How does the introduction of droughts affect mosquito populations?

The introduction of droughts typically leads to a temporary reduction in mosquito populations primarily because drought conditions create a lack of suitable breeding sites. Mosquitoes lay their eggs in standing water, and during periods of drought, many of these habitats dry up, making it difficult for mosquito populations to reproduce and thrive.

With decreased water levels, the survival rates of both larvae and adult mosquitoes are negatively impacted, as their developmental stages require water. Consequently, this results in fewer mosquitoes being born, thus leading to a decline in their overall numbers during drought conditions.

Other possible effects, like migration or a complete die-off, may occur under certain specific contexts or conditions, but the lack of breeding sites due to drought is the most significant and immediate factor influencing mosquito populations.
