Aedes aegypti, the vector for dengue and chikungunya, is best described by which of the following characteristics?

• A Nocturnal biter breeding in polluted drains and cesspools
• B Night biter breeding in wells and overhead tanks
• C Crepuscular biter breeding in puddles and ground pools
• D Daytime biter breeding in artificial containers with clean water ✓

Explanation

Aedes aegypti is a daytime biter with peak biting activity in early morning and late evening. It breeds in artificial containers holding clean water such as discarded tires, flower pots, water storage tanks, and coconut shells in urban and semi-urban settings. This anthropophilic, container-breeding behavior distinguishes it from Anopheles (night biter, clean water) and Culex (nocturnal, polluted water).
