Publisher's Synopsis
The field of biological control of weeds continues to expand, offering and ecologically sound and cost-effective method of controlling invasive weed species.;More and more new agents are being assessed and released, while increasing international collaboration has enabled wider use of already successful agents.;In particular there has been a dramatic increase in biological control programs in developing countries and those targeting weeds invasive in natural environments.;The fourth edition of this catalogue provides a comprehensive reference source to all attempts at biological control of weeds undertaken to the end of 1996.;A substantial number of new releases have been made since the publication of the third edition in 1992.;The information in the catalogue is presented in four detailed lists: list A details with exotic vertebrates and fungi that have been released for biological control, and their target weeds; list B includes exotic invertebrates, essentially fish species, utilised to control weeds; list C deals with organisms that have been deliberately manipulated for weed control within their natural ranges; and list D covers organisms that have been released as biological control agents and now occur in countries other than those into which they were released.;Each entry details the target weed, control agent, year of first release, country of origin of agent, status and degree of control, research organisation involved, and key references.;The catalogue format has been modified slightly from earlier editions to improve ease of use. The book provides a means of keeping track of the world situation and should be reference for professionals, research workers and students interested in the biological control of weeds.
