OverviewBees, 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.
