isolation of arboviruses from mosquitoes (diptera: culicidae) collected from the gulf plains region of northwest queensland, part of investigations into japanese encephalitis (je) virus and related flaviviruses in northern australia, 153,529 mosquitoes were collected and processed for virus isolation from the gulf plains region of northwest queensland. collections from within 30 km of each of the townships of croydon, normanton and karumba yielded 3,087 (2.0%), 66,009 (43.0%), and 84,433 (55.0%) mosquitoes, respectively, from which 16 viruses were isolated. four isolates of murray valley encephalitis (mve), two of ...200212349863
flavivirus isolations from mosquitoes collected from western cape york peninsula, australia, 1999-2000.after the 1st appearance of japanese encephalitis virus (je) on mainland australia in 1998, a study was undertaken to investigate whether je had become established in enzootic transmission cycles on western cape york peninsula. adult mosquitoes were collected during the late wet season from kowanyama and pormpuraaw in april 1999, and pormpuraaw and barr's yard in april 2000. despite processing 269,270 mosquitoes for virus isolation, no isolates of je were obtained. however, other flaviviruses co ...200314710742
rapid molecular detection methods for arboviruses of livestock of importance to northern europe.arthropod-borne viruses (arboviruses) have been responsible for some of the most explosive epidemics of emerging infectious diseases over the past decade. their impact on both human and livestock populations has been dramatic. the early detection either through surveillance or diagnosis of virus will be a critical feature in responding and resolving the emergence of such epidemics in the future. although some of the most important emerging arboviruses are human pathogens, this paper aims to high ...201222219660
mosquito communities and disease risk influenced by land use change and seasonality in the australian tropics.anthropogenic land use changes have contributed considerably to the rise of emerging and re-emerging mosquito-borne diseases. these diseases appear to be increasing as a result of the novel juxtapositions of habitats and species that can result in new interchanges of vectors, diseases and hosts. we studied whether the mosquito community structure varied between habitats and seasons and whether known disease vectors displayed habitat preferences in tropical australia.201627388293
development and field evaluation of the sentinel mosquito arbovirus capture kit (smack).although sentinel animals are used successfully throughout the world to monitor arbovirus activity, ethical considerations and cross-reactions in serological assays highlight the importance of developing viable alternatives. here we outline the development of a passive sentinel mosquito arbovirus capture kit (smack) that allows for the detection of arboviruses on honey-baited nucleic acid preservation cards (flinders technology associates; fta®) and has a similar trap efficacy as standard light ...201526444264
barrier screens: a method to sample blood-fed and host-seeking exophilic mosquitoes.determining the proportion of blood meals on humans by outdoor-feeding and resting mosquitoes is challenging. this is largely due to the difficulty of finding an adequate and unbiased sample of resting, engorged mosquitoes to enable the identification of host blood meal sources. this is particularly difficult in the south-west pacific countries of indonesia, the solomon islands and papua new guinea where thick vegetation constitutes the primary resting sites for the exophilic mosquitoes that are ...201323379959
entomological monitoring and evaluation: diverse transmission settings of icemr projects will require local and regional malaria elimination strategies.the unprecedented global efforts for malaria elimination in the past decade have resulted in altered vectorial systems, vector behaviors, and bionomics. these changes combined with increasingly evident heterogeneities in malaria transmission require innovative vector control strategies in addition to the established practices of long-lasting insecticidal nets and indoor residual spraying. integrated vector management will require focal and tailored vector control to achieve malaria elimination. ...201526259942
epidemiology and control of bovine ephemeral fever.bovine ephemeral fever (or 3-day sickness) is an acute febrile illness of cattle and water buffaloes. caused by an arthropod-borne rhabdovirus, bovine ephemeral fever virus (befv), the disease occurs seasonally over a vast expanse of the globe encompassing much of africa, the middle east, asia and australia. although mortality rates are typically low, infection prevalence and morbidity rates during outbreaks are often very high, causing serious economic impacts through loss of milk production, p ...201526511615
koolpinyah and yata viruses: two newly recognised ephemeroviruses from tropical regions of australia and africa.koolpinyah virus (koolv) isolated from healthy australian cattle and yata virus (yatv) isolated from a pool of mansonia uniformis mosquitoes in the central african republic have been tentatively identified as rhabdoviruses. koolv was shown previously to be related antigenically to kotonkon virus, an ephemerovirus that has caused an ephemeral fever-like illness in cattle in nigeria, but yatv failed to react antigenically with any other virus tested. here we report the complete genome sequences of ...201425457369
bovine ephemeral fever in iran: diagnosis, isolation and molecular characterization.bovine ephemeral fever (befv) is an arthropod-borne disease of cattle and water buffaloes. befv occurs seasonally in tropical, subtropical and temperate regions of africa, asia and australia. it has been known for the past decades in iran based on clinical signs but lack of an accurate diagnosis has made the real feature of disease obscured. this is the first scientific report on isolation and identification of the agent in which molecular diagnosis of befv was also set up with high sensitivity ...201526623431
plasticity of host selection by malaria vectors of papua new selection is an important determinant of vectorial capacity because malaria transmission increases when mosquitoes feed more on humans than non-humans. host selection also affects the outcome of long-lasting insecticidal nets (llin). despite the recent nationwide implementation of llin-based malaria control program in papua new guinea (png), little is known about the host selection of the local anopheles vectors. this study investigated the host selection of anopheles vectors in png.201728222769
field evaluation of repellent formulations containing deet and picaridin against mosquitoes in northern territory, australia.field efficacy of repellent formulations containing picaridin (1-methyl-propyl 2-(2-hydroxyethyl)-1-piperidinecarboxylate) or deet (n,n,-diethyl-3-methylbenzamide) against mosquitoes in northern territory, australia, was evaluated. the following repellent treatments were evaluated: 19.2% picaridin (autan repel army 20), a solution of 20% deet in ethanol, and 35% deet in a gel (australian defense force [adf]). the predominant mosquito species were culex annulirostris skuse (57.8%), anopheles mera ...200415185943
the effectiveness of light, 1-octen-3-ol, and carbon dioxide as attractants for anopheline mosquitoes in madang province, papua new guinea.the effectiveness of light, 1-octen-3-ol (octenol), carbon dioxide (co2) and a combination of co2 and octenol were compared as mosquito attractants using encephalitis vector surveillance traps in 2 villages in madang province, papua new guinea (png). five species were collected, anopheles koliensis, anopheles farauti 2, anopheles farauti 4, anopheles longirostris, and anopheles bancroftii. light alone was not attractive to any of these species, and the attractiveness of octenol alone, though gre ...200415532920
ribosomal dna spacer genotypes of the anopheles bancroftii group (diptera: culicidae) from australia and papua new guinea.mosquitoes of the anopheles bancroftii group collected from northern australia and papua new guinea (png) were investigated for sequence variation within the ribosomal dna its2. wing fringe morphology originally used to identify members of this group was compared to genotypes identified by restriction fragment length polymorphism analysis (rflp) and heteroduplex analysis (hda) of the rdna its2. members of this group separated into four rflp genotypes (a, b, c and d) with some genotypes displayin ...200111881804
