Popillia japonica (Pj) is a pest insect native to Japan that was recently introduced into Europe. In Switzerland, it is established in parts of the Cantons of Ticino and Valais, and present around Zurich International Airport and in Basel. Given Pj’s wide spectrum of host plant species and its likely nega-tive impacts on agriculture and ecosystem services, research on Pj is critical for supporting eradica-tion, containment and management. With PUPILLA, we aim at (i) better understanding the ecology of Pj, including habitat, host plant and oviposition site preferences, as well as landscape features that drive its spread and colonization; (ii) developing and testing tools based on eDNA techniques for early detection and more targeted surveillance; (iii) developing control strategies in the vineyard agroeco-system based on attract-and-kill approaches, which may potentially be transferred to other cropping systems. The research activities will be conducted in the infested zones of the Cantons of Ticino and Valais.
PUPILLA will support the authorities in the decision-making and the Plant Protection Services by providing surveillance tools and critical information on Pj ecology. The development of control strate-gies will be crucial to ensure environmental resilience and sustainable crop production, benefitting all actors in the agricultural sector.
