Biological And Biotechnological Control Of Insects Pests

Pest and disease management continues to challenge the agricultural community. The rise in new pest and crop problems juxtaposed with public concern over pesticide use and more stringent environmental regulations creates the need for today's agricultural producers to stay current with new technologies for producing quality crops profitably. Biological and Biotechnological Control of Insect Pests presents an overview of alternative measures to traditional pest management practices, utilizing biological control and biotechnology. The removal of some highly effective broad-spectrum chemicals, caused by concerns over environmental health and public safety, has resulted in the development of alternative, reduced risk crop protection products. These products, less toxic to the environment and easily integrated into biological control systems, target specific life stages or pest species. Predation - recognized as a suitable, long term strategy - effectively suppresses pests in biotechnological control systems. Biological and Biotechnological Control of Insect Pests covers these topics and more. It explores the current approaches in alternative solutions such as: biological control agents, parasites and predators, pathogenic microorganisms, pheromones, botanical insecticides, genetic control, genetic engineering of plants and biocontrol agents, and government regulations for biocontrol agents and recombinant DNA technology. This book will be a useful resource to entomologists, agronomists, horticulturists, and environmental scientists.

Biotechnology has contribute much to the field of insect pest management so far, from side to side development of transgenic plants and other novel ecofriendly products to manage insects. Recognition of the importance and relevance of biotechnological applications in insect control is gaining momentum. There is also improved interest among scientists in developing novel strategies for insect pest management. Realizing the possible benefits and constraints in the use of biotechnology in insect pest management, a national symposium on 'Biotechnology and Insect Pest Management' was organized freshly. Deliberations during the symposium covered various aspects such as insect resistant transgenic crops, microbial pesticides - process and development, botanical pesticides - process and development, hybridization techniques in the production of potential natural enemies, insect and animal vectors of diseases and biosafety concerns, etc. Genetic engineering has been used to enhance the insecticidal efficacy of various strains of Bt by increasing virulence, extending host range, and increasing field stability, and by introducing alternative toxins to facilitate resistance management. Techniques have been developed for production by genetic means of new strains of Bt with new combinations of toxin genes. Crop varieties resistant to insects are far less common than disease-resistant varieties, because plant breeders have traditionally focused more on disease resistance. However, if they are available, resistant varieties can be an effective defense against insect pests. But even when insect-resistant cultivars are not available, some varieties may be less attractive to pest species or may tolerate more damage than others. Plant size, shape, coloration, leaf hair, cuticle thickness, and natural chemicals (attractants and repellents) can all affect pest susceptibility. Farmers can do their own breeding by collecting non-hybrid seed from healthy plants in the field. Plants well adapted to local conditions will be more likely to resist pests. This book throws new light on alternative technologies to control insect pests. Scientists from different institutions from all over world have provided various biotechnology based techniques and other means to manage insect pests.

This book offers a range of environmentally benign molecular mechanisms which are safer alternative strategies for effective insect pest management. In modern era of biotechnology, there has been much advancement in the field of molecular biology, where many more techniques have evolved which can be helpful in the field of pest management too. Plant resistance, development of transgenic plants, and many more techniques are being considered the panacea to pest problems. On the other hand, there are wide spread concerns of the safety of biotechnological interventions with nontarget organisms including humans. While the world stands divided on the ethical issues of these approaches and the many safety concerns, scientists believe that well thought of biotechnological interventions are probably the only safest ways possible for reducing pest attacks on crops. It explores various techniques and aspects related to molecular pathways for crop pest control. This book is a useful resource for postgraduate students and researchers of agriculture sciences, plant pathology and plant physiology. It is also useful for policy planners in agriculture.

The theme of the book is highly relevant to the current emphasis on environment conservation, with focus on native biodiversity conservation in agro-ecosystems. The current impetus being given to organic farming and export oriented agri-hortculture in the country calls for access to relevant scientific knowledge base among the stakeholders. Research on biological pest control is more than a century old in India. Egg parasitoids, which are mainly tiny wasps, led by the family Trichogrammatidae, are the most widely utilized natural enemies for biological control globally. Over thirty countries are using these bioagents to protect over 10 million hectares of agricultural and forestry crops from many important insect pests. The book comprises 18 chapters, which are arranged in continuum, commencing with basic aspects of knowledge and ending in their utilization targets. The chapters cover broadly four areas: bio-diversity and natural occurrence of egg parasitoids, behaviour and adaptation of egg parasitoids, mass production and safe use of egg parasitoids and utilisation of egg parasitoids in different crop ecosystems. Some of the chapters cater to the needs of discipline-wise update on the current R&D scenario-like insect taxonomy, biotechnology, mass-production and quality control of the target organisms - egg-parasitoids, which are useful for laboratory scientists/researchers. There are also chapters devoted to knowledge status and scope for utilization of egg parasitoids in different target crops, which cater to requirements of field entomologists and extensionists for use in their tasks of guiding farmers/local guides. The book is different in approach, method, structure and content and ensures holistic coverage of the topic. The chapters are written by active and experienced workers in different crops and aspects and co-edited by four very experienced experts who have over three decades R&D experience in the subject. All the authors have uniformly focussed on comprehensive literature study and critical identification of knowledge gaps for future R&D, thus the book is novel in outlook, up-to-date in content and comprehensive in coverage of themes. This book will be useful for supplementary reading for MSc Agriculture and PhD Agriculture students, besides MSc/PhD research students in Zoology/Environmental Biology, who are specialising in Entomology. It would also serve as a very useful reference book for researchers worldwide, though focus is also there on Indian work. It addresses the special information needs of students and faculty, besides practitioners and extensionists in the Australasia and Africa regions and thus not limited to the R&D knowledge generated in developed countries.

Integrated Pest Management: Current Concepts and Ecological Perspective presents an overview of alternative measures to traditional pest management practices using biological control and biotechnology. The removal of some highly effective broad-spectrum chemicals, caused by concerns over environmental health and public safety, has resulted in the development of alternative, reduced risk crop protection products. These products, less toxic to the environment and easily integrated into biological control systems, target specific life stages or pest species. Predation — recognized as a suitable, long-term strategy — effectively suppresses pests in biotechnological control systems. Integrated Pest Management covers these topics and more. It explores the current ecological approaches in alternative solutions, such as biological control agents, parasites and predators, pathogenic microorganisms, pheromones and natural products as well as ecological approaches for managing invasive pests, rats, suppression of weeds, safety of pollinators, role of taxonomy and remote sensing in IPM and future projections of IPM.
