| 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 ... | 1996 | 8667400 |
| 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 ... | 1996 | 8721295 |
| 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 ... | 1997 | 9326639 |
| 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 ... | 1997 | 9430107 |
| 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 ... | 1997 | 9071886 |
| 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 ... | 1997 | 9086716 |
| 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. | 1997 | 9114446 |
| 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 ... | 1997 | 9145029 |

| 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 ... | 1997 | 9220676 |
| 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 ... | 1997 | 9226646 |
| cycling of ecdysteroid levels in adult female stable flies, stomoxys calcitrans in relation to blood feeding. | the effect of blood-feeding on total and specific immunoreactive ecdysteroids in stomoxys calcitrans adult females was examined following the fourth and fifth blood meals when total whole body and hemolymph ecdysteroids showed a dramatic increase in the titer. in general, for both total and specific immunoreactive ecdysteroids that included highly polar material, 20,26-dihydroxyecdysone, 20-hydroxyecdysone and ecdysone, there were clear differences between the effects of the fourth and fifth mea ... | 1997 | 12770457 |
| natriuretic and depolarizing effects of a stable fly (stomoxys calcitrans) factor on malpighian tubules. | a two-step hplc purification procedure resulted in a factor from the stable fly that depolarizes the lumen-negative transepithelial voltage (v(t)) of the adult stable fly malpighian tubule. when applied to tubules of the female mosquito, aedes aegypti, this factor partially mimics the electrophysiological actions of the mosquito natriuretic factor (mnf). it also selectively increases active transepithelial na transport by the mosquito malpighian tubule. the blood meal causes a transient increase ... | 1997 | 12770470 |
| 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 ... | 1998 | 9495090 |
| 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 ... | 1998 | 9538570 |
| 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 ... | 1998 | 9544209 |
| 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 ... | 1998 | 9559360 |
| 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 ... | 1998 | 9660182 |
| 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 ... | 1998 | 9737599 |
| 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 ... | 1998 | 9766834 |
| 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 ... | 1998 | 9805499 |
| management of ectoparasites with biological control organisms. | biological control is not a new concept, but for many reasons it is gaining interest for control of livestock ectoparasites. these reasons will be discussed, both from a political view and from environmental and economic views. the us government has vowed to reduce pesticide use by the year 2000, but other forces may drive this change even faster. pesticide costs are high, and efficacy against some pests is questionable. also, many producers are concerned about the environment, and are anxious t ... | 1999 | 10048827 |
| ultrastructural localization of unique neurosecretory granules in the corpora cardiaca of the stable fly, stomoxys calcitrans, and the tsetse fly, glossina morsitans. | ultrastructural analysis of the corpora cardiaca of the stable fly, stomoxys calcitrans, and the tsetse fly, glossina morsitans, revealed the presence of elementary neurosecretory granules (eng) unique to the intrinsic neurosecretory cells (inc) of these species. in addition to electron-dense spheres, the inc of the corpus species. in addition to electron-dense spheres, the inc of the corpus cardiacum of the stable fly contain electrondense angular granules, either square or rectangular in shape ... | 1999 | 10322625 |
| rearing stable fly larvae (diptera: muscidae) on an egg yolk medium. | the growth and survival of stomoxys calcitrans (l.) larvae on egg yolk medium inoculated with bacteria isolated from a colony of stable flies was evaluated. five species of bacteria--acinetobacter sp., aeromonas sp., empedobacter breve (holmes & owen), flavobacterium odoratum stutzer, and serratia marcescens bizio--were identified according to fatty acid profiles using a microbial identification system. larvae failed to develop on uninoculated plates, confirming that bacteria are required to com ... | 1999 | 10337112 |
