Question

Anti-larval measures to control vector-borne diseases include which of the following? A. Environmental Control B. Biological Control C. Residual Sprays D. Genetic Control

• A. A and B only
• B. C and D only
• C. A, B, C and D
• D. B, C and D only

Hint:

Effective vector control often involves a combination of methods targeting different stages of the vector's lifecycle.

Answer 1

The Correct Option is C

Step 1: Understand the anti
-larval measures.
Anti
-larval measures to control vector
-borne diseases involve several strategies:
- Environmental control (A) includes removing or managing breeding sites.
- Biological control (B) uses natural predators or pathogens to control larval populations.
- Residual sprays (C) involve the application of insecticides that remain effective for a long time.
- Genetic control (D) involves manipulating the genetics of vectors to reduce their populations.
