Campoplex capitator is an ichneumonid parasitoid with a narrow host range, comprising grapevine moth pests. Despite being considered one of the possible candidates for biocontrol of Lobesia botrana, knowledge about its biology is limited and mass‐rearing for commercial purposes is still lacking. This research provides a quantitative analysis of the C. capitator courtship and mating behavior. C. capitator mating sequence was analyzed by high‐speed video recordings. Main behavioral parameters, with special reference to male wing fanning and antennal tapping, were quantified and linked with mating success. Furthermore, we analyzed the occurrence of population‐level behavioral asymmetries during C. capitator sexual interactions and their impact on male success. Results showed that male wing fanning was crucial to successfully approach the female. Males achieving higher mating success performed wing‐fanning at higher frequencies over unsuccessful ones. After wing fanning, most of males palpated the female's body with their antennae, before attempting copulation. The overall mating success was >70%, with a rather long copula duration (254.76 ± 14.21 s). Male wing‐fanning was lateralized on the left at population level, while antennal tapping displays were right‐biased. Side‐biased male displays do not differ in terms of frequency and duration of their main features. This research adds basic knowledge to the C. capitator behavioral ecology. Since rearing protocols for C. capitator are being developed, male wing fanning frequency may represent a useful benchmark for monitoring mate quality over time, tackling mating success reductions due to prolonged mass‐rearing.

扇动频率作为促进雄性交配成功的释放器 - 对 Lobesia botrana 寄生蜂 Campoplex captor 求偶行为的高速视频分析

Campoplex captor 是一种寄主范围狭窄的 ichneumonid 寄生蜂，包括葡萄蛾害虫。尽管被认为是 Lobesia botrana 生物防治的可能候选者之一，但对其生物学的了解是有限的，并且仍然缺乏用于商业目的的大规模饲养。本研究提供了对 C. capator 求偶和交配行为的定量分析。C. 头尾交配序列通过高速视频记录进行分析。主要行为参数，特别是雄性翅膀扇动和触角敲击，被量化并与交配成功相关联。此外，我们分析了 C. capator 性互动期间人口水平行为不对称的发生及其对男性成功的影响。结果表明，雄性扇动翅膀对于成功接近雌性至关重要。获得更高交配成功率的雄性比不成功的雄性以更高的频率进行扇动。在扇动翅膀后，大多数雄性在尝试交配之前用触角触摸雌性的身体。总体交配成功率 > 70%，交配持续时间相当长（254.76 ± 14.21 s）。雄性扇动在种群水平上偏向左侧，而触角轻敲显示则偏右。偏向男性的表现在其主要特征的频率和持续时间方面没有差异。这项研究为 C. capator 行为生态学增加了基础知识。由于正在制定 C. capator 的饲养协议，雄性翅膀扇动频率可能代表一个有用的基准，用于随着时间的推移监测配偶质量，解决因长时间大量饲养而导致的交配成功率下降问题。
