IE,t (UE,t)

Number of newly produced I (U) female embryos at time t

Iα,t(Iβ,t)

Number of I reproductive females with α (β) mitochondrial background

Uα,t(Uβ,t)

Number of U reproductive females with α (β) mitochondrial background at time t

p t

Frequency of reproductive I females at time t, IA,t/(IA,t+UA,t)

αI,t(βI,t)

Frequency of α (β) background in reproductive I females at time t, that is, Iα,t/IA,t and Iβ,t/IA,t

αU,t(βU,t)

Frequency of α (β) background in reproductive U females at time t, that is, Uα,t/UA,t and Uβ,t/UA,t

sI(sU)

Probability of I juvenile (U juvenile) post egg stage becoming a reproductive adult (irrespective of CI)

δI(δU)

Probability of I (U) eggs surviving to larval stage

τIU)

Average length of the pre-reproductive period for I (U); reproduction begins at τI+1 (τU+1)

vI(vU)

Daily survival rate of I (U) reproductive adults

μ

Probability of an infected female producing uninfected offspring (maternal leakage)

ξ

Probability of paternal transmission of Wolbachia

m

Emigration/immigration rate of mosquitoes between two populations per generation

a, c

Parameters for larval density-dependent mortality

ω

Length (in days) of pre-reproductive period spent as egg

κ

Length (in days) of pre-reproductive period spent as pupae and pre-reproductive adult

bI(bU)

Number of female embryos produced by an Infected, I (Uninfected, U) female per day

H
