Landscape - Insects Currently Active

The following are some insects now active in the landscape in Delaware to be on the watch for.

Dogwood borers appeared in Longwood pheromone traps this week. Four-lined plant bug damage to shrubs perennials has been noted in one or two spots. It appears as small circular holes that look like buckshot on new, but fully expanded leaves. Damage occurred several weeks ago so the control window is gone. Fletcher scale and white prunicola scale crawlers are emerging.. Control crawlers with a foliar absorbed insecticide. Redheaded flea beetle adults are out and feeding. Bagworms have hatched and are feeding now.

Information from the Ornamentals Hotline from the University of Delaware Cooperative Extension.
