• Gut microbes were previously suggested to influence mate preference in Drosophila melanogaster. Mate selectivity depended on the microbiota associated with flies after prior generations were maintained on different diets [cornmeal-molasses-yeast versus starch]. Subsequent studies attempted to repeat these findings with contrasting success. We suggest that a nonstandardized, transient microbiota -- and how it is influenced by diet and dietary additives -- might account for the conflicting results. A point of contention between the studies is that a fungicide used in fly media, methylparaben (mp) -- also known as Tegosept or Nipagin M -- might affect bacterial growth and thus microbiota composition. Although Leftwich et al. argued that moderate mp (up to 0.3%) should not alter microbiota, a previous study suggested that high mp levels (~0.5%) can impact microbiota diversity. How mp concentration affects individual, fly-associated microbes on fly media has not been systematically addressed.
