Crayfish establish social dominance hierarchies through agonistic interactions, and these hierarchies are maintained through assessment of social status. Chemical signals influence several aspects of fighting behavior, but the specific chemosensory sensilla involved in detecting these signals in crayfish are unknown. The goal of our study was to examine the importance of aesthetasc sensilla--olfactory sensors on the antennules of decapod crustaceans--in regulating changes in fighting behavior in crayfish, Procambarus clarkii, over the course of repeated pairings. We selectively ablated aesthetascs from pairs of crayfish after the first day of trials and compared the behavior of these ablated animals to that of pairs of intact controls. Results show that unablated crayfish significantly decreased the number and duration of fights over repeated pairings, whereas crayfish lacking aesthetascs continued to engage in similar amounts of fighting across all three trial days. This difference shows that aesthetascs regulate fighting behavior in P. clarkii.

嗅觉通路在小龙虾的激动行为中的作用,克拉克原螯虾。

小龙虾通过竞争性互动建立社会支配地位等级,这些等级制度通过社会地位评估来维持。化学信号影响战斗行为的几个方面,但在小龙虾中检测这些信号所涉及的特定化学感应器尚不清楚。我们研究的目的是检查美学感受器——十足目甲壳类动物触角上的嗅觉传感器——在调节小龙虾、克拉克原螯虾在重复配对过程中的战斗行为变化方面的重要性。在试验的第一天后,我们有选择地消融了成对小龙虾的美学,并将这些消融动物的行为与成对的完整对照的行为进行了比较。结果表明,未消融的小龙虾在重复配对中显着减少了打架的次数和持续时间,而缺乏审美感的小龙虾在所有三个试验日中继续进行相似数量的打架。这种差异表明美学调节了 P. clarkii 的战斗行为。
