We investigated the interaction between insect-specific virus, Piura virus (PIUV), and arbovirus Zika (ZIKV) in Aedes albopictus cells. performed coinfection experiments C6/36 (Cor 33 strain, Colombia) ZIKV (PRVABC58 Puerto Rico) were co-inoculated into cells using two multiplicity of infection (MOI) combinations: 0.1 for both viruses 1.0 ZIKV, PIUV. Wells infected triplicate with either PIUV coinfection, ZIKV-only, or PIUV-only. Mock served as control wells. The cell suspension was collected daily 7 days post-infection. load titrated by TCID50 on Vero 76 ZIKV-only also quantified RT-qPCR. whether interfered replication. suppressed replication resulting a 10,000-fold reduction titers within 3 viral loads not reduced presence ZIKV. conclude that, when concurrently infected, suppresses while does interfere

Aedes aegypti and Ae. albopictus are important human arbovirus vectors that can spread arboviral diseases such as yellow fever, dengue, chikungunya Zika. These two mosquito species coexist on Hainan Island the Leizhou Peninsula in China. Over past 40 years, distribution of these areas has gradually expanded, while declined sharply. Monitoring their genetic diversity diffusion could help to explain influence behind this phenomenon became key controlling epidemic arboviruses.To better understand differentiation mosquitoes, possible cohabiting were searched between July October 2021, five populations collected. Respectively nine 11 microsatellite loci used for population analysis albopictus. In addition, mitochondrial coxI gene was also selected both species.The results showed mean index (PIC SI values) (mean PIC = 0.754 1.698) higher than 0.624 1.264). The same observed gene: all (total H 45 Hd 0.89958 vs. total 23 0.76495, respectively). UPGMA dendrogram, DAPC STRUCTURE analyses divided into three clusters two. Mantel test indicated a significant positive correlation distance geographic (R2 0.0611, P 0.001), but not 0.0011, 0.250).The aegypti. terms future vector control, most effective measure control monitor dynamics Peninsula, which theoretically support further elimination
