Abstract

Green tea polyphenols (GTP) are a specific antioxidant phytochemical found in green tea. Antioxidants are beneficial to health by preventing illnesses and diseases from taking over the body. GTP has been found to have both positive and negative effects in Drosophila melanogaster. Over 34% of GTP consumption comes from green tea (Fukushima et al., 2009). The purpose was to determine if green tea polyphenols have long term positive or negative effects on the foraging behavior, reproduction and mass of Drosophila melanogaster. The higher the concentration of GTP, the poorer nutritional food choices the Drosophila melanogaster would make. Drosophila melanogaster that are exposed to higher dosages would most likely go to the sugar. Also, the higher the concentrations, the lower the mass would be and the lower the fertility. The amount of Drosophila melanogaster they reproduced would decrease. A choice chamber was created giving the Drosophila melanogaster a choice between banana and sugar, all flies in each culture jar were counted for reproduction, and 100 flies were selected at random and massed individually. Two ANOVA tests [F (16.79) =17, p < .001] and [F (12.23) =12, p < .001] showed significance between GTP and mass of flies for both generations. There were drastic differences in reproduction of flies between GTP groups in both generations. Chi squares also showed differences between foraging behavior for both generations depending on GTP concentration. The hypotheses were overall supported.
