The WHO-recommended strategy for dengue vector control that targets larval breeding sites in water storage containers is called:
- A Space spraying with malathion
- B Source reduction and larviciding ✓
- C Indoor residual spraying (IRS)
- D Release of sterile male mosquitoes (SIT)
Correct answer: B. Source reduction and larviciding
Explanation
Source reduction (emptying, cleaning, or covering water storage containers that serve as breeding sites for Aedes aegypti) combined with larviciding using temephos or Bacillus thuringiensis israelensis is the cornerstone of dengue vector control. Space spraying is a reactive measure during outbreaks but has limited effectiveness. IRS is used primarily for malaria. Sterile insect technique (SIT) is an emerging, not routine, strategy.
