CDFA Pest Prevention Plant Regulation Practice Exam

What type of climate does the European corn borer prefer?

1. Cold Climate

2. Moderate Climate

3. Hot and Humid Climate

4. Dry Climate

The correct answer is: Hot and Humid Climate

The European corn borer thrives in hot and humid climates, as this environment provides the necessary conditions for its growth and reproduction. These pests typically favor warm temperatures that support their lifecycle, especially during the larval stage when they feed on crops like corn. Humidity is also important because it facilitates their development and increases survival rates through various life stages. In climates that are too cold, the European corn borer may struggle to survive and reproduce effectively. Moderate climates may not provide the consistent warmth and humidity needed for optimal growth, while dry climates lack the necessary moisture that supports their lifecycle. Thus, the preference of the European corn borer for hot and humid conditions is crucial for understanding its behavior, lifecycle, and the potential threats it poses to agricultural crops.
