What is the role of methoprene briquettes in mosquito management?

• A. To kill adult mosquitoes directly
• B. To prevent mosquito oviposition
• C. To disrupt the development of mosquito larvae
• D. To attract adult mosquitoes

Answer: (C)

Methoprene briquettes play a crucial role in mosquito management by disrupting the development of mosquito larvae. Methoprene is a juvenile hormone analog that mimics the natural hormones in insects, preventing larvae from maturing into adult mosquitoes. When these briquettes are placed in water bodies where mosquitoes breed, the active ingredient disperses into the water, impacting the growth of larvae. This not only hinders their development but ultimately reduces the adult population, contributing to an effective strategy for mosquito control. This method is particularly beneficial because it targets the larval stages before they can emerge as adults, making it a proactive approach in mosquito management. Additionally, using methoprene supports integrated pest management (IPM) practices by minimizing the use of chemical insecticides that target adult mosquitoes, thus helping with environmental and public health considerations.
