physiological age determination in female stomoxys calcitrans linnaeus (diptera: muscidae).the primary sex organs of female stomoxys calcitrans consist of a single pair of ovaries, each containing 80-100 polytrophic ovarioles. a natural population of these females can be grouped according to age into different reproductive categories. the technique described below defines these categories and enables one to distinguish between newly-emerged, nulliparous and uniparous females and females that have reproduced twice (biparous) or more (pauciparous).19807413165
a field trial to determine the effect of fly control using permethrin on milk yields in dairy cattle in the uk.permethrin, applied by knapsack sprayer or spray arch, was used to control flies on cattle in two dairy herds in the united kingdom. the spray washes were applied at nominal rates of 0.5 litre of 0.1 per cent permethrin per animal and 1.0 litre of 0.05 per cent permethrin per animal respectively. the individual milk yields of two groups of cows were recorded before and after treatment. in both cases there was a significant increase in milk yield after treatment. the mean yield per cow per day du ...19807445328
field trials to assess the efficacy of permethrin for the control of flies on cattle.permethrin [3-phenoxybenzyl (+/-) cis, trans--2,2dimethyl-3-(2,2-dichlorovinyl) cyclopropane-1-carboxylate], a new synthetic pyrethroid, was applied to cattle on farms in the united kingdom to assess its efficacy in fly control under field conditions. when 250 ml 0.1 per cent permethrin was applied to the backs of cattle using a knapsack sprayer, adequate control of horn flies, haematobia irritans, was achieved for over three weeks. application of 500 ml 0.1 per cent all over each animal gave on ...19807445329
the temperature preferences of the motile stages of stomoxys calcitrans linnaeus (diptera: muscidae).when adult stomoxys calcitrans were exposed to a temperature gradient, 66% of them selected temperatures between 20, 1 and 32, 5 degrees c. the larval stages preferred temperatures between 19, 5 and 33, 2 degrees c. although the differences in the temperature preferences of the different larval stages were not significant, the fully-fed larvae appear to prefer slightly cooler conditions than the feeding stages. the temperature preferences of both the adults and the larvae are not influenced by t ...19807454236
exposure to stable flies reduces spatial learning in mice: involvement of endogenous opioid systems.biting flies influence both the physiology and behaviour of domestic and wild animals. this study demonstrates that relatively brief (60 min) exposure to stable flies, stomoxys calcitrans (l.), affects the spatial abilities of male mice. stable fly exposure resulted in poorer subsequent performance in a water maze task in which individual mice had to learn the spatial location of a submerged hidden platform using extramaze visual cues. determinations of spatial acquisition and retention were mad ...19957548949
structural characterization of muscles and epithelial sheaths of the oviduct of stomoxys calcitrans (diptera: muscidae).fine structure of both muscle and epithelial cells in the oviduct of stomoxys calcitrans (l.) was characterized. each tubular section of the oviduct consisted of an inner epithelial sheath enveloped by an outer network of muscle fibers that showed noticeable variation in cross-sectional thickness. some regions consisted of a single cellular layer, whereas others were composed of two or more layers of cells. moreover, a wide variation in muscle fiber orientation was observed, with some cells appe ...19957616524
temperature and population density effects on feeding activity of stomoxys calcitrans (diptera: muscidae) on cattle.the relationship of population density and temperature to feeding activity of stable flies, stomoxys calcitrans (l.), on cattle was studied by placing cattle in constant temperature chambers with controlled fly density and temperature. the number of flies per front leg declined within hours after release but increased with fly density and temperature. the time flies spent on the host during a 5.5-h exposure period ranged from < 2.5 min at temperature < 16 degrees c to > 34 min when temperature w ...19957650712
