In solitary bees, monandry is common in several species. Post-copulation strategies exerted by males to prevent females from mating with other males are known and vary between species. We studied a population of Epicharis dejeanii(Centridini) analyzing the reproductive aspects. The average mating time and the behavior of the couples were observed. Males performed synchronized movements of the legs and antennae in addition to vibrations that generated a loud sound. The females remained static, starting movements with their legs to finish the mating after approximately 50 s. During the mating, the females’ sting was kept exposed. The males inserted the aedeagus into the female’s genital opening but kept out the genitalia. The male’s post-copulatory behavior seems to be performed simultaneously during mating.

采油蜂 Epicharis dejeanii (Apidae: Centridini) 的繁殖行为

在独居蜜蜂中，monandry 在几个物种中很常见。雄性为防止雌性与其他雄性交配而采取的交配后策略是已知的，并且因物种而异。我们研究了 Epicharis dejeanii (Centridini) 的种群，分析了生殖方面。观察平均交配时间和夫妇的行为。除了产生响亮声音的振动外，雄性还进行腿和触角的同步运动。雌性保持静止，在大约 50 秒后开始用腿运动以完成交配。在交配过程中，雌性的螫刺一直暴露在外。雄性将 aedeagus 插入雌性的生殖器开口，但将生殖器拒之门外。雄性的交配后行为似乎在交配过程中同时进行。
