Book Description
Thrips (fhysanoptera) are very small insects, widespread throughout the world with a preponderance of tropical species, many temperate ones, and even a few living in arctic regions. Of the approximately 5,000 species so far identified, only a few hundred are crop pests, causing serious damage or transmitting diseases to growing crops and harvestable produce in most countries. Their fringed wings confer a natural ability to disperse widely, blown by the wind. Their minute size and cryptic behavior make them difficult to detect either in the field or in fresh vegetation transported during international trade of vegetables, fruit and ornamental flowers. Many species have now spread from their original natural habitats and hosts to favorable new environments where they often reproduce rapidly to develop intense damaging infestations that are costly to control. Over the past decade there have been several spectacular examples of this. The western flower thrips has expanded its range from the North American continent to Europe, Australia and South Africa. Thrips palmi has spread from its presumed origin, the island of Sumatra, to the coast of Florida, and threatens to extend its distribution throughout North and South America. Pear thrips, a known orchard pest of Europe and the western United States and Canada has recently become a major defoliator of hardwood trees in Vermont and the neighboring states. Local outbreaks of other species are also becoming problems in field and glasshouse crops as the effectiveness of insecticides against them decline.

Book Description
The main purpose of this book is to complement the hitherto largely descriptive works on the order Thysanoptera, by presenting thrips as living animals, stressing the behaviour of individuals and populations, their varied and complex relationships with plants, other animals and the physical components of their abundance in undisturbed and in cultivated habitats, and in cultivated economic importance as pests and beneficia. A considerable literature on thrips has accumulated over the last one hundred years. Unifortunately much of this information is fragmentary, scattered through obscure pamphlets, journales and accsesible only with difficulty.

Book Description
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.

Book Description
Insect Pests of Millets: Systematics, Bionomics, and Management focuses on protecting the cultivated cereals that many worldwide populations depend on for food across the semi-arid tropics of the world. Providing coverage of all the major cultivated millets, including sorghum, pearlmillet, finger millet, barnyard millet, prosomillet, little millet, kodomillet, and foxtail millet, this comprehensive book on insect pests is the first of its kind that explores systematics, bionomics, distribution, damage, host range, biology, monitoring techniques, and management options, all accompanied by useful illustrations and color plates. By exploring the novel aspects of Insect-plant relationships, including host signaling orientation, host specialization, pest – host evolutionary relationship, and biogeography of insects and host plants, the book presents the latest ecologically sound and innovative techniques in insect pest management from a general overview of pest management to new biotechnological interventions. - Includes the most comprehensive and relevant aspects of insect systematics, including synonyms, nomenclatural history, and identification characters to quickly guide readers to desired information - Addresses aspects of insect-plant relationships, including host signaling and orientation, host specialization, pest – host evolutionary relationship, and biogeography of insects and host plant - Presents the latest research findings related to the ecological, behavioral, and physiological aspects of millet pests

Book Description
Ecofriendly Pest Management for Food Security explores the broad range of opportunity and challenges afforded by Integrated Pest Management systems. The book focuses on the insect resistance that has developed as a result of pest control chemicals, and how new methods of environmentally complementary pest control can be used to suppress harmful organisms while protecting the soil, plants, and air around them. As the world's population continues its rapid increase, this book addresses the production of cereals, vegetables, fruits, and other foods and their subsequent demand increase. Traditional means of food crop production face proven limitations and increasing research is turning to alternative means of crop growth and protection. - Addresses environmentally focused pest control with specific attention to its role in food security and sustainability. - Includes a range of pest management methods, from natural enemies to biomolecules. - Written by experts with extensive real-world experience.
