This manual was designed to help you identify and control damaging pests of Christmas trees in the North Central and Northeastern regions of the United States. Most of the information provided also applies to the States and Canadian Provinces that border these regions. You do not have to be a pest specialist to use this information. The manual was written in everyday language so that anyone with an interest in Christmas trees can read and understand it. Because it is meant to be a tool and not a textbook, we included only the basic information that you need to know to diagnose and manage pest problems in your plantations. In addition to the illustrated pest profiles, you will find practical advice on: * How to look for and recognize potential pests * How to select, plant, and care for trees so they are less likely to be damaged by pests * How to keep pests at low levels to prevent tree damage The management techniques we provide will discourage pests and prevent them from causing serious damage.
