Appendix

Table 1. Results of Kruskal-Wallis tests and comparisons of ranks to examine significant differences in survival among treatments. C = control (0 fruits), I5 = 5 intact fruits, I10 = 10 intact fruits, C5 = 5 crushed fruits, and C10 = 10 crushed fruits. If p < 0.05, then there were significant differences overall. These differences are shown in ranks as “>” signs.
