Bulletin #56: Help Stop Insect & Disease Invasions

There is plenty of help available to anyone interested in joining the effort to monitor and control insect and disease pests that are impacting urban trees throughout the nation.


Here are two “must have” books for anyone seriously interested in identifying tree pests. Both are nationwide in coverage, highly illustrated and over 500 pages in length. They are published by Comstock Publishing Associates, a division of Cornell University Press. These books are particularly valuable for identifying and learning the life cycles of the pests and tree species associated with each pest. These books do not include control suggestions. For the latter, local sources such as your county extension agent or a reputable arborist are the best places to start.

  • Insects that Feed on Trees and Shrubs by Warren T. Johnson and Howard H. Lyon.
  • Diseases of Trees and Shrubs by Wayne A. Sinclair, Howard H. Lyon and Warren T. Johnson.

Other Publications

There is a wealth of leaflets and booklets available on every insect and disease, usually published by government agencies. For example, “Pest Alerts” are single-page leaflets covering the major pests currently threatening America’s trees. These are published by the U.S. Forest Service, Northeastern Area State and Private Forestry. The annual report by USDA Forest Health Protection scientists is Major Forest Insect and Disease Conditions in the United States.
