In all, 1550 species of whiteflies have been identified. The rapid spread of Bemisia tabaci has occurred throughout the globe and it is regarded as the most notorious species. It is a complex species known to contain many biotypes namely, New World (Biotype -A), B-biotype MEAM1 (Biotype-B or Bemisia argentifolii, and MED (Biotype-Q) depending upon the geographical location. The complete information on the bio-ecology of important species along with the feeding mechanism has been presented in this book. The use of modern techniques of identification has added more biotypes considering the variations in host range, species of endosymbionts, virus transmission efficiency, and resistance to pesticides. The resistance and resurgence due to pesticides has been discussed in the monograph. The information on economic thresholds for judicious use of pesticides or release of natural enemies against whiteflies has been quoted in this compilation The pest control methods, namely chemical, cultural measures, biocontrol agents, resistant varieties, and mechanical devices have been elaborated on. Based on the availability of information the integrated model has been suggested to contain the whitefly menace under different situations. Considering the key factors responsible for the outbreak of whiteflies, a sound system of IPM has been formulated. The book also contains the use of semiochemicals and biotechnological tools likely to gain momentum in the future.

Sustainable Management of Arthropod Pests of Tomato provides insight into the proper and appropriate application of pesticides and the integration of alternative pest management methods. The basis of good crop management decisions is a better understanding of the crop ecosystem, including the pests, their natural enemies, and the crop itself. This book provides a global overview of the biology and management of key arthropod pests of tomatoes, including arthropod-vectored diseases. It includes information that places tomatoes in terms of global food production and food security, with each pest chapter including the predators and parasitoids that have specifically been found to have the greatest impact on reducing that particular pest. In-depth coverage of the development of resistance in tomato plants and the biotic and abiotic elicitors of resistance and detailed information about the sustainable management of tomato pests is also presented. - Provides basic biological and management information for arthropod pests of tomato from a global perspective, encompassing all production types (field, protected, organic) - Includes chapters on integrated management of tomato pests and specific aspects of tomato pest management, including within protected structures and in organic production - Presents management systems that have been tested in the real-world by the authors of each chapter - Fully illustrated throughout with line drawings and color plates that illustrate key pest and beneficial arthropods associated with tomato production around the world

Begomoviruses are one of the most interesting plant viruses to study for basic and applied research as they cause huge economic losses to agriculture industries and farmers all over the world. They belong to family Geminiviridae and are emergent plant viral pathogens which cause diseases in various crops in the tropical and subtropical regions. They are transmitted by the whitefly (B. tabaci) and have either one (monopartite DNA-A) or two (bipartite DNA-A and DNA-B) genomic components. DNA-A and DNA-B are of ~2600 - 2800 nucleotides each. A number of serious diseases of cultivated crops of the Fabaceae, Malvaceae, Solanaceae and Cucurbitaceae families are caused by Begomoviruses which are considered as threat to their cultivation in many countries. Accurate diagnosis is important for successful diseases management, since plants infected by Begomovirus do not recover, suffer serious yield losses and act as further sources of inoculum, which is then picked up and spread by their vector whitefly (B. tabaci). Reports of occurrence of new viruses and re-emergence of several known viruses in new niches have become regular event. In such a dynamic system, growth of several crop species relies on an accurate diagnosis, management and better understanding of the biology of the casual virus. This is crucial to evolve appropriate control practices and to prevent the virus infection. Researchers have achieved considerable progress in characterization, detection and management of virus on different crop species in the last decade. This book covers latest information in diagnosis of begomoviruses in the present scenario and explores the new vistas in the field of genomics and proteomics. Chapters in Section 1 illustrates the occurrence, genome organisation, transmission and diagnostics of begomoviruses. It also details the diseases caused by begomoviruses on different crops, detection techniques and management strategies in support of research findings by presentation of data, graphics, figures and tables. Section 2 is a chapterwise collection of occurrence, diversity and status of begomoviruses in Asian Africa counties where the diseases are most prevalent. This book will provide wide opportunity to the readers to have complete information and status of begomovirus in Asia and Africa. This will be useful resource for researchers and extension workers involved in the begomvirus disease diagnosis and molecular biology. Expert detection, accurate diagnosis and timely management play a significant role in keeping plants free from pathogens. In this book expert researchers share their research knowledge and literature which are vital towards the diagnosis of begomoviruses, addressing traditional plant pathology techniques as well as advanced molecular diagnostic approach. The book deals with the economically important crops including fruits, vegetables along with challenges in crop protection against diseases caused by begomovirus. This will be resourceful and handy for researcher, practitioners and also students.

Plant viruses are significant as they affect our food supply and are capable of rapidly spreading to new plant species, so a comprehensive study of plant viruses is important in understanding their pathogenesis and prevention. This book focuses on the plant virus evolution, their molecular classification, epidemics and management. The key features in the book includes genome organization, translation and replication, virus-coded proteinases, structure of virus particles, cell receptors and host range, the RNA polymerase, quasispecies dynamics and virus evolution, and its natural habitats.

Thanks to the application of new technologies such as whole-genome sequencing, analysis of transcriptome and proteome of insect pest to agriculture, great progress has been made in understanding the life style, reproduction, evolution and nuisance to crops caused by insect pests such as aphids, planthoppers, and whiteflies. We believe that time has come to summarize progress and to have a glance over the horizon. In this Book experts in the field discuss novel means to increase the different kinds of resistances of plants to better limit the effects of pest, to understand and disturb the hormonal regulation of embryogenesis, molting, metamorphosis and reproduction, to determine the function of insect genes in diverse processes such as metabolism, interaction with plants, virus transmission, development, and adaptation to a changing environment. The knowledge presented here is discussed with the aim of further improving control strategies of insect pestsman";mso-hansi-theme-font:minor-bidi;mso-bidi-theme-font:minor-bidi; mso-ansi-language:NL;mso-fareast-language:NL;mso-bidi-language:AR-SA">.
