蓟马Scirtothrips dorsalis Hood(Thysanoptera:Thripidae)是一种入侵性害虫,对美国农业和贸易构成重大经济威胁。本研究利用DNA序列数据和聚合酶链反应(PCR)技术,建立了一个诊断沙门氏菌的分子标记。背肌分析了不同种类的蓟马(包括S.背肌设计引物和PCR循环参数,用于扩增单标记片段。dorsalisITS2 rDNA。对10种蓟马进行了特异性试验,对15种S. dorsalis种群的遗传多样性,以及引物敏感性和稳健性的测试都证明了该标记的诊断实用性。这种诊断PCR方法提供了一种快速、简便、可靠的分子技术,可用于S。背肌
The thrips Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is an invasive pest that poses a significant economical threat to U.S. agriculture and trade. In this study, DNA sequence data and polymerase chain reaction (PCR) were utilized to develop a molecular diagnostic marker for S. dorsalis. The DNA sequence variation from the internal transcribed spacer 2 (ITS2) region of nuclear ribosomal DNA (rDNA) was analyzed from various thrips species, including S. dorsalis. A primer set and polymerase chain reaction cycling parameters were designed for the amplification of a single marker fragment of S. dorsalis ITS2 rDNA. Specificity tests performed on ten thrips species, efficacy tests performed on fifteen S. dorsalis populations, and tests on primer sensitivity and robustness all demonstrated the diagnostic utility of this marker. This diagnostic PCR assay provides a quick, simple, and reliable molecular technique to be used in the identification of S. dorsalis.
