What can heavy rainfall during egg hatch help control?

• A. Ant populations
• B. White grubs
• C. Sod webworms
• D. Chinch bugs

Answer: (D)

Heavy rainfall during egg hatch can significantly help control chinch bugs. When heavy rain occurs, it can lead to conditions that are unfavorable for chinch bug survival and development. Chinch bugs thrive in dry conditions, and excessive moisture can displace or drown the emerging nymphs before they can establish themselves. Additionally, heavy rainfall can create saturated soil conditions, which may hinder the movement of the pests and likewise disrupt their feeding habits. In contrast, the other pests listed have different life cycle traits and sensitivities that do not respond to heavy rainfall in the same way. For example, while white grubs might be somewhat affected by waterlogged conditions, they tend to be more resilient and spend part of their life cycle underground where they might not be as susceptible to drowning. Similarly, sod webworms often remain in the thatch layer of the turf and can survive through wet conditions. Ant populations also may thrive in various environmental conditions, and their management is typically not directly influenced by egg hatch during rain events. Thus, the impact of heavy rainfall aligns more closely with the control of chinch bugs due to their specific life cycle and habitat preferences.