biology and control of tabanids, stable flies and horn flies.tabanids are among the most free-living adult flies which play a role as livestock pests. a single blood meal is used as a source of energy for egg production (100-1,000 eggs per meal), and females of certain species can oviposit before a blood meal is obtained (autogeny). therefore, the maintenance of annual populations requires successful oviposition by only 2% of females. wild animal blood sources are usually available to maintain annual tabanid populations. larval habitats are also independe ...19947711307
[the absolute count of the housefly (musca domestica) and the stable fly (stomoxys calcitrans) in buildings for cattle].the direct correlative dependence between indices of absolute and relative number of two fly species calculated by peterson's method is shown. the way of calculation of the absolute number of m. domestica and s. calcitrans and the receipt of the selection from subpopulations, which take in account peculiarities of adult fly distribution in different technological regimes of cattle keeping, peculiarities of daily activity and influence of temperature-photo factors on imago, are proposed. the atte ...19947816502

overwintering of the stable fly (diptera: muscidae) in southeastern nebraska.adult stable flies, stomoxys calcitrans (l.), were monitored during three winters at two, four, and 13 locations with alsynite fiberglass traps and by examination of the interiors of buildings. no stable flies were found inside buildings during the winter. adult stable flies were consistently caught on alsynite traps at one location during two winters and at two other locations during one winter. distribution and physiological age of these flies indicate that they emerged from pupae that had dev ...19947836614
isolation and characterization of a diuretic peptide common to the house fly and stable fly.an identical crf-related diuretic peptide (musca-dp) was isolated and characterized from whole-body extracts of the house fly, musca domestica, and stable fly, stomoxys calcitrans. the peptide stimulates cyclic amp production in manduca sexta malpighian tubules and increases the rate of fluid secretion by isolated musca domestica tubules. the 44-residue peptide, with a mol.wt. of 5180, is amidated, and has the primary structure: nkpslsivnpldvlrqrllleiarrqmkentrqvelnrailknv-nh2. musca-dp has a hi ...19947991460
vector control by removal trapping.the classic approach to vector control where large tracts of land are treated with an insecticide has many shortcomings. these include high cost, chemical resistance of target species to many of the widely used insecticides, a lack of public acceptance, and the detrimental effect of sprays on nontarget species. removal trapping, the use of visual, auditory, and olfactory attractants to lure target species into small areas where they are killed, has recently received well-deserved attention as a ...19948024078
inundative releases of pteromalid parasitoids (hymenoptera: pteromalidae) for the control of stable flies, stomoxys calcitrans (l.) (diptera: muscidae) at confined cattle installations in west central nebraska.fly pupal parasitoids, primarily muscidifurax raptor girault and sanders and spalangia nigroaenea curtis, purchased from commercial insectaries, failed to reduce numbers of stable fly, stomoxys calcitrans (l.), significantly despite weekly releases of high numbers at one feedlot and one dairy during 1990 and a different feedlot and dairy in 1991. parasitoid emergence from stable fly puparia were not significantly greater in the confinements where releases were made compared with confinements whe ...19948027475
retention and attempted mechanical transmission of ehrlichia risticii by stomoxys calcitrans.the ability of adult stomoxys calcitrans (l.) (diptera: muscidae) to retain viable ehrlichia risticii (rickettsiaceae), the aetiologic agent of potomac horse fever (phf), and mechanically transmit the pathogen from citrated bovine blood artificially infected with e. risticii to susceptible mice was studied. viable e. risticii were found in the digestive tract of s. calcitrans 3 h after the flies had engorged to repletion on infected blood; however, no e. risticii were detected in flies > or = 2 ...19948161843
solar-powered electrocuting trap for controlling house flies and stable flies (diptera: muscidae).a portable trap was constructed that was visually attractive to house flies, musca domestica l., and stable flies, stomoxys calcitrans (l.), outdoors. the trap was made of a white and yellow pyramid placed on top of a white vertical base that had large cutouts in each side. attracted flies were killed by means of solar-powered electrocuting grids. three traps killed an average of 1,360 house flies and 1,190 stable flies per day at a manure dump and were effective in attracting flies under both c ...19938254633
