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.
This study offers an opportunity to strategically target surveillance and control programmes and thereby augment efforts to reduce arbovirus burden in human populations globally.
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.
Potential of Aedes albopictus as a bridge vector for enzootic pathogens at the urban-forest interface in Brazilby dos Santos et al.
Results from this study show that Ae. albopictus frequency declines as it penetrates into the forest and highlight its potential role as a bridge vector of zoonotic diseases at the edge of the Brazilian forests studied.
The authors performed an experimental oral infection with the Asian genotype of ZIKV in Ae. albopictus from La Réunion and found a strong midgut barrier to dissemination. This result is discussed in the light of previous vector competence assays for DENV and CHIKV performed on other Ae. albopictus populations from La Réunion.
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.
