Additional information

Since parental survival on day 21 was below 20% for both groups no statistical analyses were performed. Note further that 20% mortality is allowed for background control mortality. Total reproduction and body length on day 21 were tested for normality and for homogeneity of variance and statistically tested using an ANOVA test followed by a mean comparison test (2-Sample t-test, TOXSTAT Release 3.5, 1996). The respective threshold levels of effect (LOEC) and the respective NOECs were determined on basis of these statistics.
