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 ...200415861235
mycobacterium ulcerans in mosquitoes captured during outbreak of buruli ulcer, southeastern australia.buruli ulcer (bu) occurs in >30 countries. the causative organism, mycobacterium ulcerans, is acquired from the environment, but the exact mode of transmission is unknown. we investigated an outbreak of bu in a small coastal town in southeastern australia and screened by pcr mosquitoes caught there. all cases of bu were confirmed by culture or pcr. mosquitoes were trapped in multiple locations during a 26-month period. bu developed in 48 residents of point lonsdale/queenscliff and 31 visitors fr ...200718217547
complete mtdna genomes of anopheles darlingi and an approach to anopheline divergence time.the complete sequences of the mitochondrial genomes (mtdna) of members of the northern and southern genotypes of anopheles (nyssorhynchus) darlingi were used for comparative studies to estimate the time to the most recent common ancestor for modern anophelines, to evaluate differentiation within this taxon, and to seek evidence of incipient speciation.201020470395
genetic characterization of k13965, a strain of oak vale virus from western australia.k13965, an uncharacterized virus, was isolated in 1993 from anopheles annulipes mosquitoes collected in the kimberley region of northern western australia. here, we report its genomic sequence, identify it as a rhabdovirus, and characterize its phylogenetic relationships. the genome comprises a p' (c) and sh protein similar to the recently characterized tupaia and durham viruses, and shows overlap between g and l genes. comparison of k13965 genome sequence to other rhabdoviruses identified k1396 ...201121740935
household survey of container-breeding mosquitoes and climatic factors influencing the prevalence of aedes aegypti (diptera: culicidae) in makkah city, saudi investigate the prevalence of container breeding mosquitoes with emphasis on the seasonality and larval habitats of aedes aegypti (ae. aegypti) in makkah city, adjoining an environmental monitoring and dengue incidence.201223569860
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
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 ...201324314645
mosquito consumption by insectivorous bats: does size matter?insectivorous bats have often been touted as biological control for mosquito populations. however, mosquitoes generally represent only a small proportion of bat diet. given the small size of mosquitoes, restrictions imposed on prey detectability by low frequency echolocation, and variable field metabolic rates (fmr), mosquitoes may not be available to or profitable for all bats. this study investigated whether consumption of mosquitoes was influenced by bat size, which is negatively correlated w ...201324130851
foraging ranges of insectivorous bats shift relative to changes in mosquito abundance.the need to develop effective management strategies for insectivorous bat populations requires an understanding of factors influencing habitat use. availability of pest prey, such as mosquitoes is likely to be one such factor. to assess whether this is the case, we radio-tracked vespadelus vulturnus thomas (little forest bat), a predator of aedes vigilax skuse (saltmarsh mosquito), in saltmarsh and adjacent coastal swamp forest during periods of high and low ae. vigilax abundance. when mosquito ...201323667699
analysis of arbovirus isolates from australia identifies novel bunyaviruses including a mapputta group virus from western australia that links gan gan and maprik viruses.the mapputta group comprises antigenically related viruses indigenous to australia and papua new guinea that are included in the family bunyaviridae but not currently assigned to a specific genus. we determined and analyzed the genome sequences of five australian viruses isolated from mosquitoes collected during routine arbovirus surveillance in western australia (k10441, sw27571, k13190, and k42904) and new south wales (12005). based on matching sequences of all three genome segments to prototy ...201627764175
genetic characterization of archived bunyaviruses and their potential for emergence in better understand the diversity of bunyaviruses and their circulation in australia, we sequenced 5 viruses (gan gan, trubanaman, kowanyama, yacaaba, and taggert) isolated and serologically identified 4 decades ago as members of the family bunyaviridae. gan gan and trubanaman viruses almost perfectly matched 2 recently isolated, purportedly novel viruses, salt ash and murrumbidgee viruses, respectively. kowanyama and yacaaba viruses were identified as being related to members of a large clade ...027088588
mitochondrial genome sequences reveal deep divergences among anopheles punctulatus sibling species in papua new guinea.members of the anopheles punctulatus group (ap group) are the primary vectors of human malaria in papua new guinea. the ap group includes 13 sibling species, most of them morphologically indistinguishable. understanding why only certain species are able to transmit malaria requires a better comprehension of their evolutionary history. in particular, understanding relationships and divergence times among anopheles species may enable assessing how malaria-related traits (e.g. blood feeding behavio ...201323405960
