Vector Biology & Control A. Vectors Genetics and Bionomics Laboratory Principal Investigator: Dr Nutan Nanda, Scientist F Research Staff: Mr. Ravinder Singh Technical Assistant Mr. Krishan Gopal Technical Assistant Mr. Ram Kanwar Technician A Mr. Kanwar Singh Technician A Mr. Ram Kumar Temporary status worker Vectors genetics and bionomics lab under vector biology and control division of NIMR is mainly engaged in research related to biology and bionomics of malaria vector at sibling species level; mapping the distribution of sibling species, study of their biological traits and role in malaria transmission in different eco-epidemiological zones of the country. This section has made significant contribution in discovery of new sibling species in An. fluviatilis, An. culicifacies & An. sundaicus complexes using cytotaxonomic techniques and the development of new tools for identification of sibling species. The biological attributes of malaria vectors at sibling species level has provided valuable information on variations in distribution pattern, resting and feeding preferences, response to insecticides used in public health and the malaria transmission potential among sibling species which has been employed in malariogenic stratification of different geographical regions of the country. Studies have also been undertaken on the role of geoclimatic, entomological, parasitological and socio-economic factors for understanding the complexity of malaria transmission dynamics in different ecological settings in malaria endemic areas. The integration of basic and applied research has proved useful in planning situation specific / effective vector control strategies for interruption of malaria transmission.
