Western Corn Rootworm is a major pest of maize crops in the Americas, and is now invading Europe. There is therefore a great need for current information on the ecology and management of this species in order to limit the damage it may cause as it spreads into new agroecological areas. This book provides a comprehensive review of current knowledge of this insect pest and how it might be controlled. Comparisons are drawn between experiences in the U.S. and how this might be applied in Europe. Biological control measures and the use of natural enemies from their area of origin in Mexico are also addressed, as are topics such as population dynamics and pest behavior.
