Abstract

Abstract. Describing the signals involved in sexual interactions is crucial to understand how mating and fertilization success is achieved. We analyzed sexual interactions in the gonyleptid harvestman Pachyloides thorellii Holmberg, 1878 to test the possibility of associations between female and male behaviors. For that purpose, we recorded 21 sexual interactions of P. thorellii under laboratory conditions and performed fine scaled analyses of the videos. We found three female pre-copulatory behaviors (“Mouth parts protrusion,” “Genital operculum opening,” and “Ovipositor eversion”) that seem to be related to sexual receptivity and cooperation with mating occurrence, and four copulatory behaviors (“Bucking,” “Pulling,” “Body lowering,” and “Leg II movements”) that could be indicating to the male that further stimulation is required or that mating is about to end. We also found that males use multimodal courtship displays that include the exchange of tactile and possibly chemical signals between sexes. This study shows that courtship and copulation in P. thorellii include intense information flow between sexes and female evaluation from the beginning until the end of the sexual interaction.

一种有很多话要说的新热带收割机——厚尾象的性对话
摘要描述性互动中涉及的信号对于理解交配和受精是如何成功实现的至关重要。我们分析了1878年的性激素类收割机Pachyloides thorellii Holmberg的性行为,以测试雌性和雄性行为之间联系的可能性。为此,我们在实验室条件下记录了21次P. thorellii的性互动,并对视频进行了精细的缩放分析。我们发现雌性的三种交配前行为(“嘴部突出”、“生殖器盖打开”和“产卵器外翻”)似乎与交配发生的性接受和合作有关,而四种交配行为(“弯曲”、“拉”、“身体降低”和“腿II运动”)可能表明雄性需要进一步的刺激或交配即将结束。我们还发现雄性使用多种方式求爱,包括两性之间的触觉交换和可能的化学信号交换。本研究表明,从交配开始到结束,P. thorellii的求偶和交配包括两性之间强烈的信息流和雌性的评价。
