Healthy Colony Checklist

Simplifying Inspections to Maximize Results

Background

Apiculture and the global bee population have seen an ever increasing variety of threats over the past 10 years. Although current bee populations in the US have recovered following several years of significant colony losses, the annual losses continue to be above a sustainable level. Significant resources are required for restoring populations, especially from commercial beekeepers. Though it is widely debated, causes of the colony losses may include, but are not limited to: pathogens, varroa mites, management practices that fail to adapt to changing conditions, irresponsible chemical use in the hive and its surrounding environment, genetically modified crops, and changes in global temperature (Ellis, 2007). 

Ever since the unusual conditions of collapsing hives during the winter of 2006, beekeepers and researchers alike have been searching for answers and a better understanding of the factors affecting honey bee mortality. 

The Significance 

Though questions remain and unusual occurrences continue to surface, research and experience both support the notion that a measurable reduction in colony losses can be achieved through management practices that are within the control of the beekeeper. A recent study from 2014­-2015 by the Bee Informed Partnership (BIP), which collects survey data and correlates for annual losses, found summer colony losses eclipsed winter losses for commercial beekeepers, which disagrees with the usual trend of loss (Steinhauer, et al., 2015). 

BIP looks for correlations between management practices and colony loss and has found significant differences in losses for several common management practices, such as the use of varroa control products. 

Below is a summary of total overwintering colony losses in the United States across eleven years of conducting the winter loss survey and across six years of conducting the summer annual loss survey. (BeeInformed.org, 2017)




The Opportunity 

In addition to the issue of declining bee populations, beekeepers and growers of pollinated crops struggle to know the best courses of action to optimize productivity for their bees and crops. Beekeepers and pollination dependent farmers need the knowledge to better manage their colonies and crops to optimize both the economic return by understanding the true cost of beekeeping and the best management practices to better understand the efficacy and impact of various management practices. 

Simplifying Inspections to Maximize Results

"To efficiently and effectively protect and improve colony health, it is now essential to monitor colonies more frequently, even as often as weekly. A method for weekly colony assessments needs to be easy to use, fast, thorough, and yield observations that are meaningful and easy to interpret for practical management decision ­making by apiarists, apiculturists, and apiologists." (Rogers, 2017)

Rogers suggests that the three questions you need answered by the end of a quick colony inspection, are:

1. Is the colony healthy?
2. If not, why?
3. What needs to be done to fix the problem?

Expanding on this simple high level description which captures the basics of a healthy colony, Rogers (2017) details six major indicators or inspection items that largely describe the present state oa hive, which he coined as the "Healthy Colony Checklist". 

The framework proposed by Rogers in the Healthy Colony Checklist provides the infrastructure for a standardized set of guidelines for beekeepers to follow when inspecting hives.
