Natural refractoriness in malaria vector and non-vector mosquitoes is an ancestral virtue. My research involves dissecting genetic causes of refractoriness in malaria vector and non-vector mosquitoes of Afro-tropical region, An. gambiae complex. I use molecular genetics and proteomic approaches to isolate candidate genes conferring refractoriness, and use RNAi technology for functional the candidate genes, e.g. depleting of peritrophic membrane genes on Anopheles gambiae to determent their effects on midgut invasion by plasmodium parasite. My researchs involve colonisation and maintaining mosquito population, genetic crossing between different mosquito lines and infections of female mosquitoes with rodent malaria parasites P. berghei or human malaria parasite P. falciparum. In the past, I had researched on the interactions between malaria-vectors, humans and livestock in a typical rural African village with the aim to develop insecticide treated cattle for integrated control of vector born diseases of human and livestock. My future research interest is possibility of using symbiotic bacteria as a vehicle to deliver dsRNA of targeting gene/s that affect physiological or vectorial efficiency of medically or economically important insects.
