Relative abundance of Culex quinquefasciatus (Diptera: Culicidae) with reference to infection and infectivity rate from the rural and urban areas of East and West Godavari districts of Andhra Pradesh, India.

This paper describes the seasonal abundance of Culex quinquefasciatus in the rural and urban areas of the East and West Godavari districts (EGDT and WGDT) of Andhra Pradesh, India. The per man-hour density (PMHD) was collected from seven units in EGDT and two units in WGDT, which comprised rural and urban areas. The highest infection and infectivity rates were found in the rural areas of Rajahmundry (43.6%) and Amalapuram (13.2%) respectively. In urban areas, the highest infection and infectivity rates were found in Rajahmundry: 7.5% and 3.6% respectively. There was considerable difference in the infection rate and infectivity rates between the rural areas and urban areas in each unit.
