Sugar-feeding by adult ichneumonoid and stephanoid wasps (Hymenoptera) in dry evergreen forest, Thailand

Many temperate parasitoid wasp species are known to consume sugars as adults. However, little is known about their adult nutritional ecology in the tropics. Here we present the results of sugar analyses of adult parasitoid wasps collected in dry evergreen forest in Thailand. Sugars were detected using cold anthrone tests, and the results validated for a subsample using high-performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD). Sugars were detected in 90% of stephanids (n=218), 81% of ichneumonids (n=563), and 60% of braconids (n=1,665). We examined whether the presence or absence of sugar and the amount detected were influenced by family (Braconidae, Ichneumonidae, Stephanidae), body size, sex, life history strategy (idiobiont, koinobiont), or weather (rainy vs drier months). Both the incidence of sugar-feeding and the amount detected were strongly positively correlated with body size, and season. Larger individuals were significantly more likely to b..., , # Sugar-feeding by adult ichneumonoid and stephanoid wasps (Hymenoptera) in dry evergreen forest, Thailand Dataset DOI: [10.5061/dryad.pzgmsbd16](https://doi.org/10.5061/dryad.pzgmsbd16) ## Description of the data and file structure ### Files and variables #### ### File: Supplementary_HPAEC-PAD_.csv **Description:**Â Â High-performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD) results of 118 parasitoid wasp individuals (representative female specimens of 12 parasitoid species. ##### Variables * Family: Family of parasitoid wasps * Subfamily: Subfamily of parasitoid wasps * Genus: Genus of parasitoid wasps * Species: Species of parasitoid wasps * Life_history: Life history of parasitoid wasps * Date: Date the parasitoid wasp was collected * Sex: Sex of parasitoid wasps * Wing: Fore wing length of parasitoid wasps (mm) * Season: Season the parasitoid wasp was collected * Cold_Anthrone: The optical density of cold anthrone test (parasitoid wasp samp...,已知诸多温带寄生蜂成虫会取食糖类物质。然而目前学界对热带地区寄生蜂成虫的营养生态知之甚少。本研究针对在泰国干旱常绿林采集的寄生蜂成虫开展糖类检测分析，现将结果报道如下。 本研究采用冷蒽酮法检测糖类物质，并通过高效阴离子交换色谱-脉冲安培检测法（high-performance anion-exchange chromatography with pulsed amperometric detection, HPAEC-PAD）对部分子样本的检测结果进行了验证。在样本量n=218的冠蜂科标本中，糖类检出率为90%；样本量n=563的姬蜂科标本检出率为81%；样本量n=1665的茧蜂科标本检出率为60%。 本研究探讨了糖类检出与否、检出量是否受以下因素影响：寄生蜂科类（茧蜂科、姬蜂科、冠蜂科）、体型大小、性别、生活史策略（抑育型、续育型），以及采集季（雨季与旱季）。 糖类取食率与检出量均与体型大小及采集季呈显著正相关。体型更大的个体更有可能……，# 泰国干旱常绿林内膜翅目姬蜂总科与冠蜂总科成虫的糖类取食行为 数据集DOI：10.5061/dryad.pzgmsbd16 ## 数据与文件结构说明 ### 文件与变量 #### 文件：Supplementary_HPAEC-PAD_.csv **文件说明：** 包含118头寄生蜂成虫的高效阴离子交换色谱-脉冲安培检测法（HPAEC-PAD）检测结果，样本为12种寄生蜂的代表性雌性标本。 ##### 变量说明： * 科：寄生蜂的科级分类单元 * 亚科：寄生蜂的亚科级分类单元 * 属：寄生蜂的属级分类单元 * 种：寄生蜂的物种 * 生活史：寄生蜂的生活史特征 * 采集日期：寄生蜂的采集时间 * 性别：寄生蜂的性别 * 前翅长：寄生蜂的前翅长度（单位：毫米） * 采集季：寄生蜂的采集季节 * 冷蒽酮检测值：冷蒽酮试验的光密度值（寄生蜂样本……）
