| isolation of arboviruses from culicoides midges (diptera: ceratopogonidae) in colorado during an epizootic of vesicular stomatitis new jersey. | an arbovirus survey was conducted in colorado and utah during an epizootic of vesicular stomatitis new jersey (vsnj) that occurred in the western united states in 1982-1983. from 120,422 insect specimens assayed, 106 viruses were isolated. four were rhabdoviruses (vsnj), three were orbiviruses (bluetongue serotype-11), 92 were bunyamwera group (65 main drain and 27 lokern), and seven were simbu group (buttonwillow) bunyaviruses. culicoides spp. accounted for 105 viral isolates (c. (selfia) spp., ... | 1990 | 2167371 |
| vector competence of select black fly species for vesicular stomatitis virus (new jersey serotype). | black flies collected from southern arizona were evaluated for their vector competence to the oaxaca and camp verde isolates of vesicular stomatitis virus (new jersey serotype) (vsv-nj). the camp verde isolate is the index isolate of the 1982-1983 vsv-nj epizootic that infected humans and livestock in 14 western states. previous experiments have shown that colonized simulium vittatum females are competent laboratory vectors of both virus isolates. however, under controlled laboratory conditions, ... | 1997 | 9242316 |
| suppression of mosquito (diptera: culicidae) and black fly (diptera: simuliidae) blood feeding from hereford cattle and ponies treated with permethrin. | the blood feeding of mosquitoes and black flies from hereford cattle and ponies treated with commercial formulations of permethrin was evaluated using an animal enclosure trap sample system that allowed comparison of insect blood-feeding levels between treated and nontreated animals. blood feeding of both aedes dorsalis meigen and a. melanimon dyar from heifers treated with pour-on concentrate and whole body spray treatments was reduced significantly by 79-88% at 4 d posttreatment, with apparent ... | 2001 | 11580047 |
| hematophagous diptera collected from a horse and paired carbon dioxide-baited suction trap in southern california: relevance to west nile virus epizootiology. | hematophagous diptera landing on a horse were removed by vacuum, and their numbers were related to a paired carbon dioxide-baited suction trap at three locations in southern california where west nile virus activity was high during the preceding year. insects collected from the horse included mosquitoes (nine species), biting midges (culicoides sonorensis wirth & jones), and black flies (simulium bivittatum malloch). mosquitoes were predominantly collected from the head, crest, withers, neck, ch ... | 2008 | 18283951 |
