First Report of Leaf Spot and Blight Caused by Ralstonia pickettii on Bird of Paradise Tree in Italy
2008
Bird of Paradise tree (Strelitzia alba (L. f.) Skeels) is an ornamental perennial tropical plant grown in southern Italy. In the summer of 2006 and 2007, a widespread, severe leaf disease was observed on seedlings and 1- to 2-year-old plants in two glasshouses located in eastern Sicily. Disease incidence ranged from 10 to 25%. Symptoms on the leaves consisted of dark brown-to-black stripes of varying length and found between the lateral veins. Lesions sometimes coalesced into a large area of necrotic tissue. Symptomatic tissues were ground in a drop of sterile distilled water (SDW) with a scalpel. Suspensions were streaked on King's medium B (KB), nutrient agar, and yeast extract nutrient …
On the real identity of the Strelitzia cultivated in Sicily’s historic gardens
2016
The authors, on the basis of field observations and literature search, conclude that all tree-like plants of Strelitzia grown in Sicily belong to Strelitzia nicolaii. Therefore Strelitzia alba (= Strelitzia augusta), which was generally considered to be commonly cultivated in Sicily since the nineteenth century, if it ever was cultivated on the island, is not currently found there. The Lectotypes of the names S. nicolaii and S. alba are here designated.
Strelitzia nicolai (Strelitziaceae), new host plant for Rhynchophorus ferrugineus (Coleoptera Curculionidae) in Sicily.
2015
The Red Palm Weevil Rhynchophorus ferrugineus (Olivier, 1790) (Coleoptera Curculionidae), is con- sidered the main palm pest in the Mediterranean basin. This species is native to Southeastern Asia and is now widely spread throughout Oceania, Africa, Europe and the Caribbean (MURPHY & BRISCOE, 1999; EPPO, 2008, 2012; CHEBBI et al., 2011; RODA et al., 2011). Moreover, in North America the pest was found in California, where it is now considered eradicated (CDFA, 2010; IPPC, 2015). In Italy the first registered sightings were on nursery palms in Tuscany (SACCHETTI et al., 2005, 2006) and on ornamental palms in urban areas in Sicily (LONGO & TAMBURINO, 2005; LO VERDE & MASSA, 2007).
