Which of the following types of mosquitoes can be controlled by removing & destroying the aquatic plants by herbicides?
## **Core Concept**
The question targets the understanding of vector control methods, specifically focusing on the breeding habits of different mosquito species. Mosquitoes have distinct preferences for breeding sites, which can include various types of water bodies with or without vegetation.
## **Why the Correct Answer is Right**
The correct answer, **C. Anopheles**, is associated with breeding in areas that often have aquatic plants. Anopheles mosquitoes, which are the primary vectors of malaria, prefer clean, well-oxygenated water with vegetation for breeding. Removing and destroying aquatic plants with herbicides can disrupt their breeding sites, thereby controlling their population.
## **Why Each Wrong Option is Incorrect**
- **Option A:** Aedes mosquitoes typically breed in small, artificial containers that collect water, such as flowerpots, tires, and bird baths. These sites are not necessarily associated with aquatic plants.
- **Option B:** Culex mosquitoes breed in a variety of water bodies, including polluted waters and areas with organic matter. While they can be found in areas with vegetation, their breeding is not exclusively dependent on the presence of aquatic plants.
- **Option D:** Mansonia mosquitoes also lay their eggs on the undersurface of aquatic plants. However, the most effective control method mentioned in the question, removing & destroying aquatic plants by herbicides, is specifically beneficial for controlling Anopheles.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that vector control is a critical component of disease prevention. Understanding the specific breeding habits of different mosquito species is essential for implementing effective control measures. For Anopheles mosquitoes, eliminating aquatic plants can significantly reduce their breeding sites.
## **Correct Answer:** C. Anopheles.
