Nano-La₂O₃ Induces Honeybee (Apis mellifera) Death and Enriches for Pathogens in Honeybee Gut Bacterial Communities.

ABSTRACT: Honeybees (Apis mellifera) can be exposed via numerous potential pathways to ambient nanoparticles (NPs), including rare earth oxide (REO) NPs that are increasingly used and released into the environment. Gut microorganisms are pivotal in mediating honeybee health, but how REO NPs may affect honeybee health and gut microbiota remains poorly understood. To address this knowledge gap, honeybees were fed pollen and sucrose syrup containing 0, 1, 10, 100, and 1000mgkg^-1 of nano-La₂O₃ for 12days. Nano-La₂O₃ exerted detrimental effects on honeybee physiology, as reflected by dose-dependent adverse effects of nano-La₂O₃ on survival, pollen consumption, and body weight (p<0.05). Nano-La₂O
