Two 1 yr surveys carried out at a gap of 10 yr revealed nine anopheline species from malaria endemic foothills area of Ayodhya - Baghmindi range of West Bengal, India, with 8.4 per cent populations of Anopheles culicifacies. An. culicifacies was incriminated as vector of Plasmodium falciparum with sporozoite rate of 1.23 per cent. Studies on age composition indicated that proportion parous and daily survival rate of An. culicifacies were assessed to be 0.50 and 0.84 respectively. The survival rate per gonotrophic cycle averaged over the two year was 0.61. Rainy season was found to be the favourable period for transmission.
