Fruit flies (Drosophila melanogaster) are excellent models for aging research due to their short lifespan and genetic tools. This study details a standard lifespan assay for fruit flies on a sugar/yeast diet.

Area of Science:

  • Gerontology and developmental biology
  • Model organism research

Background:

  • The fruit fly Drosophila melanogaster is a powerful model organism for aging research.
  • Key advantages include well-understood genetics, defined diets, and a short lifespan (median ~80 days).
  • Lifespan is a primary metric for assessing aging in this model.

Purpose of the Study:

  • To describe a standardized lifespan assay protocol for Drosophila melanogaster.
  • To provide a reproducible method for aging studies using fruit flies.

Main Methods:

  • Utilizing Drosophila melanogaster as the model organism.
  • Housing flies on a standard sugar/yeast diet.
  • Implementing a defined lifespan assay protocol.

Main Results:
