Summary
This review, published in Integrative Zoology, explores how bottom-up ecological processes — originating with soil microorganisms and propagating through plant physiology to insect herbivores — can shape the sustainability of agricultural ecosystems. Drawing on evidence across microbiology, plant biology, and entomology, the paper likely argues that managing soil microbial diversity and plant–microbe interactions offers leverage for natural pest regulation. The work contributes a multi-trophic perspective to discussions of sustainable farming, situating microbial ecology as foundational to above-ground biodiversity and crop protection.
UK applicability
Although the study is likely international in scope, its findings on microbial-mediated pest suppression and plant resilience are broadly applicable to UK arable and horticultural systems, particularly in the context of integrated pest management and the UK's post-Brexit agri-environment policy ambitions around reducing synthetic pesticide use.
Key measures
Likely measures include plant defence metabolite profiles, insect herbivore fitness and feeding behaviour, microbial community composition, and indicators of ecosystem stability or pest suppression
Outcomes reported
The study likely examines how soil microbial communities influence plant physiology and defence traits, and how these changes cascade upward to affect insect herbivore performance and population dynamics. It probably synthesises evidence on bottom-up trophic linkages as mechanisms underpinning agro-ecosystem sustainability.