seasonal abundance of stable flies and house flies (diptera: muscidae) in dairies in alberta, canada.seasonal abundance of stable flies and house flies was studied at four dairies in southern alberta, canada, from may to october in 1989, 1990, and 1991. stable flies were active from may to october in all years and showed population peaks in august and september. the weekly rate of change of stable fly populations was influenced by temperature and accumulated degree-days above 10 degrees c. the weekly rate of change of stable fly populations showed four peaks which were attributed to the emergen ...19938254636
allozyme variation in stable flies (diptera: muscidae).polyacrylamide gel electrophoresis was used to resolve allozymes in the cosmopolitan blood-feeding stable fly, stomoxys calcitrans (l.). nineteen of 38 loci were polymorphic (53%). mean heterozygosities among all loci and among only polymorphic loci were 0.096 and 0.182, respectively. these gene diversity measures are about half those among other muscid diptera. variation in gene frequencies was examined in 10 natural stable fly populations from iowa and minnesota. gene frequencies were homogene ...19938259926
description and biology of trichopria painteri n.sp. (hymenoptera: diapriidae), a solitary parasitoid of stomoxys calcitrans (diptera: muscidae) from harare, zimbabwe.taxonomic description and life history are given of trichopria painteri n.sp. (hymenoptera: diapriidae), a solitary endoparasitoid that emerged from stomoxys calcitrans (l.) (diptera: muscidae) pupae collected at an agricultural installation near harare, zimbabwe, africa. although its low level of parasitism. high immature mortality and short adult life span would require augmentative releases of t.painteri, this parasitoid could reduce isolated field populations of s.calcitrans to an acceptable ...19938268491
on the transmissibility of eperythrozoon suis by stomoxys calcitrans and aedes aegypti.the stable fly, stomoxys calcitrans (linnaeus), and the yellow fever mosquito, aedes aegypti (linnaeus), were utilized to determine their capability to transmit eperythrozoon suis splitter between swine. three groups of each insect in each trial were allowed to feed on a pig previously infected with e. suis and then transferred to susceptible splenectomized pigs. as a control, one group of each insect was fed on a non-infected pig and then transferred to a susceptible pig. stable flies were tran ...19938291187

average daily gains of brahman-crossbred and english x exotic feeder heifers exposed to low, medium, and high levels of stable flies (diptera: muscidae).brahman-crossbred and english x exotic feeder heifers were exposed to low (5 per leg), medium (12 per leg), and high (30 per leg) stable fly, stomoxys calcitrans (l.), population levels to test relative tolerance of these cattle breeds to stable flies. the brahman-crossbred heifers were tolerant to stable flies only when they were 12-13 mo old. at the same age, the english x exotic heifers sustained reductions in average daily gain (adg) at all three stable fly population levels of 0.22 kg/d (11 ...19938376651
effects of two blood-feeding regimes on mortality and female reproduction in a laboratory colony of stable flies, stomoxys calcitrans.stable flies (stomoxys calcitrans l.) deprived of a bloodmeal until 3 days post-emergence had higher mortality rates than control flies fed from the day of emergence. fat bodies of deprived females required one more bloodmeal to reach maximum size, and maximum size was smaller, than fat bodies of control females. ovarian development did not commence prior to feeding in deprived flies, and proceeded more slowly thereafter, resulting in a one blood-meal delay in egg maturation in deprived flies. d ...19938481526
population dynamics of some synanthropic fly species in different habitats in buraydah, saudi arabia.the population dynamics of five synanthropic fly species, chrysomyia rufifacies, musca d. domestica muscina stabulans f. sarcophaga haemorrhoidalis, and stomoxys calcitrans, were studied at three different habitats in buraydah, saudi arabia. the chosen habitats were the slaughter house, the cattle market and the rubbish dumps. the number of flies caught per twenty sticky bands was taken monthly, for a whole year, as an index to the fly population at that habitat during that month. m. d. domestic ...19938482859
