Members of the mosquito genus Anopheles are competent vectors for human malaria. A total of about 13 species of anophelines transmit this disease in different regions of India. Primary vectors of malaria in north-eastern region of India belong to two species, (Anopheles dirus and Anopheles Recd. 28 June, 2001; in final form 3 Sept., 2001 minimus). Various aspects of complex life cycle of vectors are affected by different ecological factors like rainfall, temperature, humidity, water quality, vegetation and socio-economic conditions of the affected regions. To get a better understanding of how malaria varies in a community as a result of seasonal or annual changes in environmental factors, a study of environmental conditions and its spatial linkages is imperative for the planning of malaria control programmes at regional as well as national level. Both spatial and temporal changes in environmental conditions are important
