Abstrakt: Background: The grey garden slug (Deroceras reticulatum) is considered the most damaging slug pest in global agriculture. Control methods primarily rely on chemical pesticides, which pose environmental risks and potential hazards to human health. There is a need for sustainable management alternatives such as biologically-based slug control options. However, the efficacy of nonchemical measures for controlling pest slug populations remains limited, particularly in the context of variable outdoor conditions. Neuropeptides and their corresponding receptors have been proposed as promising biological targets for the development of new pest management strategies.
Results: A total of 23 bioactive peptides belonging to the PRX family, previously identified from the grey garden slug, D. reticulatum, were injected into or fed to this species. The detrimental effects of these peptides, including a reduction in body weight and an inhibition of feeding activity, were evaluated in feeding choice tests with D. reticulatum. Furthermore, the bioactive peptide formulated with a lipid particle demonstrated a feeding deterrent effect. One of the myomodulin (MM) peptides, APPLPRY, demonstrated a significant reduction in feeding activity, resulting in a reduction in slug weight or mortality in just 30 min.
Conclusion: The results represent the first evidence of a bioactive peptide having detrimental effects on D. reticulatum including causing feeding deterrent for this slug pest. The in vivo results provide insights into the potential development of active ingredients for managing slugs in the field. © 2024 Society of Chemical Industry.
