The genetic and enzymatic processes involved in AMs production, and the regulatory mechanisms that control these pathways in response to environmental signals. Practical applications of <em>Pseudomonas</em> AMs are also explored, particularly in plant disease management, where they function as biopesticides, reducing dependency on chemical pesticides and promoting sustainable farming practices. This review aims to encourage further exploration into AMs, inspiring new explorations into their production and applications.

Semi-natural habitats (SNH) are frequently considered as key winter refuge but their contribution is often not compared with the contribution of adjacent arable crops. We performed a <em>meta</em>-analysis to investigate whether SNH are key overwintering sites relatively to adjacent crops, for two abundant and widespread generalist predator groups in agroecosystems: carabid beetles and spiders. We identified a corpus limited to 19 studies and 114 comparisons between SNH (linear or patch) and arable crops (autumn-sown and spring-sown crops) that monitored predators with traps avoiding predator movement during their overwintering. Our analysis revealed that SNH significantly sheltered higher densities of overwintering spiders than adjacent crops. Concerning carabid populations, densities of overwintering carabids were influenced by the shape of SNH with higher overwintering densities in linear elements (grass strips, flower strips, hedges) than in arable crops. In addition, carabid overwintering density and diversity were higher in SNH when the adjacent crop was a spring-sown crop, indicating a higher sensitivity to agricultural disturbances or low trophic resources.