spread of lumpy skin disease in israeli dairy herds.fourteen of the 17 dairy herds in peduyim, an israeli village, became infected with lumpy skin disease during a period of 37 days in august and september 1989. one cow in one neighbouring village and four cows in another neighbouring village also became infected, probably through being treated by a veterinarian who treated cows in peduyim. circumstantial evidence suggests that the original infection was brought to peduyim and spread by stable flies (stomoxys calcitrans) carried by the wind from ...19958533249
urine delivery of cyromazine for suppressing house and stable flies (diptera: muscidae) in outdoor dairy calf hutches.in a series of 4 trials, dairy calves housed in outdoor hutches were administered technical cyromazine daily at rates of 0, 0.1, 0.5, and 1.0 mg/kg body weight. cyromazine was excreted primarily in the urine. the 2 highest rates prevented the development of immature stages of both the house fly, musca domestica l., and the stable fly, stomoxys calcitrans (l.). analysis of calf body tissues for cyromazine and its metabolite, melamine, indicated that highest combined residues ( < or = 0.35 ppm) we ...19968642111
population genetics and gene variation of stable fly populations (diptera:muscidae) in nebraska.genetic variation in stable fly, stomoxys calcitrans (l.), populations from nebraska, canada, and texas was sampled. four of 12 allozyme loci were polymorphic, with an average of 1.7 alleles per locus. observed and expected heterozygosities were 0.086 and 0.070, respectively. nei's genetic distance between populations averaged 0.001 and ranged from 0.000 to 0.005. wright's f statistics revealed greater variation within than among populations. allele frequencies were homogeneous among temporal sa ...19968667389
localization of myosuppressinlike peptides in the hypocerebral ganglion of two blood-feeding flies: horn fly and stable fly (diptera:muscidae).the insect peptides leucomyosuppressin (pedvdhvflrfamide) and dromyosuppressin (tdvdhvflrfamide) have identical chemical sequences with the exception of the n-terminal amino acid; both inhibit spontaneous contraction of insect visceral muscles. neurons in the hypocerebral ganglion of horn fly, hematobia irritans (l.), and stable fly, stomoxys calcitrans (l.), were found to contain material immunoreactive to antiserum produced against the c-terminal of leucomyosuppressin, but not to the n-termina ...19968667397
structural characterization of peripheral nerve cells and nerve-muscle junctions of the oviduct of stable fly (diptera:muscidae).fine structure of both peripheral nerve cells and neuromuscular junctions associated with the oviduct of stable fly. stomoxys calcitrans (l.), was described. twelve or more multipolar peripheral neurons were found along major branch nerves that enter the ovipositor. several were suspended in the haemacoel and others were in close proximity to the surface of the oviduct. some peripheral neurons contained an abundance of neurosecretory granules that ranged in size from 32 to 180 nm in diameter. no ...19968667400
are stable flies (diptera: stomoxyinae) vectors of trypanosoma vivax in the central african republic?the epidemiology of trypanosoma vivax infections was studied at a riverside site in the ouro-djafoun livestock area situated in the central african republic during the period between july 1991 and july 1992. this paper examines the possibility that stable flies (diptera: stomoxyinae) were also vectors of this trypanosome species in a non-cyclic way. previous studies have revealed that the usual cyclic transmission by the tsetse fly glossina fuscipes fuscipes was probably not the only transmissio ...19968721295
skin lesions in dogs, horses and calves caused by the stable fly stomoxys calcitrans (l.) (diptera: muscidae).specific skin lesions caused by stomoxys calcitrans on the feeding sites of different species are described. skin lesions appeared on dogs, horses and calves following bites of stable flies. necrotic dermatitis was observed in 32 dogs of various breeds at the tip of the ears. exudative dermatitis appeared on the legs of 45 adult horses and dermatitis was diagnosed in the "hair whirlpools" on the backs of 18 white calves.19958734229
