The stable fly, Stomoxys calcitrans (L.) is a blood-sucking muscid fly species, with a worldwide distribution and high veterinary-medical importance. In this study, four mite species were collected from stable flies in Hungary. One mite species (Trichotrombidium muscarum (Riley, 1878)) from the family Microtrombidiidae was parasitic on the flies, collected in high numbers from their bodies. The other three species were found in small numbers on the flies, which they use only for transportation. The latter included the phoretic female of Pediculaster mesembrinae (Canestrini, 1881) (Acari: Siteroptidae), the phoretic deutonymph of the Halolaelaps sexclavatus (Oudemans, 1902) (Acari: Halolaelapidae) and Macrocheles subbadius (Berlese, 1904) (Acari: Macrochelidae). This is the first record of an association between the stable fly and two mite species (Trichotrombidium muscarum and Halolaelaps sexclavatus). A new, completed list and identification key of known stable fly associated mites are also provided.

Stable fly (Stomoxys calcitrans) is one of the most important blood-sucking insects that has a potential economic impact on the livestock industry. The species has cosmopolitan distribution and is abundant in livestock barns, stables, and pastures. This study identified the presence of S. calcitrans in dairy barns, on fences and foliages around dairy cattle farms in District 12, Cu Chi, Hoc Mon and Binh Chanh Distrist of Ho Chi Minh city, and recorded its blood-sucking behavior. Both sexes of stable flies have blood-sucking behavior and cause much pain and annoyance to catlle resulting in interrupted grazing. Morphological characteristics of S. calcitrans were reported and compared with those of the housefly (Musca domestica). Statistical data collected from two cattle farms in District 12 showed that the boold-sucking flies occured throughout the year in farms with 3.40 flies per leg of cattle in June and 2.35 flies per leg of cattle in September. The number of flies per leg of cattle crossed economic threshold (< 2 stable flies per leg of catlle). However, with 40–180 cows raised per farm, the farmers have not been aware of the presence and impact of the boold-sucking flies. The stable flies S. calcitrans would cause huge losses in productivity and quality of meat and milk when the cattle husbandry is developed on industrial scale. Therefore, identification and control of density of the blood- sucking fly should be seriously considered.

Enterobacter sakazakii is an opportunistic foodborne pathogen that causes meningitis, enterocolitis, and sepsis, primarily in immunocompromised infants. Previously, it was suggested that stable flies, Stomoxys calcitrans, were a vector or reservoir of this pathogen. In our study, by means of a culturing approach combined with 16S rDNA PCR–restriction fragment length polymorphism genotyping and sequencing, we screened 928 individual stable flies collected in Kansas and Florida. Two stable flies (0.2%) were positive for E. sakazakii. In addition, 411 (44%) stable flies carried bacteria-forming red colonies (presumably enterics) on a violet red bile glucose agar (mean count = 6.4 × 104 CFU per fly), and 120 (13%) stable flies carried fecal coliforms (mean count = 8.7 × 103 CFU per fly). Sequencing of 16S rDNA showed that enterics from violet red bile glucose agar were represented by several genera, including Escherichia, Shigella, Providencia, Enterobacter, Pantoea, Proteus, Serratia, and Morganella. Our study shows that stable flies carry bacteria typically present in animal manure (a developmental site of stable fly larvae), which indicates that the natural reservoir of E. sakazakii is the digestive tract or manure of domestic animals. The low prevalence of E. sakazakii associated with stable flies suggests that stable flies do not play a major role as a reservoir or vector of this pathogen.

AbstractIn outdoor cage studies undertaken in the late summer of 1973, a method of estimating the absolute density of a stable fly (Stomoxys calcitrans (L.)) population was developed by correlating the average number of insects feeding or resting on a calf to the total number in the cage. Under the same cage conditions, where emigration, immigration, and to some extent, predation have been excluded, the daily mortality rate of normal stable flies marked with a fluorescent dye ranged from 25.3% to 27.3% dependent upon the sampling technique. Marker dyes have a deleterious effect on survival but surprisingly gamma irradiated flies succumbed at a lower rate than normal individuals.