| skin lesions and cattle hide damage from haematobia irritans infestations. | the horn fly haematobia irritans l. (diptera: muscidae) has recently spread to argentina and uruguay and is believed to cause damage to cattle hides. four groups of ten holstein steers each were maintained for 58 weeks under different infestation levels with h. irritans to determine if it was the cause of this problem. hides (chrome tanned) from steers maintained under minimum infestation level had 4.7 +/- 3.8% of the area damaged. maintaining the steers under low h. irritans level for the last ... | 1999 | 10514060 |
| evaluation of various substances to increase adult stomoxys calcitrans (diptera: muscidae) collections on alsynite cylinder traps in north florida. | during 1993-1995, field studies evaluated various volatile substances to increase the catch of adult stable flies, stomoxys calcitrans l., on adhesive-coated translucent fiberglass (alsynite) cylinder traps. dry ice, 1-octen-3-ol (referred to as octenol), acetone, 4:1:8 mixture of 1 octen-3-ol: 3-n-propylphenol: 4-methylphenol, and an eye gnat (hippelates) attractant were tested. using dry ice as a baseline, the latter 4 treatments also were considered as possible alternatives to carbon dioxide. ... | 1999 | 10534955 |
| the role of houseflies (musca domestica) in harbouring corynebacterium pseudotuberculosis in dairy herds in israel. | a study was conducted to assess the role of houseflies, musca domestica l. in harbouring corynebacterium pseudotuberculosis in dairy farms in israel. the bacterium was isolated in june 1993 from 40 wild houseflies which had fed on a lesion on a cow, and from 28 laboratory flies fed on contaminated milk from a cow infected with mastitis. the bacterium was recovered from the body surface of 10 flies (of a total of 160) 10 min after being dipped entirely in a bacterial broth. the bacterium was reco ... | 1999 | 10588012 |
| stable fly, house fly (diptera: muscidae), and other nuisance fly development in poultry litter associated with horticultural crop production. | poultry litter usage in horticultural crop production is a contributor to nuisance fly populations, in particular stable flies (stomoxys calcitrans l.) and house flies (musca domestica l.). extrapolation of adult emergence data suggests that approximately 1.5 million house flies and 0.2 million stable flies are emerging on average from every hectare of poultry litter applied as a preplant fertilizer for vegetable production in perth, western australia. to a lesser extent, sideband applications t ... | 1999 | 10633577 |
| porphyrins and related compounds as photoactivatable insecticides. 3. laboratory and field studies. | the exposure of populations of ceratitis capitata (fruit fly), bactrocera oleae (olive fly) and stomoxis calcitrans (house fly) to a bait containing mumolar concentrations of porphyrin-type photosensitizers resulted in a significant accumulation of the porphyrin by the insects and a consequent development of photosensitivity upon exposure to visible light. the photoinsecticidal activity appeared to increase with increasing hydrophobicity of the porphyrin molecule: thus, the amphiphilic dicationi ... | 2000 | 10687383 |
| age structure and abundance in populations of muscoid flies from a poultry facility in southeast brazil. | muscina stabulans, m. domestica, chrysomya putoria, c. megacephala and stomoxys calcitrans were the most abundant muscoid flies captured in a poultry facility in southeastern brazil. we examined the gonadotrophic profiles of the females caught at different sites and different times and found that mu. stabulans and m. domestica, the predominant species, presented similar gonadotrophic profiles only when captured on the manure under the cages, but very different and sometimes opposite gonadotrophi ... | 2000 | 10733750 |
| characterization of a receptor for insect tachykinin-like peptide agonists by functional expression in a stable drosophila schneider 2 cell line. | stkr is an insect g protein-coupled receptor, cloned from the stable fly stomoxys calcitrans. it displays sequence similarity to vertebrate tachykinin [or neurokinin (nk)] receptors. functional expression of the cloned stkr cdna was obtained in cultured drosophila melanogaster schneider 2 (s2) cells. insect tachykinin-like peptides or "insectatachykinins," such as locusta tachykinin (lom-tk) iii, produced dose-dependent calcium responses in stably transfected s2-stkr cells. vertebrate tachykinin ... | 2000 | 10800964 |
