Sulfoximine-based insecticides, such as sulfoxaflor, are of increasing global importance and have been registered for use in 81 countries, offering a potential alternative to neonicotinoid insecticides.Previous studies have demonstrated that sulfoxaflor exposure can have a negative impact on the reproductive output of bumblebee colonies, but the sp...


... In that study, synergism was tested with sulfoxaflor doses ranging from 2.75 to 88 ng/bee combined with a single fluxapyroxad dose (1200 ng/bee) and synergism was observed only at intermediate Our study shows that sulfoxaflor affects feeding behaviour in O. bicornis by increasing (at 20 ppb) and decreasing (at 100 ppb) syrup consumption compared to control bees. This result is in partial agreement with previous studies which found inhibitory effects of sulfoxaflor in bumblebees (Siviter et al., 2019) and honey bees (Barascou et al., 2021;Li et al., 2021). Similar results have been found in A. mellifera (Zhu et al., 2017), B. terrestris (Laycock et al., 2012Thompson et al., 2015) and O. bicornis (Azpiazu et al., 2019) exposed to neonicotinoids. ...
