Anopheles maculatus s.l as potential malaria vectors with opportunistic feeding in Meghalaya, Northeast India

analysis revealed significant genetic differentiation between An. maculatus s.s. populations from the Khasi Hills Region (KHR) and Garo Hills Region (GHR), further supported by haplotype network analysis. Additionally, blood meal analysis of specimens collected from cattle sheds during evening resting hours indicated diverse host feeding patterns: 15% had fed on humans, 16% on cattle, and 17% on both. The presence of mixed blood meals suggests that An. maculatus s.s. exhibits opportunistic and flexible feeding behaviour. These results provide molecular evidence of malaria transmission by specific members of the Maculatus Group in Meghalaya, underscoring their epidemiological importance. The genetic divergence and feeding plasticity highlight the need for targeted vector control in the region.

Abstract

analysis revealed significant genetic differentiation between An. maculatus s.s. populations from the Khasi Hills Region (KHR) and Garo Hills Region (GHR), further supported by haplotype network analysis. Additionally, blood meal analysis of specimens collected from cattle sheds during evening resting hours indicated diverse host feeding patterns: 15% had fed on humans, 16% on cattle, and 17% on both. The presence of mixed blood meals suggests that An. maculatus s.s. exhibits opportunistic and flexible feeding behaviour. These results provide molecular evidence of malaria transmission by specific members of the Maculatus Group in Meghalaya, underscoring their epidemiological importance. The genetic divergence and feeding plasticity highlight the need for targeted vector control in the region.
