New Jersey 7A Pest Control Practice Exam

Weather conditions are a significant factor influencing pest populations due to their direct impact on the life cycles, behavior, and survival of pests. Temperature, humidity, and rainfall can either promote or limit the growth of various pest species. For instance, warmer temperatures may accelerate reproduction rates, while excessive rainfall can lead to waterlogged environments that either aid in pest proliferation or create unfavorable conditions that reduce their populations. Changes in weather can also affect the availability of food sources and habitats for pests, ultimately impacting their survival and reproduction.

While soil pH, human consumption of pests, and plant growth rates do play roles in the ecosystem, they have a more indirect influence on pest populations compared to the immediate and varying impacts of weather conditions. Soil pH can affect plant health and consequently influence pest populations, but it does not directly change pest behaviors or populations as weather can. Human consumption of pests can control certain populations but is not a widespread or consistent factor. Plant growth rates can influence the amount of food available for pests, but this is secondary to how weather conditions can directly alter pest survival and reproduction.
