specific detection of the floodwater mosquitoes aedes sticticus and aedes vexans dna in predatory diving beetles.floodwater mosquitoes (diptera: culicidae) are associated with periodically flooded wet meadows, marshes, and swamps in floodplains of major rivers worldwide, and their larvae are abundant in the shallow parts of flooded areas. the nuisance caused by the blood-seeking adult female mosquitoes motivates mosquito control. larviciding with bacillus thuringiensis israelensis is considered the most environmentally safe method. however, some concern has been raised whether aquatic predatory insects cou ...201524895318
potential for canadian mosquitoes to transmit rift valley fever virus.the rapid spread of west nile viral activity across north america since its discovery in 1999 illustrates the potential for an exotic arbovirus to be introduced and become widely established across north america. rift valley fever virus (rvfv) has been responsible for large outbreaks in africa that have resulted in hundreds of thousands of human infections and major economic disruption due to loss of livestock and to trade restrictions. however, little is known about the potential for mosquitoes ...201122329267
host reproductive phenology drives seasonal patterns of host use in mosquitoes.seasonal shifts in host use by mosquitoes from birds to mammals drive the timing and intensity of annual epidemics of mosquito-borne viruses, such as west nile virus, in north america. the biological mechanism underlying these shifts has been a matter of debate, with hypotheses falling into two camps: (1) the shift is driven by changes in host abundance, or (2) the shift is driven by seasonal changes in the foraging behavior of mosquitoes. here we explored the idea that seasonal changes in host ...201121408172
the present distribution and predicted geographic expansion of the floodwater mosquito aedes sticticus in sweden.the mass emergence of floodwater mosquitoes, in particular aedes sticticus and aedes vexans, causes substantial nuisance and reduces life quality for inhabitants of infested areas and can have a negative impact on the socio-economic conditions of a region. we compared the previous, present, and predicted geographic distribution of ae. sticticus in sweden. previous records from the literature until 1990 list the species in three out of 21 swedish counties. beginning in 1998, studies show that the ...200920836814
high species richness of chironomidae (diptera) in temporary flooded wetlands associated with high species turn-over rates.species richness and species turn-over of chironomidae was studied in irregularly flooded wetlands of the river dalälven flood-plains in central sweden. the chironomid fauna, sampled with emergence traps in six wetlands over six summers, contained as much as 135 species, and the cumulative species curves indicated that the regional species pool contain several more species. recurrent irregular floods may have induced this high chironomid species richness and the high species turn-over in the tem ...201019939319
influence of molting on efficacy of two functionally different larvicides: bti and temephos.the sensitivity of the second, third (l3), and fourth (l4) instars of culex pipiens l. and ochlerotatus sticticus (meigen) to two larvicides, temephos and bacillus thuringiensis variety israelensis (bti) was tested with and without molting occurring in the experiments. in the first experiment for both tested mosquito species, lc50 values increased from the second to the fourth instar when tested against temephos, whereas for bti the opposite trend was observed. the highest lc50 value was found f ...200818767729
field evaluation against mosquitoes of regular and polymer-based deet formulations in manitoba, canada, with comment on methodological issues.studies were carried out in manitoba, canada, to evaluate the efficacy of three repellent products for protection of human subjects against mosquito bites. all test substances contained the active ingredient n,n-diethyl-3-methylbenzamide (deet); two were polymer-based creams (3m ultrathon insect repellent and morflex deet insect repellent 30) and the third (muskol insect repellent) was an alcohol-based pump spray formulation. application of repellent was to the forearm and lower legs of subjects ...200717547231
an assessment of the effectiveness of the mosquito magnet pro model for suppression of nuisance mosquitoes.we tested the effectiveness of the american biophysics corporation mosquito magnet pro model (abc-pro) to reduce mosquito abundance in an urban (wolseley) and in a rural (fort whyte) setting in winnipeg, manitoba in 2001 and 2002. assessment was based on comparisons with control sites by using centers for disease control (cdc) light traps and landing counts on human observers. over a period of 94 trap nights, the abc-pro collected more than an estimated 2,000,000 mosquitoes of 6 species. aedes v ...200617067037
field isolations of dirofilaria from mosquitoes in alabama.field collections of mosquitoes were made april-september 1977 and 1978 in the immediate vicinity of a hunting-dog kennel where the dogs had a chronic history of heartworm infection. among 19 mosquito species taken in light-trap collections, only aedes sticticus, ae. vexans, and anopheles punctipennis were found infected with what were presumed to be d. immitis larvae. based on natural infection rates and the relative abundance of these three host species, an. punctipennis and ae. sticticus appe ...19807365629
two more mosquito species proved as vectors of tahyna virus in czechoslovakia.two strains of tahyna virus were isolated during mosquito virological testing in summer 1975 in the littoral zone of large fishponds in south moravia. the first of them was isolated from culex modestus mosquito, the other one from aedes sticticus. virus isolation from these species proved them to be vectors of tahyna virus, as it was found already experimentally that tahyăn virus multiplies in these mosquitoes. this virus was isolated from the two species for the first time in central europe and ...1977881145
[economic significance of the prevention of losses caused by blood-sucking diptera in grazing dairy cows].it was was demonstrated in an experiment that the blood-sucking dipterous insects adversely affected the efficiency of cows on pasture; these cows showed a significantly decreased milk yield and milk fat percentage. the experiment was conducted in south bohemia at chlum u trebonĕ where seven species of gnats occurred in considerable abundancy, including the largest populations of aedes sticticus (meig.), ae. cinereus meig., ae. vexans meig. and ae. punctor kirby, which represented more than 80% ...1979111393
california encephalitis group viruses isolated from mosquitoes collected in southern and arctic norway.three virus strains serologically related to the california encephalitis group (bunyaviridae) of arboviruses were isolated from 7331 mosquitoes collected in norway in june-august 1975. two of the isolates (s 548 and s 618) seemed to be closely related and the third, s 568, more distantly related by serological techniques to tahyna virus. viruses were found in the mosquito species aedes sticticus, a. diantaeus and a. hexodontus colllected (in order) from oyern (59 degrees n, 11 degrees 12' e), tr ...197831761
which mosquitoes (diptera: culicidae) are candidates for dna extraction in forensic practice?mosquitoes can be of importance in forensic context as a source of the perpretator's dna. the aim of this study was to find how can we optimize the selection of appropriate mosquito individuals. the study was based on the data of 177833 trapped female mosquitoes and 105236 individuals which were collected directly from human skin. the mean human-specific biting willingness value of aedes species was the highest (mean: 0.8). significant differences were found between the human-specific biting wil ...201830005339
pest occurrence of aedes rossicus close to the arctic circle in northern sweden.major nuisance species are found among the floodwater mosquitoes and snow-pool mosquitoes, with the former being the main reason for mosquito control in most areas. nuisance species vary with the area, and previous reports from northern areas conclude that the nuisance is most often caused by snow-pool mosquitoes. we investigated the mosquito fauna and abundances of host-seeking females using cdc traps baited with carbon dioxide, in övertorneå city near the arctic circle in northern sweden, afte ...201829757502
