(A) Preferred tank location of bsx^m1376 adults after addition of cadaverine (grey and on side indicated by +). Behavior was monitored prior to and after cadaverine addition for 5 min periods. bsx^m1376/+ heterozygotes showed a mild increase in aversive behavior only in the first min after its addition [6 min (Wilcoxon signed-rank test, p = 0.0302), n = 15 adults for each group]. (B) Preference index before and after addition of cadaverine averaged over 5 min periods for bsx^m1376/+ [0286 ± 0.077 and –0.0926 ± 0.0812] and bsx^m1376/m1376 adults [–0.0651 ± 0.0494 and 0.0773 ± 0.0561]. Two-way ANOVA reveals a significant effect of odor delivery [F_{(3, 149)} = 5.323, p = 0.0031], group [F_{(14, 60)} = 6.827, p < 0.0001] and interaction [F_{(42, 180)} = 3.128, p < 0.0001]. Post-hoc analysis by Bonferroni’s multiple comparisons. Numbers represent the mean ± SEM. Dashed red lines in A and B denote midpoint of test tank.
