Classical biological control of weeds makes use of their natural enemies and is considered a sustainable method for managing invasive and exotic weeds. The approach is particularly interesting for large-scale application where chemical or mechanical means of control would be less feasible due to high costs or negative environmental impacts. This peer-reviewed anthology covers the ecology and distribution of 20 model invasive tropical weed species and presents the successes and failures of biological control programmes using arthropods. The book starts with a useful introductory chapter and concludes with three, slightly redundant, chapters on national and regional biological control programmes. What most of the case studies show is that effective and sustainable biological control with arthropods requires substantial financial and temporal investments, mainly for research. They can nonetheless generate very high economic returns. Particularly impressive cases presented in this book include the control of different cacti and aquatic weeds like water lettuce, water hyacinth, azolla and salvinia in various parts of the tropics. Arthropods are less likely to have significant impact on witchweeds (Striga spp.). The chapter devoted to these species therefore seems a bit out of place in view of the book title. The book is a useful resource for professionals working on biological control of invasive tropical plants as it provides guidelines for techniques and approaches that can serve the introduction of biological weed management in developing countries. The insights in to insect and weed ecology provided by the various case studies will be of interest to both entomologists and weed scientists.
