| effect of the landscape and climate on the distribution of blood-sucking mosquitoes in murmansk province. | according to its orographic characteristics and climate the murmansk region represents a special landscape area of the atlantic-arctic zone with its peculiar zoogeographic characters. this specificity is clearly seen in the distribution of 19 species of bloodsucking mosquitoes over the above territory. abundant and widely encountered are only two species, aedes punctor and ae. communis. 9 species, culiseta alaskaensis, c. bergrothi, aedes pullatus, ae. excrucians, ae. pionips, ae. hexodontus, ae ... | 1977 | 19722 |
| isolation of jamestown canyon and snowshoe hare viruses (california serogroup) from aedes mosquitoes in western massachusetts. | three isolates of jamestown canyon virus and one isolate of snowshoe hare virus (california serogroup) were obtained from adult aedes females collected in western massachusetts in 1982. jamestown canyon virus was isolated from aedes abserratus/punctor once, and from aedes intrudens twice. snowshoe hare virus was isolated from aedes stimulans group mosquitoes. la crosse encephalitis (lac) virus was not isolated from 1,552 adult aedes triseriatus, nor from 22,557 aedes triseriatus larvae. however, ... | 1993 | 8350066 |
| mosquito species richness, composition, and abundance along habitat-climate-elevation gradients in the northern colorado front range. | we exploited elevation gradients (1,500-2,400 m) ranging from plains to montane areas along the poudre river and big thompson river in the northern colorado front range to determine how mosquito species richness, composition, and abundance change along natural habitat-climate-elevation gradients. mosquito collections in 26 sites in 2006 by using co2-baited cdc light traps yielded a total of 7,136 identifiable mosquitoes of 27 species. commonly collected species included aedes vexans (meigen) (n ... | 2008 | 18714885 |
| repellency of hydrogenated catmint oil formulations to black flies and mosquitoes in the field. | the essential oil of catmint, nepeta cataria l., was hydrogenated to yield an oil enriched in dihydronepetalactone (dhn) diastereomers, termed. this material was used for the preparation of liquid alcohol-based and lotion formulations. the efficacy of these formulations as repellents was tested after application to human test subjects at two locations in the united states: maine and florida. in maine, data on repellency of the hydrogenated catmint oil formulations toward black flies (simulium de ... | 2008 | 19058632 |
| detection of francisella tularensis in alaskan mosquitoes (diptera: culicidae) and assessment of a laboratory model for transmission. | tularemia is a zoonotic disease caused by the category a bioterrorism agent francisella tularensis. in scandinavia, tularemia transmission by mosquitoes has been widely cited in the literature. we tested >2,500 mosquitoes captured in alaska and found francisella dna in 30% of pooled samples. to examine the potential for transmission of francisella by mosquitoes, we developed a mosquito model of francisella infection. larvae of anopheles gambiae giles and aedes aegypti (l.) readily ingest f. tula ... | 2010 | 20695280 |
| francisella tularensis subspecies holarctica occurs in swedish mosquitoes, persists through the developmental stages of laboratory-infected mosquitoes and is transmissible during blood feeding. | in sweden, mosquitoes are considered the major vectors of the bacterium francisella tularensis subsp. holarctica, which causes tularaemia. the aim of this study was to investigate whether mosquitoes acquire the bacterium as aquatic larvae and transmit the disease as adults. mosquitoes sampled in a swedish area where tularaemia is endemic (örebro) were positive for the presence of f. tularensis deoxyribonucleic acid throughout the summer. presence of the clinically relevant f. tularensis subsp. h ... | 2013 | 24057273 |
| synthesis and evaluation of the naturally occurring phototoxin, alpha-terthienyl, as a control agent for larvae of aedes intrudens, aedes atropalpus (diptera: culicidae) and simulium verecundum (diptera: simuliidae). | | 1985 | 3973205 |
| efficacy of the plant phototoxinα-terthienyl againstaedes intrudens and effects on nontarget organisms. | the botanical phototoxin, α-terthienyl (α-t) was spray applied to natural or artificial pools containing mosquito (aedes intrudens) larvae and nontarget invertebrates (caddisfly, damselfly, midge, shrimp,daphnia, snail) and one vertebrate (trout) at concentrations varying from 0.01 to 1 kg/hectare, under field and laboratory conditions. all field-treated nontarget invertebrates survived α-t treatment better thana. intrudens which can be controlled at doses as low as 0.01 kg/hectare within one we ... | 1986 | 24306977 |
