| using a dynamic hydrology model to predict mosquito abundances in flood and swamp water. | we modeled surface wetness at high resolution, using a dynamic hydrology model, to predict flood and swamp water mosquito abundances. historical meteorologic data, as well as topographic, soil, and vegetation data, were used to model surface wetness and identify potential fresh and swamp water breeding habitats in two northern new jersey watersheds. surface wetness was positively associated with the subsequent abundance of the dominant floodwater mosquito species, aedes vexans, and the swamp wat ... | 2002 | 11749741 |
| reassessment of the role and utility of wind in suppression of mosquito (diptera: culicidae) host finding: stimulus dilution supported over flight limitation. | in a central michigan wetland setting, with abundant aedes vexans (meigen), anopheles walkeri (theobald), and coquillettidea perturbans (walker), electric fan-generated wind strongly reduced mosquito catches in centers for disease control and prevention light traps releasing carbon dioxide at 650 or 1,950 ml/min. this relationship was negatively logarithmic over the range of velocities tested (0 m/s to 3.7 m/s; 0-8.3 mph) and closely matched the theoretical dilution function predicted to occur w ... | 2003 | 14596273 |
| mosquito and arbovirus activity during 1997-2002 in a wetland in northeastern mississippi. | the species composition and population dynamics of adult mosquitoes in a wetland near iuka, ms, were analyzed over a 6-yr period (1997-2002) and reverse transcription-polymerase chain reaction (pcr) detection rates of arboviruses determined during five of those years. blood meals of three likely vector species were identified using a pcr-based method that allows identification of the host to species. culex erraticus (dyar & knab) composed 51.9% of the population during the 6-yr period with 295 f ... | 2004 | 15185956 |
| epidemiology of west nile virus in connecticut: a five-year analysis of mosquito data 1999-2003. | two hundred and ten isolations of west nile virus (wnv) were obtained from 17 mosquito species in six genera in statewide surveillance conducted in connecticut from june through october, 1999-2003. culex pipiens (86), culex salinarius (32), culex restuans (26), culiseta melanura (32), and aedes vexans (12) were implicated as the most likely vectors of wnv in the region based on virus isolation data. culex pipiens was abundant from july through september and is likely involved in early season enz ... | 2004 | 15682518 |
| mosquito surveillance for west nile virus in southeastern wisconsin--2002. | in 2001, west nile virus (wnv) was identified among dead american crows and bluejays in five counties in southeastern wisconsin. in response to the introduction of wnv, a pilot mosquito surveillance program was initiated in these five southeastern wisconsin counties during the summer of 2002. forty sites were selected for surveillance one night each week during a 17-week period. mosquitoes were collected in carbon dioxide-baited light traps and gravid traps. during the study period 31,419 mosqui ... | 2003 | 15931283 |
| isolations of jamestown canyon virus (bunyaviridae: orthobunyavirus) from field-collected mosquitoes (diptera: culicidae) in connecticut, usa: a ten-year analysis, 1997-2006. | jamestown canyon virus (jcv) (bunyaviridae: orthobunyavirus) is a mosquito-borne zoonosis belonging to the california serogroup. it has a wide geographic distribution, occurring throughout much of temperate north america. white-tailed deer, odocoileus virginianus are the principal amplification hosts, and boreal aedes and ochlerotatus mosquitoes are the primary vectors. a 10-year study was undertaken to identify potential mosquito vectors in connecticut, quantify seasonal prevalence rates of inf ... | 2008 | 18386967 |

| climate change impacts on west nile virus transmission in a global context. | west nile virus (wnv), the most widely distributed virus of the encephalitic flaviviruses, is a vector-borne pathogen of global importance. the transmission cycle exists in rural and urban areas where the virus infects birds, humans, horses and other mammals. multiple factors impact the transmission and distribution of wnv, related to the dynamics and interactions between pathogen, vector, vertebrate hosts and environment. hence, among other drivers, weather conditions have direct and indirect i ... | 0 | 25688020 |
| a regional model for malaria vector developmental habitats evaluated using explicit, pond-resolving surface hydrology simulations. | dynamical malaria models can relate precipitation to the availability of vector breeding sites using simple models of surface hydrology. here, a revised scheme is developed for the vectri malaria model, which is evaluated alongside the default scheme using a two year simulation by hydremats, a 10 metre resolution, village-scale model that explicitly simulates individual ponds. despite the simplicity of the two vectri surface hydrology parametrization schemes, they can reproduce the sub-seasonal ... | 2016 | 27003834 |
| geospatial analysis and seasonal distribution of west nile virus vectors (diptera: culicidae) in southern ontario, canada. | the purpose of this study was to establish geospatial and seasonal distributions of west nile virus vectors in southern ontario, canada using historical surveillance data from 2002 to 2014. we set out to produce mosquito abundance prediction surfaces for each of ontario's thirteen west nile virus vectors. we also set out to determine whether elevation and proximity to conservation areas and provincial parks, wetlands, and population centres could be used to improve our model. our results indicat ... | 2018 | 29597256 |
| effects of release rates on the range of attraction of carbon dioxide to some southwestern ontario mosquito species. | the effects of release rates of 0, 250, 500, 1,000 and 4,000 ml/min on the range of attraction of carbon dioxide to some southwestern ontario mosquito species was determined using ramp traps placed at 3, 7, 11, 15 and 19 m from a central pressurized cylinder. for female aedes vexans, spring aedes spp. and anopheles walkeri, an increase in the release rate of co2 from 1,000 to 4,000 ml/min resulted in extension of the range of attractiveness from between 3-7 m to between 7-11 m; rates of 500 and ... | 1989 | 2565369 |
| a taxonomic checklist of the mosquitoes of montana with notes on new geographic distributions. | an updated checklist of 50 species of mosquitoes found in montana is presented and includes 2 new records (aedes niphadopsis and anopheles walkeri) that can be added to the 2005 state list by darsie and ward. the results of a statewide mosquito surveillance program, conducted annually from 2004 to 2015, facilitated the establishment of an abundance rating of the species in the state and expanded the known geographic range for coquillettidia perturbans, ae. nigromaculis, and culiseta minnesotae. | 2016 | 28206866 |
| evidence of seasonal eggs in anopheles punctipennis (diptera: culicidae). | anopheles punctipennis (say), collected in october from resting sites in illinois, deposited two morphologically distinct types of egg batches. one type was similar to the seasonal "winter" egg of anopheles walkeri theobald, with an extensive exochorion that covered all except the tip of the egg. laboratory rearing of isofemale lines, under two different light-dark and temperature cycles, demonstrated that both types of eggs were intraspecific variants. f1 females from all "winter" egg batches d ... | 1992 | 1495082 |

| phylogeny of nearctic members of the anopheles maculipennis species group derived from the d2 variable region of 28s ribosomal rna. | phylogenetic affinities among taxa associated with the nearctic component of the anopheles maculipennis species group (subgenus anopheles) were inferred from sequence divergence in the d2 variable region of 28s ribosomal rna. the base composition of this region had a marked gc bias which ranged from 59.9% in anopheles walkeri to 65.1% in anopheles punctipennis e. although over two-thirds of the base positions in the d2 region were double-stranded (stem), substitution frequencies at single-strand ... | 1996 | 8899722 |
