With the purpose of broadening knowledge on the evolution of life history strategies and behaviour of fruit flies within the tribe Carpomyini, the natural history and mating behaviour of the poorly known species Rhagoletotrypeta pastranai Aczél, are described for the first time. Larvae of R. pastranai were recovered from infested Celtis tala Gillies ex Planch and Celtis iguanaea (Jacq.) Sarg. during a 2-month fruiting period. Adults emerged from the recovered pupae after an average of 144.9 ± 3.9 days for females and 143.2 ± 3.38 days for males, suggesting that most individuals became dormant. Results of a variable winter length study suggested that environmental factors other than winter length may regulate dormancy/diapause duration in this subtropical species. Under laboratory conditions, R. pastranai adults lived an average of 51.13 ± 3.06 days in case of females and 48.08 ± 3.76 days in case of males, and required 5–15 days to reach sexual maturity. Behavioural observations under confinement revealed scarce sexual activity but sufficed to determine that, as in other members of the tribe Carpomyini, R. pastranai exhibits a male resource defence mating system. We discuss our findings emphasizing the importance of documenting the natural history and behaviour of unknown species of family Tephritidae and additionally, we highlight the necessity of future research to understand factors regulating dormancy/diapause and the evolution of life history strategies and sexual behaviour of subtropical species.

亚热带果蝇 Rhagoletotrypeta Pastranai (Diptera: Tephritidae) 的生活史、休眠调节、生殖生理和基本行为

为了拓宽关于 Carpomyini 部落内果蝇生活史策略和行为演变的知识，了解鲜为人知的物种的自然历史和交配行为Rhagolettotrypeta pastranaiAczél，第一次被描述。幼虫R. Pastranai从感染中恢复毛竹Gillies ex Planch 和凯尔特鬣蜥（雅克）萨尔格。在2个月的结果期。成虫在雌性平均 144.9 ± 3.9 天和雄性平均 143.2 ± 3.38 天后从恢复的蛹中出现，这表明大多数个体都处于休眠状态。一项可变冬季长度研究的结果表明，冬季长度以外的环境因素可能会调节这种亚热带物种的休眠/滞育时间。在实验室条件下，R. Pastranai成年女性平均寿命为 51.13 ± 3.06 天，男性为 48.08 ± 3.76 天，达到性成熟需要 5-15 天。禁闭期间的行为观察显示性活动很少，但足以确定，与 Carpomyini 部落的其他成员一样，R. Pastranai表现出雄性资源防御交配系统。我们讨论了我们的研究结果，强调了记录未知物种的自然历史和行为的重要性 Tephritidae 此外，我们强调了未来研究了解调节休眠/滞育的因素以及亚热带物种生活史策略和性行为的演变的必要性.
