In the present study, we report that contact with isolated female antenna significantly increases both the pheromone 3-hydroxy-2-butanone (3H-2B) release and the hemolymph JH III level in all examined aggressive posture-adopting (AP) and NP (non-AP-adopting) socially naïve males, with significantly faster concomitant pre-mating wing-raising behavior in AP as compared to NP males. 3H-2B release and JH III level were significantly increased after mating in both AP and NP males. A positive correlation was observed between mating experience and dominant status. Furthermore, mated-AP males initiated fights more rapidly and fought for a significantly longer duration than mated-NP males; retention with the paired female for 24h did not affect this increase. JH III level and 3H-2B release were significantly increased in dominant males as compared to subordinates. These results suggest that prior mating experience in invertebrates may enhance aggression in subsequent male-male encounters, with accompanying physiological (hormone and pheromone) responses.
在本研究中，我们报告称，与分离的雌性触角接触会显著增加所有被检查的具有攻击性姿势（AP）和非攻击性姿势（NP）的社会新手雄性个体的信息素 3-羟基-2-丁酮（3H-2B）释放和血淋巴 JH III 水平，与 NP 雄性相比，AP 雄性的交配前同时进行的翅膀抬高行为明显更快。在 AP 和 NP 雄性中，交配后 3H-2B 释放和 JH III 水平均显著增加。交配经验与支配地位之间存在正相关关系。此外，与配对雌性一起保留 24 小时不会影响这种增加。与已交配的 NP 雄性相比，已交配的 AP 雄性更快地发起战斗并战斗更长时间；与配对雌性一起保留 24 小时不会影响这种增加。与下属相比，支配雄性的 JH III 水平和 3H-2B 释放显著增加。这些结果表明，无脊椎动物的先前交配经验可能会增强随后的雄性-雄性相遇中的攻击性，伴随着生理（激素和信息素）反应。