toxic effect of ethanolic extract of nerium oleander (apocynaceae) leaves against different developmental stages of muscina stabulans (diptera-muscidae).nerium oleander (apocynaceae) is evergreen shrubs widely used for ornamental purpose in mediterranean region. the present investigation, revealed for the first time the insecticidal effect of ethanolic extract from leaves of this plant against 2nd instar larvae of the medically important false stable fly muscina stabulans (diptera: muscidae). lc50 of the extract was 113.66 ppm. this dose delayed larval and pupal duration suppressed oviposition and decreased adult longevity of the survivors. morp ...19968754654
an immunocytochemical investigation of trypsin secretion in the midgut of the stablefly, stomoxys calcitrans.musca domestica trypsin antibody cross-reacts with polypeptide bands of m(r) 25,000 and 30,000 showing proteolytic activity from stomoxys calcitrans midgut extracts. secretory granules from the main enzyme-secreting region, the opaque zone, stained heavily with the trypsin antibody in both unfed and blood-fed flies. heterogeneous staining of granules suggests the unequal distribution of trypsin in secretory granules. this is also consistent with the occurrence of non-parallel secretion, which is ...19968763163

phenylpropanoids as attractants for adult stomoxys calcitrans (diptera:muscidae).rate of capture of stable flies, stomoxys calcitrans (l.), on phenylpropanoid-baited and unbaited sticky traps was determined in tests conducted in a corn field and in grasses adjacent to a dairy farm. phenylpropanoid compounds significantly increased capture in 2 of 4 tests in corn. captures were highest with 3-phenyl-1-propanol, followed closely by hydrocinnamaldehyde (3-phenyl-1-propanal), and more distantly by cinnamyl alcohol. both sexes were trapped, although males predominated approximate ...19968840698
scheduled sanitation to reduce stable fly (diptera: muscidae) populations in beef cattle feedlots.sanitation has been long recommended as a means of reducing stable fly, stomoxys calcitrans (l.), populations at cattle feedlots, but there is little published research to support this recommendation. in each of the 2 yr of this study, 4 feedlots received complete sanitation and 4 feedlots received no cleaning. the objective was to have the initial cleaning done before 1 june and then to reclean as needed every 2 wk thereafter. the feedlots that were cleaned had significantly fewer flies than th ...19968934824
comparison of core sampling and pupal traps for monitoring immature stable flies and house flies (diptera: muscidae) in beef feedlot pens.core samples and cylindrical pupal traps were used to monitor immature stages of the stable fly, stomoxys calcitrans (l.), and house fly, musca domestica l., from 5 sample areas in beef feedlot pens: the feed apron-soil interface, the back fence, the side (pen dividing) fence, the mound, and the general lot. one feedlot was sampled during 1986, two feedlots were sampled in 1987, and three samples were taken at random from each sample area on each sample date. core samples showed that both popula ...19968934827
calculating economic injury levels for stable flies (diptera:muscidae) on feeder heifers.a procedure for calculating the economic injury levels for stable flies, stomoxys calcitrans (l.), on feeder heifers was developed from reduction of average daily weight gain-stable fly population level data in 8 independent replicated experiments over 17 yr. a negative exponential was fitted to the data using nonlinear regression. regression coefficients were then used to derive a simple predictive equation for calculating the economic injury level in relation to cost of controlling stable flie ...19979071886
pupal parasitoids (hymenoptera:pteromalidae) of filth flies (diptera:muscidae, calliphoridae) breeding in refuse and poultry and livestock manure in south korea.five species of hymenopterous parasitoids were found parasitizing pupae of house flies, musca domestica l., in poultry and livestock facilities, refuse dump sites, and garbage dumpsters: spalangia nigroaenea curtis, s. nigra (latrielle), muscidifurax raptor girault & sanders, pachycrepoideus vindemiae (rondani), and nasonia vitripennis (walker). four hymenopterous parasitoids (s. nigroaenea, s. nigra, m. raptor and p. vindemiae) were recovered from the pupae of stable flies, stomoxys calcitrans ...19979086716
transcriptional expression of a putative tachykinin-like peptide receptor gene from stable fly.stkr is a 4118 bp clone from a stable fly, stomoxys calcitrans, cdna library which encodes a protein with significant amino acid identity to tachykinin-like peptide receptors. ribonuclease protection assays and rt-pcr were utilized to examine the transcriptional expression of stkr from various life stages of the stable fly. stkr expression was detectable in all stages, but was most abundant in isolated adult fly gut and lowest in developing embryos.19979114446
