isolation of arboviruses from insects collected at beatrice hill, northern territory of australia, 1974-1976. | between october 1974 and may 1976, 57 596 mosquitoes, 169 957 culicoides, 5923 lasiohelea and 1043 phlebotomines were collected for virus isolation at beatrice hill (lat. 12 degrees 39's.,long. 131 degrees 20'e.) in the northern territory of australia. a total of 94 viruses belonging to 22 different serological groupings was isolated. the following species of insect yielded viruses which were identified and those viruses marked with an asterisk represent a new record of insect host: culex annuli ... | 1984 | 6152599 |
changes in mosquito populations with expansion of the ross river reservoir, australia, from stage 1 to stage 2a. | female mosquitoes were collected at 4 sites around the ross river reservoir (stage 2a) from 484 carbon dioxide-supplemented light traps. the seasonal abundance from these collections during 1991-93 was compared statistically with that for similar collections done for the stage 1 reservoir in 1984-85. principally due to clearing of the forest prior to the inundation of the stage 2a, several tree hole/plant axil and shaded pool species are no longer present or are rare. due to extensive loss of ma ... | 1995 | 7595448 |
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 ... | 1996 | 8887221 |
importance of hydrilla verticillata (hydrocharitaceae) as habitat for immature mosquitoes at the ross river reservoir, australia. | from november 1990 to november 1992, immature mosquitoes were sampled from the shoreline and from emergent beds of the submerged aquatic plant hydrilla verticillata at the ross river reservoir, northern australia. aerial mapping of hydrilla beds was done in conjunction with sampling to estimate total immature mosquito numbers. larvae of 7 species were found. culex annulirostris. anopheles annulipes s.l., and anopheles amictus comprised 80.4% of the total. peak larval densities occurred in the la ... | 1997 | 9249656 |
isolation of arboviruses from mosquitoes (diptera: culicidae) collected from the gulf plains region of northwest queensland, australia. | as 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 ... | 2002 | 12349863 |
infection of malaria (anopheles gambiae s.s.) and filariasis (culex quinquefasciatus) vectors with the entomopathogenic fungus metarhizium anisopliae. | current intra-domiciliary vector control depends on the application of residual insecticides and/or repellents. although biological control agents have been developed against aquatic mosquito stages, none are available for adults. following successful use of an entomopathogenic fungus against tsetse flies (diptera: glossinidae) we investigated the potency of this fungus as a biological control agent for adult malaria and filariasis vector mosquitoes. | 2003 | 14565851 |
entomopathogenic fungi for mosquito control: a review. | fungal diseases in insects are common and widespread and can decimate their populations in spectacular epizootics. virtually all insect orders are susceptible to fungal diseases, including dipterans. fungal pathogens such as lagenidium, coelomomyces and culicinomyces are known to affect mosquito populations, and have been studied extensively. there are, however, many other fungi that infect and kill mosquitoes at the larval and/or adult stage. the discovery, in 1977, of the selective mosquito-pa ... | 2004 | 15861235 |
enhanced arbovirus surveillance with deep sequencing: identification of novel rhabdoviruses and bunyaviruses in australian mosquitoes. | viral metagenomics characterizes known and identifies unknown viruses based on sequence similarities to any previously sequenced viral genomes. a metagenomics approach was used to identify virus sequences in australian mosquitoes causing cytopathic effects in inoculated mammalian cell cultures. sequence comparisons revealed strains of liao ning virus (reovirus, seadornavirus), previously detected only in china, livestock-infecting stretch lagoon virus (reovirus, orbivirus), two novel dimarhabdov ... | 2013 | 24314645 |
the changing epidemiology of kunjin virus in australia. | west nile virus (wnv) is a mosquito-borne virus responsible for outbreaks of viral encephalitis in humans and horses, with particularly virulent strains causing recent outbreaks of disease in eastern europe, the middle east and north america. a strain of wnv, kunjin (wnvkun), is endemic in northern australia and infection with this virus is generally asymptomatic. however in early 2011, an unprecedented outbreak of encephalitis in horses occurred in south-eastern australia, resulting in mortalit ... | 2013 | 24287851 |
the role of australian mosquito species in the transmission of endemic and exotic west nile virus strains. | recent epidemic activity and its introduction into the western hemisphere have drawn attention to west nile virus (wnv) as an international public health problem. of particular concern has been the ability for the virus to cause outbreaks of disease in highly populated urban centers. incrimination of australian mosquito species is an essential component in determining the receptivity of australia to the introduction and/or establishment of an exotic strain of wnv and can guide potential manageme ... | 2013 | 23965926 |
