True or False: To control mosquito immature stages, chemical agents should always be the first choice.

The statement that chemical agents should always be the first choice for controlling mosquito immature stages is false. Integrated Pest Management (IPM) principles emphasize a holistic approach to pest control, which prioritizes preventive measures and non-chemical methods before resorting to chemical solutions.

For mosquito management, it is often more effective to focus on ecological methods such as source reduction, which involves eliminating standing water where mosquitoes breed. Additionally, deploying biological control agents, like certain fish species or microorganisms that target mosquito larvae, can provide a sustainable option. Chemical treatments, while effective, can lead to resistance in pest populations, disrupt non-target organisms, and pose environmental risks when overused. Therefore, considering various control strategies in a balanced manner is essential, as chemical agents should not be the default first choice.
