In some contexts, stakeholders can be forced to personally act following their own observations and risk perception instead of science recommendation. In particular, biological invasions need rapid control actions to reduce potential socioecological impacts, while science-based risk assessments are rather complex and time-delayed. Although they can lead to important detrimental effects on biodiversity, potential time-delayed disconnections between stakeholders' action and science recommendations are rarely studied. Using the case study of western European beekeepers controlling the invasive Asian hornet Vespa velutina nigrithorax for its suspected impact on honey bee colonies, we analysed mechanisms underlying personal actions of stakeholders and how they evolved in science disconnection. Personal actions of stakeholders were causal-effect linked with their risk observation but disconnected to time-delayed science predictions and recommendations. Unfortunately, these science-disconnected actions also led to dramatic impacts on numerous species of the local entomofauna. These results highlight the need to improve mutual risk communication between science and action in the early-stages of management plans to improve the sustainably of stakeholders' practices. specialized Biological invasion Citizen science Honey bee mortality Invasive species Yellow-legged hornet FRANCE 021 080 098 257 art. 109983 [9 p.] 2020 0301-4797 https://www.documentation.ird.fr/hor/fdi:010078929 10.1016/j.jenvman.2019.109983 0301-4797 [F B010078929] https://www.documentation.ird.fr/hor/fdi:010078929 https://www.documentation.ird.fr/intranet/publi/2020/03/010078929.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2020-05-18 2025-02-24 fdi:010078929 fre
