Dry ice is used in which trap to attract mosquitoes for virus testing?

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

Answer: (A)

Carbon dioxide is a primary cue mosquitoes use to locate a host. Dry ice releases CO2 as it sublimates, creating a steady plume that mimics a breathing animal. This CO2 plume is very effective at drawing host-seeking mosquitoes into a trap for collection and virus testing. A trap that uses dry ice to provide that CO2 emission is the CO2 trap, making it the best choice. Other traps rely on different attractants—light for some traps, visual cues for others, or CO2 from propane in Mosquito Magnet devices—not specifically the dry-ice CO2 source, which is why the CO2 trap is the correct match.
