Recent studies have found that LEDs can be more efficient at attracting anopheline mosquitoes. Determining the population of any anopheline mosquito can provide data needed to target eradication efforts that can reduce the incidence of malaria.
Malaria is carried largely through mosquitoes in the genus Anopheles, which is made up of 465 species and distributed in tropical, subtropical, and temperate regions of the world.
Light traps are prioritized over bait traps, which expose collectors to potential pathogens and introduce human error to sampling techniques.
LEDs are cheaper and more efficient than other light sources. They're also more difficult to break, and have a longer operating life than incandescent bulbs.
