Abstract

The Asiatic yellow-spotted longicorn beetle, Psacothea hilaris hilaris, was found for the first time in Northern Italy in 2005. As this xylophagous insect is considered one of the most important pests of Morus spp. and of Ficus carica in its countries of origin, a multiyear study was carried out to determine the spread of the pest in Northern Italy, to evaluate its establishment potential and to improve knowledge on its biology in the new habitat. The survey confirmed that P. hilaris hilaris has established in Italy and has colonized an area of about 60 km2. The species overwinters as eggs or larvae. Adults are present from June to October. Damage has been recorded mostly on Ficus carica plants, and very rarely on Morus alba. Both young and older plants, healthy and weakened hosts can be attacked by the pest. Severely attacked plants become weakened and eventually die.
Psacothea hilaris hilaris, (capricorne asiatique a taches jaunes) a ete identifie en Italie septentrionale pour la premiere fois en 2005. Puisque cet insecte xylophage est considere comme un des ravageurs les plus importants de Morus spp. et de Ficus carica dans sa zone d’origine, une etude pluriannuelle a ete entreprise pour determiner la dissemination de cet organisme nuisible dans le nord de l’Italie, determiner son potentiel d’etablissement, et ameliorer les connaissances sur sa biologie dans ce nouvel habitat. Les resultats confirment que P. hilaris hilaris s’est etabli en Italie et a colonise une zone d’environ 60 km². Cette espece passe l’hiver sous forme d’oeuf ou de larve. Les adultes sont presents de juin a octobre. Les degats ont principalement ete observes sur des Ficus carica, et tres rarement sur Morus alba. Le ravageur attaque aussi bien les plantes jeunes qu’agees, saines que malades. Les plantes severement atteintes sont affaiblies, et finissent par mourir.
