Abstract:

In this study SS-PCR and agarose gel electrophoresis technique were used to select a pair of specific primers from the 15 pairs of primers of designed for Carpomyia vesuviana. Five fruit fly species, Bactrocera dorsalis, B.cucurbitae, B.tau, B. correcta and B.zonata, were used to determine the primer specificity. A series of genomic DNA dilution of C.vesuviana, 40, 20, 10, 1, 0.1, 0.01, and 0.001 ng·μL-1, were used to detect the sensitivity of SS-PCR. The results showed that the detection limit of SS-PCR was less than 0.01 ng·μL-1, and the optimum template DNA concentration was between 1 ng and 20 ng·μL-1. The designed primers could be used for amplifying the DNA of C.vesuviana at different stages. The developed SS-PCR method can be used for identification, inspection and monitoring of C.vesuviana, which would have an important significance in preventing the insect from spreading any further.

Key words: SS-PCR, Carpomyia vesuviana, agarose gel electrophoresis, identification
