Mosquito feeding cycle. The cycle is divided into three parts a) the host searching process: mosquitoes complete the cycle within τ1 days and survive this process with a probability p1. They may visit animals or humans at a probability H(= Q(0)). They may encounter humans protected by ITNs at a probability φ. If so, mosquitoes may successfully bite at a probability s, die after landing on the net at a probability d or repeat the host searching cycle at a probability r until they successfully feed. b) Once mosquitoes have successfully fed they rest during τ2 days and survive at a probability p2.
