Light Trap
Light traps attract mosquitoes looking for a blood meal. The attractants used are light and carbon dioxide (CO2), in the form of dry ice or as compressed gas in canisters. These traps are useful for providing information about the mosquito species found in the area under surveillance. Because they attract mosquitoes looking for a blood meal that may have just emerged and never had a blood meal previously, the likelihood of finding a virus in these mosquitoes is much reduced.
