What is the primary purpose of Methoprene as a larvicide?

• A. To kill adult mosquitoes
• B. To prevent larvae from maturing
• C. To act as a systemic pesticide
• D. To enhance mosquito reproduction

Answer: (B)

Methoprene serves primarily as a larvicide by preventing mosquito larvae from maturing into adult mosquitoes. This substance works through a unique mechanism that mimics juvenile hormone, a vital hormone in the growth and development processes of insects. By interfering with the normal maturation and metamorphosis of mosquito larvae, Methoprene effectively halts their progression to adulthood, thereby reducing the population of mature, breeding mosquitoes capable of transmitting diseases. This method of pest control is advantageous as it specifically targets the larval stage without causing immediate harm to adult mosquitoes, which is particularly useful for managing populations in specific environments. It allows for greater control of mosquito populations over time, contributing to public health efforts in reducing vector-borne diseases.
