Vector competence for CVV with high versus low titer blood meals. Mosquitoes were provided low titer (lt) (1.2 × 10³ to 4.6 × 10³ pfu/ml) or high titer (ht) (1.6 × 10⁵ to 5.5 × 10⁷ pfu/ml) infectious blood meals. After 14 days, the mosquitoes were dissected and the number infected (% mosquitoes with virus in the body), disseminated (% mosquitoes with virus in legs and wings, independent of infections status) and transmitting (% mosquitoes with virus in saliva expectorant, independent of infection statues) were determined using Vero cell plaque assay. aAedes albopictus (lt: n = 21; ht: n = 34). bAedes triseriatus (lt: n = 55; ht: n = 29). cAedes japonicus (lt: n = 21; ht: n = 74). dAedes aegypti (lt: n = 44; ht: n = 52). Data are presented as mean % infected, disseminated and transmitting. *P < 0.01, **P < 0.001 and ns, not significant by two-tailed Fischer’s exact test
