Another chapter in the history of the European invasion by the Western conifer ...
Farinha, Ana Oliveira; Branco, Manuela; Courtin, Claudine; Lesieur, Vincent; Gallego, Diego; Sanchez-Garcia, Francisco Javier; Sousa, EdmundoThe Western conifer seed bug, Leptoglossus occidentalis, is native to North America and has already been considered a significant pest in several European countries since its first observation in Italy in 1999. In Spain and Portugal, it was recorded for the first time in 2003 and 2010, respectively, and its impact on Stone Pine (Pinus pinea) is of major concern. Before developing control measures for this insec...
Urban trees facilitate the establishement of non-native forest insects
Branco, Manuela; Nunes, Pedro; Roques, Alain; Fernandes, Maria Rosário; Orazio, Christophe; Jactel, HervéCities, due to the presence of ports and airports and the high diversity of trees in streets, parks, and gardens, may play an important role for the introduction of invasive forest pests. We hypothesize that areas of urban forest facilitate the establishment of non-native forest pests. Based on scientific literature and a pan-European database on non-native species feeding on woody plants, we analysed where the...
The stone pine, Pinus pinea L., a new highly rewarding host for the invasive Le...
Farinha, Ana O.; Durpoix, Charlene; Valente, Susana; Sousa, Edmundo; Roques, Alain; Branco, ManuelaThe invasive seed bug Leptoglossus occidentalis, a species native to Western North America, is of major concern for the producers of stone pine seeds in the Mediterranean countries. The large size of these edible seeds and their nutritive content may represent a pull factor for the seed bug. Cone and seed traits of three main Mediterranean pine species: P. pinea, P. pinaster, and P. halepensis, were evaluated. ...
