Changes in Microbiome Confer Multigenerational Host Resistance after Sub-toxic Pesticide Exposure

Abstract

Wang et al. demonstrate low-level toxicity of atrazine in Nasonia wasps. A single, sub-toxic exposure causes changes in the gut microbiota that are transmitted to the next generation. Populations that are exposed every generation become resistant to high-level exposure, with atrazine resistance conferred by metabolic capabilities of at least two rare bacteria.
