FINAL RECIPROCAL TESTS OF TEN WORKERS BETWEEN COLONY 
FRAGMENTS B' AND B" 
February 15-16, 1983:92-93 days after first reciprocal tests 11/15/82 
February 15\ 
Workers BH into BU 
3:45 p.m. 10 workers introduced from BO 
Many workers clustered inside nest entrance, but no hostility, until 
4:10 p.m. Two workers “clinched” and stinging near nest entrance. 
4:15 p.m. 
Activity much diminished at nest entrance. The “clinched” pair not 
seen. 
4:25 p.m. 
4:30 p.m. 
Generally quiet but two “alien” workers seen being dragged in arena. 
Generally very quiet, but the two “alien” workers still being dragged 
in arena. 
4:35 p.m. 
Some activity around nest entrance, and one or two males emerging. 
No hostility observed. 
5:00 p.m. Entirely quiet in arena with only two workers out. Some activity 
6:00 p.m. 
about nest entrance. No conflict. 
One “alien” worker seen being dragged by two others. Otherwise all 
normal and quiet. 
February 16: 
8:00 a.m. 
Arena quiet with one or two males emerging from nest. 
However, 1 dead worker (presumably alien) being dragged about 
arena, and two freshly killed workers in corner. These three 
presumably BD aliens. 
Thus the general picture was one of no general arousal (as before) but ultimate 
individual hostility to three out of ten workers, with eventual killing. Entirely 
confirmatory of earlier results. 
February 15: 
Workers Bit into BD: 
3:45 p.m. 10 workers introduced from B. 
All introduced workers immediately disappeared into BU nests, 
without causing any sign of disturbance. 
4:20 p.m. Only 5 workers seen outside nests. No conflict and no signs of 
disturbance. 
4:25 p.m. All very quiet in arena. Only 2 workers out. No conflict. 
4:30 p.m. All entirely quiet. 1 worker only seen in arena. No conflict. 
4:35 p.m. Completely quiet. One worker seen in arena. No conflict. 
5:00 p.m. Completely quiet. One worker seen in arena. No conflict. 
6:00 p.m. All completely quiet. I worker seen in arena. No conflict.
