Data on early brood nestmate recognition behaviour and chemical signaling in ants

The dataset shared are: - Abundance of hydrocarbons in surface extracts of single eggs and L1 larvae of 6 different formicoid ants to asses inter-specific and inter-colonial variations obtained from GC-MS experiments. - Cumulative durations of antennation of brood items - Number of brood items retrieved Both behavioural data were gather during 15 minutes behavioural trials where 6 nestmate ant workers were presented 3 eggs or 3 L1 larvae that were either all nestmate, non-nestmate or hetero-specific in an arena with a refuge. The studied Formicidae species are: Aphaenogaster senilis (Myrmicinae), Camponotus aethiops (Formicinae), Formica fusca (Formicinae), Lasius niger (Formicinae), Messor barbarus (Myrmicinae) and Tapinoma darioi (Dolichoderinae).

本次共享的数据集包含以下内容：
1. 6种蚁类的单枚虫卵及1龄幼虫（L1 larvae）表面提取物中的烃类物质丰度数据，该数据源自气相色谱-质谱联用（GC-MS）实验，用于评估物种间及种群间的差异；
2. 蚁类对育幼对象的触角探索总时长；
3. 取回的育幼对象数量。

上述两类行为学数据均采集自时长15分钟的行为学测试：测试中向6只同巢工蚁提供3枚虫卵或3只1龄幼虫，这些幼体分为同巢、非本巢及异种三个类别，测试环境为带有庇护所的行为试验箱（arena）。

本次研究涉及的蚁科（Formicidae）物种包括：亮结蚁（Aphaenogaster senilis，切叶蚁亚科Myrmicinae）、哀弓背蚁（Camponotus aethiops，蚁亚科Formicinae）、黑毛蚁（Formica fusca，蚁亚科Formicinae）、黑蚁（Lasius niger，蚁亚科Formicinae）、野蛮收获蚁（Messor barbarus，切叶蚁亚科Myrmicinae）以及达里奥臭蚁（Tapinoma darioi，臭蚁亚科Dolichoderinae）。
