Bees of the world : a guide to every family
\"When many people think of bees, they are likely to picture the western domesticated honey bee, insects that live in large, socially complex societies inside a hive with a single queen and thousands of workers. But this familiar bee is just one of more than 20,000 species of bees--and almost none of the others is anything like it. In Bees of the World, Laurence Packer, one of the world's foremost experts on wild bees, celebrates the amazing diversity of bees--from size and appearance to nests and social organization. Providing clear, accurate accounts of the seven bee families, Bees of the World presents all the key information on generic characteristics, habits, and habitat, illustrated with incredible and often rare photographs that show bees in their natural habitats--foraging, nesting, raising their young, and more. The book reveals the secrets of these extraordinary insects as well as their importance in the global ecosystem and the ways humans can help protect them.\"--Publisher's website.

A cuckoo slumber party? Rediscovery of Nomada , with notes on unusual male aggregatory behavior
Despite tremendous global diversity, little is known about Nomada bees. Nomada (Pachynomada) includes 14 species, all within the Nearctic region. Nomada (Pachynomada) asteris is a rare Kansas native that is described from a single female specimen collected in 1908 and 12 male specimens collected in 1949. The discovery of a putatively healthy population of N. asteris on the outskirts of Lawrence, KS, and a second female museum specimen in the collection at the University of Kansas marks 96 years since the female and 77 years since the male have been observed. An interesting observation was made on the aggregatory roosting behavior of male N. asteris, and is documented here for the first time. This observation marks the first formal description of aggregatory behavior of Nomadinae. These results highlight the importance of both observational surveys and museum specimens in the ongoing pursuit of understanding bee biology, behavior, and diversity, and signify a need for more-thorough modern survey efforts.

Buzz : the nature and necessity of bees
From the award-winning author of The Triumph of Seeds and Feathers, a natural and cultural history of the buzzing wee beasties that make the world go round. Bees are like oxygen: ubiquitous, essential, and, for the most part, unseen. While we might overlook them, they lie at the heart of relationships that bind the human and natural worlds. In Buzz, the beloved Thor Hanson takes us on a journey that begins 125 million years ago, when a wasp first dared to feed pollen to its young. From honeybees and bumbles to lesser-known diggers, miners, leafcutters, and masons, bees have long been central to our harvests, our mythologies, and our very existence. They've given us sweetness and light, the beauty of flowers, and as much as a third of the foodstuffs we eat. And, alarmingly, they are at risk of disappearing. As informative and enchanting as the waggle dance of a honeybee, Buzz shows us why all bees are wonders to celebrate and protect. Read this book and you'll never overlook them again.

Why Do Bees Buzz?
Twenty-five thousand species of bees certainly create a loud buzz. Yet silence descended a few years ago when domesticated bee populations plummeted. Bees, in particular honey bees, are critical links in the vibrant chain that brings fruits, vegetables, and nuts to markets and dinner tables across the country. Farmers and scientists on the agricultural frontlines quickly realized the impact of this loss, but many others did not see this devastation.Why Do Bees Buzz?reports on the mysterious \"colony collapse disorder\" that has affected honey bee populations, as well as other captivating topics, such as their complex, highly social lives, and how other species of bees are unique and different from honey bees. Organized in chapters that cover everything from these provocative pollinators' basic biology to the aggressive nature of killer bees, this insightful question and answer guide provides a honeycomb of compelling facts.With clarity and depth, bee biologist Elizabeth Capaldi Evans and coauthor Carol A. Butler examine the lives of honey bees, as well as other species such as orchid bees, bumblebees, and stingless bees. Accessible to readers on every level, and including the latest research and theory for the more sophisticated reader, the authors reveal more than one hundred critical answers to questions about the lives of bees.Concepts about speciation, evolutionary adaptation and pollination, as well as historical details about topics such as Mayan beekeeping and the appearance of bees in rock art, are arranged in easy-to-follow sidebars that highlight the text. Color and black and white photographs and drawings enhance the beauty and usefulness ofWhy Do Bees Buzz?

Neonicotinoid clothianidin adversely affects insect immunity and promotes replication of a viral pathogen in honey bees
Large-scale losses of honey bee colonies represent a poorly understood problem of global importance. Both biotic and abiotic factors are involved in this phenomenon that is often associated with high loads of parasites and pathogens. A stronger impact of pathogens in honey bees exposed to neonicotinoid insecticides has been reported, but the causal link between insecticide exposure and the possible immune alteration of honey bees remains elusive. Here, we demonstrate that the neonicotinoid insecticide clothianidin negatively modulates NF-κB immune signaling in insects and adversely affects honey bee antiviral defenses controlled by this transcription factor. We have identified in insects a negative modulator of NF-κB activation, which is a leucine-rich repeat protein. Exposure to clothianidin, by enhancing the transcription of the gene encoding this inhibitor, reduces immune defenses and promotes the replication of the deformed wing virus in honey bees bearing covert infections. This honey bee immunosuppression is similarly induced by a different neonicotinoid, imidacloprid, but not by the organophosphate chlorpyriphos, which does not affect NF-κB signaling. The occurrence at sublethal doses of this insecticide-induced viral proliferation suggests that the studied neonicotinoids might have a negative effect at the field level. Our experiments uncover a further level of regulation of the immune response in insects and set the stage for studies on neural modulation of immunity in animals. Furthermore, this study has implications for the conservation of bees, as it will contribute to the definition of more appropriate guidelines for testing chronic or sublethal effects of pesticides used in agriculture.
