Detailed coverage of invasive species threatening livelihoods and the environment worldwide

Abstract

LIFE SAMFIX projet: first results of the forest insect community captured in traps to detect the invasive species Xylosandrus crassiusculus (Coleoptera, Curculionidae, Scolytinae).

Abstract

Xylosandrus crassiusculus is an alien ambrosia beetle species detected for the first time in Iberian Peninsula in 2016, attacking a few carob trees in a residential area of Benifaió, near of Valencia, surrounding of the Parque Natural Munici- pal de El Tello (Llombai). Only attacks on carob trees have been observed, causing death of fine and big branches, and in only a case the entire tree death, although without diminishing their regrowing ability. They are insects with a wide host spectrum: Diospyros kaki Thunb, F icus carica L., Malus domestica (Borkh.) Borkh., Prunus avium (L.) L., Prunus domes- tica L., Prunus persica (L.) Batsch, and the genus Alnus, Quercus, P opulus, Salix, Ulmus, among others. The LIFE SAM- FIX project is aimed to developing collaborative competences and research to develop management protocols and tools for the alien species X. crassiusculus and X. compactus. The project has partners in Italy, France and Spain. The Spanish part- ner is the University of Alicante (Department of Ecology and CBIO Institute), in collaboration with the Forest Planning and Management Service of the Valencian Regional Government. First results of the saproxylic beetle community analyses as- sociated to X. crassiusculus are shown. A highly complex community emerged from our results, composed so far by 40 to 50 species, including xylophagous, floemophagous, native ambrosia beetles, predators, intraguild predators, and other alien species such as Xyleborus ferrugineus.
