Values of the log-rank statistic for testing homogeneity of survival distribution of MCB when larvae were reared on stems of plants infested with MCB larvae nine days (9d) or 48 hours (48h) before and on untreated (control) plants. Positive values of the log-rank statistic indicate that the number of dead larvae is over the number expected under the null hypotheses of equivalent survival distributions.

^a Log-rank statistics followed by the same latter in the same column mean that survival curves of the different treatment within the same genotype were homogeneous (p < 0.05). The percentage shown between brackets is the mortality percentage.

^b Log-rank statistics followed by the same latter in the same column mean that survival curves were homogeneous between genotypes under the same treatment (p < 0.05).
