Diurnal pattern of human-biting activity and transmission of subperiodic Wuchereria bancrofti (Filariidea: Dipetalonematidae) by Ochlerotatus niveus (Diptera: Culicidae) on the Andaman and Nicobar islands of India.

We monitored diel-landing periodicity (biting activity/cycle) of Ochlerotatus niveus and the infection/infectivity pattern through human-landing collections on Teressa Island, which is remotely located in the Nicobar district of the Andaman and Nicobar group of Islands of India, for a period of one year. The biting activity was seen throughout the day, exhibiting a bimodal peak, the first at dawn (4:00-6:00 AM) and the other towards dusk (5:00-6:00 PM). This pattern was similar during all the seasons of the year.