| sunlight-activated insecticides: historical background and mechanisms of phototoxic activity. | several photosensitizing agents, which are activated by illumination with sunlight or artificial light sources, have been shown to be accumulated in significant amounts by a variety of insects when they are administered in association with suitable baits. the subsequent exposure of such insects to uv/visible light leads to a significant drop in survival. of the photosensitizers tested so far, xanthenes (e.g. phloxin b) and porphyrins (e.g. haematoporphyrin) appear to be endowed with the highest ... | 2000 | 10899458 |
| transformation of stomoxys calcitrans with a hermes gene vector. | the ability of the hermes transposable element to function as a germ line transformation vector was tested in the stable fly, stomoxys calcitrans. plasmid-based transposable element mobility assays indicated moderate mobility of hermes in this species. germline transformants were created using a hermes element containing the enhanced green fluorescent protein (egfp) under the regulatory control of the promoter from actin5c gene of drosophila melanogaster. approximately 4% of the fifty-five adult ... | 2000 | 11029672 |
| behavioral response of stomoxys calcitrans (diptera: muscidae) to conspecific feces and feces extracts. | the attraction response of stomoxys calcitrans (l.) to its own feces was evaluated in a triple cage olfactometer. both time- and concentration-response relationships were obtained for female s. calcitrans exposed to cellulose sponges impregnated with fresh fly feces or filter papers treated with chloroform:methanol extracts of fresh fly feces in 6-min tests. attraction to feces collected on cellulose sponges decreased as the air flow increased. feces collected on cellulose sponges and held for 2 ... | 2000 | 11126557 |
| evaluation of stomoxys calcitrans (diptera: muscidae) behavioral response to human and related odors in a triple cage olfactometer with insect traps. | a triple cage olfactometer provided with insect traps was used for evaluating behavioral responses of stomoxys calcitrans (l.) females to human skin and breath, co2, and l-lactic acid analogs. after demonstrating there were no significant differences caused by cage location or time of day, 3 sets of 3 olfactometer tests were performed in a day, every 2 h beginning at 0900 hours. when a human hand was used as attractant, the attraction (expressed as percentage of trapped flies) increased as a fun ... | 2000 | 15535569 |
| molecular characterization of two serine proteases expressed in gut tissue of the african trypanosome vector, glossina morsitans morsitans. | serine proteases are major insect gut enzymes involved in digestion of dietary proteins, and in addition they have been implicated in the process of pathogen establishment in several vector insects. the medically important vector, tsetse fly (diptera:glossinidiae), is involved in the transmission of african trypanosomes, which cause devastating diseases in animals and humans. both the male and female tsetse can transmit trypanosomes and both are strict bloodfeeders throughout all stages of their ... | 2001 | 11240636 |
| nmda-mediated social learning of fear-induced conditioned analgesia to biting flies. | although fear conditioning has received extensive neurobiological attention little is known about social learning whereby one individual may learn and acquire the fear responses of another. a 30 min exposure to intact biting flies (stable fly, stomoxys colcitrans l.) elicits in individual fly-naive mice analgesia and active self burying responses to avoid the flies. fly-naive observer mice that witnessed other demonstrator mice being attacked by biting flies exhibited analgesia and self-burying ... | 2001 | 11277559 |
| larvicidal activity of endectocides against pest flies in the dung of treated cattle. | cattle were treated with topical formulations of endectocides to assess the larvicidal activity of faecal residues against horn fly, haematobia irritans (l.), house fly, musca domestica l., and stable fly, stomoxys calcitrans (l.) (diptera: muscidae). in laboratory bioassays, doramectin, eprinomectin and ivermectin suppressed horn fly in dung of cattle treated at least 4 weeks previously and suppressed house fly and stable fly in dung of cattle treated 1-5 weeks previously. moxidectin suppressed ... | 2001 | 11297096 |
| effects of stable flies (diptera: muscidae) on weight gains of grazing yearling cattle. | differences in weight gains caused by stable flies, stomoxys calcitrans (l.), on grazing yearling steer/calves averaged 0.2 kg per steer in a 3-yr study on canyon range pastures in west central nebraska, stable fly numbers averaged 0.85 per front leg on treated calves and 3.64 per front leg on control calves. in 2 of the 3 yr after the grazing trials were completed, the calves were placed in a feedlot and fed a finishing ration. compensatory gain did not occur in the feedlot after the stable fly ... | 2001 | 11425037 |
