A note on insecticide susceptibility status of Anopheles fluviatilis James (Diptera: Culicidae) in Rayagada District of Odisha, India

Purpose of the Research: The aim of this study was to evaluate the adulticidal activity of DDT (4%) and deltamethrin (0.05%) against Anopheles fluviatilis during September 2013? November 2013 in Rayagada, a malaria endemic district of Odisha state, India and to select the insecticide to be used for routine national malaria control programme based on the results of the susceptibility test. Methods Used: Susceptibility test was done as per the standard WHO susceptibility tests. Results: The results showed that An. fluviatilis is susceptible to both the commonly used insecticides DDT and deltamethrin in the study area. Discussion: An. fluviatilis is the vector species primarily associated with transmission of malaria in the study area, and successful application of DDT and deltamethrin in the district could reduce the vector load.
