Fig. 6. Overall effects of temporary exposures to pyriproxyfen on reproduction in ten-d old Daphnia magna:
Female Daphnia magna that were ten-d old were exposed to 155 pM pyriproxyfen for 2, 4, 8, or 12 d and reproduction monitored for 16 d. Data on the number and sex of the neonates produced are shown as mean ± SEM. (a) Indicates a significant difference in the total number of neonates produced, (b) indicates a significant difference in the number of male neonates produced, and (c) indicates a significant difference in the total number of female neonates produced compared to untreated (UT) Daphnia magna. Statistical difference were analyzed by ANOVA followed by Dunnett's multiple comparison test and an (*) indicates p < 0.05 and (**) indicates p < 0.01 (n = 10).
