Author(s): P.K. Sumodan

Abstract: Aedes (Stegomyia) albopictus has been widely reported to be a predominantly diurnal and outdoor feeder from different parts of the world. Studies conducted in Kerala during May 2012- December 2013 showed this species exhibiting nocturnal endophagy during May to August. Highest per night density was obtained in July (2.2 and 1.5 in 2012 and 2013 respectively), followed by June (1.9 and 1.3 in 2012 and 2013 respectively). Indoor biting during day and night did not show significant difference. Maximum biting activity was observed between 22:30-23:00 hours (75 mosquitoes). This was followed by the period between 20:30-21:00 hours (65 mosquitoes). Further studies should be conducted to establish the significance of this behaviour in relation to disease transmission.
