在实验室中检查了雄性果蝇 Drosophila melanogaster 和 D. simulans 对食物杯的防御。每个人参与的领土冲突数量和获胜数量各不相同。遭遇的结果取决于居民身份，在较小程度上取决于体重。与非升级冲突相比，居民在升级战斗中获胜的频率较低，而居民在前者中的成功可能是由于体重不对称。在升级的遭遇中，直立翅膀的展示更为常见，但没有提供有关体重或居住状态的信息。 D. simulans 的升级取决于获胜者和失败者之间的体重差异。与拟果蝇相比，黑腹果蝇的遭遇时间较短，战斗升级的发生率也较低。参与领地防御的雄性黑腹果蝇较少。有领地意识的雄性比无领地意识的雄性在交配方面更成功。
Defence of food cups by males of the fruitflies Drosophila melanogaster and D. simulans was examined in the laboratory. Individuals differed in the number of territorial encounters they participated in and the number they won. The outcome of encounters depended on resident status and, to a lesser extent, body weight. Encounters with escalated fighting were less frequently won by resident that non-escalated encounters, and the success of residents in the former could be accounted for by the body weight asymmetry. A display involving erect wings was more common in escalated encounters, but provided no information on body weight or resident status. Escalation in D. simulans depended on the difference in body weight between winners and losers. D. melanogaster had shorter encounters than D. simulans, and a lower incidence of escalated fighting. Fewer D. melanogaster males participated in territorial defence. Territorial males were more successful in mating than non-territorial males.
