How effective are entomopathogenic nematodes for vine weevil (Coleoptera: Curculionidae) biological control? A meta‐analysis

EPNs provide reliable biological control of vine weevil larvae under field and semi-field conditions, with effectiveness enhanced by warmer soil temperatures and protected growing environments. Although average effects are large and consistent, practitioners should expect considerable variability in outcomes and prioritise applications during warm conditions in protected environments where feasible. A lack of robust differences among species suggests that selection can be based on practical considerations such as cost and availability. © 2025 The Author(s).
