Lab flies have lower microbiome diverity than wild flies

  • Reduced Richness and Diversity: Lab-raised flies exhibit significantly lower richness and diversity of bacteria compared to wild-caught flies.

  • Specific Strains: Laboratory flies have bacterial strains closely related to those from previous studies, with five strains being >99% identical to previously identified cultured isolates of D. melanogaster.

  • Enterococcus, which was previously found to comprise nearly 50% of the lab bacterial microbiome, is virtually absent in current lab samples.

Forward & reverse genetics

Forward genetics: Start the research with an organism (eg. diseased or natural mutant) and then work backward to discover the genetic basis for it.  Reverse genetics, where specific genes are modified or manipulated to study their effects on a phenotype.

Propionic acid promotes larval survival

Propionic acid promotes larval survival (in low-nutrient food i.e. low yeast). Propionic acid is detected by Laravel chemoreceptors Or30a and Or94b. This propionic acid activity works on Dmel, but not on D. suzukii. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5660182/#:~:text=Propionic%20acid%20in%20the%20culture,medium%20(6.5%25%20yeast).
