is a dioecious plant that is rich in various metabolites and widely distribute in Asia. is a rodent that often causes damage to crops, especially in the Dongting Lake region of China. There is a wide overlap in the distribution areas for the above species and the feeds on the leaves of the . Preliminary experiments have shown that the reproduction of is inhibited after feeding on the leaves of the .
In order to explore the potential of using to develop botanical pesticides, we investigated the palatability and reactive substances. The feeding frequency of on leaves to that of on daily fodder and that is the primary food for the wild population were compared. We also attempted to identify the responsive substances in leaves that were bitten by using metabolome analysis.
In general, leaves exhibited a stronger attraction to . foraged leaves more frequently, and the intake was higher than that of the other two. Differential metabolites were screened by comparing normal leaves and leaves bitten by , meanwhile with the intervention of clipped leaves. A total of 269 substances were screened, and many of these were involved in the biosynthesis of secondary metabolites, including terpenoids and alkaloids. These substances may be related to the defense mechanism of against herbivores.
These findings support further research examining animal-plant interactions and simultaneously provide insights into the utilisation of resources and the management of rodents. The good palatability and the defense of leaves suggest that they have the potential to contribute in development of plant rodenticide.
[植物名称]是一种雌雄异株的植物，富含多种代谢产物，广泛分布于亚洲。[啮齿动物名称]是一种啮齿动物，常对农作物造成损害，尤其是在中国的洞庭湖地区。上述物种的分布区域有很大重叠，且[啮齿动物名称]以[植物名称]的叶子为食。初步实验表明，[啮齿动物名称]取食[植物名称]的叶子后繁殖受到抑制。
为了探索利用[植物名称]开发植物源农药的潜力，我们研究了其适口性和活性物质。比较了[啮齿动物名称]取食[植物名称]叶子的频率与取食日常饲料以及野生种群主要食物[另一种食物名称]的频率。我们还试图通过代谢组分析鉴定被[啮齿动物名称]啃咬的[植物名称]叶子中的响应物质。
总体而言，[植物名称]的叶子对[啮齿动物名称]表现出更强的吸引力。[啮齿动物名称]更频繁地取食[植物名称]的叶子，摄入量高于其他两者。通过比较正常叶子和被[啮齿动物名称]啃咬的叶子，并在有修剪叶子干预的情况下，筛选出差异代谢产物。共筛选出269种物质，其中许多参与次生代谢产物的生物合成，包括萜类化合物和生物碱。这些物质可能与[植物名称]抵御食草动物的防御机制有关。
这些发现支持进一步研究动植物相互作用，同时为[植物名称]资源的利用和啮齿动物的管理提供见解。[植物名称]叶子良好的适口性和防御能力表明它们有潜力为植物灭鼠剂的开发做出贡献。