| diptera as vectors of mycobacterial infections in cattle and pigs. | mycobacteria were isolated from 14 (4.5%) of 314 samples, containing 7791 adult diptera, which were collected in the czech republic and slovakia in 1997-2000. these flies were collected from three cattle herds with paratuberculosis, two pig herds with mycobacterial infections and one farm that kept both cattle and pigs and that did not have problems of mycobacterial infections. mycobacterium intracellulare was isolated from eristalis tenax linnaeus (diptera: syrphidae) captured from a pig herd. ... | 2001 | 11434556 |
| child neglect and forensic entomology. | close co-operation between forensic scientists, medico-legal doctors, and police forces made it possible to estimate not only the post-mortem interval but also the time since a child was neglected. on the skin surface under the diaper (anal-genital area), third instar larvae of the false stable fly muscina stabulans fallen, and the lesser house fly fannia canicularis l. were found. f. canicularis adults are attracted to both feces and urine. from the face, larvae of the bluebottle fly calliphora ... | 2001 | 11457624 |
| pharmacological characterization of stkr, an insect g protein-coupled receptor for tachykinin-like peptides. | stkr is a g protein-coupled receptor that was cloned from the stable fly, stomoxys calcitrans. multiple sequence comparisons show that the amino acid sequence of this insect receptor displays several features that are typical for tachykinin (or neurokinin, nk) receptors. insect tachykinin-related peptides, also referred to as "insectatachykinins," produce dose-dependent calcium responses in drosophila melanogaster schneider 2 cells, which are stably transfected with this receptor (s2-stkr). thes ... | 2001 | 11519074 |
| regulation of midgut defensin production in the blood-sucking insect stomoxys calcitrans. | the stomoxys midgut defensin (smd) family of genes are exclusively expressed in the anterior midgut of adult flies. their putative function is protection of the stored bloodmeal from microbial attack. smd genes are constitutively expressed, up-regulated in response to a bloodmeal and further up-regulated by immune stimulation per os but only in the presence of a bloodmeal not a sugar meal. smd genes are down-regulated in response to a systemic immune challenge. smd gene constructs transfected in ... | 2001 | 11903625 |
| diptera brachycera horse parasites in a stable/manège in northern italy. | the presence of tabanids and muscoid fly (diptera brachycera) parasites of horses in a stable/manège near verona (northern italy) is reported. tabanus quatuornotatus, t. glaucopis, t. exclusus, hybomitra muehlfeldi, haematopota pandazisi, stomoxys calcitrans and haematobia irritans were the blood-sucking species directly found on horses. musca domestica, ophyra sp. and fannia canicularis were the flies most frequently collected by sticky traps in the stable. | 2001 | 12402525 |
| occurrence of insect kinins in the flesh fly, stable fly and horn fly-mass spectrometric identification from single nerves and diuretic activity. | maldi-tof mass spectrometric analysis of single lateral abdominal nerves (lans) demonstrate the presence of the insect kinin musdo-k in the housefly musca domestica, and identify heretofore unknown insect kinins in two other dipteran species as musdo-k in the stable fly stomoxys calcitrans and horn fly haematobia irritans. the insect kinin native to the flesh fly neobellieria bullata is identified as drome-k. musdo-k and drome-k are identical save for the conservative substitution of ser for thr ... | 2002 | 12431726 |
| the dh gene of drosophila melanogaster encodes a diuretic peptide that acts through cyclic amp. | dh, the gene that encodes a crf-like peptide in drosophila melanogaster, is described. the product of this gene is a 44-amino-acid peptide (drome-dh(44)) with a sequence almost identical to the musca domestica and stomoxys calcitrans diuretic hormones. there are no other similar peptides encoded within the known drosophila genomic sequence. functional studies showed that the deduced peptide stimulated fluid production, and that this effect was mediated by cyclic amp in principal cells only: ther ... | 2002 | 12432004 |