using next-generation sequencing for dna barcoding: capturing allelic variation in its2.internal transcribed spacer 2 (its2) is a popular dna barcoding marker; however, in some animal species it is hypervariable and therefore difficult to sequence with traditional methods. with next-generation sequencing (ngs) it is possible to sequence all gene variants despite the presence of single nucleotide polymorphisms (snps), insertions/deletions (indels), homopolymeric regions, and microsatellites. our aim was to compare the performance of sanger sequencing and ngs amplicon sequencing in c ...201727799340
molecular identification of mosquitoes (diptera: culicidae) in southeastern australia.dna barcoding is a modern species identification technique that can be used to distinguish morphologically similar species, and is particularly useful when using small amounts of starting material from partial specimens or from immature stages. in order to use dna barcoding in a surveillance program, a database containing mosquito barcode sequences is required. this study obtained cytochrome oxidase i (coi) sequences for 113 morphologically identified specimens, representing 29 species, six trib ...201627217948
full genome sequencing and genetic characterization of eubenangee viruses identify pata virus as a distinct species within the genus orbivirus.eubenangee virus has previously been identified as the cause of tammar sudden death syndrome (tsds). eubenangee virus (eubv), tilligery virus (tilv), pata virus (patav) and ngoupe virus (ngov) are currently all classified within the eubenangee virus species of the genus orbivirus, family reoviridae. full genome sequencing confirmed that eubv and tilv (both of which are from australia) show high levels of aa sequence identity (>92%) in the conserved polymerase vp1(pol), sub-core vp3(t2) and outer ...201222438872
the gecko: an environmentally friendly biological agent for mosquito control.laboratory experiments with aedes aegypti mosquitoes investigated the effects of light, mosquito density and physiological state on predation rates by the australian gecko gehydra dubia and the exotic asian house gecko hemidactylus frenatus. for both gecko species a positive correlation was demonstrated between prey density and the predation rate. using ae.aegypti males and unfed females as prey in a terrarium (0.054 m3), consumption rates reached 76-108/day for g.dubia and 63-109/day for h.fren ...19979430109
seasonal activity, vector relationships and genetic analysis of mosquito-borne stratford virus.there are many gaps to be filled in our understanding of mosquito-borne viruses, their relationships with vectors and reservoir hosts, and the environmental drivers of seasonal activity. stratford virus (strv) belongs to the genus flavivirus and has been isolated from mosquitoes and infected humans in australia but little is known of its vector and reservoir host associations. a total of 43 isolates of strv from mosquitoes collected in new south wales between 1995 and 2013 was examined to determ ...201728253306
is there a risk of malaria transmission in nsw?nsw has a putative malaria vector in anopheles annulipes, and increased numbers of immigrants from malaria endemic countries who may be infective to mosquitoes but asymptomatic. we examine the factors known to influence malaria transmission and conclude that local transmission is possible but unlikely. the public health implications are that there should be systematic screening of immigrants from malaria endemic countries on arrival, and that the public health capacity to identify and respond to ...200819007544
mosquito (diptera: culicidae) and arbovirus activity on the south coast of new south wales, australia, in investigation of the seasonal activity of adult mosquitoes and arboviruses in two native forests revealed a mosquito fauna comprising 33 species for the mogo state forest-batemans bay locality and 34 species for the termeil state forest. the mosquito aedes vigilax was the most abundant species in salt marshes at mogo state forest-batemans bay, whereas the freshwater species anopheles annulipes s.l. and coquillettidia linealis were most abundant at termeil state forest. major faunal difference ...19911685192
ross river virus risk associated with dispersal of aedes (ochlerotatus) camptorhynchus (thomson) from breeding habitat into surrounding residential areas: muddy lakes, western australia.rapid population growth in western australia has resulted in increased development of land for residential housing, and new developments are often proposed close to water because of intrinsic aesthetic values. however, this placement may place future residents at risk of mosquito-borne disease, of which ross river virus (rrv) disease is the most common in australia. mosquito dispersal data were combined with a spatial analysis of human rrv cases to show that mosquitoes dispersed readily from lar ...201424799370
