Which statement about immature mosquito control is TRUE?

Source reduction is considered a key strategy for controlling larval populations of mosquitoes because it involves eliminating or reducing standing water where mosquitoes breed. This method is effective because immature mosquitoes, or larvae, develop in water. By reducing or removing these breeding sites, the potential for mosquitoes to reproduce is significantly decreased, leading to a lower overall mosquito population. This approach is often more sustainable and environmentally friendly compared to relying solely on chemical interventions.

In contrast, the other options do not accurately reflect effective strategies for controlling immature mosquitoes. Space spraying insecticides primarily targets adult mosquitoes, not larvae, while chemical agents may not be effective at all life stages, particularly for larvae. Insect growth regulators, on the other hand, are specifically designed to affect immature stages rather than adults, which highlights the effectiveness of targeted interventions like source reduction in larval control.
