Or47b-neurons are necessary in males for normal copulation and male-mating success. Copulation frequency profiles and copulation frequency at the end of 30 min, in assays where (a,b) Or47b-ablated or control males are allowed to mate with CS females, or (c,d) Or47b-ablated or control females (inverted triangle for ablated and circles for intact) are allowed to mate with CS males. (e) Copulation latency of Or47b-ablated (dark bars) and intact control males (light bars) when assayed in three differently sized arenas. The y-axis represents time (min) taken by flies to initiate copulation (copulation latency). (f) Mating success of Or47b-ablated (dark bars) and intact control males (light bars) in competition to secure mating with CS females. Or and dti code for intact controls Or47b/+ and dti/+, whereas Ordti codes for Or47b-ablated flies (Or47bGAL4/UASdti). All other details same as in figure 1.
