Which pest spins webs over the outer leaves of pecan trees?

1. Chinchbugs

2. Fall webworm

3. Japanese beetles

4. Eastern tent caterpillar

The correct answer is: Fall webworm

The fall webworm is known for spinning webs over the outer leaves of pecan trees. This pest creates a webbing that typically encases the leaf clusters at the ends of the branches, providing a protective barrier for the caterpillars inside. The webs can cover large areas and are noticeable during the late summer months, often resulting in significant defoliation if left uncontrolled. The impact of fall webworms extends beyond just aesthetics; as they feed on the foliage, they can weaken the tree and make it more susceptible to other pests and diseases. Their presence is an indication of potential damage if populations are not managed. Understanding the behavior and signs of this pest is essential for effective pest management in pecan production.
