{{Main|List of diseases of the honey bee}}
The common agents of disease that affect adult honey bees include fungi, bacteria, [[protozoa]], viruses, parasites and poisons. The gross symptoms displayed by affected adult bees are very similar, whatever the cause, making it difficult to ascertain the causes without microscopic identification of microorganisms or chemical analysis of poisons.<ref name="Grout">{{cite book|title=The hive and the honey bee: a new book on beekeeping which continues the tradition of "Langstroth on the hive and the honeybee"|editor=Grout, Roy A.|publisher=Dadant and Sons.|year=1949|page=607|chapter=Diseases of Adult bees|chapter-url=https://books.google.com/books?id=K84OAAAAQAAJ&q=diseases%20of%20bees&pg=PA607|access-date=21 June 2013|archive-date=26 July 2020|archive-url=https://web.archive.org/web/20200726063826/https://books.google.com/books?id=K84OAAAAQAAJ&pg=PA607&q=diseases%20of%20bees|url-status=live}}</ref> Since 2006, colony losses from [[colony collapse disorder]] (CCD) have been increasing across the world, although the causes of the syndrome are unknown.<ref>{{cite book|last=Johnson|first=Renee|title= Honey Bee Colony Collapse Disorder|year=2010}}</ref><ref>{{cite news|url=https://science.time.com/2013/05/07/beepocalypse-redux-honey-bees-are-still-dying-and-we-still-dont-know-why/|title=Beepocalypse Redux: Honeybees Are Still Dying – and We Still Don't Know Why|last=Walsh|first=Bryan|date=7 May 2013|work=Time Science and Space|publisher=Time Inc|access-date=21 June 2013|archive-date=7 June 2013|archive-url=https://web.archive.org/web/20130607031746/http://science.time.com/2013/05/07/beepocalypse-redux-honey-bees-are-still-dying-and-we-still-dont-know-why/|url-status=live}}</ref> In the U.S., commercial beekeepers have been increasing the number of hives to deal with [[Pollination#Economics of pollination|higher rates of attrition]].<ref>{{Cite news|title = Call off the bee-pocalypse: U.S. honeybee colonies hit a 20-year high|url = https://www.washingtonpost.com/news/wonk/wp/2015/07/23/call-off-the-bee-pocalypse-u-s-honeybee-colonies-hit-a-20-year-high/|newspaper = The Washington Post|date = 2015-07-23|access-date = 2015-12-01|issn = 0190-8286|language = en-US|first = Christopher|last = Ingraham|archive-date = 2015-11-30|archive-url = https://web.archive.org/web/20151130082605/https://www.washingtonpost.com/news/wonk/wp/2015/07/23/call-off-the-bee-pocalypse-u-s-honeybee-colonies-hit-a-20-year-high/|url-status = live}}</ref>
