What is the impact of urbanization on mosquito populations?

Urbanization significantly impacts mosquito populations, primarily by creating more breeding sites. As cities develop, areas such as construction sites, abandoned lots, and poorly managed stormwater systems can lead to the formation of stagnant water sources, which are ideal breeding grounds for mosquitoes.

In urban settings, human activities often result in increased water accumulation in containers, clogged drains, and other urban features that retain water. These environments can foster the proliferation of mosquitoes, increasing their population density. Urban areas can also present additional factors like changes in land use, which may inadvertently support mosquito habitats.

The other options do not accurately reflect the typical effects of urbanization on mosquito populations. For instance, urbanization does not commonly decrease standing water availability; instead, it often increases it through poor drainage and human-made structures. Similarly, while some urban settings may have a reduction in natural predators due to habitat loss, this does not universally lead to a reduced overall mosquito population. Instead, it can exacerbate mosquito breeding, particularly when there are fewer natural controls in place.
