Pathogenicity of Serratia marcescens strains as biological control agent: Implications for sustainable pest management

Abstract The escalating demand for sustainable and eco‐friendly pest management strategies has raised interest in harnessing the pathogenic potential of microorganisms. Serratia marcescens , a Gram‐negative bacterium, has emerged as a potential biological control agent for sustainable pest management. This review critically examines the history, biology, identification, and pathogenicity of S. marcescens strain with their potential application in pest management. The diverse mechanisms employed by the strain to exert control over pests, including the production of metabolites and the induction of systemic resistance in plants, are examined. The review also summarizes the ecological significance and global distribution of S. marcescens associated with the use of S. marcescens in biological control strategies. Furthermore, the usage efficacy of S. marcescens over other conventional chemicals is discussed. A comprehensive understanding of the pathogenic potential of S. marcescens strains as biological control agents is crucial for developing effective and sustainable pest management strategies. This review consolidates current research advances on S. marcescens , and provides insights into the prospects and challenges of using S. marcescens for integrated pest management.
