Western Corn Rootworm, "Diabrotica virgifera virgifera LeConte," has been a major economic pest of maize in the Americas for many years. However, since the early 1990s, it has become an increasing threat to crops in Europe and is expected to spread to all maize growing areas of the continent. This book provides a comprehensive review of current knowledge of the biology and ecology of this insect pest and how it might be managed in order to limit its damage as it spreads into new agroecological areas. Cultural, biotechnical and biological control measures are addressed, as are ecological baseline data such as population dynamics, economic thresholds and aspects of its behavior. The book also examines the potential of plant protection techniques currently used in North America to be applied in Europe.

This book provides an invaluable review of the current methodologies used for assessing the environmental impacts of invertebrate biological agents used to control pests in agriculture and forestry. It explores methods to evaluate post-release effects and the environmental impact of dispersal, displacement and establishment of invertebrate biological control agents. It covers methodology on screening for contaminants, the use of molecular methods for species identification and the determination of interbreeding. The book also discusses the use and application of information on zoogeographical zones, statistical methods and risk-benefit analysis. It gives practical advice on how to perform science-based risk assessments and on how to use new technology and information.
