The cactus (), known as pitahaya or dragon fruit, is one of the pitaya species of economic importance for different countries worldwide, particularly in China, Mexico, Australia, Vietnam, Indonesia, and the United States, among other countries. On the other hand, () is a pest insect found in Mexico, known as the cactus weevil or borer. This study reports, for the first time, feeding and damage to the vascular stem and flower bud of wild plants in Jalisco, Mexico. Field sampling was conducted in wild populations of between July and October 2024. The results of our study confirm that actively feeds on , causing damage to the plant, primarily to the vascular cylinder of mature and immature stems, as well as to flower buds and tissues. During monitoring, we observed a total of nine eggs, nine larvae, and sixteen adults in different plant samples, confirming that S. undatus serves as a reproductive host for . The results highlight the threat of to in the State of Jalisco, which highlights the need to incorporate new agricultural strategies to mitigate the impact that this insect has on pitahaya.
仙人掌（），又称火龙果，是一种对全球不同国家具有经济重要性的火龙果品种，尤其是在中国、墨西哥、澳大利亚、越南、印度尼西亚和美国等国家。另一方面，（）是一种在墨西哥发现的害虫，被称为仙人掌象鼻虫或蛀虫。本研究首次报道了其对墨西哥哈利斯科州野生植物维管束茎和花芽的取食及危害情况。于2024年7月至10月在野生种群中进行了实地采样。我们的研究结果证实，（）积极取食（），对植株造成损害，主要是对成熟和未成熟茎的维管束柱以及花芽和组织。在监测过程中，我们在不同的植物样本中总共观察到9枚卵、9只幼虫和16只成虫，证实了量天尺是（）的繁殖宿主。研究结果凸显了（）对哈利斯科州（）的威胁，这突出表明需要采用新的农业策略来减轻这种昆虫对火龙果的影响。
