What is Vector Control?
Historical Background
Key Points
10 points- 1.
Includes methods such as insecticide spraying, larviciding, and environmental management.
- 2.
Insecticide spraying targets adult mosquitoes to reduce their population.
- 3.
Larviciding targets mosquito larvae in breeding sites to prevent them from developing into adults.
- 4.
Environmental management involves eliminating mosquito breeding sites, such as stagnant water.
- 5.
Use of mosquito nets, especially insecticide-treated nets (ITNs), to protect people from mosquito bites.
- 6.
Personal protection measures, such as using insect repellent and wearing long sleeves and pants.
- 7.
Community participation in vector control activities.
- 8.
Integrated vector management (IVM) approach, which combines multiple control methods.
- 9.
Monitoring and evaluation of vector control interventions.
- 10.

Frequently Asked Questions
61. What is Vector Control, and why is it important for UPSC GS Paper 2 and GS Paper 3?
Vector control refers to methods used to limit or eradicate organisms that transmit diseases, such as mosquitoes, ticks, fleas, and rodents. It's crucial for preventing vector-borne diseases like malaria, dengue, and Zika. For UPSC, it's important for GS Paper 2 (Health) and GS Paper 3 (Science and Technology). Questions can cover methods, challenges, and technology's role.
Exam Tip
Remember the definition and examples of vector-borne diseases for prelims. For mains, focus on the methods and challenges.
2. What are the key provisions of Vector Control?
The key provisions include:
- •Insecticide spraying to target adult mosquitoes.
- •Larviciding to target mosquito larvae in breeding sites.
- •Environmental management to eliminate mosquito breeding sites.
- •Use of mosquito nets, especially insecticide-treated nets (ITNs).
Exam Tip
Focus on understanding the different methods and their specific targets (adult mosquitoes vs. larvae).
3. How has Vector Control evolved over time?
Vector control has evolved from early methods like draining swamps and using mosquito nets to modern methods using insecticides and other technologies developed in the 20th century. Recent developments include new insecticides to combat resistance, genetically modified mosquitoes, and spatial repellents.
Exam Tip
Note the shift from basic environmental methods to technology-driven solutions.
4. What are the different types of Vector Control methods?
Vector control methods include:
- •Insecticide spraying (adulticides)
- •Larviciding
- •Environmental management (source reduction)
- •Use of mosquito nets (ITNs)
- •Use of genetically modified mosquitoes
- •Application of spatial repellents
Exam Tip
Classify the methods based on their target (adults, larvae, environment).
5. What are the challenges in the implementation of Vector Control programs in India?
Challenges include:
- •Insecticide resistance in vector populations.
- •Logistical difficulties in reaching remote areas.
- •Lack of community participation.
- •Funding constraints.
- •Coordination issues between different government agencies.
Exam Tip
Consider socio-economic factors and geographical challenges while answering this question.
6. How does India's Vector Control compare with other countries?
India's vector control is primarily managed by the National Vector Borne Disease Control Programme (NVBDCP). Comparisons with other countries would require specific data not provided. However, challenges like insecticide resistance and resource constraints are common globally.
Exam Tip
Focus on the role of NVBDCP and the general challenges faced by developing countries.
