Introduced to the technical aspects of forestry aerial spraying in the mid-1970's, we were immediately impressed by the complexity of the process of delivering pesticide to foliage. At that time, there was a vigorous public debate in New Brunswick about the ecological and public h~alth impacts of the annual spray program for the control of defoliation of spruce and fir trees by the spruce budworm. The forest industry is important to the province and changes to the established procedures of budworm control could have major economic implications. A rational debate required reliable information about the mechanics of the spraying process. There was a need to supply missing information as to required pesticide application rates, atomizer performance, off-target drift and deposit, and the effects of weather and aircraft operating factors. We were invited to initiate a research program in this domain by New Brunswick forest management officials, and what follows in this book is a logical and quantitative description of the overall process based on our own research and that of others over the intervening years. After a short introduction to aerial spraying, we begin (Chapter 2) by describing forest stands in terms of their interaction with suspended atmospheric particulate material carried along by the wind and susceptible to deposition on foliage. We introduce foliage simulators and their use in measuring the deposit of sprayed pesticide on foliage, the "biological interface" between pest and pesticide.

Throughout the world, there is a need to manage pests in both semi-natural and plantation forests. The sustainable management and control of forest pests depends on the development of Integrated Pest Management (IPM) programmes. A central theme of this book is an examination of the ecological context of the major components of IPM and how and when to apply them in the management of forest pests. The book focuses predominantly on insect pests, but many examples relate to fungal pathogens, some of which are vectored by forest insects. While most examples are from temperate regions, the critical analysis of IPM is relevant to forests world-wide. The book is aimed at undergraduate and postgraduate students of applied entomology and ecology, forestry, agro-forestry, conservation biology and environmental sciences. It will also be of value to managers of IPM programmes in agriculture as well as forestry.

This updated manual is designed to provide background and instruction on a broad spectrum of techniques and their use in the evaluation of entomopathogens in the field. The second edition provides updated information and includes two additional chapters and 12 new contributors. The Field Manual will provide researchers and IPM practitioners with techniques and practical guidance for the study and optimal use of MCAs in a variety of settings.

During recent decades, millions of tonnes of man-made chemicals have been produced and released into the environment, with very little safety testing. Many of these chemical substances have been found to interfere with the endocrine system and modulate its function. This book not only overviews the effects of endocrine/disrupting substances on human health, but also addresses the regulatory problems from the point of view of international organisations, including the WHO, the EU, and the European Chlorine Industry. This volume contains the proceedings of a workshop held at the International Hippocrates Foundation on Kos Island, Greece, in September 1999. The workshop was part of the activities of the ASPIS project, which aims at raising awareness of environmental health impacts among multidisciplinary groups. The contributions to this volume are the result of the interaction of participants at the workshop. As such, it addresses the issue of endocrine disrupters from many different points of view and allows the subject to be approached by a multidisciplinary readership, including: decision makers, medical doctors, environmental experts, post/and undergraduate students, lawyers, engineers, and journalists.
