| studies on the possible role of cattle nuisance flies, especially hydrotaea irritans, in the transmission of summer mastitis in denmark. | the summer mastitis pathogens actinomyces pyogenes, peptococcus indolicus, bacteroides melaninogenicus ss. levii, fusobacterium necrophorum and streptococcus dysgalactiae were isolated from the polyphagous symbovine dipterans hydrotaea irritans (fallén) and morellia sp. caught around dairy heifers on pasture, but not from the haematophagous species haematobia irritans (l.), haematobosca stimulans (meigen), culicoides sp. and simulium sp. secretions from clinical cases of summer mastitis proved t ... | 1991 | 1773120 |
| [seasonal dynamics of synbovine flies (diptera: muscidae) during the grazing period in jarov]. | synbovine flies and the seasonal pattern of their occurrence were studied throughout the grazing period in the cattle pastures of the strakonice district. skufin's traps were used for catching the flies. the total number of dipterous insects caught during the series of trappings in two- to three-week intervals was 2096. the family muscidae (23 species) was represented most amply in the sample catches (musca autumnalis 65.9%, hydrotaea meteorica 20.4%, hydrotaea irritans 4.2%, haematobosca stimul ... | 1987 | 3125656 |
| insecticidal ear tags and sprays for the control of flies on cattle. | ear tags containing 8.5 per cent w/w cypermethrin gave almost complete control of the biting muscid, haematobosca stimulans. protection afforded against nuisance flies was more variable; generally a 70 to 80 per cent reduction of headfly, hydrotaea irritans, and a 60 to 70 per cent reduction of morellia simplex. ear tags containing 8.5 per cent fenvalerate also gave significant protection against biting and nuisance flies. spraying with 500 ppm cyhalothrin or 1000 ppm cypermethrin afforded compl ... | 1984 | 6474773 |
| flies associated with cattle in south west scotland during the summer months. | the sheep headfly, hydrotaea irritans, and morellia simplex were the species most frequently associated with cattle at pasture and comprised 69.01 per cent and 13.93 per cent, respectively, of the total fly collection made from grazing cattle. the most prevalent biting fly was haematobosca stimulans which comprised 4.46 per cent of the total catch. a few clegs, haematopota pluvialis, and horse flies, hybomitra distinguenda, were also recorded. a few of the headflies swarming around cattle entere ... | 1981 | 7244374 |
| variation in density of cattle-visiting muscid flies between danish inland pastures. | the density of cattle-visiting flies (muscidae) and the load of black-flies (simulium spp.) were estimated in twelve and eighteen inland pastures in denmark in 1984 and 1985 respectively. no differences in the geographical distribution pattern of the predominant cattle-visiting muscidae were recorded, whilst the relative abundance and density of the species and the total fly-load varied considerably between pastures. in most cases the mean loads of haematobia irritans (l.) and hydrotaea irritans ... | 1993 | 8435484 |
| 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. | 1996 | 9257341 |
