Fig. S3.

Differential responses of fifth instar nymphs toward fecal extracts from axenic nymphs inoculated with various bacterial isolates. Fifth instar nymphs (n total) were tested in no-choice olfactometers with sterile water (SW), extracts of control feces (CF), axenic feces (AF), and feces from bacteria-inoculated axenic groups (In-Mix6, In-1, and In-2). The bacterial isolates are listed in Table S4. Responding (%) is the percentage of tested nymphs that were stimulated to orient upwind and shelter on the filter paper. Different letters indicate significant differences among treatments (Tukey’s WSD, P < 0.05).
