Survival curves for the F 1 generation. The six groups examined in the present study and the five groups examined in previous studies [7]-[10] are plotted together. The survival curves were roughly segregated into three clusters of the experimental groups. The concentrations of caesium activity in the ingested host plant leaves are indicated, together with the time period of the experiments. Groups that were examined in the summer of 2012 are indicated by brownish colours with circular symbols. Groups examined in the fall of 2012 are indicated by purplish colours with square symbols. Groups examined in the summer of 2011 in previous studies [7]-[10] are indicated by greenish colours with triangular symbols.
