Trait

Equation

Reference

EIP of S. tundra in mosquitoes

1/((T-14)/130)

[10, 12, 13]

Blood meal digestion rate (biting rate)

1/(0.0943 + 0.0043*T)

[32]

Survival rate of mosquitoes

e-1/(-4.4 + 1.31*Tmean – 0.03*(Tmean)^2)

[21, 33]

Daily maximum survival rate is set as 90%

  1. Abbreviations: T, temperature (hourly, °C); Tmean, daily mean temperature (°C)
