Which trap is described as the most common and oldest and requires a 110V power source?

• A. New Jersey light trap
• B. CO2 trap
• C. Standing red box
• D. Mosquito magnet trap

Answer: (A)

The key idea here is how mosquito surveillance traps are powered and what has historically dominated programs. The New Jersey light trap is a long-standing, widely used design that runs on standard 110V AC. It uses a lamp to attract mosquitoes at night and a small fan powered by that same electricity to pull mosquitoes into a collection container. Because of its simplicity, robustness, and long history in public health programs, it became the most common trap and is considered one of the oldest options used for monitoring mosquito populations.

CO2-based traps are effective but newer and often more resource-intensive, requiring gas sources or propane and more complex setups. The standing red box and Mosquito Magnet traps are other modern or specialized designs with different attractants or power needs, not the historical standard.
