摘要:

本研究旨在阐明咖啡豆象(Araecerus fasciculatus)在广东省甘薯仓储中的危害情况,并建立一套快速识别与检测技术体系,为该害虫的田间监测提供支撑。以从仓库中采集的咖啡豆象成虫为试验材料,系统描述该虫的形态特征,并测定其线粒体COⅠ基因序列;基于4种仓储害虫的COⅠ序列比对,设计并筛选出针对咖啡豆象的特异性引物。结果表明,咖啡豆象的线粒体COⅠ基因序列与数据库中该虫已知序列相似度为100%。在设计的10对引物中,经验证筛选出一对咖啡豆象特异性引物,仅能扩增出咖啡豆象的DNA,产生单一且清晰的扩增条带,而对另外4种仓储害虫均无扩增反应。本研究首次系统报道了咖啡豆象对甘薯的危害,可为该害虫的田间监测提供技术支持,对早期预警和综合防控具有重要实践意义。

Abstract:

This study aims to clarify the damage caused by the coffee bean weevil (Araecerus fasciculatus) in sweet potato storage warehouses in Guangdong Province, and to establish a rapid identification and detection technology system to support field monitoring. Using adult coffee bean weevils collected from warehouses as experimental materials, the morphological characteristics of the pest were systematically described, and its mitochondrial COⅠ gene sequence was determined. Based on sequence alignment of COⅠ from four storage pests, specific primers were designed and screened. Results showed that the mitochondrial COⅠ gene sequence of the coffee bean weevil exhibited 100% similarity to known sequences of this pest in the database. Among the 10 pairs of primers designed, one pair specific to the coffee bean weevil was successfully screened through validation. This pair of primers produced a single bright band exclusively for coffee bean weevil DNA, with no amplification observed for the four other pests. This study represents the first systematic report on the damage caused by the coffee bean weevil to sweet potatoes, providing technical support for field monitoring of this pest and had significant practical implications for early warning and integrated pest management.
