From: The transmission potential of Rift Valley fever virus among livestock in the Netherlands: a modelling study

Parameter Definition
1/φ h Average latent period of host
γ h * k Mean infectious period of host
h ) 2 * k Variance infectious period of host
ψ h Host mortality
1/μ v Aedes (T) = a 0 - a 1 T Longevity of Ae. vexans as function of temperature T
1/μ v Culex (T) = a 0 - a 1 T Longevity of Cx. pipiens as function of temperature T
d v Culex Increased mortality of infected Cx. pipiens
b(T) mosquitoes = b slope (T- b min ) Biting rate of mosquito species as function of temperature T
1/φ v Aedes (T) = 1/( φ max - φ slope T) Extrinsic incubation period Ae. vexans as function of temperature T. The slope is equal for Ae. vexans and Cx. pipiens.
1/φ v Culex (T) = 1/( φ max - φ slope T) Extrinsic incubation period Cx. pipiens as function of temperature T. The slope is equal for Ae. vexans and Cx. pipiens
ζ Vertical transmission Ae. vexans
β Aedes Host to Ae. vexans transmission probability
β Culex Host to Cx. pipiens transmission probability
α Aedes Ae. vexans to host transmission probability
α Culex Cx. pipiens to host transmission probability
π Aedes, j Relative preference of Ae. vexans for a host species j
π Culex, j Relative preference of Cx. pipiens for a host species j
