^aAvoidance of benzaldehyde at the concentration used for conditioning (1×, column 2), or a 10-fold dilution (0.1 ×, column 3; n ≥ 7). Although the effect of benzaldehyde dilution was significant (F_{(1, 271)} = 9.075, p < 0.005), ANOVA did not reveal differences among strains at either dilution.

^bAvoidance of octanol as used for conditioning (1 ×, column 4), or a 10-fold dilution (0.1 ×, column 5; n ≥ 7). Significant effects were revealed for odorant dilution (F_{(1, 267)} = 11.624, p < 0.005) and marginally among strains for 0.1 × octanol avoidance (F_{1, 134)} = 3.987, p < 0.05). Subsequent pairwise comparisons revealed differences among all strains and c772/+, c772/+; UAS-btau/+; heterozygotes, which is unlikely to have contributed to defects in associative behaviors (Fig. 4) because the c772 control is normal in that assay.

^cAvoidance of electrified grids kept at 90 V (column 6) or 45 V (column 7; n ≥ 7). Two-way ANOVA revealed significant effects of stimulus strength (F_{1, 262)} = 11.873, p<0.005), but among strains either at 90 or 45 V.

^dOsmotaxis and navigation toward an attractive odor (column 8). There was no statistical difference in attraction toward 0.05% geraniol and entrance into the olfactory traps (n ≥ 12).
