Apply- ing a new layer of nest constniction ma- terial to the nest stem effectively covers up the previous day's coat of defense secre- tion. In terms of the most efficient use of the defense secretion, it is obviously best to apply the entire day's suppK- of nest con- struction secretion to the stem first, then put the defensive secretion on top of that, rather than mixing the two activities throughout the day. The heaviest concen- tration of rubbing activity did indeed closely follow mouthing (Fig. 5D). IX. DOMINANCE AND CASTE DETERMINATION A. The Nature of Domixaxce- SUBORDIXAXCE BeHA\T[OR In encounters between t\vo females of a colony one of the pair usually dominated over the other. The violence with which one individual dominated another varied, as did the degree to which the subordinate individual showed submissive behavior. In the mildest form of domination the dominant wasp merely turned and darted or rushed toward the subordinate but did not make contact with it. The subordinate either did not respond at all, merely flinched, or moved away. In the most typical form of domination the dominant rushed at the subordinate and violently mouthed its body with the mandibles while antennating it vigorously. This was often accompanied by a rapid forward-and-back\vard "pecking" motion of the entire body. The face and top of the head of the subordinate were most fre- quently attacked in this way, but the thorax, \\dng bases, abdomen, and legs were also attacked. The
