Colony Loss Survey 2012 – 2013

A national survey of managed honey bee 2012-2013 annual colony losses in the USA: results from the Bee Informed Partnership Abstract: For the past six years in which overwintering mortality of honey bee colonies has been surveyed in the USA, estimates of colony loss have fluctuated around one-third of the national population. Here we report […]

It’s a Buzzing World – Finding Precise Counts and Pollinaterps

As a junior searching for research experience, I was able to join the vanEngelsdorp Lab this semester to discover an interest in research I never knew I had. From day 1, I was welcomed and taught how the lab worked as well as the various projects that were occurring. Shortly after, I began my own […]

The Pygmy Shrew: A little mammal that is causing big problems in Canadian overwintering colonies

Typically when critter infestations come up into beekeeping conversation these common mammals come to mind: bears, skunks, mice, opossums and raccoons. Just like their size, pygmy shrews often fall under the radar. However, Fletcher Colpitts, Chief Apiary Inspector of New Brunswick, Canada, is working to make information about the pygmy shrew more available. He recently […]

A “House Moment” in a Bee Lab Continued: Making the Connection

Remember our recent report concerning pesticides? I used a chemical reference database to go through the list and see if I could find any that were lipid-soluble. While many pesticides I looked at were not lipid-soluble, the four chemicals implicated in increasing honeybee vulnerability of Nosema infection in the study above are lipid-soluble. The clearest […]

A “House Moment” in a Bee Lab: Background

The Bee Informed Partnership laboratory at University of Maryland, College Park participated in research to test for the presence of a wide range of pesticides in pollen samples of commercial honeybees. We wanted to know what bees were eating, how many pesticides were present in bee food and at what concentrations, and how pesticide use […]
