The role of predatory nematodes in managing plant-parasitic nematodes: community dynamics and microbial implications in tropical soils.

ABSTRACT: Plant-parasitic nematodes (PPNs) pose a significant threat to banana cultivation, particularly in tropical regions like Guam. This study investigates the dynamics of nematode communities associated with banana cultivars, focusing on interactions between predatory nematodes (Mononchus spp.) and PPNs (Meloidogyne spp.), and their implications for soil health. Our aim was to evaluate the response of cultivars to nematode prevalence while characterizing nematode community structure and soil chemical properties. Soil and root samples were assessed for nematode communities. Controlled pot experiments were also performed in tomatoes to evaluate predator-prey interactions. The results showed no differences in nematode densities among the banana cultivars, indicating uniform susceptib
