Answer 1

Step 1: Understanding the Concept:
Control of vector-borne diseases like malaria primarily involves breaking the transmission link by targeting the mosquito population.
Step 2: Detailed Explanation:
1. Source Reduction: Avoid stagnation of water in and around residential areas (coolers, flower pots, ditches) because mosquitoes breed in stagnant water.
2. Personal Protection: Use of mosquito nets, wire mesh on doors/windows, and mosquito repellents to prevent bites.
3. Biological Control: Introducing fish like \textit{Gambusia} in ponds that feed on mosquito larvae.
Step 3: Final Answer:
Effective measures include stagnant water management and using physical barriers like mosquito nets.
