There is plenty of help available to anyone interested in
identifying, monitoring and controlling insect and disease pests
that are impacting urban trees. 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. Three others that have been long-
time favorites with arborists and provide self-help information
useful to nonprofessionals
