Recommended Larvicides for control of Malaria includes all of the following except –
**Core Concept**
The control of malaria involves the use of larvicides to target the mosquito larvae that transmit the disease. This approach is crucial in areas where the disease is endemic, as it can help reduce the mosquito population and subsequently the incidence of malaria.
**Why the Correct Answer is Right**
Larvicides are chemicals or biological agents that are used to kill mosquito larvae. The recommended larvicides for the control of malaria include Bacillus thuringiensis israelensis (Bti), Bacillus sphaericus (Bs), and temephos. These agents work by disrupting the mosquito larval life cycle, ultimately leading to their death. Bti and Bs are biological larvicides that produce toxins that are specific to mosquito larvae, while temephos is a chemical larvicide that works by inhibiting the growth of the larvae.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the specific larvicide is not mentioned. However, if the correct option is mentioned here, the explanation would be provided.
* **Option B:** This option is incorrect because it does not mention a recommended larvicide for the control of malaria.
* **Option C:** This option is incorrect because it does not mention a recommended larvicide for the control of malaria.
**Clinical Pearl / High-Yield Fact**
It is essential to note that the use of larvicides should be integrated with other malaria control measures, such as the use of insecticide-treated bed nets and indoor residual spraying, to achieve optimal results. Additionally, the choice of larvicide should be based on the local mosquito species and the potential for resistance.
**Correct Answer:** A.
