Queller and Strassmann will study cooperation and conflict Polistes dominulus, a social wasp that is unusual because its colonies include both close relatives and non-relatives. They will study the degree to which kinship, determined by DNA fingerprinting methods, influences aggression, reproductive sharing, and altruistic helping behavior. They will also study how this unusual genetic structure influences the rules of queen succession and whether the power to determine the new queen lie with asingle strong individual or with the more numerous workers. This study continues the successful tradition of using social insects as model systems for understanding how living things come to be organized into cooperative entities. Kinship is one of the most important correlates of cooperative behavior. Yet there have been few systems where the behavior of both relatives and non-relatives could be compared within the same colony, so P. dominulus provides a unique opportunity for critical tests. The strong conflict over queen succession will allow Queller and Strassmann to study how such conflicts are resolved in cooperative groups. Finally, because P. dominulus is a non-native pest species in the U. S., knowledge of its behavior may be useful ultimately in preserving native biodiversity.

Queller和Strassmann将研究合作和冲突，Polistes dominulus是一种不寻常的社会性黄蜂，因为它的殖民地既包括近亲也包括非近亲。他们将研究由DNA指纹识别方法确定的亲属关系在多大程度上影响攻击性、生殖共享和利他性帮助行为。他们还将研究这种不寻常的基因结构如何影响蚁后继承规则，以及决定新蚁后的权力是掌握在一个强壮的个体手中，还是掌握在更多的工蜂手中。这项研究延续了利用群居昆虫作为模型系统来理解生物如何组织成合作实体的成功传统。亲属关系是合作行为最重要的关联因素之一。然而，很少有系统可以在同一群体中比较近亲和非近亲的行为，因此P. dominulus为关键测试提供了独特的机会。关于女王继承的激烈冲突将允许Queller和Strassmann研究如何在合作群体中解决这种冲突。最后，由于在美国，凤头藤是一种非本地害虫，了解其行为可能最终有助于保护本地生物多样性。
