Polyandry is the case in social insects, such as the honey bee (Apis mellifera) in which a female mates with many males. Many studies revealed polyandry give significant benefits to the growth and health of honey bee colonies. I hypothesized that cohorts of worker bees from a polyandrous mother will exhibit lower rates of mortality than cohorts from a less polyandrous mother. The objective of this study was to examine the effect of polyandry on bee mortality and to find out whether there is interaction between the level of polyandry and parasitic mite (Varroa destructor). My study found no significant effects of polyandry, mites, nor their interactions on survival time of bees. Similarly, there was no significant effect of polyandry on survival time of mites. These results are incongruent with other studies that indicate benefits of polyandry. I offer and discuss four explanations for these findings.

This book summarizes the current progress of bee researchers investigating the status of honey bees and possible reasons for their decline, providing a basis for establishing management methods that maintain colony health. Integrating discussion of Colony Collapse Disorder, the chapters provide information on the new microsporidian Nosema ceranae pathogens, the current status of the parasitic bee mites, updates on bee viruses, and the effects these problems are having on our important bee pollinators. The text also presents methods for diagnosing diseases and includes color illustrations and tables.

Introduces readers to key case studies that illustrate how theory and data can be integrated to understand wildlife disease ecology.

An essential guide to the health care of honey bees Honey Bee Medicine for the Veterinary Practitioner offers an authoritative guide to honey bee health and hive management. Designed for veterinarians and other professionals, the book presents information useful for answering commonly asked questions and for facilitating hive examinations. The book covers a wide range of topics including basic husbandry, equipment and safety, anatomy, genetics, the diagnosis and management of disease. It also includes up to date information on Varroa and other bee pests, introduces honey bee pharmacology and toxicology, and addresses native bee ecology. This new resource: Offers a guide to veterinary care of honey bees Provides information on basic husbandry, examination techniques, nutrition, and more Discusses how to successfully handle questions and 'hive calls' Includes helpful photographs, line drawings, tables, and graphs Written for veterinary practitioners, veterinary students, veterinary technicians, scientists, and apiarists, Honey Bee Medicine for the Veterinary Practitioner is a comprehensive and practical book on honey bee health.

The existing theories on the evolution of senescence assume that senescence is inevitable in all organisms. However, recent studies have shown that this is not necessarily true. A better understanding of senescence and its underlying mechanisms could have far-reaching consequences for conservation and eco-evolutionary research. This book is the first to offer interdisciplinary perspectives on the evolution of senescence in many species, setting the stage for further developments. It brings together new insights from a wide range of scientific fields and cutting-edge research done on a multitude of different animals (including humans), plants and microbes, giving the reader a complete overview of recent developments and of the controversies currently surrounding the topic. Written by specialists from a variety of disciplines, this book is a valuable source of information for students and researchers interested in ageing and life history traits and populations.
