Mathematical modelling of mosquito dispersal in a heterogeneous environment

► A discrete space continuous-time model of mosquito dispersal is developed. ► Larval and host seeking stages have the most effect on mosquito population growth. ► Dispersal and spatial heterogeneity affect distribution and population dynamics. ► The distance moved by mosquitoes is dependent on the dispersal rate. ► Random distribution of spatial repellents reduces the distance moved by mosquitoes.
