alphavirus infection in mosquitoes at the ross river reservoir, north queensland, 1990-1993.this study addresses the potential problem of alphavirus infection associated with recreational use of the ross river reservoir in north queensland, australia. from 1990 to 1993, 51,497 adult female mosquitoes were collected mainly by co2-supplemented light traps. four localities within the reservoir were considered and compared with mosquitoes collected during 1991 from 2 public localities around townsville city. ten isolates of ross river virus, one of barmah forest virus, and 2 of sindbis vir ...19968887221
an overview of remote sensing and gis for surveillance of mosquito vector habitats and risk assessment.this paper provides a brief nontechnical overview of the use of remote sensing to achieve multiple objectives, focusing on mosquito management. it also shows how geographic information systems, combined with remote sensing analysis, have the potential to assist in minimizing disease risk. examples are used from subtropical queensland, australia, where the salt marsh mosquito, aedes vigilax, and the freshwater species, culex annulirostris, are vectors of human arbovirus diseases such as ross rive ...19989673930
vector competence of mosquitoes (diptera: culicidae) from maroochy shire, australia, for barmah forest virus.mosquitoes were collected in light traps from maroochy shire and fed on blood containing the sympatric bf1611 strain of barmah forest virus (bf). saltmarsh aedes vigilax (skuse) and freshwater aedes procax (skuse) were highly susceptible to infection, with id50s of 10(1.7) and 10(1.5) african green monkey kidney (vero) cell culture infectious dose, 50% endpoint (ccid50) per mosquito, respectively, followed by aedes multiplex (theobald) and aedes funereus (theobald) with 10(2.5) and 10(3.2) ccid5 ...199910593091
vector competence of aedes aegypti, culex sitiens, culex annulirostris, and culex quinquefasciatus (diptera: culicidae) for barmah forest virus.aedes aegypti (l.), culex sitiens weidemann, culex annulirostris skuse, and culex quinquefasciatus say mosquitoes colonized at the queensland institute of medical research, brisbane australia, were fed on blood containing barmah forest virus (bf). only cx. annulirostris was susceptible to infection, with a median cell culture infectious dose (ccid50) of 10(3.36) per mosquito. ae. aegypti and cx. quinquefasciatus were infected experimentally, but at rates of < 9%. cx. sitiens did not become infec ...200011004776
occurrence of ross river virus and barmah forest virus in mosquitoes at shoalwater bay military training area, queensland, australia.shoalwater bay military training area (swbta), 2,713 km2 of land located 50-80 km north of rockhampton, queensland, australia, is used by australian and allied forces for training purposes. between march 1998 and february 2000, monthly collections of mosquitoes at 15 sites were conducted using carbon dioxide-baited traps to study the seasonal occurrence of mosquitoes and ross river virus (rrv) and barmah forest virus (bfv) in mosquitoes. a total of 72,616 mosquitoes, comprising 3,897 pools were ...200414989354
definition of ross river virus vectors at maroochy shire, australia.evidence of ross river (rr) virus infection in field-collected mosquitoes and data from laboratory vector competence experiments incriminated a range of mosquito species as important vectors of rr virus in maroochy shire, queensland, australia. nine rr and 2 barmah forest virus isolates were recovered from 27,529 mosquitoes collected in light traps from maroochy shire during 1996. nine of the 10 most abundant mosquito species collected in light traps were fed on blood containing the b94/20 strai ...200015218919
mosquito feeding patterns and natural infection of vertebrates with ross river and barmah forest viruses in brisbane, australia.host feeding patterns of mosquitoes were assessed through the identification of 865 blood meals collected from brisbane during 2000-2001. under natural conditions, mosquito feeding (including that of culex annulirostris, aedes vigilax, and aedes notoscriptus) was primarily on dogs (37.4%), but also on birds (18.4%), horses (16.8%), brushtail possums (13.3%), humans (11.6%), and cats, flying foxes, and macropods, depending on site. from 1997 to 1999, sera (n=1706) were collected from dogs, cats, ...200717360861
discovery of cocirculating ross river virus and barmah forest virus at wide bay military training area, northeastern australia.an arbovirus surveillance military exercise was conducted to assess the risk of ross river virus (rrv) and barmah forest virus (bfv) in the australian defence force (adf) wide bay training area (wbta), northeastern australia, in april 2018. of the 5,540 female mosquitoes collected, 3,702 were screened for rrv and bfv by quantitative reverse transcription-polymerase chain reaction in a field laboratory. one pool of verrallina funerea was positive for rrv and 8 pools (7 pools of aedes vigilax and ...201931647704
integrating statistical and mechanistic approaches with biotic and environmental variables improves model predictions of the impact of climate and land-use changes on future mosquito-vector abundance, diversity and distributions in australia.changes to australia's climate and land-use patterns could result in expanded spatial and temporal distributions of endemic mosquito vectors including aedes and culex species that transmit medically important arboviruses. climate and land-use changes greatly influence the suitability of habitats for mosquitoes and their behaviors such as mating, feeding and oviposition. changes in these behaviors in turn determine future species-specific mosquito diversity, distribution and abundance. in this re ...202032967711