| recombinant aequorin as a reporter for receptor-mediated changes of intracellular ca2+ -levels in drosophila s2 cells. | the bioluminescent ca(2+)-sensitive reporter protein, aequorin, was employed to develop an insect cell-based functional assay system for monitoring receptor-mediated changes of intracellular ca(2)(+)-concentrations. drosophila schneider 2 (s2) cells were genetically engineered to stably express both apoaequorin and the insect tachykinin-related peptide receptor, stkr. lom-tk iii, an stkr agonist, was shown to elicit concentration-dependent bioluminescent responses in these s2-stkr-aeq cells. the ... | 2002 | 12488971 |
| modulation of bovine lymphocyte response by salivary gland extracts of the stable fly, stomoxys calcitrans (diptera: muscidae). | the effect of salivary gland extract of the stable fly, stomoxys calcitrans (l), on bovine lymphocyte proliferation was determined, and antibody reactivity to salivary gland proteins was characterized in cattle exposed to stable flies. salivary glands were dissected from male and female flies (4-8 d after eclosion), and protein extracts were made by freeze-thaw cycles. salivary gland extract (sge, 1 and 5 microg) significantly inhibited mitogen-driven proliferation of bovine lymphocytes, compare ... | 2002 | 12495190 |
| attractiveness of beach ball decoys to adult stomoxys calcitrans (diptera: muscidae). | the attractiveness of inflated beach balls covered with adhesive and used as decoys to trap adult stable flies was investigated on florida panhandle beaches. decoys were painted either solid black, solid white, or a mixed pattern that consisted of three equally spaced white circles (20 cm diameter) on a solid black background. another set of decoys (referred to as plain) were unpainted and retained the manufacturer's original color scheme. the plain decoy consisted of a separate blue, yellow, an ... | 2002 | 11931245 |
| assessment of parasitism of house fly and stable fly (diptera: muscidae) pupae by pteromalid (hymenoptera: pteromalidae) parasitoids using a polymerase chain reaction assay. | the internal transcribed spacer (its) regions of the ribosomal dna of house flies, musca domestica l., the stable flies, stomoxys calcitrans (l.), and four parasitoid species in the genus muscidifurax (hymenoptera: pteromalidae) were characterized to develop a method based on the polymerase chain reaction (pcr) to better define the role of pteromalid parasitism of pupae of the house fly and stable fly. two parasitoid-specific primers were designed to anneal to the 5' end of the 5.8s rrna gene in ... | 2002 | 11931272 |
| comparsion of selected growth media for culturing serratia marcescens, aeromonas sp., and pseudomonas aeruginosa as pathogens of adult stomoxys calcitrans (diptera: muscidae). | stable flies, stomoxys calcitrans (l.), were orally infected with aeromonas sp., pseudomonas aeruginosa (schroeter), and serratia marcescens bizio that were cultured on egg-yolk media, nutrient broth, and fly egg media. aeromonas and serratia caused mortality when the bacteria were originally grown on egg-yolk medium. pseudomonas was equally lethal regardless of the media on which it was cultured. a wild isolate of aeromonas caused greater death than an isolate that had been passed through host ... | 2002 | 11931277 |
| association of midgut defensin with a novel serine protease in the blood-sucking fly stomoxys calcitrans. | using elisa we provide direct evidence that the midgut defensins of the blood-sucking fly stomoxys calcitrans are secreted into the gut lumen. we show that midgut defensin peptide levels increase up to fortyfold in response to a blood meal but not to a sugar meal. the data suggests the midgut defensin genes are post-transcriptionally regulated and that their function is protection of the stored blood meal from bacterial attack while it awaits digestion. using recombinant defensins produced in pi ... | 2002 | 12000638 |
| analysis of c-terminally substituted tachykinin-like peptide agonists by means of aequorin-based luminescent assays for human and insect neurokinin receptors. | aequorin-based assays for stable fly, stomoxys calcitrans, (stkr) and human (neurokinin receptor 1 (nk1), neurokinin receptor 2 (nk2)) neurokinin-like receptors were employed to investigate the impact of a c-terminal amino acid exchange in synthetic vertebrate ('fxglma') and invertebrate ('fx1gx2ra') tachykinin-like peptides. c-terminally (arg to met) substituted analogs of the insect tachykinin-related peptide, lom-tk i, displayed increased agonistic potencies in luminescent assays for human nk ... | 2002 | 12007570 |
