Discovery of Xylella fastidiosa from olive trees with "Olive quick decline syndrome" in October 2013 on the west coast of the Salento Peninsula prompted an immediate search for insect vectors of the bacterium. The dominant xylem-fluid feeding hemipteran collected in olive orchards during a 3-mo survey was the meadow spittlebug, Philaenus spumarius (L.)(More)
Two young children, respectively 11 and 13 years old, originally from a small town of Southern Italy, were missing on 5 June 2006 (06:30 p.m.). Soon after their disappearance, the search for the missing children began. Broadcasters promptly transmitted a description of the missing children, pushing the entire community to assist in the search and safe(More)
In June, 2006, a 32 year-old woman, working as an architect at the archaeological site of Pompeii, noticed that her nose was blocked, especially the right nostril. When she blew her nose, the mucus was black. A few days later, she developed a dry cough, and intermittent fever. Her general practitioner referred her to an otolaryngologist. Nasal examination(More)
This paper evaluates the effect of two policy changes on the efficiency of Italian regional governments in the provision of health care services: first a change in the electoral system; second a process of fiscal decentralisation. The electoral system was changed in 1995 and replaced a pure proportional system by a majoritarian system, fostering the(More)
This contribution focuses on recent interceptions and introductions of alien scale insects and their current distribution in European and Mediterranean countries. Data and collections were gathered in markets, nurseries, and botanical gardens, mostly in Italy, either indoors or outdoors. New or recent records of the following alien species are presented:(More)
The use of Comprehensive Performance Assessment (CPA) to monitor the performance of 148 English local authorities (unitary and two-tier) between 2002 and 2008, and reward good performers with lower central intervention was a unique policy experiment. Taking advantage from the English assessment procedure this paper studies, both theoretically and(More)
To characterize red pigment-producing bacteria (RPPB) regularly released during oviposition by red palm weevil (RPW), RPPB were recovered from eggs deposited in apples supplied as substrate for oviposition. The presence of RPPB was also detected from gut, the reproductive apparatus of dissected adult and virgin insects and from pupal cases collected within(More)
The recent introduction of Xylella fastidiosa in Europe and its involvement in the Olive Quick Decline Syndrome (OQDS) in Apulia (Salento, Lecce district, South Italy) led us to investigate the biology and transmission ability of the meadow spittlebug, Philaenus spumarius, which was recently demonstrated to transmit X. fastidiosa to periwinkle plants.
