Entomological determinants of malaria transmission in an epidemic prone area of District Nuh (Haryana state), India.

Entomological determinants of malaria transmission in an epidemic prone area of District Nuh (Haryana state), India. J Vector Borne Dis. 2017 Oct-Dec;54(4):334-340 Authors: Nanda N, Singh SP, Prajapati BK, Ranjan K, Kar NP, Sharma SK, Valecha N Abstract Background & objectives: Entomological investigations were carried out in highly malarious villages under Ujina PHC of District Nuh (Haryana state) which is an epidemic prone area in northwestern region of India. The study was aimed to have an in-depth understanding of the entomological parameters influencing malaria transmission in the study area. Methods: The seasonal prevalence and biological attributes of vector mosquitoes were investigated during 2015 and 2016. Indoor resting vector mosquitoes were collected from human dwellings/cattle sheds and morphologically identified. Anopheles culicifacies were categorized to sibling species by species-specific inversions in polytene chromosomes and An. stephensi to ecological races on the basis of ridge number on egg float. The blood meal source analysis and incrimination studies of vectors were done by counter-current immunoelectrophoresis and enzyme-linked immunosorbent assay, respectively. Insecticide susceptibility test on vectors was performed as per WHO guidelines. Results: Seasonal abundance of An. culicifacies and An. stephensi in the study area showed variation; the peak densities of both the vectors were obser...
