabricius, 1794) (syn: minordomestica De Geer, 1776), Pegomya steini Hendel, 1925 (syn: fungorum De Geer, 1776, preocc.), Pegomya testacea (De Geer, 1776) (syn: silacea Meigen, 1830), and Lucilia caesar (Linnaeus, 1758) (syn: viridicaerulea De Geer, 1776).

Muscidae (Diptera): experimental vectors of hog cholera virus.

Since outbreaks of hog cholera often occur during late summer or early fall when muscid flies are numerous, 3 species of Muscidae, Stomoxys calcitrans (L.), Musca domestica L., and M. autumnalis De Geer, were tested as vectors. All 3 species experimentally transmitted hog cholera virus (HCV) from infected pigs to susceptible pigs in the disease isolation chambers of the Veterinary Services Diagnostic Laboratories, Ames, Iowa. Successful mechanical transmission was accomplished by S. calcitrans and M. domestica after 24-hr delays and by M. autumnalis after a 48-hr delay. The laboratory diagnostic test used to detect HCV was the fluorescent-antibody cell culture technique (FACCT).
