Enchenopa树跳的配对过程涉及雌雄信号二重奏。这些二重奏提供了附近个体的交配决策信息。我们用二重奏回放处理测试了Enchenopa的配偶选择复制。Enchenopa的配偶偏好不受回放的影响。没有复制可能代表对固定偏好的选择,而不是没有机会。在配偶选择中,社会学习可能采取配偶选择复制或反复制的形式,由此模仿或避免观察到的交配决定。或者,独立的交配决定可能基于先天偏好或早期社会学习。虽然交配选择复制在一些动物类群中很普遍,但对节肢动物的研究有限,结果也不一致。我们测试这些假设,Enchenopa树跳(半翅目:膜翅目)。Enchenopa雄性产生植物传播的振动广告信号,雌性通过选择性地与雄性对唱来表达它们的配偶偏好。植物上的个体可以在配对过程中监测这些公共信号。我们将女性随机分配到治疗二重唱,包括不吸引人或有吸引力的男性信号,然后是长时间的女性治疗反应(热情),短时间的女性治疗反应(保留)或没有女性治疗反应。我们描述了治疗二重唱前后的测试女性的交配偏好。我们发现,女性的配偶偏好不受治疗二重奏。相反,女性具有一致的个体差异,这支持了独立择偶假设,拒绝了两个社会学习假设。我们的研究结果表明,独立择偶并不一定代表缺乏机会,从择偶的直接社会背景的社会影响。
HighlightsPair formation in Enchenopa treehoppers involves male–female signal duets.These duets provide information about the mating decisions of nearby individuals.We tested for mate choice copying in Enchenopa with duet playback treatments.Enchenopa mate preferences were unaffected by the playbacks.No copying may represent selection for fixed preferences, instead of no opportunity.In mate choice, social learning may take the form of mate choice copying or anticopying, whereby observed mating decisions are either mimicked or avoided. Alternatively, independent mating decisions may be based on innate preferences or early life social learning. While mate choice copying is widespread among some animal taxa, research in arthropods is limited and results are mixed. We tested these hypotheses using Enchenopa treehoppers (Hemiptera: Membracidae). Enchenopa males produce plant-borne vibrational advertisement signals and females express their mate preferences by selectively duetting with males. Individuals on the plant can monitor these public signals during pair formation. We randomly assigned females to treatment duets consisting of either unattractive or attractive male signals, followed by a long female treatment response (enthusiastic), a short female treatment response (reserved) or no female treatment response. We described the test females' mating preferences before and after the treatment duet. We found that female mate preferences were not affected by the treatment duets. Instead, females had consistent individual differences, which supports the independent mate choice hypothesis and rejects both social learning hypotheses. Our findings suggest that independent mate choice does not necessarily represent a lack of opportunity for social influences from the immediate social context of mate choice.