Abstract The stable fly, Stomoxys calcitrans (L.), is a bloodsucking ectoparasite that causes irritation and distress to livestock, wildlife, and humans. Both sexes are vicious blood-feeders that feed on a variety of animals. Optically attractive sticky traps have been used to capture stable flies, and some companies claim that sticky traps can protect animals from the bites of stable flies. To further investigate the protective ability of sticky traps, Home and Garden Mosquito (HGM) traps were selected for evaluations at the University of Florida Horse Teaching Unit (HTU). Broodmares coated with fluorescent dust were either tethered to a post in the center of a paddock or released untethered into a paddock. HGM sticky traps were placed at the four compass points and four selected distances from the paddock center to capture stable flies before (unmarked) or after (marked) they visited the horses. More than 40% of flies captured on traps placed closest to the horses were marked. This indicates that the traps did not prevent the flies from visiting the horses. A percentage of marked and unmarked stable flies showed signs of blood in their guts indicating recent feeding. For unknown reasons, the number of stable flies marked with Signal Green dust exceeded the numbers marked with other colors. Although the HGM traps caught ample numbers of stable flies, the traps did not prevent stable flies from feeding on the horses. More work is needed to determine optimal trap placement and densities required to maximize stable fly management with traps.

Clinical Cases

Data on the implication of the stable fly (Stomoxys calcitrans, Diptera: Mus­cidae), in the transmission of Anaplasma marginale in tick-free cattle is scarce. Hence, the objective of this investigation was to detect the presence of DNA from A. marginale in stable flies caught near a bovine herd, which has been maintained free of ticks for 40 years, and occasionally presents some clinical cases of anaplasmosis. Twenty-four batches of S. calcitrans (15 flies each) were collected in the morning and in the afternoon twice a week (except for one catch in one week of September and one catch in one week of December) during 12 catching days in a period of four months. Their DNA was obtained and analysed by nested PCR (nPCR) to identify the presence of A. marginale DNA. Seven of the batches (29.16 %) were pos­itive for A. marginale, as detected by an nPCR that targets the A. marginale msp5 gene. Similarly, in two out of 12 catching days (16.66 %), those S. calcitrans batches collected in the morning and in the afternoon, were pos­itive for A. marginale, while those S. calcitrans groups collected in three out of 12 catching days (25 %), were positive for the rickettsia. The obtained re­sults suggest that A. marginale transmission is carried out mechanically by S. calcitrans, favouring the circulation and maintenance of the microorganism in this particular bovine herd.

AbstractIn 1995, Nasonia vitripennis (Walker) (Hymenoptera: Pteromalidae), a commercially available pupal parasitoid of the house fly, Musca domestica L., and stable fly, Stomoxys calcitrans (L.) (Diptera: Muscidae), was purchased to examine the status of wasps being sold to Manitoba producers. Percentage of pupae parasitized, numbers of parasitoids per pupa, total parasitoids, and parasitoid sex ratio were determined for each shipment of parasitoids received. To determine the extent to which these wasps could successfully parasitize house flies and stable flies, parasitoids were released weekly in four Manitoba dairy barns and levels of parasitism estimated. In 10 622 freeze-killed sentinel house fly pupae, 2.2% were parasitized throughout the season by N. vitripennis, and 5.8% were parasitized by eight other species of parasitoids. Of 11 897 naturally occurring house fly and stable fly pupae, 0.6% were parasitized by N. vitripennis, and 3.4% by eight other species of parasitoids. In four barns where there were no releases of N. vitripennis, 1.1% of 11 779 sentinel pupae were parasitized by four species of parasitoids and 3.8% of 8384 naturally occurring house fly and stable fly pupae were parasitized by nine species. The release of an estimated 3 648 093 N. vitripennis did not result in substantial parasitism in either sentinel pupae or naturally occurring pupae. In 1996, live sentinel house fly pupae (n = 50 842) and house fly and stable fly pupae occurring naturally (n = 4691) were collected in two of the nonrelease barns from the 1995 study to examine the activity of endemic parasitoids. Of the sentinel and naturally occurring pupae sampled, 4.0% and 9.4% were parasitized, respectively. Phygadeuon fumator Gravenhörst (Hymenoptera: Ichneumonidae) was the most abundant parasitoid, accounting for 97.4% and 79.9% of parasitoids collected from sentinel pupae and naturally occurring pupae, respectively. Other parasitoids included Urolepis rufipes (Ashmead), Muscidifurax raptor Girault and Sanders, Muscidifurax zaraptor Kogan and Legner, Spalangia subpunctata Först, Spalangia cameroni Perkins, Spalangia nigra Latreille, and a species of Trichomalopsis Crawford (Hymenoptera: Pteromalidae).

