Which statement about mosquito light traps is true?

The statement that mosquito light traps attract adults from a considerable area is accurate because these traps emit light that can draw insects from distances away. Mosquitoes are naturally attracted to specific wavelengths of light, particularly UV light, which these traps often emit. This attraction allows them to cover a larger radius than some other methods of mosquito collection. Traps can be placed strategically to benefit from this property, and their effectiveness can result in capturing a significant number of adult mosquitoes across a broad area.

Regarding the other statements, light traps do not generally depend on competing light sources for effectiveness; rather, they are designed to stand out as the primary light source in the vicinity. While it is true that many mosquitoes are more active at night, it's not entirely accurate to classify these traps as ineffective during the day; they may be less effective but can still catch some mosquitoes. Lastly, light traps are capable of attracting both male and female mosquitoes, although the species attracted may vary, making the assertion that they only attract males incorrect.
