The Gyspy Moth and the Homeowner (FS-242)

The gypsy moth caterpillar is the most serious threat to forests comprised of oak in the United States. Gypsy moths reach greatest densities where oaks are the most abundant trees. If you have oak trees on your property, gypsy moths pose a threat to the beauty and value of your land.

Japanese Maple Scale: A Pest of Nursery and Landscape Trees and Shrubs (FS-967)

Unless Japanese Maple Scale (JMS) is monitored carefully and controlled early, populations of this armored scale can spread throughout a nursery or landscape to many species of woody plants and build up to levels that cause dieback and even death of infested plants.
