Juveniles and adults require different sets of sensory neurons for attractive diacetyl chemotaxis. A–E, AWA is required in adults and juveniles for attraction to diacetyl. A, B, Interestingly, AWB and ASK are also required in adults, but not L3, for attraction. C, D, At intermediate levels of diacetyl, AWA and ASK are required in adults for attraction. ASE is also involved in L3 attraction. E, F, At a high level of diacetyl, only AWA is required in adults. By contrast, AWA and ASE play roles in L3 chemotaxis. Averages and SEM are shown in A, C, and E with numbers on each bar representing the number of assays. Data were compared using one-way ANOVA with Bonferroni correction for multiple comparisons (*p < 0.05). B, D, F, Schematics of adult and L3 neurons required for attractive diacetyl behavior.
