Dengue Exposure and wMel Strain Affects the Fertility of Quiescent Eggs of .

(1) Background: The deployment of the bacterium to reduce arbovirus transmission is ongoing in several countries worldwide. When -carrying are released and established in the field, females may feed on dengue-infected hosts. The effects of simultaneous exposure on life-history traits of to wMel strain and dengue-1 virus DENV-1 remain unclear.

Zika Virus Infection Produces a Reduction on Lifespan but No Effects on Mosquito Fecundity and Oviposition Success.

A Zika virus (ZIKV) pandemic started soon after the first autochthonous cases in Latin America. Although is pointed as the primary vector in Latin America, little is known about the fitness cost due to ZIKV infection. We investigated the effects of ZIKV infection on the life-history traits of females collected in three districts of Rio de Janeiro, Brazil (Barra, Deodoro, and Porto), equidistant ~25 km each other.

The impact of the age of first blood meal and Zika virus infection on Aedes aegypti egg production and longevity.

The impact of senescence and pathogen infection on Aedes aegypti life-history traits remains poorly understood. This laboratory study focused on the impact of Zika virus (ZIKV) infection and the age of first blood intake on blood meal and clutch sizes, and more importantly on the egg production ratio per μL of blood. Three groups of ZIKV-infected and uninfected Ae.
