Book Description
Insect and disease detection surveys were made June 18-19 and August 12-13, 1975 on the Monongahela National Forest, West Virginia, by personnel from the Forest Insect and Disease Management, S&PF, Delaware Field Office (DFO), and Monongahela National Forest (MNF). The purpose of the surveys was to detect and delineate forest insect and disease activity within the forest boundary. There are no serious insect or disease problems on the Monongahela National Forest. The fall cankerworm and oak leaf tier caused most of the damage in the form of light to moderate defoliation. Pest activity on the forest does not warrant further evaluation now.

Book Description
It is a great honor and indeed a privilege for me to write the Foreword to this book, the first of its kind from the Forest Products Research Institute The study of forest insects is now becoming a matter of great concern to many people all over the world because insects damage the already depleted forests and forest resources. In Ghana very little interest was shown in the insects of forest trees and products. But as forest practices have become more intensive so also have the pests on the crops increased and the damage caused increased to alarming proportions. Foresters are now becoming in creasingly aware of the immense havoc that some of these insects can cause. To aid the fight against the pests they have to be fully identified and studied so that effective control measures can be implemented. It is in an effort to bridge this gap in our knowledge that one welcomes this book by Professor Michael R. Wagner, Dr. S.K.N. Atuahene and Dr.
