THE RED PALM WEEVIL IN SICILY: THE INTRODUCTION AND SPREAD OF AN INVASIVE ALIEN SPECIES
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 …
Attacks of Rhynchophorus ferrugineus on natural specimens of dwarf fan palm Chamaerops humilis in Sicily.
The red palm weevil Rhynchophorus ferrugineus was recently introduced into Europe where it has destroyed many Phoenix canariensis palms. This weevil attacks different species of palms in different countries, mainly cultivated date palms (Phoenix dactylifera) in Egypt and cultivated Canary palms (Phoenix canariensis) in Europe. In Europe, sporadic attacks of the weevil to native dwarf fan palm (Chamaerops humilis) have been reported. The current paper reports attacks of R. ferrugineus on dwarf fan palms in natural environments of Sicily. This insect represents an important threat to dwarf palms and to the complex ecosystem where they live.
