<i>Megalurothrips usitatus</i>, also known as common thrips or cowpea thrips, is a widely distributed and highly destructive pest, primarily infesting legume crops. Due to its short generation cycle, high reproductive capacity, and concealed lifestyle, the effectiveness of chemical pesticide control has been continuously diminishing with the modernization of agricultural production and the extensive use of pesticides. <i>Megalurothrips usitatus</i> has gradually developed resistance to various commonly used pesticides, with resistance levels increasing year by year, thus exacerbating the difficulty of pest management and causing significant economic losses to agricultural production. Scholars, both domestically and internationally, have conducted in-depth research using methods from morphology, molecular biology, and ecology, showing that there are three main causes of pest resistance: enhanced detoxification enzymes, reduced sensitivity at target sites, and decreased cuticle penetration. These findings provide a wealth of theoretical support for resistance monitoring and management. The resistance of <i>Megalurothrips usitatus</i> to multiple pesticides is not only a local issue but also affects global agricultural sustainability. Research on the monitoring, risk assessment, and mechanisms of resistance in <i>Megalurothrips usitatus</i> contributes to prolonging the effective use of pesticides, improving control outcomes, and enhancing both the yield and quality of cowpea crops. These studies also provide a scientific basis for developing more effective control strategies and ensuring sustainable agricultural development.
