Fig. 4. Reproductive output of adult Drosophila melanogaster fed green tea polyphenols during larval stages.
The fertility of emerged offspring from GTP-treated food was determined by measuring the number of eggs, pupae and adults formed from each sex over a 10-day mating period. Female flies exhibited a significant reduction in overall reproductive output including eggs laid (A), pupae formed (B) and emerged offspring (C) (P<0.0001). Male flies showed no difference in fertility by the number of eggs laid (D) or pupae (E) formed (P>0.05) however, an increase in the number of emerged flies was observed (P=0.01) (F). Data are presented as means ± SEM (n=60 per treatment per sex) and analyzed by two-way ANOVA. P >0.05 are not significant.
