Where do European corn borer adults generally lay their eggs?

European corn borer adults typically lay their eggs on the underside of leaves. This behavior provides crucial protection for the eggs since the underside of the leaf is less exposed to environmental factors such as direct sunlight, rain, and predation from other insects. By laying eggs in this less conspicuous location, the European corn borer enhances the chances of survival for its offspring.

This egg-laying strategy is particularly relevant to their lifecycle and the potential impact on crops, especially corn, as the larvae that emerge will feed on the plant, causing damage. Understanding the behavior of the European corn borer in this context is vital for pest management and control practices in agriculture.
