Fig. 5. Temporal effects of periodic exposure to pyriproxyfen on reproduction in ten-d old Daphnia magna:

Fig. 5

Female Daphnia magna (10-d old) were exposed to 155 pM pyriproxyfen for 2, 4, 8 or 12 d and reproduction quantified to determine the time-dependent effects of pyriproxyfen on the number of male (A) and female neonates (B) produced. Data are shown as mean ± SEM. Statistical differences from the untreated daphnids were determined by ANOVA followed by Tukey's multiple comparison test. An (*) indicates all treated groups are different from the untreated (UT) group (p < 0.001), ($) indicates a significant difference between the groups treated for 2–4 d and the other groups, and (#) indicates a significant difference between the group treated for 12-d and all the other groups (p < 0.001) (n = 10). Colored arrows indicate the age in which pyriproxyfen exposure is withdrawn.
