Which of the following correctly describes the breeding and biting behaviour of Aedes aegypti?

• A Breeds in polluted stagnant water and bites predominantly outdoors at dusk
• B Breeds in vegetated pond margins attached to aquatic plants and bites at dawn
• C Breeds in brackish coastal waters and bites throughout the night
• D Breeds in clean stagnant water in man-made containers and bites predominantly during daytime, often indoors ✓

Explanation

Aedes aegypti is a domestic, day-biting mosquito that rests indoors and lays eggs in clean stagnating water held in man-made containers such as storage jars, tyres, coconut shells, flower vases and desert coolers. Its flight range is short, around 100 metres. Polluted water is the habitat of Culex quinquefasciatus, brackish coastal water suits Anopheles sundaicus, and vegetation-bound ponds are the domain of Mansonia species.
