THE RED PALM WEEVIL IN SICILY: THE INTRODUCTION AND SPREAD OF AN INVASIVE ALIEN SPECIES
2013
The red palm weevil (RPW), Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae), is a pest from Southeast Asia accidentally introduced into North Africa and Europe two decades ago. In Sicily, RPW was recorded for the first time in 2005, then, in few years, it established becoming the most severe pest of ornamental palm species in urban, monumental and country areas. In this paper, we first report the history of its introduction and spread. Then, we reviewed the preventative and curative strategies that have been implemented with variable degrees of success in containing the invasive alien pest. Finally, we focus on the development of new strategies to detect early infestations and …

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…
La localizzazione dell’ospite nei parassitoidi oofagi: il ruolo delle cere epicuticolari delle piante
2009
La localizzazione dell’ospite nei parassitoidi oofagi è il risultato di un complesso comportamento di foraggiamento influenzato prevalentemente da stimoli di natura fisica e chimica. I segnali chimici (semiochimici) possono derivare dall’interazione tra la pianta e l’uovo ospite (sinomoni indotti dall’ovideposizione), dall’uovo tal quale (cairomoni diretti) e/o da stadi diversi da quello di uovo, come per esempio l’adulto (cairomoni indiretti). I sinomoni indotti con l’ovideposizione, capaci di richiamare i parassitoidi delle uova ancor prima che il fitofago possa causare danni, sono un efficace esempio del coinvolgimento “diretto” della pianta nel processo di localizzazione dell’ospite da …
FACCOLI M., 2015. Scolitidi d’Europa: tipi, caratteristiche e riconoscimento dei sistemi riproduttivi. Ed. WBA Handbooks 5, Verona. 160 pp., € 25,00
2017
Il volume di Massimo Faccoli presenta le principali specie di Scolitidi europei attraverso la descrizione e la classificazione dei loro sistemi riproduttivi, termine con cui si indicano i sistemi di gallerie scavate dalle femmine adulte e dalle larve, le cui caratteristiche consentono in molti casi di risalire alla specie che le ha tracciate.

The Embioptera from the Strait of Sicily Islands: first records from Pantelleria and Lampedusa and new data from Lampione (Sicily, Italy)
2021
The occurrence of Embioptera in the Strait of Sicily islands was up to date known only from Lam pione (the smallest of the Pelagie islands), where the only species reported was provisionally assigned to Embia ramburi Rimski-Korsakow, 1905. Based on material recently collected by the authors, the presence of Embioptera is here reported for the first time in the Islands of Pantelleria (Sicily, Trapani) and Lampedusa (Sicily, Agrigento). In the Island of Pantelleria the occurrence of the typical small silky tunnels produced by Embioptera has been verified in many sites, from sea level to Montagna Grande (836 m). In many of these sites, several juveniles and some adult or subadult specimens wer…
SICILY AS THEORETICAL MODEL TO STUDY THE POTENTIAL IMPACT OF GENETICALLY MODIFIED PLANTS IN A HOTSPOTS OF BIODIVERSITY
2015
In Europe, especially in Italy, different considerations are necessary when potential GMPs are to be grown. In particular high biodiversity areas such as Sicily should have a more detail plans of potential benefits and risks assuring the conservation of biodiversity and endemic species. Sicily is one of the most relevant biodiversity hotspots in the Mediterranean area, with a vascular flora of 3252 species and 321 endemic taxa. Considering the latest IUCN categories and criteria, 401 taxa (12.4% of Sicilian flora) are under threat (categories “CR”, “EN”, “VU”), and 220 more taxa (6.8%) are “Near Threatened”. Sicily is also known to have a rich butterfly and coleopteran fauna including endem…