susceptibility of stable flies (diptera:muscidae) from southeastern nebraska beef cattle feedlots to selected insecticides and comparison of 3 bioassay techniques.insecticide susceptibility of field populations of stable flies, stomoxys calcitrans (l.), was assayed using 3 exposure techniques: treated filter papers, treated glass petri dishes, and topical applications. both topical applications and residual exposure to treated glass surfaces were suitable for testing susceptibility of stable flies to permethrin, stirofos, or methoxychlor. residues on filter papers yielded inconsistent results with stirofos and methoxychlor. significant concentration-morta ...19979145029

importance of supercooling points in the overwintering of the horn fly and stable fly (diptera:muscidae).supercooling points were determined for eggs, 3rd instars, pupae, newly emerged unfed adults and 3-d-old engorged laboratory reared adults of haematobia irritans (l.) and stomoxys calcitrans (l.). wild nondiapausing and diapausing pupae of h. irritans also were tested. mean supercooling points ranged from -28.0 degrees c for h. irritans eggs to -6.8 degrees c for h. irritans larvae. mean supercooling points of all h. irritans developmental stages were lower than those of comparable s. calcitrans ...19979220676
observations on the mite fauna associated with adult stomoxys calcitrans in the u.k.adult females of the blood-sucking muscid stomoxys calcitrans sampled between june and september 1993 from a cattle farm (n = 839) and from a pig farm (n = 542) in north-west england were examined for mites. twelve species of mites from ten families and three orders were identified as follows. in the prostigmata, eryenetes sp., family ereynetidae and pediculaster mesembrinae, family pygmephoridae. in the astigmata, procalvolia zacheri family saproglyphidae, acarus farris, family acaridae, bonomo ...19979226646
some morphological aspects of the mouthparts of italian blood-sucking muscids (diptera, stomoxyinae).scanning electron microscopy (sem) observations on the mouthparts of four species of blood-sucking muscid symbovine flies (stomoxys calcitrans linnaeus, haematobia irritans linnaeus, h. titillans bezzi, and haematobosca stimulans meigen) are described. the morphology of some structures (haustellum, prestomal teeth and petiolate blades) is compared in order to draw attention to those features involved in the feeding process on the hosts.19969257341
midgut-specific immune molecules are produced by the blood-sucking insect stomoxys calcitrans.we have cloned and sequenced two defensins, smd1 and smd2, from anterior midgut tissue of the blood-sucking fly stomoxys calcitrans. the dna and n-terminal protein sequences suggest both are produced as prepropeptides. smd1 differs from the classic defensin pattern in having an unusual six-amino acid-long n-terminal sequence. both smd1 and smd2 have lower pi points and charge than insect defensins derived from fat body/hemocytes. northern analysis shows both of these defensin molecules are tissu ...19979326639
stable fly, stomoxys calcitrans, mouthpart removal influences stress and anticipatory responses in mice.biting fly attack induces a variety of stress and anxiety related changes in the physiology and behaviour of the target animals. significant reductions in pain, or more appropriately, nociceptive sensitivity (latency of a foot-lifting response to an aversive thermal stimulus), are evident in laboratory mice after a 1 h exposure to stable flies, stomoxys calcitrans. the role of the various components of biting fly attack in the development of this stress-induced reduction in pain sensitivity (ana ...19979430107
population profile of stable flies (diptera: muscidae) caught on alsynite traps in various feedlot habitats.cylindrical traps made from alsynite fiberglass were placed in 4 habitats in a confined cattle feedlot environment from 2 may to 30 october 1996 to evaluate abundance, sex ratio, physiological age structure, and blood-fed status of trapped adult stable flies, stomoxys calcitrans (l.). significantly more stable flies were caught on the trap located between host cattle and trees. the abundance of stable flies decreased geometrically with increasing distance from the host cattle in the open area. t ...19989495090
