Effects of glyphosate-based herbicide on royal jelly production of <i>Apis mellifera</i> (Hymenoptera: Apidae) in field conditions

Abstract

To evaluate the effect of Roundup® on royal jelly production, Apis mellifera hives were exposed to food containing sublethal doses of the herbicide. The bioassay was carried out in field conditions with exposed and not exposed hives to Roundup®, three replicates per treatment. The Roundup® diet decreases the amount of royal jelly produced and the number of grafted cells.
