Arthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival. Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth’s biodiversity. Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago. Arthropods are closely associated with living and non-living entities alike, making the ecosystem services they provide crucially important. In order to be effective, plans for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for in situ and ex situ conservation. This two-volume book focuses on capturing the essentials of arthropod inventories, biology, and conservation.Further, it seeks to identify the mechanisms by which arthropod populations can be sustained in terrestrial and aquatic ecosystems, and by means of which certain problematic species be managed without producing harmful environmental side-effects. This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing the diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations. It addresses the contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods from a holistic perspective before addressing conservation issues at large. This book offers a valuable resource for all zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in the conservation of biological resources.

Conogethes is a group of moths distributed in Austral-Asian region from India to New Guinea, the Solomon Islands and Australia.The moths are also found in Hawaii and Great Britain. Conogethes is mostly known for the economic impact of its larvae on agricultural crops. Substantial research has been undertaken in order to understand the biology of these harmful insects and to develop strategies to confine their impact. Research on chemical communication between males and females via sex pheromones is in progress.Recent research has also focused on the acoustic communication of Conogethes. The moths can feed on more than 200 plants in diversified habitats. The borer moths have become major pest on Horticultural , Agricultural,Avenue trees and forest trees. Its a pest of Quarantine importance as it has been found in Exportable commodities. The book contains 22 chapters from a dozen countries. The authors are from China, Vietnam, Australia, Sri Lanka, Malaysia, Norway etc. This is the first book on the pest globally where interesting insights are provided. This is one of the book of its kind on single pest dealing with almost all aspects of its biology and management on cultivated crops.

This contributed volume aims at bringing together all the genetic engineering tools for managing various types of crop pests. The main focus of this book is to explore the application of these tools in pest management. Major pest groups covered in this book are insects, mites and nematodes.The first section covers all major genetic tools and molecular approaches. The second section deals with genetic tools for of beneficial containing three chapters involving honey bees, silkworms and natural enemies. Next section deals with genetic interactions against pests in diverse geographical regions with special focus on Africa, Vietnam and Sri Lanka. Sections four and five addresses diverse aspects as management of pests, genetic behavior, gene expression, plasticity, pathways and interactions and options for mitigation of pests.It serves as a useful resource for professionals in the fields of entomology, agronomy, horticulture, ecology, and environmental sciences, as well as to agricultural producers and plant biotechnologists.

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.

Floricultural crops all over the world are challenged by a number of insect and mite pests. The pest scenario is changing, and with climate change the instances of new pest incidences have become a more common problem. Like other crops, the intensive cultivation of commercial flowers has accentuated pest problems, as farmers tend to use more agricultural chemicals, which, in turn, increase the problems of pesticide resistance, pest resurgence, and residues leading to health hazards. This volume, Advances in Pest Management in Commercial Flowers, looks at the major challenges and improvements in this growing area today. It first provides an informative overview of worldwide pests of important commercial flowers. It explores a number of important issues in this area, such as the role of climate change on insect pests of commercial flowers and the synthetic chemicals and their possible harmful effects on the environment.
