While in much of the world veterinarians have had a decades' long interaction with apiarists, veterinarians in the United States officially joined the honey bee's medical team as a result of the implementation of the 2017 US Food and Drug Administration regulations on the use of medically important antibiotics in livestock. Honey bees were officially defined as food‐producing livestock in those regulations, putting their medical care into the hands of veterinarians. Writing Veterinary Feed Directives and prescriptions, however, should not be our profession's sole offering to honey bee medicine. Our expertise in herd health management will be an asset to the honey bee industry.
Antibiotic resistance has been documented in honey bees and we now know that there can be harmful effects on the honey bee microbiome. There is an increased effort to breed honey bees for hygienic behaviors to develop and enhance natural resistance.
Our Challenge
Just as you don't have to own pigs to be a swine veterinarian, you don't have to be a beekeeper to treat bee colonies. But you do have to know the biology, physiology, and behavior of these magnificent animals in order to forge a Veterinary Client Patient Relationship (VCPR) and feel confident in your handling, diagnosis, and treatment of this species, Apis mellifera, new to our profession.
All the authors in this book recommend experience beyond “book learning” – so join a local bee club, help a beekeeper in the field, or start a few hives of your own.
Learn about the types of beekeepers you may be working with; backyard hobbyists with a few hives, sideliners (whose apiary is a secondary source of income) and commercial beekeepers with many hundreds, or thousands, of hives. Sideliners are nothing new to veterinary medicine as most of our cow‐calf and small ruminant clients have another primary source of income.
As with any other animal we work with, we need to know how to safely handle and manage bees. Will you get stung? Yes, you will. Know your response to bee venom in advance. Know the tools, equipment, and safety precautions you will be taking.
Once you have read the chapters on hive inspections and feel comfortable in a bee suit with insects flying all around you, quietly inspect the bee yard and hives. Observe the macro‐environment for food sources and the activity around the hives. When you are ready to do an internal inspection, look for the different caste members, brood, and food. Get to know normal smells, sounds, and patterns. And don't be frustrated if you can't find the queen – that takes lots of practice!
In the first few chapters, you will learn about honey bees in nature, their arboreal homes, and behavior in the wild. It has been this unique eusocial behavior, division of labor, and adaptations that have allowed them to survive for many millennia. Proceed to the chapters on anatomy, physiology, behavior, colony organization, brood rearing, queen rearing, and swarming.
Bees, just like any other animal, get sick from a variety of diseases – bacterial, viral, fungal, and idiopathic. We provide specific chapters on these varied honey bee pathogens, including Colony Collapse Disorder (CCD). This disease syndrome, although not a major cause of bee mortality anymore, brought vital attention to the cause of global bee deaths, along with much needed research funding adding new knowledge on honey bee health and management.
Nutrition is a determining factor in honey bee colony health. The value and stability of an adequate food supply determine the homeostasis of the hive required for colony survival. Morphological changes within the caste members, be it queen development or forager phenotypes, depends on nutrition. We dedicated a large chapter of this text to honey bee nutrition for just these reasons.
Today, the top killer of our honey bees is an introduced pest, the Varroa mite. Many chapters will mention this pest and one is solely devoted to it. It is very difficult to kill an arachnid feeding upon an insect and that brings us to pesticide and pharmaceutical uses. This is an ever‐evolving area of research, looking at the synergistic effects of diseases combined with chemicals in the environment.
As stewards of animal health and participants in One Health, this book is for all veterinarians, veterinary students, technicians, bee research scientists, state/provincial apiarists, and beekeepers. This book is an interdisciplinary collaboration among veterinarians, entomologists, and the beekeeping community. We have forged new relationships to protect honey bees and all pollinators.
For these reasons, there has never been a better or more important time for veterinarians to be involved in honey bee and pollinator health. The honey bee, A. mellifera (and subspecies), may be the most important animal that we veterinarians care for. It would be a different and more difficult world without honey bees and other pollinators. The mutual interdependence of humans, animals, and our environment are exemplified in this One Health challenge.
We end this book with a look to the future, for bee and pollinator research and for the role of veterinarians in this expanding field. Above all, this book intends to teach and amaze you. We should all be humbled by these remarkable animals.

Prologue
Scientists recently discovered the lipid residues of ancient beeswax inside the earthen pottery vessels of Neolithic farmers, which suggests that the origin of domestication of honey bees dates back to the onset of agriculture (Roffet‐Salque et al. 2015). The long association between humans and bees (Figure 1.1), with mankind harnessing honey bees for food, medicine, and spiritual wellness, can be summed up in a single word: beekeeper. In this book, we introduce a new term to the English language: bee doctor. Etymologists, who study word metamorphosis, follow how the use of particular words gradually evolve in our language – e.g. from bee keeper, to bee‐keeper, and finally to beekeeper. Just as the “honey bee” is spelled as two separate words because it is a true bee, we will likewise separate “bee” and “doctor” since bee veterinarians are true doctors in every sense of the word. We work from single bee to whole colony, from individual cell to multicellular organism, and from microenvironment to ecosystem. Given the urgent call for modern Homo sapiens to reverse the anthropogenic impacts on pollinators everywhere, including our sacred Apis mellifera, we propose adoption of “bee doctor” without delay. Humans have been “keeping” bees for thousands of years, so we now have the word “beekeeper.” Only by forging a close connection between human beings and honey bees in all matters relating to their health, do we stand a chance to save one of earth's most industrious species – the one who gives us food, health, and happiness, and
