Of late, frequent application and large scale use of pesticides for control of pests led to the endangerment of agro-ecosystem. Indiscriminate use of insecticides resulted in the destruction of parasitoids and predators of the pests and ultimately led to the resistance of pests to insecticides and insect resurgence. In the light of these problems, considerable research has been devoted to the elucidation of the toxic residues in/on consumable produce. Considering the seriousness insecticidal problems, there is an urgent need for developing effective economically viable and environmentally safe pest management system. Exploitation of bioagents, biogesticides, biointensive integrated pest management and need base use of pesticides have greater role and scope in overall insect pest and disease management. The publication this book is timely and appropriate for the plant protectionists. There are 41 thought provoking chapters on entomology, plant pathology, nematology and weed science written by the scientists who are experts in their subject. The book is an asset for the policy makers, administrators, teachers, research workers and students who may be referring the literature time to time.
