White-spotted flower chafer adult (Protaetia brevitarsis, Coleoptera: Scarabaeidae), a serious omnivorous pest in regions with multiple fruits and crops, was studied to gain a deeper understanding of its damage patterns. DNA molecular tracking technology was used to identify host plant residues in adult P. brevitarsis midgut, and plant species with the most availability were determined during their growing season. Combining the 2019 and 2021 results, it was found that adults in the multi-cropped area fed on 32 plant species from 23 families, with grape (Vitis vinifera, 40%), peach (Prunus perisica, 23%) and mulberry (Morus alba, 14%) making up the majority of their diet. Some adults fed on multiple plant hosts, with four species detected in one adult and two to three species detected in one-third of adults. Adults shifted among host species during the season, moving from mulberry or grape to peach and then back to grape. These results provide a scientific basis for in-depth research to develop green integrated control technologies against P. brevitarsis adults.
白星花金龟成虫（Protaetia brevitarsis，鞘翅目：金龟科）是多种水果和农作物种植区的一种严重杂食性害虫，为了更深入了解其危害模式，对其进行了研究。采用DNA分子追踪技术鉴定白星花金龟成虫中肠内的寄主植物残体，并确定其生长季节中可利用性最高的植物种类。综合2019年和2021年的研究结果发现，多作物种植区的成虫取食了来自23个科的32种植物，其中葡萄（Vitis vinifera，40%）、桃（Prunus perisica，23%）和桑（Morus alba，14%）占其食物来源的大部分。一些成虫取食多种植物寄主，在一只成虫中检测到4种，在三分之一的成虫中检测到2至3种。成虫在季节内会在寄主物种间转移，从桑或葡萄转移到桃，然后再回到葡萄。这些结果为深入研究开发针对白星花金龟成虫的绿色综合防治技术提供了科学依据。
