The increasing trend of environmental change is dramatically changing malaria pattern at the local and as well as global scales. Malaria situation is worsening with large-scale epidemics and increasing mortality. For other contributions one can refer to the enclosed list. There are six major vectors of malaria, they differ greatly in their biology, breeding habitats and distribution. Looking to the vast areas, the reports on vector distribution, which is an essential component of selective malaria control strategy are scanty and old.
Manual surveys are very costly, cumbersome and time consuming.
Therefore GIS was used to map distribution of coastal malaria vector An. sundaicus in India. The species is well known for its close association with coastal conditions. Its major breeding sites are swamps, creeks and pits containing stagnant brackish water. It is the sole malaria vector in Andamans and Nicobar islands. Different vector species establish their population at different heights where ecology is suited for their survival.
