In addition to warm weather, what environmental condition can influence mosquito proliferation?

The correct answer is standing water availability, as it plays a crucial role in mosquito proliferation. Mosquitoes require standing water to reproduce, as it serves as the breeding ground for their larvae. Females lay their eggs in or near stagnant water sources, including ponds, puddles, and even containers that hold water. The presence of standing water not only supports the life cycle of mosquitoes but also creates an environment conducive to their development and survival.

While factors like cold temperatures, low humidity levels, and high altitudes can impact mosquito activity or limit their range, they do not directly facilitate reproduction as standing water does. Cold temperatures can inhibit their activity, low humidity can lead to desiccation of eggs and larvae, and high altitudes may be less hospitable due to lower oxygen levels and a cooler climate, which are not optimal for their lifecycle. In contrast, ensuring there is standing water available directly correlates with an increased mosquito population, driving home the importance of this environmental condition in their proliferation.
