Table 1 Effects of Drosophila melanogaster diet containing different Cry proteins on survival and increase in fresh weight of Heliothis virescens. Artificial Heliothis diet containing the same amount of untreated D. melanogaster diet, which was also applied in the respective Cry treatments, served as negative controls. “yes” indicates lower survival or fresh weight of H. virescens in the Cry treatment vs. the control, either for fresh diet or for diet aged for 5 days, based on non-overlapping 95% confidence intervals in both experimental trials, “no” indicates overlapping 95% confidence intervals in both trials, “(yes)” indicates a significant effect in only one of the trials. For Cry1F, only 8 individuals survived in the fresh diet treatment, thus weight increase was not analyzed. Sample size per treatment and trial was 20. For more details see Supplemental Table S5.