relationships between temperature and life-history parameters of stomoxys calcitrans (diptera: muscidae).relationships between temperature and life history parameters were determined for the stable fly, stomoxys calcitrans (l.). median immature developmental times ranged from > 60 d at 15 degrees c to < 12 d at 30 degrees c, with minimum time at 30.6 degrees c. egg survival decreased from 0.98 at 15 degrees c to 0.91 at 20 degrees c, then increased to 0.98 at 35 degrees c. larval survival ranged from 0.83 at 20 degrees c to 0.65 at 35 degrees c, and pupal survival ranged from 0.93 at 20 degrees c t ...19989538570
synthesis and endectocidal activity of novel 1-(arylsulfonyl)-1-[(trifluoromethyl)sulfonyl]methane derivatives.we have recently synthesized a series of novel disulfonylmethane compounds that have shown anthelmintic and insecticidal (endectocidal) activity. several analogues have shown activity against the internal nematode haemonchus contortus. in sheep studies, these analogues have shown 100% control of this internal parasite at a 10 mg/kg rate. in vitro activity against the biting flies, stomoxys calcitrans and haematobia irritans, has been observed at rates as low as 25 and 2.3 ppm, respectively. only ...19989544209
pruritus and dermal response to insect antigens in sheep infested with bovicola ovis.this study examined the relationships among louse density, pruritus and dermal response to insect antigens in sheep infested with bovicola ovis. polypay and columbia ewes were allocated to two groups, infested and naive, and louse densities and pruritus were monitored for 15 months. ten months after the initial infestation, all sheep were tested for hypersensitivity on the midside and ears by intradermal injection of soluble extracts of b. ovis, stomoxys calcitrans and musca autumnalis. the area ...19989559360
cloning, sequencing, temporal expression and tissue-specificity of two serine proteases from the midgut of the blood-feeding fly stomoxys calcitrans.using highly degenerate, serine-protease-specific pcr primers on a midgut-specific cdna library it was estimated that a minimum of 24 independent serine proteases were expressed in the midgut of stomoxys calcitrans. the relative abundance of these 24 independent serine proteases has been estimated by restriction analysis of pcr products, showing that 69% fall into six almost equally abundant groups. two highly abundant serine protease cdnas (ssp1 and ssp2) were isolated and sequenced. they encod ...19989660182
serum and skin surface antibodies and their associations with sheep biting lice, bovicola ovis, on experimentally infested sheep.the sheep biting louse (bovicola ovis) feeds superficially on the skin of sheep but appears to stimulate an immune response. in this study we examined the association between louse infestation and serum and skin surface antibodies. louse numbers were monitored on experimentally infested polypay and columbia ewes for two years and on their lambs in the second year. serum and skin wash samples were tested for antibodies to soluble extracts of b. ovis, stomoxys calcitrans and musca autumnalis by en ...19989737599
sex differences in opioid and n-methyl-d-aspartate mediated non-opioid biting fly exposure induced analgesia in deer mice.there is evidence for sex differences in responses to noxious stimuli and in the expression and mediation of analgesia. in particular, results of investigations with swim stress and the more ethologically appropriate stress of predator odor exposure have suggested sex differences in n-methyl-d-aspartate (nmda) receptor system involvement in the mediation of analgesia. whether or not this sex difference generalizes to other environmental stressors is, however, not clear. biting flies are a natura ...19989766834
releases of spalangia nigroaenea and muscidifurax zaraptor (hymenoptera: pteromalidae) increase rates of parasitism and total mortality of stable fly and house fly (diptera: muscidae) pupae in illinois cattle feedlots.weekly releases of spalangia nigroaenea curtis and muscidifurax zaraptor kogan & legner from may through august of 1991-1993 at small, owner-operated cattle feedlots in illinois provided weekly emergence of 100-300 parasitoids of each species per feedlot animal. in assessments based on fly and parasitoid emergence from > 47,000 stable fly and house fly puparia collected during the 3-yr period, total stable fly mortality was greater in lots where releases were made (60.7%) than in paired, untreat ...19989805499
