- From January 2018 through March 2018, 425,000 or 16% of colonies were lost at operations with five or more colonies.
- The number of colonies lost from April through June 2018 was 270,000, or 10%.
- From October through December 2017, 15% of colonies, or 425,000 were lost, which was the highest of any quarter in 2017.

- There was a 15% increase from a year earlier in colonies lost with Colony Collapse Disorder symptoms from January through March 2018, with 77.8 thousand colonies lost. Colonies lost with Colony Collapse Disorder meet the following criteria: Little to no buildup of dead bees in the hive or at the hive entrance, rapid loss of adult honey bee population despite the presenece of queen, capped brood and food reserves and absence or delayed robbing of the food reserves and the loss is not attributable to varroa or nosema loads.
- Varroa mites were the No. 1 stressor for operations with five or more colonies. From January through March 2018, 40.8% of colonies were reported to be affected by varroa mites and from April through June 2018, 53.4% were affected.
