Control of fall webworm

, : Control of fall webworm. Research Report Series, Alabama Agricultural Experiment Station, Auburn University (5): 24

The arctiid Hyphantria cunea is a pest of shade, fruit and ornamental trees in North America and Mexico. In Alabama, there are 2 generations of the pest a year, one in spring and the other in late summer. Larvae pass through as many as 11 instars. Layers of silk are spun over the surface of the leaf as soon as larvae start feeding, and eventually ends of several branches are webbed together. Nests of the pest are unsightly, and one or more branches may be defoliated.
