La cattura di adulti del Punteruolo rosso delle palme con trappole a feromone e allomoni in ambiente urbano
2010
In questo lavoro sono presentati i risultati di un anno di catture di adulti di Punteruolo rosso delle palme, Rhynchophorus ferrugineus (Olivier), con trappole a feromone e allomoni collocate nel comune di Marsala (TP). In totale sono state sistemate 47 trappole ad una distanza media di circa 200 m. Le trappole sono state innescate con feromone di aggregazione (ferrorule), acetato di etile (10 % /H2O), e melassa (10 % /H2O), ed ispezionate settimanalmente per il periodo aprile 2008 – aprile 2009. Le trappole sono state disposte lungo la costa della città(N=21), e lungo una linea che attraversa il centro cittadino (N=26). In totale sono stati catturati 4010 adulti, con un numero complessivo …
Underestimated impact of Red Palm Weevil introduction on iandscape biodiversity: the help of the molecular tools
2012
Alien species have been introduced both accidentally and intentionally. The last are and have been motivated by economic, environmental and social considerations (NOBANIS, 2010), as in the case of many palm species (Phoenix canariensis, P. dactylifera, Washingtonia filifera, W. robusta) in Sicily. These Arecaceae are important in the urban areas and they contribute to the typical Sicilian Panorama. On the other hand the accidental introduction of invasive alien species can be one a cause of the loss of native biodiversity, especially severe on islands and other isolated ecosystems. Phytophagous insects can cause biodiversity losses and may also have a strong impact on the economy of the isl…
IMPOVERISHMENT OF SICILIAN (ITALY) HISTORICAL AND CULTURAL ASSETS BY AN ALIEN INSECT SPECIES: THE CASE OF THE RED PALM WEEVIL.
2012
Alien invasive species (IAS) have a disastrous impact on the biodiversity, cultural heritage and economy of a geographic area. The case of the Red Palm Weevil (RPW), an IAS that attacks the non-native palm species Phoenix canariensis, but also native species Chaemerops humilis, especially in urban and peri-urban areas, is reported. These palm trees have played an important role in Sicilian history and cultural heritage since the period of the Arab invasion. The accidental introduction of the RPW has remarkably changed the Sicilian panorama. In this study the chronology and the severity of the effects of RPW on palms so far detected, is reported. In only 7 years the RPW has drastically chang…
Fungi related to larvae of red palm weevil Rhynchophorous ferrugineus (Coleoptera: Curculionidae)
2010
As a first step to developing effective biocontrol strategies, we analyzed the pathogens and mainly the entomopathogenic fungal species, present into dead larvae of Rhynchophorous ferrugineus; a quarantine pest recently introduced and acclimated in Sicily (Italy). From 2008 to 2010, we estimated the natural larval mortality (> second instar) of R. ferrugineus collected from infested palm Phoenix canariensis; that was variable from 10 to 35%, according to the different seasons Among the different pathogens recorded the fungi seems have an important role, than in order to distinguish saprophytic or opportunistic species from potential pathogens (including the non cultivable ones) we applied d…
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…
