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.

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.

Pests cause economic damage to crops and stored products, while vectors are responsible for the transmission of disease-causing agents in human beings and livestock. Although the application of synthetic pesticides in agriculture has given immediate relief, it has also caused well-known side effects, leading to a general consensus among entomologists and agriculturists to shift towards other ecofriendly pest management. Insect natural enemies consisting of predators, parasitoids, and pathogens have attracted the attention of scientists across the globe. These natural enemies exist in agroecosystems and suppress the populations of pests. Parasitoids are farmers’ friends and the most successful group of natural enemies. Highly specialised in their host choice, the female parasitoid searches for a suitable host to lay eggs and larvae in, on or near the hosts. Exploiting this potency of parasitoids may yield successful results in controlling notorious pests in an ecofriendly way. This book covers information on the important biocontrol agents effective in pest suppression. It starts with insect parasitic groups followed by specific groups of parasitoids. It is hoped that the book presents a comprehensive account of beneficial parasitoirds, and will be useful to undergraduate and postgraduate students of Entomology, Biological Control, Plant Protection, Agricultural Zoology, and Zoology, besides those involved in competitive examinations and policy planning. Features: Each chapter has been written by very experienced specialists Every chapter includes Learning Objectives and Points to Remember This book offers comprehensive knowledge of parasitoids and their application in pest management in a rational way

Visitors to tropical forests generally come to see the birds, mammals, and plants. Aside from butterflies, however, insects usually do not make it on the list of things to see. This is a shame. Insects are everywhere, they are often as beautiful as the showiest of birds, and they have a fascinating natural history. With their beautifully illustrated guide to insects and other arthropods, Paul E. Hanson and Kenji Nishida put the focus on readily observable insects that one encounters while strolling through a tropical forest in the Americas. It is a general belief that insects in the tropics are larger and more colorful than insects in temperate regions, but this simply reflects a greater diversity of nearly all types of insects in the tropics. On a single rainforest tree, for example, you will find more species of ant than in all of England. Though written for those who have no prior knowledge of insects, this book should also prove useful to those who study them. In addition to descriptions of the principal insect families, the reader will find a wealth of biological information that serves as an introduction to the natural history of insects and related classes. Sidebars on insect behavior and ecological factors enhance the descriptive accounts. Kenji Nishida’s stunning photographs—many of which show insects in action in their natural settings—add appeal to every page. A final chapter provides a glimpse into the intriguing world of spiders, scorpions, crabs, and other arthropods.
