Behavior scores for focal embiids (Haploembia tarsalis, H. solieri, Oligotoma nigra) interacting in dyads

Two hypotheses tested: Behavioral Syndrome of Social Distancing vs Parasite Trigger Hypothesis. Testing if Haploembia tarsalis focal insects react to parasitized or non-parasitized individuals, placed in dyads in a burrow arena, in the same. They were analyzed for presence of a gregarine parasite, which commonly infects them in the field. These asexual embiids did show social distancing as can be seen in the data, where all individuals retreat and attempt to escape from each other irrespective of parasitism status. Two relate species were tested as comparison, and they show typical embiopteran behaviors of sitting together (gregaraious).. In the data set, the values show a summary score reflecting how a focal insect reacted to another in a 10 minute trial. Every time they touched each other, their behaviors were scored for 10 s following the touch. Retreat and Locomotion reflect agitation and are scored as negative values, the other acts (Sit Alone, Sit Nearby, and Total Spin) are neutral to gregarious and are positive values.本实验检验了两项假说：社交距离行为综合征（Behavioral Syndrome of Social Distancing）与寄生虫触发假说（Parasite Trigger Hypothesis）。实验以足跗单孔纺足虫（Haploembia tarsalis）为受试个体，将其以二元组（dyads）形式置于洞穴竞技场（burrow arena）中，检验受试个体对被寄生与未被寄生同类的行为反应。所有研究对象均经簇虫（gregarine parasite）感染情况检测，该类寄生虫在野外环境中普遍寄生于此类昆虫体内。 实验数据表明，这类无性生殖的纺足目昆虫（embiids）确实表现出社交距离行为：无论同类是否被寄生，所有受试个体均会后退并试图逃离彼此。另有两种近缘物种被作为对照纳入实验，它们表现出典型的纺足目群居（gregarious）行为，即个体间会聚集共处。 本数据集的数值为汇总得分，反映受试个体在10分钟实验试次内对另一受试个体的行为反应。每当两只个体发生接触后，研究人员会对接触后10秒内的昆虫行为进行评分。其中，后退（Retreat）与移动（Locomotion）行为反映了昆虫的躁动状态，被计为负值；其余行为（独自静坐（Sit Alone）、邻近静坐（Sit Nearby）、完全旋转（Total Spin））均属于中性至群居倾向类行为，被计为正值。
