Outline of Final Research Achievements |
First, a coupled model with ecophysiological and climatological factors was developed to estimate the spatiotemporal distribution of the species of dominant malaria vectors (Anopheles spp.) in monsoon Asia, using simple climate data. Then, we examined how the potential distribution obtained from the model could explain trends in malaria incidence observed in India, which has the highest number of confirmed cases of malaria in Asia. As a result, it was found that malaria incidence tended to increase exponentially as vector generation number increased. In addition, the observed seasonal peak of malaria incidences corresponded closely to the simulated appearance period of vector species, except for intensively irrigated areas that experience anthropogenic impacts on hydrologic conditions. Therefore, a new, modified model that includes irrigation as a factor was developed to predict the active growing period of mosquitoes more precisely than the base.
