The responses of ab3A neurons vary with sex and maturity. a Sample traces for ab3 sensilla from multiple w 1118 male flies responding to a 0.5-s stimulation (black bars) of water, fresh apple odor, or ethyl butyrate (EB, 10−5 v/v). The red bars indicate the 200-ms quantification window. The larger spikes are the ab3A neurons, and the smaller spikes are the ab3B neurons. b Peak odor-evoked activity of the ab3A neurons of 7- to 14-day-old flies of both sexes (50:50) responding to water, paraffin oil (PO), fresh apple odor, EB (10−5 v/v), or EB (10−4 v/v). Boxplot whiskers indicate minimum and maximum values, one-way analysis of variance (ANOVA), P ≤ 0.001 (***). Replicate numbers for water = 15; paraffin oil = 16; apple = 6; EB 10−5 v/v = 10; EB 10−4 v/v = 9. c Peak odor-evoked responses of ab3A neurons of male (♂) and female (♀) w 1118 flies to ethyl butyrate (EB, 10−5 v/v) recorded 1, 3, and 7 days (1d, 3d, 7d) post-eclosion. The data are presented as means ± standard error, one-way ANOVA, non-significant (ns), P ≤ 0.05 (*), P ≤ 0.001 (***). Replicate numbers for 1d males = 6; 3d males = 7; 7d males = 8; 1d females = 6; 3d females = 6; 7d females = 6
