This is the first report of the presence of L1014S (homologous to the kdr-e in An. gambiae) and a novel mutation V1010L (resulting from G-to-T or -C transversions) in the VGSC of An. culicifacies in addition to the previously described mutation L1014F.
The study demonstrates the ability of An. culicifacies species E, the major vector of falciparum and vivax malaria in Sri Lanka, to oviposit and breed in brackish water. The sibling species B in the An. subpictus complex, a well-known salt water breeder and a secondary malaria vector in the country, was also detected at the same site. Since global warming and the rise in sea levels will further increase of inland brackish water bodies, the findings have significant implications for the control of malaria in Sri Lanka and elsewhere.
The Roll Back Malaria Partnership has developed the Global Malaria Action Plan for a substantial reduction in the burden of malaria and its eradication in the long term.
The present attempt is made to study and compare the fecundity of the differentially susceptible members of the An. culicifacies complex.
