Vector Competence of Northern European Culex pipiens Biotype pipiens and Culex torrentium to West Nile Virus and Sindbis Virus

Viruses, 2023
The West Nile Virus (WNV) and Sindbis virus (SINV) are avian-hosted mosquito-borne zoonotic viruses that co-circulate in some geographical areas and share vector species such as Culex pipiens and Culex torrentium.

The mosquito Aedes aegypti requires a gut microbiota for normal fecundity, longevity and vector competence

Communications Biology, 2023
A study of the mosquito Aedes aegypti indicates normal adult longevity, reproduction and vector competence to transmit dengue virus depends on having a gut microbiota that can provision B vitamins.

Role of the Microbiome in Aedes spp. Vector Competence: What Do We Know?

Viruses, 2023
Aedes aegypti and Aedes albopictus are the vectors of important arboviruses: dengue fever, chikungunya, Zika, and yellow fever. Female mosquitoes acquire arboviruses by feeding on the infected host blood, thus being able to transmit it to their offspring.

Biotechnological Potential of Microorganisms for Mosquito Population Control and Reduction in Vector Competence

Insects, 2023
Simple Summary Mosquitoes carry pathogens that can cause diseases like malaria, dengue fever, chikungunya, yellow fever, and Zika fever, causing more than 700,000 deaths each year around the world.

Host competence, interspecific competition and vector preference interact to determine the vector-borne infection ecology

Frontiers in Ecology and Evolution, 2022
Understanding how ecological interactions affect vector-borne disease dynamics is crucial in the context of rapid biodiversity loss and increased emerging vector-borne diseases.

Evaluating vector competence for Yellow fever in the Caribbean. [PDF]

Nat Commun
AbstractThe mosquito-borne disease, Yellow fever (YF), has been largely controlled via mass delivery of an effective vaccine and mosquito control interventions. However, there are warning signs that YF is re-emerging in both Sub-Saharan Africa and South America.

The effect of temperature on dengue virus transmission by Aedes mosquitoes

Frontiers in Cellular and Infection Microbiology, 2023
Dengue is prevalent in tropical and subtropical regions. As an arbovirus disease, it is mainly transmitted by Aedes aegypti and Aedes albopictus. According to the previous studies, temperature is closely related to the survival of Aedes mosquitoes, the ...

Age-structured vectorial capacity reveals timing, not magnitude of within-mosquito dynamics is critical for arbovirus fitness assessment

Parasites & Vectors, 2020
Background Transmission dynamics of arboviruses like Zika virus are often evaluated by vector competence (the proportion of infectious vectors given exposure) and the extrinsic incubation period (EIP, the time it takes for a vector to become infectious),

Estimating the magnitude and direction of altered arbovirus transmission due to viral phenotype. [PDF]

PLoS ONE, 2011
Vectorial capacity is a measure of the transmission potential of a vector borne pathogen within a susceptible population. Vector competence, a component of the vectorial capacity equation, is the ability of an arthropod to transmit an infectious agent ...

Exploring the Mosquito–Arbovirus Network: A Survey of Vector Competence Experiments

bioRxiv, 2022
Arboviruses receive heightened research attention during major outbreaks, or when they cause unusual or severe clinical disease, but are otherwise under-characterized.
