Book Description
Soybean Glycine max (L) Merrill, was first cultivated in china.Soybean is an unique crop with high nutritional value, providing 40 per cent protein and 20 per cent edible oil besides minerals and vitamins.The soybean is a luxuriant crop, soft and succulent foliage attracts many insects and provides unlimited source of food, space and shelter. In Sindh province of Pakistan the soybean is cultivated on marginal scale (44 hectare) and production 45 M.t), however, the crop have use economic importance.About 380 species of insects have been reported on soybean crop from many parts of the world.About 65 insect species have been reported to attack soybean from cotyledon to harvesting stage.The sucking pests viz. Bemisia tabaci (Genn) and Thrips palmi (Karny) cause economic damage. Insect pest complex in soybean cause yield loss up to 24%.The jassid Amrasca devastans (Dist.) is serious pest of soybean, injury to plants is due to the loss of sap and probably also due to the injected toxins.The present study was carried out to assess the relative performance of soybean cultivars against sucking insect pests.

Book Description
Sucking pests are most notorious group of pests for agricultural crops. Unlike most pests with chewing mouth parts, sucking pests cause more severe damage to the crops and are complex to get identified until advanced stages of infection. Not only is this late detection detrimental to their effective control, sucking pests also often cause fungal growth and virus transmission. The book emphasizes on sucking pests of most major crops of India. It aims to reflect Indian scenario before the international readership. This book complies comprehensive information on sucking pests of crops and brings the attention of the readers to this multiple damage causing insect complex. The chapters are contributed by highly experienced Indigenous experts from Universities & ICAR institutes, and book collates useful content for students and young researchers in plant pathology, entomology and agriculture.

Book Description
Bemisia tabaci (Gennedius) has distinguished itself from the more than 1,000 whitefly species in the world by its adaptability, persistence and potential to damage a wide range of agricultural and horticultural crops in all six of the world’s inhabited continents. B. tabaci inflicts plant damage through direct feeding, inducement of plant disorders, vectoring of plant viruses and excretion of honeydew. This book collates multiple aspects of the pest ranging from basic to applied science and molecular to landscape levels of investigation. Experts in multiple disciplines provide broad, but detailed summaries and discussion of taxonomy, genetics, anatomy, morphology, physiology, behavior, ecology, symbiotic relationships, virus vector associations and various tactics for integrated management of this pest insect. The book is focused primarily on progress during the last 10-15 years and is directed at workers in the field as well as the informed professional who may not necessarily specialize in whitefly research. The book is unique in providing broad coverage in relatively few chapters by recognized experts that highlight the state-of-the-art in our understanding of this fascinating but troublesome cosmopolitan pest.

Book Description
Insects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and gen eral nature of insects present special problems to the student of entomology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the mil ligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques fmd their way into the classroom when the problems involved have been suffici ently ironed out to permit students to master the manipulations in a few labo ratory periods. Many specialized techniques are confined to one specific research laboratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomological problems, and (3) to describe experiments which might be applicable for use in biology laboratory courses.

Book Description
The earliest land-plants evolved around 450 million years ago from aquatic plants devoid of vascular systems. The diversification of flowering plants (angiosperms) during the Cretaceous period is associated with speciation in insects. Early insect herbivores were mandibulate, but the evolution of vascular plants led to the co-evolution of other forms of herbivory, such as leaf feeding, sap-sucking, leaf mining, tissue borer, gall forming and nectar-feeding. Plant defense against biotic stress is an adaptive evolution by plants to increase their fitness. Plants use a variety of strategies to defend against damage caused by herbivores. Plant defense mechanisms are either inbuilt or induced. Inbuilt mechanisms are always present within the plant, while induced defenses are produced or mobilized to the site where a plant is injured. Induced defense mechanisms include morphological, physiological changes and production of secondary metabolites. Host plant resistance (HPR) is one of the eco-friendly methods of pest management. It protects the crop by making it less suitable or tolerant to the pest. While books on theoretical aspects of HPR are available, an exclusive book on the practical aspects is lacking. There is a wide gap between the theory and the experimental procedures required for conducting studies on plant resistance for the post graduate students and young researchers. A dire need for a book on practical aspects was strongly felt. Initially a practical manual was prepared which eventually evolved into the present book. We hope this book provides information on major aspects of screening crop germplasm, sampling techniques, genetic and biochemical basis of HPR, behavioural studies on pheromone and plant volatiles, and some of the recent approaches in HPR. Further, the references provide the scientific articles and books as additional information to readers and workers alike.

Book Description
This book presents an overview of the Pentatomidae species, covering their biology, phylogeny and reproductive behavior, main plants used in their diet and their nutritional exigencies, predatory stinkbugs, interactions between herbivores-plants and natural enemies, use of pheromone for monitoring phytophagous populations, and chemical and vibrational communication signals. It also presents possible technologies to be applied in field crops for pest management that could be developed as the basis of the interplay of stink bug communication signals.
