ABSTRACT
Larval ecology of Anopheles dirus, the main vector of forest malaria in north-eastern region of India, was studied in relation to physico-chemical characteristics of its breeding habitats in a rain forest area of Assam, India. Shady stream side pools, positive for the breeding of An. dirus, had significantly higher amounts of total hardness (P < 0.024) in comparison to negative pools of similar type. When compared with An. dirus negative breeding habitats, in hot-wet as well as in cool-dry seasons, An. dirus positive shady ground pools showed higher mean values of total alkalinity, hardness and chloride content, whereas lower pH, dissolved oxygen along with higher total alkalinity and hardness were possessed by An. dirus positive stream side pools. Specificity of breeding habitats of An. dirus in relation to its ecology has been discussed.
