The national malaria control agency sends in a new person to develop a malarial control strategy. (S)he recommends draining the lakes and ponds, and intensive house spraying. Discuss the pros and cons of each option, and argue why they should or should not be implemented. In your answer consider effects on species A, species B, malaria incidence, and the local population. And remember, the idea is to help the local population
Background: An area has two different Anopheles species, species A and species B. Both can vector Plasmodium, although Plasmodium develops best and is transmitted best by species B. Species A is dominant because its larvae outcompete species B in the main shared breeding sites, small lakes, and ponds. Therefore the population of B is currently small. The small lakes and ponds are also the source for the main food source in the region, fish, grown in fish farms. There is grazing land, but other than chickens, the local population does not have livestock. Species A is largely endophilic, species B is exophilic. In other localities, species A and B will also feed on cattle, and B appears to prefer cattle. Both species like to roost during the hot day in rock overhangs and small caves.
