Which insect larvae primarily affect corn during late spring to early summer?

The Western corn rootworm is known to primarily affect corn during late spring to early summer. This insect's larvae feed on corn roots, which can significantly impact the plant's health and yield. As the corn plants begin to establish themselves in the early growing season, the presence of these larvae can lead to root damage, diminishing the plant's ability to absorb nutrients and water. This timing is critical as it aligns with the period when corn is most vulnerable, making the Western corn rootworm a key pest to monitor during this phase of corn growth.

In contrast, other insects such as the black cutworm, southern corn rootworm, and common stalk borer may affect corn, but their peak damage timing, feeding habits, or target plants vary. Understanding the life cycle and specific timing of pest invasions is essential for effective management and mitigating risks to corn crops.
