CHIKV = chikungunya virus; DENV = dengue virus; VC = vectorial capacity.

*

Mosquitoes held at mean temperature cycles or cycles specific to trap location (site).

Proportion of mosquitoes taking at least two blood meals during their lifetime.

Probability of daily survival.

§

Vector competence = proportion of mosquitoes with disseminated infections by day 21 postinfection.

Extrinsic incubation period in days.

VC = h*b*pn.

#

Transmission not detected, value indicates limit of detection.
