Impoverishment of Sicilian (Italy) historical and cultural assets by an alien insect species:the case study of the Real Palm Weevil
2012
Microorganisms and insects have a disastrous impact on the biodiversity, cultural heritage and economy of a geographic area. However, in recent decades, the negative effects of invasive alien species (IAS), including both animal and plant or microorganisms occurring outside their natural distribution range, are generally not well known. Invasive alien species are most often found in or near urban areas, as well as throughout the settled landscape. According to the World Conservation Union, IUCN 2012, IAS represent the second most significant threat to biodiversity after resource depletion of habitats, becoming predators, competitors, parasites, hybridizers and diseases for native plants and…
Stratégies de lutte contre le charançon rouge du palmier
2018
La communauté scientifique internationale (source : publication FAO d’avril 2017) s’accorde sur l’importance de la combinaison des mesures de lutte en fonction des niveaux d’infestation par le charançon rouge du palmier. Plusieurs mesures de lutte sont disponibles ou envisageables : assainissement mécanique, application d’insecticides à titre préventif ou curatif, piégeage de masse et biocontrôle (lutte biologique sensu stricto). Il est à noter que plusieurs expérimentations sur le biocontrôle sont en cours.Dans la perspective d’améliorer les stratégies de lutte contre le charançon rouge du palmier, il est demandé : 1) d’identifier les stratégies de lutte (en tant que combinaison de différe…
First Report of Bud Rot of Canary Island Date Palm Caused by Phytophthora palmivora in Italy.
2007
Canary Island date palm (Phoenix canariensis hort. ex Chabaud) is planted as an ornamental in Mediterranean climatic regions of the world. From 2004 to 2006, withering of the spear leaf was observed on screenhouse-grown potted plants of this palm in Sicily (Italy). The first symptom was a dark brown rot that extended from the petiole base of the spear to the adjacent youngest leaves and killed the bud. Dissection of plants revealed a foul-smelling internal rot. After the bud died, external older leaves remained green for months. As much as 10% of plants in a single nursery were affected. A Phytophthora species was consistently isolated from symptomatic plants on BNPRAH selective medium (4)…
