habitat preference of coastal culicoides spp. at yankeetown, florida.	larval habitats of salt marsh culicoides spp. were delineated. twenty-six habitat categories were equally sampled. four broad physiographic zones were identified from aerial photographs and ground surveys. two salt marsh zones were identified and separated on the basis of differences in plant cover type and distribution, number and conformation of islands, tidal creeks and ponds, and substrate structure. the other 2 zones were an extensive brackish-freshwater marsh and an upland area dominated b ...	1988	3225565
host-seeking activity of culicoides spp. (diptera: ceratopogonidae) near yankeetown, florida.	the diel, seasonal, and lunar host-seeking periodicity of culicoides mississippiensis, c. floridensis, c. barbosai, and c. furens was studied near yankeetown, florida. culicoides mississippiensis was the only species active during all seasons. significantly more (p less than 0.05) individuals sought a blood meal when the moon was full than when the moon was in some other phase. culicoides floridensis, the species with the shortest wing length, did not attack when the wind speed exceeded 9 km/h, ...	1988	3225567
trajectory analysis and bluetongue virus serotype 2 in florida 1982.	examination of northern hemisphere synoptic charts and computation of backward trajectories indicated that culicoides infected with bluetongue virus serotype 2 could have been carried on the wind and brought the virus to florida on the afternoon of august 19, 1982 after leaving northern cuba the previous evening. flight would have occurred at a height of 1-1.5 km at temperatures of 15-17 degrees c. the distance of 500 km from northern cuba to ona would have been covered in 20 h at an average spe ...	1989	2536578
carbon dioxide and 1-octen-3-ol as mosquito attractants.	interval suction traps were used to study the attractant effect of co2 and 1-octen-3-ol on trap catches of mosquito populations at 2 different locations in florida. there was no significant increase in the numbers of mosquitoes caught when the concentration of co2 was increased from 200 to 1,000 cc/min. one-octen-3-ol used by itself attracted mosquitoes in numbers similar to co2 released at 200 cc/min. one-octen-3-ol and co2 acted synergistically in attracting significantly greater numbers of ae ...	1989	2573687
bivens arm virus: a new rhabdovirus isolated from culicoides insignis in florida and related to tibrogargan virus of australia.	during field studies in 1981 on the transmission of bluetongue viruses in ruminants in florida, a virus was isolated from culicoides insignis collected near water buffalo (bubalus bubalis) recently imported from trinidad. electron microscopy showed that this isolate, for which the name bivens arm virus is proposed, has rhabdovirus morphology. serologic comparisons were made with recognized rhabdoviruses from terrestrial vertebrates and hematophagous arthropods. indirect fluorescent antibody, com ...	1989	2650459
equine culicoides hypersensitivity in florida: biting midges aspirated from horses.	nine species of culicoides were aspirated from horses in florida during the second phase of a study of equine culicoides hypersensitivity (chs). approximately 90% of the 2933 midges were culicoides insignis lutz, 4% were c.stellifer (coquillett), 3% were c.niger root and hoffman, 2% were c.alachua jamnback and wirth and the remaining 1% included c.venustus hoffman, c.scanloni wirth and hubert, c.lahillei iches (= c.debilipalpis lutz), c.pusillus lutz, and c.edeni wirth and blanton. culicoides we ...	1990	2133005
seroepidemiology of bivens arm virus infections of cattle in florida, st. croix and puerto rico.	bivens arm virus (bav) is a newly discovered rhabdovirus infecting cattle and water buffalo in florida. the virus is classified as a member of the tibrogargan group, members of which have hitherto been found only in australasia. they are considered to be transmitted by culicoides species. bivens arm virus was first isolated from culicoides insignis which suggests that bav is also transmitted by this genus. a serological survey of two small groups of cattle raised in st. croix and puerto rico, in ...	1991	1871952
evaluation of culicoides insignis (diptera: ceratopogonidae) as a vector of bluetongue virus.	based upon epidemiological evidence, culicoides insignis lutz is a probable biological vector of bluetongue viruses (btv) in south florida, the caribbean region and central america. the vector potential of this species for btv was evaluated in the laboratory in a series of experiments using insects caught in the field. although there was great variation in the percentage of flies that fed from any one catch, it was demonstrated that c. insignis became infected after membrane feeding on a mixture ...	1992	1325085
sympatry in the culicoides variipennis complex (diptera: ceratopogonidae): a taxonomic reassessment.	we report sympatry among larval populations of the culicoides variipennis complex in widespread and diverse aquatic habitats throughout the united states. six sites in california, nevada, new mexico, and texas were co-inhabited by c. v. occidentalis and c. v. sonorensis, whereas 8 sites in florida, georgia, louisiana, maryland, and texas were co-occupied by c. v. sonorensis and c. v. variipennis. no intermediate forms were identified either electrophoretically or morphologically in adults reared ...	2000	15218909
an iridescent virus and a microsporidium in the biting midge culicoides barbosai from florida.	an iridescent virus and a microsporidium (nosema sp.) were found infecting larvae of the biting midge culicoides barbosai collected in boynton beach, palm beach county, florida. larvae were extracted from mud collected weekly during a 22-month period from march 1998 to december 1999. virus-infected larvae were present in 4 collections made in march, april, and may 1998 and the average infection level was 4.7% (range 2.3-7.1%). the virus infected the fat body and produced an iridescent blue color ...	2002	12083356
adult biting midge response to trap type, carbon dioxide, and an octenol-phenol mixture in northwestern florida.	the efficacy of centers for disease control, abc pro, and counterflow geometry (cfg) mosquito suction traps to sample populations of adult culicoides was investigated in northwestern florida. these traps were baited either with a 4:1:8 mixture of octenol, 3-n-propylphenol, and 4-methylphenol alone or in combination with carbon dioxide (co2). control traps were operated without the octenol-phenol mixture or co2. four species, in order of descending abundance, were collected in all traps regardles ...	2002	12322947

evaluation of a novel removal trap system to reduce biting midge (diptera: ceratopogonidae) populations in florida backyards.	a removal trapping method that employed individual lure-baited insect suction traps for the reduction of adult biting midges (culicoides spp.) was evaluated in a coastal residential neighborhood of northwestern florida during 2000. six backyards were used in the study. lure-baited traps consisted of one abc pro insect suction trap (fitted with a 30 by 30-mesh polyester screen bag) baited with carbon dioxide (500 ml/min) and a 4:1:8 mixture of 1 octen-3-ol, 3-n-propylphenol, and 4-methylphenol (5 ...	2003	12831125
the effectiveness of the mosquito magnet trap for reducing biting midge (diptera: ceratopogonidae) populations in coastal residential backyards.	this study evaluated the effectiveness of single mosquito magnet' traps to consistently reduce biting midge populations in a coastal northwest florida residential neighborhood. midge abundance from 5 backyards, each with a mosquito magnet trap, was compared with 3 backyards without traps (controls). midge populations were sampled once weekly for 24 h in each backyard by using a centers for disease control (cdc) suction trap baited with carbon dioxide. in addition, midge accumulations from mosqui ...	2005	16033125
evaluation of two commercial traps for the collection of culicoides (diptera: ceratopogonidae).	two types of commercial propane-powered traps, mosquito magnet (mm) (american biophysics corporation) mm-freedom (freedom) and mm-liberty plus (liberty plus), were evaluated for the collection of culicoides. trap preference and seasonal characteristics for the 3 major species, culicoides furens, culicoides barbosai, and culicoides mississippiensis, were recorded from july 7, 2005, to july 24, 2006. over 35 million culicoides were captured during our study. when species were evaluated separately, ...	2008	18666534
