Suplementary material from Agrochemical synergism imposes higher risk to neotropical bees than to honeybees

Suplementary material containing the raw data of the concentration-mortality bioassays. The pesticide effects on pollinator biodiversity is a global trend that is garnering much concern. Initially, there was significant concern about pesticide-mediated reductions in the number of honey bee pollinators, primarily Apis mellifera in the USA and in some European countries, but those initial concerns have been replaced by a broader concern related to the decline of pollinator bees in general. Here, we evaluated the impact of multiple stressors (e.g., insecticides and fungicides) on Africanized honey bees and stingless bees that are the most important pollinator insects in agriculture landscapes at the Neotropical regions. We demonstrated that the synergistic effects of agrochemicals (e.g., insecticides and fungicides) pose an increased risk to the Neotropical stingless bees Partamona helleri compared to the Africanized A. mellifera, which reinforce the notion that A. mellifera is not a faithful model to assess the safety of agrochemicals when compared with other species of bees and emphasize the limited value of extrapolating results of toxicity bioassays from honey bees to native pollinator species.
