Abstract

Objective: To analyze the importance of the quality of the growth medium as to the development of Drosophila melanogaster grown in the laboratory, in order to assess changes in physical fitness and in the survival and fertility rates of the studied populations, both of the White and wild strains, according to the yeast. provided as a food resource. Method: To do this, different yeasts were used as food resources (Saccharomyces cerevisiae, Dekkera bruxelensis and Meyerozyma caribbica) in the standard medium and in order to evaluate the variables, the RING test and analysis of survival and fertility rates were performed. Results: Through the data, the growth medium with Saccharomyces cerevisiae was that with all analyzed rates were within the expected value and that the individuals were able to complete their life cycle, while the other resources did not obtain the expected values. Conclusion: The efficiency of Saccharomyces cerevisiae for maintenance medium is confirmed, in addition to this fact, with the intriguing result of the other two yeasts, it is necessary to add different evaluation methods so that the results become increasingly robust.
