Paperback. Condizione: New. Print on Demand. This book explores the history and life-cycle of two devastating pests that have plagued farmers in Western Canada: the Hessian Fly and the Western Wheat-Stem Sawfly. The book begins by describing the Hessian Fly's introduction to North America in the 18th century and the extensive crop damage it has caused since then. The author then discusses the more recent appearance of the Western Wheat-Stem Sawfly in the prairie provinces and its impact on cereal crops. The book also examines the relationship between climatic conditions and the abundance of these pests, as well as the role of natural enemies and cultural practices in their control. The author provides detailed descriptions of both insects, their life cycles, and the different types of damage they cause to crops. They also offer practical advice on how to identify and control these pests, including crop rotation, stubble burning, and the use of resistant varieties. With its wealth of information and practical advice, this book is an invaluable resource for farmers, agricultural researchers, and anyone interested in the management of these important pests.

Paperback. Condizione: New. Print on Demand. This book explores the Hessian fly and the western wheat sawfly and the challenges they posed for early farmers in the Canadian prairies. The Hessian fly arrived in North America in the 1770s and spread quickly, causing extensive damage to wheat crops. The western wheat sawfly, historically a native herbivore, began to heavily infest cereal crops as they replaced the native flora. The author provides a comprehensive overview of the life cycles, migratory patterns, and natural enemies of these pests, drawing from research done in the early 1900s. Also included is an examination of cultural control methods, such as crop rotation and field sanitation, that were found to effectively mitigate infestations. The book concludes by emphasizing the importance of ongoing research and cooperation among farmers to manage these pests and protect crop yields.