Abstract Population explosions of the stable fly (Stomoxys calcitrans) have become a serious concern for livestock producers near sugarcane mills in some regions of Brazil due to the insect’s massive reproduction on sugarcane byproducts and waste. Despite the limited efficiency of insecticides for controlling stable fly outbreaks, producers still rely on chemical control to mitigate the alarming infestations in affected areas. This study evaluated the susceptibility of S. calcitrans populations to cypermethrin in the state of Mato Grosso do Sul, Brazil. Stable flies were tested from three field populations and two colonies, established from flies previously collected at sugarcane mills. Wild flies were collected with Nzi traps in areas of sugarcane plantations. Both wild and colonized flies were exposed to eleven concentrations of cypermethrin in impregnated filter paper bioassays. All the populations proved to be resistant to cypermethrin, with resistance factors among field populations ranging from 6.8 to 38.6. The intensive use of insecticides has led to the development of pyrethroid resistance in stable fly populations in the proximities of sugarcane mills in the state of Mato Grosso do Sul.

Abstract Six species of birds of the family Sternidae are often found on the southern coast of South America. Sterna trudeaui, S. hirundinacea, Thalasseus maximus, T. acuflavidus and Sternula superciliaris are South American residents and Sterna hirundo, a Nearctic migrant. At least 500 species of nasal mites have been described around the world, and Rhinonyssidae is the most diverse family. These mites are bloodsucking endoparasites that inhabit the respiratory system of birds. This study aimed to report on occurrences of nasal mites in Sternidae on the southern coast of Brazil. Of the 106 birds analyzed, 8.5% (9 birds) were parasitized by nasal mites. This report provides the first record in the Neotropical region for two mite species, Sternostoma boydi and Larinyssus orbicularis parasitizing Thalasseus acuflavidus and Sternula superciliaris. No nasal mites were found in Sterna trudeaui or Thalasseus maximus. One host individual (T. acuflavidus) was parasitized by two species of nasal mites, S. boydi and L. orbicularis.

AbstractPterin accumulation in response to temperature and time was studied in male and female stable flies Stomoxys calcitrans (L.). Pterins accumulated as a function of temperature integrated over time. The threshold for pterin accumulation was estimated at 6.5 °C. The relationship between pterin content (RF/mm head capsule width) and accumulated degree-days above 6.5 °C (DD6.5) was determined to be RF/mm = 38,06 + 1.258*DD6.5 for females and RF/mm = 37.65 + 1.765*DD6.5 for males. Ovarian development, measured by follicle length and degree of vitellogenesis, was also related to DD6.5 and pterin concentration. The relationship between y1 = follicle length (mm) and x = DD6.5/200 was y1 = 0.11 + 0.78* [1−exp(− 18.34*x)]**99.86 and between vitellogenic stage (y2) and x was y2 = 0.04 + 3.96*[1−exp(− 11.48*x)]**6.67. Stable flies had a temperature threshold of 8 °C for oviposition.
