Data for Manuscript: Molecular gut content analysis reveals predator feeding preferences and potential for biological control of aphids in sugar beet fields

The present dataset contains the results (positive/negative detections for Aphis fabae or Myzus persicae) of gut content PCR conducted on predatory arthropods collected in Danish sugar beet fields in 2022 and 2023. Additionally, the dataset contains results of digestion trials for Coccinella septempunctata, Cantharis lateralis and Chrysoperla carnea fed with Aphis fabae and Myzus persicae本数据集收录了2022年与2023年于丹麦甜菜田采集的捕食性节肢动物的肠道内容物PCR检测结果，检测对象为豆蚜（Aphis fabae）与桃蚜（Myzus persicae），记录了二者的阳性/阴性检出情况。此外，本数据集还包含七星瓢虫（Coccinella septempunctata）、侧斑芫菁（Cantharis lateralis）以及大草蛉（Chrysoperla carnea）分别取食豆蚜与桃蚜后的消化试验结果。
