Loop-mediated isothermal amplification (LAMP) is a rapid, specific, cost-effective detection method by amplifying nucleic acid under isothermal conditions. In this study, we used LAMP for detection of Hamiltonella defensa that lives as a facultive endosymbiont of whitefly ‘Bemisia tabaci’. We designed the Hamiltonella-specific primers by targeting 16S ribosomal RNA gene and validated the specificity of one primer set. To find the optimum temperature for our primer set, the LAMP reaction was held at the temperature, 60℃, 62℃ and 65℃. As a result, 62℃ was the optimum reation temperature for LAMP reaction. Specificity of primer set was tested by the reaction to both Trialeurodes vaporariorum and B. tabaci. After the whole procedure, the amplicons by LAMP were visualized by adding SYBR Green to the reaction tube.
