Figure 9.
An optimized qPCR assay performed to assess the specificity of the DorFP1/DorRP1 SSPs using laboratory-extracted DNA templates from populations of B. dorsalis from UP (both maggot and adult), UK, HP, AS, WB, and BR. This was compared with B. correcta, B. zonata, B. digressa, Z. cucurbitae, and Z. tau, with inclusion of two NTC. (A) The graph illustrates the change in fluorescence signal (ΔRN) against the number of PCR cycles, representing successful amplification of samples containing B. dorsalis template DNA. (B) Melting curve analysis demonstrating species specificity of SSP for B. dorsalis, plotted against fluorescence derivative units (-RN’), and temperature (°C).
