ecology of invasive mosquitoes: effects on resident species and on human health.investigations of biological invasions focus on patterns and processes that are related to introduction, establishment, spread and impacts of introduced species. this review focuses on the ecological interactions operating during invasions by the most prominent group of insect vectors of disease, mosquitoes. first, we review characteristics of non-native mosquito species that have established viable populations, and those invasive species that have spread widely and had major impacts, testing wh ...200517637849
biting cycles of some potential vector mosquitos of japanese encephalitis of assam, india.biting activities of five potential vector species of japanese encephalitis (je) were observed in a je affected district of assam, india. most of the species exhibited two peak periods of biting activity, one in early hours and other around midnight. however, in case of culex fuscocephala several peaks were observed throughout the night.19958525408
population dynamics of anthropophilic mosquitoes during the northeast monsoon season in the malaria epidemic zone of sri lanka.mosquito-borne diseases are a major health problem in sri lanka. human biting mosquitoes were collected during the night (18.00-06.00 hours) at nikawehera village, in the malaria endemic intermediate rainfall zone of the country. collections were made at monthly intervals in the period october 1991 to april 1992, which included the main rainy season due to the northeast monsoon (october-january). thirteen anopheles, eleven culex, three aedes, three mansonia and one armigeres species were identif ...19947949318

comparisons of rice field mosquito (diptera: culicidae) abundance among areas with different agricultural practices in northern mosquitoes were collected from 3 areas in northern thailand with different availabilities of rice fields for larval habitats by using blacklight, truck, and pig-baited traps. culex tritaeniorhynchus giles and culex gelidus theobald were dominant in all samples. significant study-area differences were found in light and truck trap collections for cx. tritaeniorhynchus and cx. gelidus, but not for culex vishnui theobald + culex pseudovishnui colless. in pig-baited sample area differences wer ...19989775619
spatio-temporal distribution of dengue and lymphatic filariasis vectors along an altitudinal transect in central nepal.rapidly increasing temperatures in the mountain region of nepal and recent reports of dengue fever and lymphatic filariasis cases from mountainous areas of central nepal prompted us to study the spatio-temporal distribution of the vectors of these two diseases along an altitudinal transect in central nepal.201425078276
the resting sites and blood-meal sources of anopheles minimus in taiwan.the who declared taiwan free from malaria in 1965, but in 2003 the reporting of two introduced cases in a rural area suggested a possible local transmission of this disease. therefore, understanding the resting sites and the blood sources of anopheles minimus is crucial in order to provide information for implementing vector control strategies.200818538036

host preference of mosquito vectors of japanese encephalitis.the host preference of 4 culex mosquito species collected in miaoli and pingtung counties, taiwan was studied by capillary precipitin method. antisera to alum-precipitated sera of man, bovine, swine, rabbit, horse, dog, cat, mouse, chicken, duck, and pigeon were produced in rabbits and reacted with 758 mosquito blood meals among which reactions to one or more antisera. culex annulus and culex tritaeniorhynchus summorosus showed a great avidity for pig, and culex fuscocephala for bovine. culex pi ...1975181218
newly recognized mosquito-associated viruses in mainland china, in the last two decades.there are four principal arboviruses in mainland china. two kinds of them are mosquito-borne viruses, namely japanese encephalitis virus and dengue virus, which lead to japanese encephalitis, and dengue fever/dengue hemorrhagic fever respectively; the other two are tick-borne viruses, namely tick-borne encephalitis virus and crimean-congo hemorrhagic fever virus (also known as xinjiang hemorrhagic fever virus), which contribute to tick-borne encephalitis and xinjiang hemorrhagic fever respective ...201121314994
species composition and population dynamics of malaria vectors in three previously ignored aquatic systems in sri 2015 alone there were an estimated 214 million new cases of malaria across the globe and 438,000 deaths were reported. although indigenous malaria has not been reported in sri lanka since 2012, to date 247 imported cases of malaria have been identified. knowledge of the locations, behaviour and vectorial capacity of potential malarial vectors is therefore needed to prevent future outbreaks. attention is now being focused on some previously ignored habitats.201627165184
mosquito vector diversity across habitats in central thailand endemic for dengue and other arthropod-borne diseases.recent years have seen the greatest ecological disturbances of our times, with global human expansion, species and habitat loss, climate change, and the emergence of new and previously-known infectious diseases. biodiversity loss affects infectious disease risk by disrupting normal relationships between hosts and pathogens. mosquito-borne pathogens respond to changing dynamics on multiple transmission levels and appear to increase in disturbed systems, yet current knowledge of mosquito diversity ...201324205420
risky behaviors: effects of toxorhynchites splendens (diptera: culicidae) predator on the behavior of three mosquito species.viable biocontrol agents for mosquito control are quite rare, therefore improving the efficacy of existing biological agents is an important study. we need to have a better understanding of the predation-risk behavioral responses toward prey. this research examined prey choices by toxorhynchites splendens by monitoring the behavioral responses of aedes aegypti, aedes albopictus, and anopheles sinensis larvae when exposed to the predator. the results show that tx. splendens prefers to consume ae. ...201526386041

regulation of cell survival and death during flavivirus infections.flaviviruses, ss(+) rna viruses, include many of mankind's most important pathogens. their pathogenicity derives from their ability to infect many types of cells including neurons, to replicate, and eventually to kill the cells. flaviviruses can activate tumor necrosis factor α and both intrinsic (bax-mediated) and extrinsic pathways to apoptosis. thus they can use many approaches for activating these pathways. infection can lead to necrosis if viral load is extremely high or to other types of c ...024921001
detection of west nile virus in six mosquito species in synchrony with seroconversion among sentinel chickens in india.west nile virus (wnv) is a zoonotic flavivirus maintained in mosquito-bird transmission cycle. although humans are accidental hosts, fatal outcomes following wnv infection have been reported from india. studies have identified wnv as an important etiological agent causing acute encephalitis syndrome in assam, northeast india. while circulation of wnv is evident, the role of vectors and avian hosts involved in the transmission remains unclear. in this study we identified local mosquito species fo ...201728061903
field observation on the efficacy of toxorhynchites splendens (wiedemann) as a biocontrol agent against aedes albopictus (skuse) larvae in a cemetery.this study explored the efficacy of toxorhynchites splendens, predator of aedes albopictus as a biocontrol agent. there was a negative correlation between ae. albopictus larval population and tx. splendens larval population in ovitraps (r=-0.287, r²=0.0821). the correlation is higher between the mean number of ae. albopictus larvae per ovitrap and the number of tx. splendens larvae in an ovitrap (r=-0.987, r²=0.9737). larvae of tx. splendens were observed to co-exist with larvae of ae. albopictu ...201122041750
