| insect-specific virus discovery: significance for the arbovirus community. | arthropod-borne viruses (arboviruses), especially those transmitted by mosquitoes, are a significant cause of morbidity and mortality in humans and animals worldwide. recent discoveries indicate that mosquitoes are naturally infected with a wide range of other viruses, many within taxa occupied by arboviruses that are considered insect-specific. over the past ten years there has been a dramatic increase in the literature describing novel insect-specific virus detection in mosquitoes, which has p ... | 2015 | 26378568 |
| insect-specific flaviviruses: a systematic review of their discovery, host range, mode of transmission, superinfection exclusion potential and genomic organization. | there has been a dramatic increase in the number of insect-specific flaviviruses (isfs) discovered in the last decade. historically, these viruses have generated limited interest due to their inability to infect vertebrate cells. this viewpoint has changed in recent years because some isfs have been shown to enhance or suppress the replication of medically important flaviviruses in co-infected mosquito cells. additionally, comparative studies between isfs and medically important flaviviruses can ... | 2015 | 25866904 |
| 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 ... | 2015 | 26444264 |
| mosquito cell lines: history, isolation, availability and application to assess the threat of arboviral transmission in the united kingdom. | mosquitoes are highly effective vectors for transmission of human and animal pathogens. understanding the relationship between pathogen and vector is vital in developing strategies to predict and prevent transmission. cell lines derived from appropriate mosquito hosts provide a relatively simple tool for investigating the interaction between the host and viruses transmitted by mosquitoes. this review provides a brief overview of the development of mosquito cell lines, methods of isolation, their ... | 2014 | 25141888 |
| the insect-specific palm creek virus modulates west nile virus infection in and transmission by australian mosquitoes. | insect-specific viruses do not replicate in vertebrate cells, but persist in mosquito populations and are highly prevalent in nature. these viruses may naturally regulate the transmission of pathogenic vertebrate-infecting arboviruses in co-infected mosquitoes. following the isolation of the first australian insect-specific flavivirus (isf), palm creek virus (pcv), we investigated routes of infection and transmission of this virus in key australian arbovirus vectors and its impact on replication ... | 2016 | 27457250 |
| a new insect-specific flavivirus from northern australia suppresses replication of west nile virus and murray valley encephalitis virus in co-infected mosquito cells. | recent reports of a novel group of flaviviruses that replicate only in mosquitoes and appear to spread through insect populations via vertical transmission have emerged from around the globe. to date, there is no information on the presence or prevalence of these insect-specific flaviviruses (isfs) in australian mosquito species. to assess whether such viruses occur locally, we used reverse transcription-polymerase chain reaction (rt-pcr) and flavivirus universal primers that are specific to the ... | 2013 | 23460804 |
| bagaza virus inhibits japanese encephalitis & west nile virus replication in culex tritaeniorhynchus & cx. quinquefasciatus mosquitoes. | studies have shown that certain flaviviruses influence susceptibility of mosquitoes by inhibiting/enhancing replication of important flaviviruses. hence, a study was designed to determine whether bagaza virus (bagv), a flavivirus isolated from culex tritaeniorhynchus mosquitoes in india, alters susceptibility of cx. tritaeniorhynchus and cx. quinquefasciatus mosquitoes to japanese encephalitis (jev) and west nile viruses (wnv). | 0 | 26905241 |
| a new species of mesonivirus from the northern territory, australia. | here we describe casuarina virus (casv), a new virus in the family mesoniviridae. this is the first report of a mesonivirus in australia, which extends the geographical range of this virus family to 3 continents. the virus was isolated in 2010 from coquillettidia xanthogaster mosquitoes during surveillance in the suburbs of darwin, the capital of the northern territory. cryo-electron microscopy of the casv virions revealed spherical particles of 65 nm in size with large club-shaped projections o ... | 2014 | 24670468 |
| commensal viruses of mosquitoes: host restriction, transmission, and interaction with arboviral pathogens. | recent advances in virus detection strategies and deep sequencing technologies have enabled the identification of a multitude of new viruses that persistently infect mosquitoes but do not infect vertebrates. these are usually referred to as insect-specific viruses (isvs). these novel viruses have generated considerable interest in their modes of transmission, persistence in mosquito populations, the mechanisms that restrict their host range to mosquitoes, and their interactions with pathogens tr ... | 2017 | 28096646 |
| efficacy of residual insecticide biflex aquamax applied as barrier treatments for managing mosquito populations in suburban residential properties in southeast queensland. | the pyrethroid insecticide biflex aquamax (bifenthrin) was evaluated for its ability to suppress coastal mosquito populations in a controlled suburban backyard study in mango hill, queensland, australia. the insecticide was applied to perimeter vegetation, fencing in selected backyards, or both, and mosquito populations were monitored weekly from 3 wk before to 8 wk after treatment (11 wk total) by using cdc miniature light traps and human bait landing rates. in addition, bioassays were conducte ... | 2012 | 23025182 |
| a novel insect-specific flavivirus replicates only in aedes-derived cells and persists at high prevalence in wild aedes vigilax populations in sydney, australia. | to date, insect-specific flaviviruses (isfs) have only been isolated from mosquitoes and increasing evidence suggests that isfs may affect the transmission of pathogenic flaviviruses. to investigate the diversity and prevalence of isfs in australian mosquitoes, samples from various regions were screened for flaviviruses by elisa and rt-pcr. thirty-eight pools of aedes vigilax from sydney in 2007 yielded isolates of a novel flavivirus, named parramatta river virus (parv). sequencing of the viral ... | 2015 | 26519596 |
| effects of attachment substrate, larval diet, and temperature on development and survival of immature coquillettidia linealis (skuse) and coquillettidia xanthogaster (edwards). | a sustainable colony allowed investigations into attachment substrates, diet and temperature in the development of the immature stages of cq. linealis and its local congener cq. xanthogaster. as immatures, these mosquitoes attach to submerged plants for respiration, and various field-collected and laboratory-raised plants were compared with non-living substrates. hydroponically-grown wheat plant seedlings provided the most suitable attachment substrate. development and survival of immatures to e ... | 2019 | 31124241 |
| colonization of coquillettidia linealis (skuse) with reference to other coquillettidia and mansonia species. | the immature stages of coquillettidia and mansonia mosquitoes are cryptic and spend the duration of their development attached to the tissues of subsurface aquatic plants. this obligatory association makes them difficult to collect and has precluded detailed investigation of the biology of coquillettidia linealis, a species of significant pest and vector status in australia, as well as other species in the genus coquillettidia in australia and elsewhere. this paper describes the first successful ... | 2019 | 31124246 |
| 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 ... | 1997 | 9430109 |
