Evolution and biological significance of flaviviral elements in the genome of the arboviral vector Aedes albopictusby Houé et al.
Results from this study show a complex association between NIRVS and DENV/CHIKV opening a new avenue for investigating the functional role of NIRVS as antiviral elements shaping vector competence of mosquitoes to arboviruses.
Transmission potential of African, Asian and American Zika virus strains by Aedes aegypti and Culex quinquefasciatus from Guadeloupe (French West Indies)by Hery et al.
Culex quinquefasciatus mosquitoes from Guadeloupe are not able to experimentally transmit ZIKV. It was also noticed better transmission of ZIKV strain from Senegal by Ae. aegypti from Guadeloupe compared to Malaysia and Martinique strains.
The recent discovery of endogenized elements shows that virus/vector interactions are more dynamic than previously thought, and genetic markers such as NIRVS could be one of the potential targets to reduce arbovirus transmission.
According to the authors of this study, mosquito control measures should remain focused on the mosquito Ae. aegypti which is also the vector of CHIKV and DENV, and much more research effort should be allocated to fill the knowledge gaps about this virus.
Infection of a French Population of Aedes albopictus and of Aedes aegypti (Paea Strain) with Zika Virus Reveals Low Transmission Rates to These Vectors’ Salivaby Ryckebusch et al.
This study shows that the extrinsic incubation period of Ae. aegypti for transmission is shorter than that of Ae. albopictus.
