Which mosquito trapping method is the least selective regarding species, sex, and feeding behavior?

The correct choice is based on the broad capture capabilities of CDC traps. These traps work by attracting mosquitoes using carbon dioxide and other attractants, allowing them to capture a wide variety of mosquito species regardless of their specific feeding behaviors or sexes. Unlike other trapping methods that might target specific mosquitoes, CDC traps cast a wider net, making them less selective.

Light traps primarily attract nighttime flying insects, which could limit the capture to certain species that are active and attracted to light. Pigeon baited traps rely heavily on the presence of pigeons to lure mosquitoes, which may exclude many species that do not feed on the birds. Truck traps, while effective in capturing mosquitoes, tend to be more situational based on the routes used and may also miss certain populations based on their environmental preferences.

The broad catch strategy of the CDC traps is beneficial in surveillance and research settings, where understanding the full range of mosquito populations is essential for effective vector control and disease monitoring.
