摘要

由于繁殖投资大,雌蝎是决定是否繁殖的决定性性别。一般来说,雌蝎在不接受雄蝎的生殖要求时,会表现出攻击性性行为。因此,本研究旨在考察雄性 Tityus pusillus 蝎子的生殖尝试次数与交配成功率之间的相关性,同时考虑到雌性的行为反应。在五个月的时间里,每月对 150 对野外捕获的 T. pusillus 蝎子进行行为分析。我们的研究结果表明,尽管雌性对雄性的求偶行为做出了攻击性反应,但雄性的持续性对求偶概率有积极影响。此外,我们还观察到在整个研究期间雌性行为的变化,这表明雌性的接受能力可能与繁殖季节有关。因此,环境因素在调节新热带森林蝎子的繁殖方面可能起着重要作用。

Sexual receptivity of females on Neotropical scorpion Tityus pusillus Pocock, 1893 in response to male reproductive advances

Sexual receptivity of females on Neotropical scorpion Tityus pusillus Pocock, 1893 in response to male reproductive advances

Due to the high reproductive investment, females are the decisive sex when making decisions about whether or not to reproduce. Generally, female scorpions display aggressive sexual behavior in response to male reproductive advances when they are not receptive. However, female receptivity can vary over time, depending on environmental factors favorable to reproduction Thus, the current study aimed to examine the correlation between the number of reproductive attempts by male Tityus pusillus scorpion and mating success over time, considering the female's behavioral response. Behavioral analyses were monthly conducted on 150 T. pusillus field-caught pairs over a five-month period. Our results indicate that despite females reacting aggressively to male advances, the persistence of the male has a positive effect in courtship probability. Furthermore, we observed variations in female behavior throughout the studied period, suggesting that female receptivity might be linked to the reproductive season. Therefore, environmental factors may play a significant role in regulating scorpion reproduction in Neotropical forests.
