Risk Prediction of Wireworm Damage in Potato Crops and Sustainable Control Strategies

In a context of declining availability of chemical solutions, wireworm larvae (Agriotes spp.) have become major pests of potato crops. The TAUPIC project (2020–2024) brought together a broad consortium to develop risk prediction tools, assess alternative solutions (biocontrol, varieties, companion crops), and initiate integrated pest management strategies. The results show (i) a ranking of risk factors, (ii) strong spatial and temporal variability in infestations, (iii) partial effectiveness of biocontrol (0–45%), (iv) significant varietal differences linked to metabolic profiles, and (v) the development of innovative tools (DNA barcoding, rearing methods, olfactometry). TAUPIC has established a solid knowledge base and paves the way for sustainable protection against wireworms (Agriotes spp.).
