Observation | I have seen fruit flies of the species (D. melanogaster) feeding on fermenting bananas. |
Problem | Why do fruit flies prefer bananas containing yeast? Is their interest focus on yeast concentration? |
Research the problem | D. melanogaster prefer soft bananas due to the production of yeast taking place within the fruit. |
Hypothesis | D. melanogaster will prefer a sample of bananas with yeast to other fruits (apple, and mango) and to a standard media culture |
Null Hypothesis (H0) | With regards to fruit preference of D. melanogaster there will be no differences between bananas with added, standard culture media, and other fruit preference |
Test the Hypothesis- Experimental Design Method & Materials | To test this hypothesis I will set-up (12) 3.785-liter mason jar-like glass containers each containing four water bottle caps of the same size. One bottle cap will serve as the control feed (standard fruit fly media culture) and the remaining three will contain slice of banana, apple, and pineapple respectively. After 55 minutes, the number of flies in each bottle cap will be recorded and then analyzed using Anova statistics (Hardy 2004). |
