Biodiversity loss impacts top-down regulation of insect herbivores across ecosystem boundaries

organisms (at 50 % loss).Equally, random loss of BC organisms affects herbivore regulation to a greater extent (13.8 % at 50 % loss) than herbivore loss mediates their preservation (11.4 %).Yet, under moderate biodiversity loss, (non-pest) herbivores prove highly susceptible to loss of BC organisms.Our topological approach spotlights how agriculturally-subsidized BC agents benefit vegetation restoration, while non-pest herbivores uphold biological control in on-and off-farm settings alike.Our work underlines how the on-farm usage of endemic biological control organisms can advance conservation, restoration, and agricultural sustainability imperatives.We discuss how integrative approaches and close interdisciplinary cooperation can spawn desirable outcomes for science, policy and practice.
