【Aim】This study aims to develop a rapid, sensitive, convenient, and visual loop-mediated isothermal amplification (LAMP) detection method for Albonectria rigidiuscula, providing technical support for the rapid detection and accurate management of this invasive pest.【Method】LAMP primers were designed based on the EF-1α and Tub sequences of A. rigidiuscula, and a set of effective primers was screened. The reaction temperature was optimized, and the specificity and sensitivity of the method were evaluated. Additionally, the host of A. rigidiuscula was detected.【Result】The visual LAMP detection method established in this study achieved the detection of A. rigidiuscula within 1 h. No amplification band was produced for the 19 other pathogenic strains tested, and only A. rigidiuscula exhibited amplification, which demonstrated the excellent specificity of the established method. The optimal detection temperature was 65 ℃, and the detection sensitivity reached 21.84×10^-4 ng·μL^-1. In practical applications, the method achieved an accuracy rate of 100%, and the test results could be intuitively interpreted.【Conclusion】The LAMP method developed in this study for the detection of A. rigidiuscula features a short reaction time, strong specificity, high sensitivity, simple operation, and visual detection results. It is suitable for port quarantine and field detection of A. rigidiuscula.
