This book brings out the world record of various predatory insects and their role in pestiferous insect management in a safer manner. The main focus of the book is to address the ecological and environmentally safe methods of economically important pests of various crops. The utilization of various types of chemical pesticides for our crop protection and food production leads to environmental concerns and health hazards to plants and animals. This book mainly focuses on the distribution and diversity of various predatory insects in different crops. It also sellout the bionomics, biological control potential at a laboratory, controlled fields and natural conditions. Moreover, mass production technology and environmental safety aspects are also highlighted in various chapters. This book is of interest and useful to undergraduates, post-graduates, research scholars and doctoral candidates, extension workers, and agricultural professionals, and also a valuable source of reference to the relevant researchers and students in the region.
