Table 1.
Rates of infection (IR), dissemination (DR), transmission (TR), and efficiency of dissemination (DE) and transmission (TE) from Ae. albopictus infected with CHIKV 06.21_E1-A226V for the two groups (control group and second blood meal group) at both constant (CT) and fluctuating (FT) temperature regimes at 7 and 10 days post-infection (dpi). The ranges of PFU measured (min-max) for saliva in the two groups and two temperature sets are also reported.
