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: Understanding Anti-Larval Measures
Anti-larval measures are crucial for controlling vector-borne diseases and encompass several strategies:
- Environmental control (A): This involves eliminating or managing larval breeding grounds.
- Biological control (B): Utilizing natural predators or pathogens to manage larval populations.
- Residual sprays (C): Applying long-lasting insecticides.
- Genetic control (D): Manipulating vector genetics to decrease their population sizes.
