The first edition of the book has now been fully revised and updated. The second edition contains more than 60 new pests and almost 90 new colour photographs.
Pests of Ornamental Trees, Shrubs and Flowers opens with a review of the main features of insects, mites and other major pest groups. The principles of pest control of ornamental plants are discussed, followed by sections on the various pests. Each major order and family is considered, with details of status, host range, world distribution, diagnostic features and biology. Characteristic damage caused is also described.
The book aims to provide a unique source of permanent reference for all involved in the biology and control of the pests of ornamental crops, including professionals, scientists and students in agriculture, horticulture and entomology, and amateur gardeners.
