“…Several regions in Europe are recently colonised by the exotic ragweed leaf beetle Ophraella communa LeSage . This leaf feeder preferably feeds on A. artemisiifolia and has the potential to reduce its growth and reproduction (Zhou et al 2014), and is a candidate biological control agent of A. artemisiifolia in Europe (Lommen et al 2017). We expected negative effects of this beetle on the performance of A. artemisiifolia and assessed its presence at the sites.…”

“…1 Location of the 39 study sites used for the analyses, with symbols according to the habitat type (AR arable, GR grassland, IN infrastructure, RU ruderal). Areas shaded in blue indicate areas known to be heavily colonized by A. artemisiifolia (numerous and abundant stands) and with high levels of allergies and/or damage to agriculture (based on Chapman et al 2016;Déchamp et al 2009;Essl et al 2015), while the red oval connected to the picture of the ragweed leaf beetle Ophraella communa indicates the area colonized by this candidate biocontrol agent (based on Lommen et al 2017) to assess site-specific conditions, we selected sites without clear environmental gradients. We aimed to cover the most important habitat types of A. artemisiifolia.…”

“…It was first recorded in Europe in 2013, when the species was found in northern Italy (Lombardy, Piedmont and Emilia-Romagna regions) and in southern Switzerland (Ticino Canton; Bosio et al 2014, Müller-Schärer et al 2014). Due to its high dispersal ability (potentially up to 329 km/year; Yamamura et al 2007), it was expected to rapidly expand its European range and, by 2013, was already covering an area of 20000 km 2 (Müller-Schärer et al 2014, Lommen et al 2017b. O. communa larvae and adults preferentially feed on A. artemisiifolia and they can completely defoliate the plant to death prior to seed production when the initial density is high enough , Zhou et al 2014.…”

“…Palmer and Goeden (1991) rejected the beetle as a biocontroller for Australia because, in laboratory tests, it can complete its life cycle on sunflower while, recently, the possibility of an Ophraella's attack on H. annuus in the field was considered negligible (Dernovici et al 2006, Cao et al 2011. Most of the studies on the potential ability of O. communa to choose new host plants in introduced areas were conducted on weeds or species of commercial interest (Palmer and Goeden 1991, Watanabe and Hirai 2004, Dernovici et al 2006, Cao et al 2011, Lommen et al 2017b. The risk to native flora was rarely taken into account.…”

“…23) Assessments of its potential impact in Europe have been prioritized. 24) It is unknown how insecticides affect common ragweed performance or the allergenicity of its pollen. The allergenicity of pollen of this species is known to be altered by other abiotic stressors, such as drought, aerial pollutants and elevated levels of CO 2 , NO 2 and O 3 .…”
