Greater use of biological control utilizing natural predation, parasitism or other natural mechanisms, is an environmentally friendly alternative to chemical pesticides, which are becoming less readily available due to increasing resistance problems and the prohibition of some substances. This book addresses the challenges of insufficient information and imperfectly understood regulatory processes involved in biological alternatives through an interdisciplinary approach providing an internationally comparative analysis on the registration of biopesticides and the best way forward. An essential read for researchers, students and professionals in political and biological sciences.
