How can environmental factors influence pest populations?

• A. They have no effect on pests
• B. Only humidity affects pest populations
• C. Temperature and humidity can impact life cycles and reproduction
• D. Seasonal changes affect pests while temperature does not

Answer: (C)

Environmental factors play a crucial role in influencing pest populations, particularly through temperature and humidity, which can significantly affect their life cycles and reproduction rates.

Temperature is a key factor that influences metabolic rates in insects, impacting their development speed, reproductive cycles, and survival rates. Warmer temperatures can accelerate growth, leading to more generations per season, while colder temperatures may slow down development and reduce population size.

Humidity also plays an essential role, as many pests thrive under specific moisture conditions. High humidity can enhance breeding and survival rates for certain pests, while low humidity can lead to desiccation and higher mortality rates.

Together, these environmental factors create a dynamic ecosystem in which pest populations can thrive or diminish based on the prevailing conditions. Adaptability to these changes is essential for pest management and control strategies. In contrast, the other options suggest limited or no influence of these environmental factors, which does not accurately reflect their significant impact on pest dynamics.
