*3.1. General Information*

The articles analyzed in this meta-analysis (*n* = 293) were published in 128 different journals, the three most frequent being *Plos One* (13%), *Apidologie* (10%), and the *Journal of Apicultural Research* (6%) (Supplementary Materials, Figure S3). The number of papers published per year increased relatively steadily (Figure 2) from 2010 (24 papers) to 2016 (54 papers). This could be a sign of the scientific community's growing interest in bee health and especially its willingness to investigate the mechanisms leading to abnormal bee mortality.
