Host feeding patterns of Anopheles culicifacies species A and B

Countercurrent immunoelectrophoresis was used to assay bloodmeals to determine the host specificity of Anopheles culicifacies species A and B, collected from areas in Delhi, Uttar Pradesh and Bihar. Results indicated the predominantly zoophagic nature of species A and B with a relatively higher degree of anthropophagy for species A. Further, the human blood index was found to be related to the proportion of human and cattle population in an area. This study is significant because, of the two species only species A was incriminated as the vector of malaria in these areas.
