What seasonal changes occur that influence mosquito populations?

The correct answer highlights how temperature increases and heightened rainfall during spring and summer create ideal conditions for mosquito populations to thrive. Warm temperatures accelerate the life cycle of mosquitoes, leading to faster reproduction rates. Additionally, increased rainfall provides abundant breeding sites, as standing water in puddles, ponds, and containers becomes available for mosquitoes to lay their eggs. These seasonal changes contribute significantly to the growth and abundance of mosquito populations, particularly during warmer months when they are most active.

Conversely, the other options present conditions that are less favorable for mosquito populations. Cold temperatures and reduced rainfall can lead to mosquito eggs or larvae dying off or becoming inactive. Consistent temperatures throughout the year, without fluctuations, might not provide the necessary seasonal cues that trigger the mosquito life cycle. Decreased humidity in fall can also lead to unfavorable conditions for mosquitoes, as they generally prefer humid environments for survival and reproduction. Understanding these ecological influences is crucial for managing and controlling mosquito populations effectively.
