ETH mobilizes calcium in oviduct epithelium via octopamine release. a, d Oviducts of OAMB-Gal4/UAS-GCaMP5 females before (a, d) and after 50 μM OA (a’) and 1 μM ETH (d’) treatment (scale bars = 100 μm). b, e Typical kinetics of the calcium responses to OA (b) and ETH (e). c, f Kinetics of oviduct calcium response to OA (c) and ETH (f) pre-incubated in 1 μM of the OA antagonist epinastine (treatment at red arrowheads). g Average latency to peak calcium response after ETH and OA treatment (n = 10) (biological replicates). Error bars represent SEM. **p < 0.01
