This plan is concerned with protecting and improving the health of managed honey bees. The health of bees is concerned with anything that potentially harms honey bees, including bacteria, viruses, arachnids (e.g. mites), insects, fungi and other pathogens, which cause disease or feed on bees, as well as adverse effects caused by other threats, such as undesirable species that prey on colonies, the misuse of pesticides and the impact of climate change.
