Our study aimed to characterize mating behavior in virgin and once-mated males and females of . We reared the specimens under laboratory conditions and recorded the age at which the organisms began their reproductive activity and the time they remained active. We characterized behavioral acts during mating in two groups-virgin and once-mated organisms. Transitions between behaviors were analyzed using Markov chains and the generated ethograms. The duration of behaviors and the percentage of transitions were compared between the two groups. To characterize the mating behavior of , we adopted a framework commonly used in the literature, dividing mating behavior into three phases: premating, mating, and postmating. (A) Premating: Males search for females and mount and stimulate them, which the females resist through fighting behaviors. (B) Mating: The male mounts the female, which moves around and then stops; the male performs specific movements of the antennae and head and inserts his aedeagus into the female. (C) Postmating: Males exhibit guarding behavior over females. Although differences in pre- and postmating behaviors were observed between virgin and once-mated organisms, the duration of the acts did not show significant differences. These results provide key information on the reproductive behavior of , contributing to a better understanding of their biology and sexual interaction patterns.
我们的研究旨在描述[物种名称]未交配和已交配一次的雄性和雌性的交配行为。我们在实验室条件下饲养标本，记录生物体开始生殖活动的年龄以及它们保持活跃的时间。我们对两组（未交配和已交配一次的生物体）在交配过程中的行为动作进行了特征描述。使用马尔可夫链和生成的行为图谱分析行为之间的转变。比较了两组之间行为的持续时间和转变百分比。为了描述[物种名称]的交配行为，我们采用了文献中常用的一个框架，将交配行为分为三个阶段：交配前、交配和交配后。（A）交配前：雄性寻找雌性，爬上并刺激雌性，雌性通过打斗行为进行抵抗。（B）交配：雄性爬上雌性，雌性四处移动然后停止；雄性进行触角和头部的特定动作，并将其阴茎插入雌性体内。（C）交配后：雄性对雌性表现出守护行为。尽管在未交配和已交配一次 的生物体之间观察到交配前和交配后的行为存在差异，但行为的持续时间没有显著差异。这些结果提供了关于[物种名称]生殖行为的关键信息，有助于更好地理解它们的生物学特性和性互动模式。
