Paperback. Zustand: New. Print on Demand. For over two decades, the Apple Maggot has plagued Southern Ontario apple crops, sometimes causing complete loss in affected orchards. From the Ottawa River to Lake Huron, and as far west as the Detroit River, infestations remain, although most orchards are unaffected. The pest is at its worst in popular apple varieties, such as Early Harvest and Snow, rendering them inedible and unsuitable for canning. This book, written by an entomologist and an entomological researcher, describes the maggot's life cycle, reproductive habits, and the characteristics of its various life stages. Their research led to the development of an effective spray treatment to control the maggots, saving countless future harvests.
