Aedes aegypti mosquito is the primary vector for dengue. The key characteristic that distinguishes it from other Aedes species used in vector surveillance is:

• A Breeds exclusively in fresh water streams
• B Bites only at night
• C Bites during the day and breeds in artificial domestic water containers ✓
• D Has a natural predator in Gambusia fish

Explanation

Aedes aegypti is a day-biting (diurnal) mosquito with two peak activity periods: 2 hours after sunrise and 2 hours before sunset. It breeds in small, clean domestic water containers (flower pots, water storage tanks, discarded tyres, coolers). This peridomestic breeding makes source reduction (eliminating standing water) the primary dengue control strategy. Gambusia fish are used to control Anopheles larvae.
