Fig. 2: Strain differences in sensing other flies, rather than in the generation of signals, mediates group hyperactivity.
From: Chemosensation drives divergent social behavior in Drosophila
A Schematic for testing if fly-specific signals or sensation contributes to group hyperactivity. A test fly (solid blue) is solo-housed or grouped with 9 helper flies that have clipped wings. B, C Dahomey test flies show increased activity when co-housed with either Dahomey (B) or Canton-S (C) helpers. D Dahomey helpers do not elicit hyperactivity in a Canton-S test fly. Average per hr ± s.e.m. is shown for a 3 h test period between ZT 15-18. All test and helper flies were male (N = 10 vials per condition). *, p < 0.05; **, p < 0.01 (Mann-Whitney U test).
