laboratory transmission of japanese encephalitis, west nile, and getah viruses by mosquitoes (diptera: culicidae) collected near camp greaves, gyeonggi province, republic of korea 2003.we conducted experimental studies to evaluate mosquitoes captured in paju county, gyeonggi province, republic of korea, for their ability to transmit west nile virus (family flaviviridae, genus flavivirus, wnv), japanese encephalitis virus (family flaviviridae, genus flavivirus, jev), and getah virus (family togaviridae, genus alphavirus, getv) under laboratory conditions. both culex pipiens pallens coquillett and culex tritaeniorhynchus giles were highly susceptible to infection with wnv, with ...200617017248
insecticide resistance in potential vector mosquitoes for west nile virus in japan.culex pipiens complex is the significant vector mosquito of west nile virus. to take stock of the current situation of insecticide susceptibilities and design an ideal mosquito control strategy, we collected culex pipiens pallens coquillet, culex pipiens form molestus forskal, and culex quinquefasciatus say from fields in japan and conducted bioassays for five larvicides (fenitrothion, temephos, etofenprox, diflubenzuron, and pyriproxyfen) by using a larval dipping method. among five insecticide ...200717915515
host-feeding habits of culex pipiens and aedes albopictus (diptera: culicidae) collected at the urban and suburban residential areas of japan.to evaluate the vectorial capacity of mosquitoes for viruses in japan, the host-feeding habits of the mosquitoes were analyzed by sequencing polymerase chain reaction-amplified fragments of the cytochrome b and 16s ribosomal rna regions of the mitochondrial dna of 516 mosquitoes of 15 species from seven genera that were collected from residential areas during 2003-2006. culex pipiens l. and aedes albopictus skuse were the most commonly collected species in urban and suburban residential areas. a ...201020496592
experimental studies on comparison of the potential vector competence of four species of culex mosquitoes in china to transmit west nile virus.to assess the risk that indigenous mosquitoes in china are capable of transmitting and sustaining west nile virus (wnv), four important culex mosquito species, culex tritaeniorhynchus, culex modestus, culex pipiens pallens, and culex pipiens quinquefasciatus, were allowed to feed on the artificial infectious blood meal with wnv dose of 10(6.8) plaque-forming unit/ml and tested approximately 2 wk later to determine infection and transmission rates. the results indicated that four culex mosquitoes ...201020939372
larvicidal activity and possible mode of action of four flavonoids and two fatty acids identified in millettia pinnata seed toward three mosquito species.aedes aegypti and aedes albopictus and culex pipiens pallens mosquitoes transmit dengue fever and west nile virus diseases, respectively. this study was conducted to determine the toxicity and mechanism of action of four flavonoids and two fatty acids from millettia pinnata (fabaceae) seed as well as six pure fatty acids and four fatty acid esters toward third instar larvae from insecticide-susceptible c. pipiens pallens and a. aegypti as well as wild a. albopictus. efficacy of 12 experimental l ...201525928224
identification of qtls conferring resistance to deltamethrin in culex pipiens pallens.culex pipiens pallens is the most abundant culex mosquito species in northern china and is an important vector of bancroftian filariasis and west nile virus. deltamethrin is an insecticide that is widely used for mosquito control, however resistance to this and other insecticides has become a major challenge in the control of vector-borne diseases that appear to be inherited quantitatively. furthermore, the genetic basis of insecticide resistance remains poorly understood. in this study, quantit ...201526484540
larvicidal activity of magnolia denudata seed hydrodistillate constituents and related compounds and liquid formulations towards two susceptible and two wild mosquito species.anopheles sinensis, aedes aegypti and aedes albopictus and culex pipiens pallens mosquitoes transmit malaria, dengue fever and west nile virus diseases respectively. this study was conducted to determine the toxicity of 17 constituents from magnolia denudata seed hydrodistillate (md-shd) and four experimental md-shd liquid formulations (10-50 mg l(-1) liquid) to third-instar larvae from insecticide-susceptible cx. p. pallens and ae. aegypti as well as wild ae. albopictus and an. sinensis.201626085316
larvicidal activity of lignans and alkaloid identified in zanthoxylum piperitum bark toward insecticide-susceptible and wild culex pipiens pallens and aedes aegypti.the yellow fever mosquito, aedes aegypti, and the common house mosquito, culex pipiens pallens, transmit dengue fever and west nile virus diseases, respectively. this study was conducted to determine the toxicity of the three lignans (-)-asarinin, sesamin and (+)-xanthoxylol-γ,γ-dimethylallylether (xda), and the alkaloid pellitorine from zanthoxylum piperitum (rutaceae) bark to third-instar larvae from insecticide-susceptible c. pipiens pallens and ae. aegypti as well as wild c. pipiens pallens ...201728472971
infection and dissemination of west nile virus in china by the potential vector, culex pipiens pallens.the distribution of the west nile virus (wnv) in the organs and tissues of the mosquito culex pipiens pallens, a potential vector of wnv in china, was investigated up to 14 days after oral infection. the wnv antigen was detected in paraffin-embedded mosquitoes using immunocytochemistry and viral titers of post-infected mosquitoes determined by plaque assay. viral titers sharply decreased 24 h post-infection, were undetectable for the first few days, then rose over the course of infection. the fi ...201424820559
identification of genes involved in pyrethroid-, propoxur-, and dichlorvos- insecticides resistance in the mosquitoes, culex pipiens complex (diptera: culicidae).culex pipiens pallens and cx. p. quinquefasciatus are important vectors of many diseases, such as west nile fever and lymphatic filariasis. the widespread use of insecticides to control these disease vectors and other insect pests has led to insecticide resistance becoming common in these species. in this study, high throughout illumina sequencing was used to identify hundreds of cx. p. pallens and cx. p. quinquefasciatus genes that were differentially expressed in response to insecticide exposu ...201626802491
