Bees, both commercially managed honey bees and wild bees, play an important role in global food production. In the United States alone, the value of insect pollination to U.S. agricultural production is estimated at $16 billion annually, of which about three-fourths is attributable to honey bees. Worldwide, the contribution of bees and other insects to global crop production for human food is valued at about $190 billion. Given the importance of bees and other types of pollinators to food production, many have expressed concern about whether a pollinator crisis has been occurring in recent decades. Worldwide reports indicate that populations of both managed honey bees and native bees have been declining, with colony losses in some cases described as severe or unusual. In Europe, managed honey bee colony numbers have been declining since the mid-1960s, and individual beekeepers have reported unusual weakening and mortality in colonies, particularly during the period spanning winter through spring. According to the United Nations, many insect pollinator species may be becoming rarer, causing some to question whether this is a sign of an overall global biodiversity decline. This book examines selected U.S. Department of Agriculture (USDA) agencies bee-related monitoring, research and outreach, as well as conservation efforts, and The Environmental Protection Agency's (EPA) efforts to protect bees through its regulation of pesticides.

The cockroach is truly an evolutionary wonder. This definitive volume provides a complete overview of suborder Blattaria, highlighting the diversity of these amazing insects in their natural environments. Beginning with a foreword by Edward O. Wilson, the book explores the fascinating natural history and behavior of cockroaches, describing their various colors, sizes, and shapes, as well as how they move on land, in water, and through the air. In addition to habitat use, diet, reproduction, and behavior, Cockroaches covers aspects of cockroach biology, such as the relationship between cockroaches and microbes, termites as social cockroaches, and the ecological impact of the suborder. With over 100 illustrations, an expanded glossary, and an invaluable set of references, this work is destined to become the classic book on the Blattaria. Students and research entomologists can mine each chapter for new ideas, new perspectives, and new directions for future study.

"Stream Ecosystems in a Changing Environment" synthesizes current understanding in stream ecosystem ecology, emphasizing nutrient cycling and carbon dynamics, and provides a forward-looking perspective regarding the response of stream ecosystems to environmental change. Stream ecosystem ecology has undergone major advances in the past decade following a series of high-profile and innovative research initiatives focusing on nutrient cycling and metabolism. Each chapter includes a section focusing on anticipated and ongoing dynamics in stream ecosystems in a changing environment, and hypotheses regarding controls on stream ecosystem functioning. These innovative sections provide a bridge between papers published in peer-reviewed scientific journals, and researchers development of new ideas areas of study.
Provides a synthesis of the latest findings on stream ecosystems ecology in one volumeIncludes thought exercises and discussion activities throughout, providing valuable tools for learningOffers conceptual models and hypotheses to stimulate conversation and serve to advance research"

A "New York Times "Notable Book
A stunningly original exploration of the ties that bind us to the beautiful, ancient, astoundingly accomplished, largely unknown, and unfathomably different species with whom we share the world.
For as long as humans have existed, insects have been our constant companions. Yet we hardly know them, not even the ones we're closest to: those that eat our food, share our beds, and live in our homes. Organizing his book alphabetically, Hugh Raffles weaves together brief vignettes, meditations, and extended essays, taking the reader on a mesmerizing exploration of history and science, anthropology and travel, economics, philosophy, and popular culture. "Insectopedia "shows us how insects have triggered our obsessions, stirred our passions, and beguiled our imaginations.

This is a reproduction of a highly popular book originally published by the U.S. Bureau of Entomology. The purpose of this book is to provide the reader with a detailed description of insects and much of the material is based in part from article written in the early part of the last century by the Smithsonian Institution. Readers will find the detail a delight to read.

Bees, both commercially managed honey bees and wild bees, play an important role in global food production. In the United States alone, the value of insect pollination to U.S. agricultural production is estimated at $16 billion annually, of which about three-fourths is attributable to honey bees. Worldwide, the contribution of bees and other insects to global crop production for human food is valued at about $190 billion. Given the importance of honey bees and other bee species to food production, many have expressed concern about whether a pollinator crisis has been occurring in recent decades. Over the past few decades there has been heightened concern about the plight of honey bees as well as other bee and pollinator species. This book provides a background on bee health. It also discusses the role of pesticides in bee health and provides guidance to risk assessors for evaluating the potential risk of pesticides to bees, particularly honey bees.

Forests possess many components and processes that provide an array of ecosystem goods and services: timber, energy and water savings, pollution reduction, livestock forage, habitat for plants and animals, recreation opportunities, aesthetic landscapes, and biodiversity that enhance people's quality of life. Forest resources also support local and regional economies through jobs and income generated from forestry, agriculture, tourism, and locational decisions of businesses, retirees, and others. The capability of a forest to provide these and many other ecosystem services and to maintain the quality of those ecosystem services depends on its health. A healthy forest is an essential component of a healthy ecosystem -- a natural system that is capable of self-renewal, resilient in its response to disturbances (such as pest, fire, and other non-human and human-caused disturbances), and able to sustain the integrity of the natural and cultural benefits derived from it. This book updates the literature review and synthesis of economic valuation studies on the impacts of forest insect pests by Rosenberger and Smith. This book also discusses the concept of ecosystem services; identifies key elements of each study; examines areas of future research; and includes appendices that further explain non-market valuation methods, a narrative of each study, and tables that summarise each study.

Beetle species belonging to the coleopteran families Bruchidae, Curculionidae, Laemophoeidae, Silvanidae and Tenebrionidae, as well as beetle-like insects from the psocopteran family Liposcelidae, are responsible for serious damages to agricultural products and resources. These beetles can be primary and/or secondary pests, feeding on integral and healthy grains or attacking those already damaged. The affected grains lose weight and germination power, have nutritive value and vigor decreased, as well as have the hygiene and sanity conditions impaired. This book examines the biodiversity, ecology and role in the environment of beetles.
