Feeding and mating strategies in anopheles (Diptera: Culicidae): theoretical modeling approach

The effects of various ecological factors, such as the probability of finding mates and hosts and of successfully obtaining a blood meal, on the mating and feeding strategies of domestic female anopheline mosquitoes was investigated using theoretical models. The models calculated the mean fitness of 1,000 nonblood-fed, anautogenous, virgin anophelines. One model simulated females that always mate before blood feeding, whereas another simulated females that are able to feed opportunistically if a host was detected before they mated. The models demonstrated highest fitness for mosquitoes capable of opportunistic feeding under nearly all simulated conditions. This advantage increased as the probability of finding hosts and mates decreased as a function of host and mate availability.
