In this study, seven internal reference genes of Bactrocera dorsalis under various quarantine treatments were screened, with G6PDH and RPL-32 identified as the most stable genes for analyzing phytosanitary treatment in B. dorsalis. This research provides a foundation for further understanding the resistance mechanisms of B. dorsalis to abiotic stresses.
Simple Summary:& nbsp;In this study, seven internal reference genes (G6PDH, GAPDH, RPL-32, Rpl-13, Rps-3, a-tub, and 18S) of Bactrocera dorsalis under different quarantine treatments (heat treatment, cold treatment, methyl bromide fumigation, and irradiation) were screened. Finally, the most stable internal reference gene was selected, which laid a foundation for the further study of its resistance mechanisms to some abiotic stresses. Bactrocera dorsalis is a major pest that causes serious damage to many fruits. Although phytosanitary treatment methods have been developed for Bactrocera control, there is a lack of information related to the gene expression pattern of B. dorsalis subjected to phytosanitary treatment conditions. Prior to quantitative reverse transcription polymerase chain reaction analysis of the most stable reference genes in B. dorsalis (Diptera: Tephritidae), B. dorsalis third-instar larvae were exposed to various phytosanitary treatments; seven candidate reference genes (18S, G6PDH, GAPDH, RPL-13, RPL-32, RPS-3, and a-Tub) were amplified and their expression stabilities were evaluated using geNorm, NormFinder, BestKeeper, and RefFinder algorithms. Different reference genes were found under different stress conditions. G6PDH was the most stable gene after heat treatment. After cold treatment, a-Tub exhibited the highest expression stability. G6PDH expression stability was the highest after fumigation with methyl bromide. RPL-32 showed the highest expression stability after irradiation treatment. Collectively, RefFinder analysis results revealed G6PDH and RPL-32 as the most suitable genes for analyzing phytosanitary treatment in B. dorsalis. This study provides an experimental basis for further gene expression analyses in B. dorsalis subjected to various phytosanitary treatments, which can aid in the development of novel phytosanitary treatments against insect pests.
