| response of iowa mosquito populations to unusual precipitation patterns as measured by new jersey light trap collections. | new jersey light trap data from 1993, a year with unusually high amounts of precipitation, and 1994 were compared with mean light trap counts for the previous 8-10 years in each of 6 locations. the study took place in iowa. in 1993, aedes trivittatus and culex tarsalis populations were unchanged. anopheles punctipennis and culex pipiens complex populations were significantly higher, and aedes vexans populations increased in all 6 sites, significantly so in 2 sites. species composition was unchan ... | 1995 | 7595446 |
| genomic sequence and phylogenetic analysis of culex flavivirus, an insect-specific flavivirus, isolated from culex pipiens (diptera: culicidae) in iowa. | adult mosquitoes (diptera: culicidae) were collected in 2007 and tested for specific viruses, including west nile virus, as part of the ongoing arbovirus surveillance efforts in the state of iowa. a subset of these mosquitoes (6,061 individuals in 340 pools) was further tested by reverse transcription-polymerase chain reaction (rt-pcr) using flavivirus universal primers. of the 211 pools of culex pipiens (l.) tested, 50 were positive. one of 51 pools of culex tarsalis coquillet was also positive ... | 2009 | 19645300 |
| evidence of efficient transovarial transmission of culex flavivirus by culex pipiens (diptera: culicidae). | this study determined the transovarial transmission (tot) potential and tissue tropisms of culex flavivirus (cxfv), an insect-specific flavivirus, in culex pipiens (l.). several hundred mosquito egg rafts were collected in the field, transferred to the insectaries, reared to the fourth larval instar, and identified using morphological characteristics. cx. pipiens were reared to adults, allowed to oviposit in individual containers, and tested for cxfv rna by reverse transcription-polymerase chain ... | 2011 | 21936322 |
| the abundance and seasonal distribution of culex mosquitoes in iowa during 1995-97. | the abundance and seasonal distribution of culex mosquitoes were monitored by measuring oviposition activity during the summers of 1995, 1996, and 1997. five species of culicine mosquitoes laid egg rafts in ovitraps. egg rafts of 4 culex species-cx. restuans (54.98%), cx. pipiens (25.41%), cx. salinarius (12.18%), and cx. tarsalis (0.14%)-constituted more than 92% of the total egg rafts collected. culiseta inornata (0.1%) was the only other species to lay viable egg rafts in the ovitraps. a smal ... | 2000 | 11198913 |
| efficacy of bacillus sphaericus and bacillus thuringiensis var. israelensis for control of culex pipiens and floodwater aedes larvae in iowa. | granular and flowable concentrate formulations of bacillus thuringiensis var. israelensis provided a 90-100% reduction in aedes vexans and culex spp. larvae in natural larval habitats. a briquet formulation of b. thuringiensis was less effective, providing a 12-76% reduction. no residual activity occurred in sites treated with b. thuringiensis. granular formulations of bacillus sphaericus (2.78-8.42 kg/ha) caused a 100% reduction in culex pipiens larvae in natural sites and artificial pools. bac ... | 1987 | 3504943 |
| ecological niche modeling of potential west nile virus vector mosquito species in iowa. | ecological niche modeling (enm) algorithms, maximum entropy species distribution modeling (maxent) and genetic algorithm for rule-set prediction (garp), were used to develop models in iowa for three species of mosquito - two significant, extant west nile virus (wnv) vectors (culex pipiens l and culex tarsalis coquillett (diptera: culicidae)), and the nuisance mosquito, aedes vexans meigen (diptera: culicidae), a potential wnv bridge vector. occurrence data for the three mosquito species from a s ... | 2010 | 20874412 |
| spatiotemporal investigation of adult mosquito (diptera: culicidae) populations in an eastern iowa county, usa. | landscape and climatic factors regulate distributions of mosquitoes (diptera: culicidae) over time and space. the anthropogenic control of mosquito populations is often carried out at a local administrative scale, and it is applied based on the relevant agency's experiential knowledge rather than systematic analysis of spatial and temporal data. to address this shortcoming, a spatial and temporal analysis of landscape and climatic parameters in relation to mosquito populations in black hawk coun ... | 2007 | 18047216 |
| vertebrate host specificity and experimental vectors of plasmodium (novyella) kempi sp. n. from the eastern wild turkey in iowa. | vertebrate host specificity, experimental laboratory vectors, and a description of plasmodium (novyella) kempi sp. n. from eastern wild turkeys (meleagris gallopavo silvestris vieillot) in iowa are presented. plasmodium kempi is infective for domestic turkeys, bobwhites (colinus virginianus), chukars (alectoris graeca), guinea fowl (numida meleagris), peacocks (pavo cristatus), and canaries (serinus canaria), produces a transient infection in mallards (anas platyrhynchos) and domestic geese (ans ... | 1983 | 6644918 |
