Article Synopsis
- Recent research contradicts earlier beliefs that glyphosate-based products like Roundup Transorb R® (RT) are safe for bees, showing they can be toxic and increase mortality or cause sublethal effects.
- The study evaluated the toxicity of RT on Africanized honey bees through both acute and chronic exposure experiments, focusing on impacts on mortality, flight capacity, and midgut tissue damage.
- Findings indicate that chronic oral exposure can lead to higher mortality rates and damage to the midgut, while acute exposure negatively affected the bees' walking ability, suggesting significant harm from RT on A. mellifera.
Bees are fundamental insects in agroecosystems, mainly due to pollination. However, its decline has been observed in recent years, and the contamination by pesticides is suspected to be responsible. This relationship is the objective of our research, which is the first scientometric study on this subject.

Consequently, the objective of this work was to evaluate the possible effects of commercial formulations of Bt products, Dipel and Xentari, on the survival and behavior of Africanized honey bees (Apis mellifera). Bioassays were performed on foragers and newly emerged (24-h-old) bees that received the products mixed in the food.
