What is the best time to scout for corn rootworm larvae?

The best time to scout for corn rootworm larvae is early July because this is when the larvae are most likely to be actively feeding on corn roots. By this time, the eggs that were laid by adult beetles in the previous summer will have hatched, and the larvae will have emerged to begin their critical feeding phase, which usually occurs from late June to early July. During this period, the damage caused by rootworms can be most significant, as the larvae impact root development, subsequently affecting the yield potential of the corn plants. Scouting at this time allows for early detection and management decisions to be implemented if necessary. This is essential for preventing significant crop damage before it has occurred or for understanding the current pressure of rootworm populations in the field.
