"The development of new plant varieties with enhanced chemical defences has kindled increased interest in the study of insect-plant interaction. Changes in the chemical profiles of plants following insect damage results in deterrent or antibiotic effects in insects. Recent research has provided new dimensions to such interactions through an understanding of chemical signals or chemical information channels with emphasis on induced defences and the resultant, communication interplays. This book attempts to unfold an integrated approach to diverse aspects of plant defence systems against insects, very vital for a better understanding of the modus operandi involved in sustained productivity in agricultural systems."--BOOK JACKET.
