Insect-specific viruses belonging to significant arboviral families have recently been discovered. These viruses appear to be maintained within the insect population without the requirement for replication in a vertebrate host. Mosquitoes collected from Badu Island in the Torres Strait in 2003 were analysed for insect-specific viruses. A novel bunyavirus was isolated in high prevalence from Culex spp. The new virus, provisionally called Badu virus (BADUV), replicated in mosquito cells of both… Expand
High Prevalence of a Newly Discovered Wutai Mosquito Phasivirus in Mosquitoes from Rio de Janeiro, Brazil
TLDR
The detection and characterization of a recently discovered bunyavirus corresponding to the Wutai mosquito phasivirus is described, for the first time in South America, and its high prevalence in the Culex spp. Expand
Antigenic Characterization of New Lineage II Insect-Specific Flaviviruses in Australian Mosquitoes and Identification of Host Restriction Factors
TLDR
The data are the first to uncover the mechanisms that restrict the growth of Lin II ISFs in vertebrate cells and provides new insights into the evolution of these viruses and the mechanisms associated with host switching that may allow new mosquito-borne viral diseases to emerge. Expand
A Unique Relative of Rotifer Birnavirus Isolated from Australian Mosquitoes
The family Birnaviridae are a group of non-enveloped double-stranded RNA viruses which infect poultry, aquatic animals and insects. This family includes agriculturally important pathogens of poultryExpand
Detection and characterisation of novel vector-borne viruses in Mozambique
TLDR
Overall, viral metagenomics was successfully used to detect and characterise the viromes of important vectors (mosquitoes and ticks) from Mozambique and constitute the basis for further studies on viruses that are circulating in vectors and on the evolution, viral maintenance and transmission of pathogenic arboviruses. Expand
New genotypes of Liao ning virus (LNV) in Australia exhibit an insect-specific phenotype.
TLDR
High rates of virus detection in progeny reared from infected adult female mosquitoes, coupled with visualization of the virus within the ovarian follicles by immunohistochemistry, suggest that LNV is transmitted transovarially. Expand
Insect-Specific Viruses: A Historical Overview and Recent Developments.
TLDR
These insect-specific viruses have tremendous potential as agents for biocontrol of vectors and or viruses of medical importance and present novel opportunities in the fields of viral evolution and viral/vector interaction. Expand
Insect-Specific Viruses: An overview and their relationship to arboviruses of concern to humans and animals.
TLDR
An update of the general characteristics of ISVs and their interaction with arboviruses that infect vertebrates is provided and it is suggested that ISVs may be used as an alternative tool for biological control, development of vaccines, and diagnostic platforms for arbeviruses. Expand
Understanding the Mechanisms Underlying Host Restriction of Insect-Specific Viruses
TLDR
The vertebrate restriction factors include the genetic elements of ISVs (structural and non-structural genes and the untranslated terminal regions), vertebrate host factors (agonists and antagonists), and the temperature-dependent microenvironment. Expand

TLDR
Findings of an immense genetic diversity of bunyaviruses in non-blood feeding arthropods support the hypothesis of an arthropod origin of vertebrate-pathogenic bunyviruses. Expand
Commensal Viruses of Mosquitoes: Host Restriction, Transmission, and Interaction with Arboviral Pathogens
TLDR
It is shown that many ISVs are efficiently transmitted directly from the female mosquito to their progeny via infected eggs, and, moreover, that persistent infection of mosquito cell cultures or whole mosquitoes with ISVs can restrict subsequent infection, replication, and transmission of some mosquito-borne viral pathogens.

A New Insect-Specific Flavivirus from Northern Australia Suppresses Replication of West Nile Virus and Murray Valley Encephalitis Virus in Co-infected Mosquito Cells
TLDR
It is demonstrated that prior infection of cultured mosquito cells with PCV suppressed subsequent replication of the medically significant West Nile and Murray Valley encephalitis viruses by 10–43 fold, suggesting that superinfection exclusion can occur between ISFs and vertebrate-infecting flaviviruses despite their high level of genetic diversity.

TLDR
Phylogenetic analyses revealed that CxFV is closely related to the insect flaviviruses associated with Aedes mosquitoes, Cell fusing agent (CFA) and Kamiti River virus (KRV). Expand
Characterization of a novel Negevirus and a novel Bunyavirus isolated from Culex (Culex) declarator mosquitoes in Trinidad.
TLDR
Isolation and characterization of these viruses increase the knowledge of the geographical distribution, diversity and host range of mosquito-specific bunyaviruses and negeviruses. Expand
Genetic and phenotypic characterization of the newly described insect flavivirus, Kamiti River virus
TLDR
The isolation of KRV demonstrates the presence of an insect-only flavivirus in nature and raises questions regarding potential interactions between this virus and other mosquito-borne viruses in competent vector populations. Expand
Isolation of a new strain of the flavivirus cell fusing agent virus in a natural mosquito population from Puerto Rico.
TLDR
Results from viral screening, and cell culture and molecular identification of the infected mosquitoes are presented, supporting previous suggestions of the existence of a large number of unsampled flaviviruses and elucidating the mechanism by which flaviviral sequences may have integrated into mosquito genomes.

Evolutionary and phenotypic analysis of live virus isolates suggests arthropod origin of a pathogenic RNA virus family
TLDR
These data, together with ancestral state reconstruction of bunyavirus hosts for major virus lineage bifurcations, suggest that the vertebrate-infecting viruses evolved from arthropod-specific progenitors. Expand
Eilat virus, a unique alphavirus with host range restricted to insects by RNA replication
TLDR
A unique alphavirus, Eilat virus (EILV), isolated from a pool of Anopheles coustani mosquitoes from the Negev desert of Israel is described and seems to be mosquito-specific and represents a previously undescribed complex within the genus Alphavirus. Expand
Novel Virus Discovery and Genome Reconstruction from Field RNA Samples Reveals Highly Divergent Viruses in Dipteran Hosts
TLDR
It is clear that viral transmission and maintenance cycles in nature are likely to be significantly more complex and taxonomically diverse than previously expected. Expand
