APHIS Honey Bee Survey Reports

The USDA Animal Plant Health Inspection Service (APHIS) Honey Bee Survey, is a comprehensive examination of colonies through out the US. The National Honey Bee Survey (NHBS) began in 2009 to address the emerging concern about diminishing health in honey bees. This survey takes an epidemiological approach to document honey bee diseases, pests and pathogens. Additionally, this survey monitors for invasive threats to honey bees, including Tropilaelaps clareae, Apis cerana, and Slow Bee Paralysis Virus. For more information about this program, see  beeinformed.org/aphis/ and the USDA APHIS website.

This page dynamically queries the Bee Informed Partnership database, where the APHIS NHBS data is also stored, to bring you results filtered to the calendar year and state where samples were taken. Click on a year and state for additional results. Please note that if you choose 2016 or earlier, the pesticide results shown will be for Bee Bread only. If you choose 2018 or later, the pesticide results will show only Wax. In 2017, we switched from Bee Bread to Wax for residue analysis. In 2017 only, you will get both Bee Bread and Wax results.

Varroa samples are collected as a composite sample from a single apiary.

Nosema samples are collected as a composite sample from a single apiary.

Virus samples are collected as a composite sample from a single apiary. The virus prevalence chart shows the percentage of samples with each virus found to be positive Nationally for all years since 2013 to this year.  The National prevalence uses data since 2013 only, due to improvements made to the molecular techniques used to determine if the virus is present. For data collected previous to 2013, we still show the prevalence of these samples per state and those are still compared to improved (>2013) molecular data.  However, for BQCV, we use any sample in the database since few samples have been analyzed for BQCV since 2013.

Pesticide Samples

The pesticide samples are collected from the wax combs and are a composite sample from a single apiary. However, prior to 2018, bee bread (stored pollen) was used for pesticide samples. During 2017 to present, samples are taken from wax combs. The charts below indicate if their source was from either wax or bee bread.  The n values per pie piece are the total number of pesticides found within the category, which can be greater than the total number of samples because some samples have multiple pesticides in them.

A table and list of all pesticides found and tested for in either wax or bee bread can be found at the following links.
