There are approximately 20,000 bee species in the world and 1,600 species in California. Despite this diversity, honey bees are still arguably the most important managed pollinator, and this brief overview willfocus on issues plaguing this charismatic insect. However, many of the same stressors are certainly affecting other pollinator populations. In agriculture, honey bees are used for pollinating numerous food plants that make our diets more exciting and nutritious, including many fruits, vegetables and nuts, and they are a crucial contributor to healthy ecosystems.
However, beekeepers in the past decade have been reporting annual honey bee colony losses that have reached 45%, which is more than double the acceptable loss deemed by beekeepers.

In the study, published recently in the journal Microbial Ecology, the researchers first gave groups of bees different kinds of pollen. They found that sick bees, and not healthy bees, lived longer when they had access to the pollen that was more nutritious, even though it also increased the number of parasites found in their gut.
Honey bees that consistently fail to respond to obvious social cues share something fundamental with autistic humans, researchers report in a new study. Genes most closely associated with autism spectrum disorders in humans are regulated differently in unresponsive honey bees than in their more responsive nest mates, the study found.
The European honey bee ( Apis mellifera) is known for its importance for honey production. In addition to honey production, A. mellifera is the most commonly used species as a pollinator in the U.S. Honey bees are managed and used to pollinate over 100 crops grown commercially in North America. Although there are many hobbyist beekeepers, commercial beekeepers are responsible for providing the majority of pollination services to growers. Bumble bees ( Bombus), leafcutting bees ( Megachile rotundata), and to a lesser extent alkali bees (Nomia melanderi) and mason bees (Osmia spp) are also managed for use as pollinators in the U.S (National Resource Council of the National Academies 2007) .
Fred Putnam Jr., a beekeeper from Brandon, VT spent March 10, 2017 at the Southern Adirondack Beekeepers Association meeting and shares some of what he learned.
FP: Some notable info. from today's 2018 Southern Adirondack Beekeeper's Association annual seminar in Malta, NY. "The Varroa problem is at epidemic proportions in this country."That said by Scott McArt, Assistant Professor of Pollinator Health at Cornell University. From Samuel Ramsey, Univ. of Maryland: "The number one most important thing that beekeepers can do to ensure the survival of their colonies is to manage the levels of Varroa mites." Mr. Ramsey is coming to our 2018 VBA summer meeting. He is a very engaging speaker with much new knowledge. Don't miss it.
