This study was designed to determine the peak period of infective mosquito biting and thus the greatest potential for filarial transmission to occur. It was found that biting density, natural infection, and infectivity rates of Culex quinquefasciatus were significantly higher in the third quadrant of the night (from midnight to 3:00 am) than at other times. This was true in both an urban and a rural environment. Avoidance of mosquito bite by any means during this time period might reduce and limit filarial transmission to a great extent.
