Life history and control of major parasites and predators of silkworm have been discussed in detail. The principles and methods of pest control have been described with ecological bias. Efforts have made to include cultural, mechanical, legislative, biological and chemical methods of pest control so that student can draw help from them while devising integrated control practices, this book also discusses the general principles underlying chemical pesticides along with a brief history of their development. It lists the main types of insecticides, and herbicides with discussion of their chemical preparation, uses and biochemical mode of action. Some novel methods of pest control viz. use of attractants, repellants chemo-sterilants and herbal methods have been discussed in detail. The adverse impact of the agrochemicals on the ecosystem has been described along with mitigating measures such as biological control. Conservation and augmentation of predators and parasitoids for control of parasites have also been included. The principles, concepts, mechanisms and current practices of biological control of insect pests have been described in detail.
