Which statement about resting boxes is accurate?

• A. They attract resting mosquitoes during daylight.
• B. They attract resting mosquitoes at night.
• C. They are used to measure larval density only.
• D. They have no practical use in surveillance.

Answer: (A)

Resting boxes are designed to sample adult mosquitoes by providing a daytime resting site. Mosquitoes often rest in sheltered, shady places during the day after feeding, so these boxes lure resting adults when temperatures are warm and humidity is moderate. By collecting mosquitoes from these boxes, you gain information about the adult population and species present, which helps gauge vector activity and the impact of control measures. They’re not used to measure larval density—that requires larval habitat surveys and dipping—and they do have practical surveillance value, unlike the idea that they only attract mosquitoes at night or have no role in monitoring.
