Increased social spacing in loss of function of VMAT males in large chambers. In these experiments, social spacing was performed on groups of 40 flies in large chambers (see text). A: A heterozygous P element insertion in VMAT - L(2)SH0459 - tested both in red eyed (w+;p/+) and orange eyed (w-;p/+) background (both in doted box) shows the same decrease in social space, significantly different from that of the red eyed wild-type background control Canton-S (Cs – in dark grey box), and from the non-social situation (in open box – see text; n= 2 to 3 repeats of 40 males, p < 0.0001; a#b p<0.003, a#c p<0.03, a#d p<0.007). B. Males with one UAS-VMAT RNAi under a TH-Gal 4 driver (n=4X40) show a trend to have increased social spacing compared to controls (CS n=4X40, TH-Gal/+ n=4X40, VMAT RNAi/+ n=3X40; p < 0.0001; letters indicate statically different groups a#b p<0.003, a#c p<0.0001, b#c p<0.009). C. Males with 2 copies of UAS-RNAi VMAT-A (Dopplex VMAT RNAi) under TH-Gal4 driver (doted box, n=3X40) displays the same trend as the P-element loss of function: increased social spacing, compared to its controls (TH-Gal/+ n=2X40, Dopplex VMAT RNAi/+ n=2X40, all in dark grey boxes). But it is not different from non-social flies (open box). p < 0.0001; a#b p<0.00001. D: Males overexpressing UAS-VMAT under a TH-Gal4 driver (n=6X40) have a slight but statistically significant decrease in social space compared to their controls (UAS-VMAT/+ and TH-Gal4/+, each n=2X40) in dark grey (p<0.02, a#b p<0.02).;
