| japanese encephalitis in sri lanka--the study of an epidemic: vector incrimination, porcine infection and human disease. | a prospective study of mosquito vectors, porcine infection and human disease was carried out during a japanese encephalitis (je) epidemic in the north central province of sri lanka (november-december 1987) and a subsequent non-epidemic year (1988). the epidemic involved 361 cases of human encephalitis, virologically confirmed by immunoglobulin m enzyme-linked immunosorbent assay (elisa), and was preceded 2-3 weeks earlier by sentinel porcine seroconversion. virus isolation and viral antigen dete ... | 1992 | 1329275 |
| survey of adult mosquitoes (diptera: culicidae) during irrigation development in the mahaweli project, sri lanka. | a survey of adult mosquitoes was done during 1986-1987 in an area undergoing irrigation development in the mahaweli project of sri lanka. the study encompassed two 12-mo phases of settlement and irrigation, respectively. diurnal human bait catches yielded 1,427 female mosquitoes in 27 species. nocturnal collections (human bait, cdc light traps, indoor resting catches) produced a total of 30,491 females in 67 species. comparisons with an earlier survey in the predevelopment forest showed that the ... | 1991 | 1678784 |
| [the natural infection rate of mosquitoes by japanese encephalitis b virus in yunnan province]. | in july-september 1983-1987, 57,898 adult female mosquitoes belonging to 29 species of 8 genera were collected from japanese b encephalitis (je) epidemic areas in yunnan, china, and were examined by c 6/36 cell method and sucking mouse method. twenty-eight strains of je virus were isolated from culex tritaeniorhychus, c. whitomorei, c. pseudovishnui, c. fuscocephala, c. annulus, c. gelidus, anopheles sinensis, mansonia uniformis, aedes albopictus, ae. vexans, ae. lineatopennis, and ae. assamensi ... | 1990 | 1979768 |
| viruses isolated from mosquitoes collected in sri lanka. | attempts to isolate viruses from 178,181 unengorged female mosquitoes collected from different ecologic areas of sri lanka yielded 31 isolates: 17 of japanese encephalitis (je) virus, nine of getah virus, three of a batai-related bunyavirus, and two of arkonam virus. culex tritaeniorhynchus and mansonia uniformis mosquitoes were found to carry je virus in a dry zone nonepidemic area, and cx. pseudovishnui was found to carry it in a wet zone nonepidemic area. japanese encephalitis virus was isola ... | 1994 | 7915499 |
| studies on japanese encephalitis vector mosquitoes in selangor, malaysia. | mosquito collections were carried out from may to june 1992 and from september to december 1992 in an area where a case of japanese encephalitis was confirmed. a total of 40,072 mosquitoes belonging to 35 species and 8 genera were collected. the dominant species in that locality were culex vishnui, culex tritaeniorhynchus, culex pseudovishnui, culex gelidus, aedes butleri, and mansonia uniformis. | 1993 | 8126485 |
| virus isolation from wild-caught mosquitoes during a japanese encephalitis outbreak in kerala in 1996. | out of 5357 wild-caught mosquitoes in 163 pools tested for virus using antigen capture elisa and an insect-bioassay (inoculation into toxorhynchites splendens larvae and identification by ifa using je virus-specific monoclonal antibody), 16 flavivirus isolations were made of which 12 (75%) were identified as je virus. of the 12 je virus isolations, 7 were from culex tritaeniorhynchus, 3 from mansonia uniformis and 1 each from ma. indiana and anopheles subpictus. four isolations from mansonia spe ... | 1997 | 9248207 |
| a long-term study on vector abundance & seasonal prevalence in relation to the occurrence of japanese encephalitis in gorakhpur district, uttar pradesh. | japanese encephalitis (je) virus is an important cause of viral encephalitis in gorakhpur district, up. the area has been experiencing outbreaks of je since 1978. no in-depth longitudinal studies have been carried out on the mosquito species, particularly je vectors prevailing in the area. entomological studies were carried out in the district in order to determine the species composition, relative abundance and seasonal prevalence of mosquitoes in relation to the incidence of je. | 2003 | 14575175 |
| a recent survey of mosquito fauna in guangdong province,southern china, with a review of past records [corrected]. | the southern province of guangdong has long been subject to endemic mosquito-borne diseases. in recent years, this region of china has experienced rapid, extensive economic development involving environmental change, making much of the scant knowledge of its mosquito fauna obsolete. this paper reviews previous mosquito surveys, some of which may be too old to be of relevance to present-day conditions, and presents the results of a recent survey of adult and immature mosquitoes. the main vectors ... | 2008 | 19120964 |
| comparison of the efficacy of co(2) -baited and unbaited light traps, gravid traps, backpack aspirators, and sweep net collections for sampling mosquitoes infected with japanese encephalitis virus. | two field studies were conducted to determine the efficacy of mosquito collection methods for species composition, species abundance, and japanese encephalitis virus infection rates in taiwan. traps evaluated included john w. hock (jh) model ud black light traps, jh model 1012 new standard miniature cdc light traps, jh model 1712 cdc gravid traps, and taiwan-made pest-o-lite light traps. backpack aspirators and sweep nets were also used to collect the resting population. culex tritaeniorhynchus ... | 2011 | 21635643 |
| mosquito biting activity on humans & detection of plasmodium falciparum infection in anopheles stephensi in goa, india. | knowledge of the bionomics of mosquitoes, especially of disease vectors, is essential to plan appropriate vector avoidance and control strategies. information on biting activity of vectors during the night hours in different seasons is important for choosing personal protection measures. this study was carried out to find out the composition of mosquito fauna biting on humans and seasonal biting trends in goa, india. | 0 | 22382193 |
| distribution and phylogeny of wolbachia strains in wild mosquito populations in sri lanka. | wolbachia are a group of maternally inherited intracellular bacteria known to be widespread among arthropods. infections with wolbachia cause declines of host populations, and also induce host resistance to a wide range of pathogens. over the past few decades, researchers were curious to use wolbachia as a biological tool to control mosquito vectors. during the present study, assessment of the prevalence of wolbachia infections among wild mosquito populations in sri lanka where mosquito-borne di ... | 2017 | 28490339 |
