摘要

Based on the number of calls and emails I have received lately on fall webworm infestations I thought this would be a good topic for this month's column The fall webworm.

In the United States it has been recorded to feed on at last 88 species of trees and shrubs Feeding preferences can vary depending on location and unfortunately in Texas it seems to prefer pecan.
