Parasitism and sex ratio of the bedeguar gall wasp Diplolepis rosae (L.) (Hymenoptera : Cynipidae) in Sicily (Italy)
2006
The Diplolepis rosae gall community is analysed in Sicily (Italy), based on collections totalling 82 galls from 12 sites from which 1,026 adult insects were obtained. The gall wasp exits in March-June from galls induced the previous year. On average 5.6 D. rosae individuals per gall were obtained, corresponding to 44.8% of all the emerged insects. We obtained 4.3% of D. rosae males overall, the highest figure found till now for the cynipid overall in Europe, where male D. rosae are usually rarer, and the first record of them for the Mediterranean area. No inquilines were found, and, consequently, none of their specific parasitoids. However, Eurytoma rosae, generally considered as a specific…

Risk assessment of non-target effects of Closterocerus chamaeleon (Girault) parasitoid of the eucalypt gall maker Ophelimus maskelli (Ashmead) (Hymen…
2015
The pre-release risk assessment, a recommended practice in biological control programmes, was carried out before introducing Closterocerus chamaeleon (Girault), a eulophid parasitoid of the eucalypt gall maker Ophelimus maskelli (Ashmead) (Hymenoptera, Eulophidae), in Sicily, Italy. We evaluated its host specificity in laboratory small arena no-choice tests on six non-target hosts, using O. maskelli as a control species. The non-target species fit with at least one of the following criteria: a) common geographical origin; b) ecological or behavioural affinities with the target host; c) concealed habit of the preimaginal stages; d) taxonomic affinity; e) taxonomic affinity with hosts of cong…

2006
Ophelimus maskelli Ashmead (Hymenoptera, Eulophidae), galligeno sugli eucalipti, è stato accidentalmente introdotto di recente in Italia ed in numerosi paesi del Mediterraneo, causando allarmanti infestazioni, che hanno determinato in taluni casi vistose defogliazioni sulle piante adulte e deperimento delle piantine in vivaio e nei giovani impianti. In considerazione della vastità del patrimonio boschivo siciliano potenzialmente a rischio (25.835 ha, il più esteso d’Italia), è stato avviato un programma di controllo biologico classico, in collaborazione con il Volcani Center (ARO) di Bet Dagan (Israele) e lo CSIRO di Canberra (Australia), mediante l’introduzione del suo parassitoide Closter…

Revision of the European, North-African and Central Asian species of the genus Norbanus Walker 1843 (Hymenoptera: Pteromalidae)
2010
The European, North-African and Central Asian species of the genus Norbanus Walker are revised, providing an illustrated key to males and females of all the species. Three new synonymies are proposed: Norbanus globulariae (Szele´nyi 1941) 5 Norbanus giordanii (Ferrie`re 1952), n. syn.; Norbanus meridionalis (Masi 1922) 5 Norbanus mordellidarum Dzhanokmen 1999, n. syn.; Norbanus obscurus (Masi 1922) 5 Norbanus erdoesi (Szele´nyi 1974), n. syn. Both sexes of N. guyoni are redescribed, and its type locality clarified. A new host record together with distributional data are given for nine out of ten valid species.

Hymenoptera Chalcidoidea inhabiting galls of Cynipidae in Jordan
2008
Twenty-three species of Chalcidoidea (5 Eurytomidae, 4 Torymidae, 2 Ormyridae, 5 Pteromalidae and 7 Eulophidae) are recorded as regular members of the parasitoid fauna inhabiting galls of Cynipidae in Jordan. The occurrence of three additional species, probably only facultatively associated with cynipid galls, is noted. Twenty-two out of the total 26 species were previously unrecorded in the country, while 13 of them are also new for the entire Middle East. Eighteen new host records were detected, together with 24 new plant-parasitoid associations. The biology of each species is briefly commented upon, as well as the presence of a host-related colour variation in some species.

On two Italian Gall Midges (Diptera Cecidomyiidae) and their parasitoids
2016
Some biological data on Cystiphora sonchi (Bremi) and Asphondylia trabuti Marchal in Italy are reported. C. sonchi, previously known only for N Italy, is also recorded for S Italy, Sardinia and Sicily. It induces galls on the leaves of Sonchus spp. (Compositae) all the year around, except for the second half of July and August. The number of galls per leaf was higher in summer (11.6) than in winter (7.4). Overall 5-6 generations per year were observed, with a maximum number of individuals in spring-summer. Larvae often merge in the same gall, pupating inside it and emerging from the lower leaf surface; in winter they can leave galls and pupate outside them. On the whole 426 C. sonchi and 38…

Role of spontaneous plants as a reservoir of alternative hosts for Semielacher petiolatus (Girault) and Citrostichus phyllocnistoides (Narayanan) (Hy…
2006
The role spontaneous plants could eventually play towards populations of two exotic parasitoids, Semielacher petiolatus (Girault) and Citrostichus phyllocnistoides (Narayanan), was investigated in five Sicilian citrus groves. Both species were obtained from two herbs typically living beneath the citrus trees in the period of scarce availability of P. citrella larvae on citrus plants, and precisely: S. petiolatus was reared from Cosmopterix pulcherimella Chambers, leafminer on Parietaria diffusa M. et K., while C. phyllocnistoides on the same species and on a Liriomyza species associated to Mercurialis annua L., these last two host records being new for the parasitoid.

Genetic Variability and Taxonomical Considerations about Six Species of European Cardueline Finches (Aves, Passeriformes)
1997
Abstract Electrophoretic patterns of seven enzyme systems and two nonenzymatic proteins, albumin and haemoglobin, representing 13 loci, have been investigated in six species of cardueline finches with Palearctic distribution. A new locus, SOD-3, has been characterized in this subfamily. The two nonenzymatic proteins turned out to be the best genetic markers. From the analysis of the genetic distances it emerges that the mean values between species are higher than those reported for other groups of birds. However, the same results were obtained for other species of the same subfamily native to North America. In both cases this result is probably due to a classification that disagrees with th…

Le comunità di fillominatori e parassitoidi della Riserva Naturale “Bosco d’Alcamo” (Sicilia)
2015
È stata studiata la comunità di fillominatori e parassitoidi su 16 specie di piante spontanee della Riserva Naturale “Bosco d’Alcamo”. Sono state rinvenute 17 specie di Lepidoptera e 7 specie di Diptera. Da queste sono sfarfallate circa 20 specie di parassitoidi, perlopiù rappresentate da Eulophidae e Braconidae. Viene confermata la presenza in Sicilia del Gracillariidae Phyllonorycter trifasciella Haworth e dell’Eulophidae Derostenus gemmeus Westwood. Per la prima volta Sympiesis notata (Zetterstedt) e Cirrospilus viticola (Rondani) sono stati rinvenuti come parassitoidi di Emme- tia marginea (Haworth). Inoltre S. notata è stata rinvenuta anche come parassitoide di P. trifasciella. Nel com…

Abstract Spread of the exotic parasitoid Closterocerus chamaeleon (Girault) and its parasitism on the Eucalyptus gall wasp Ophelimus maskelli (Ashmead) (Hymenoptera, Eulophidae) were studied in Sicily after C. chamaeleon introduction in May 2006. Parasitoid spread was evaluated by sampling sites at increasing distances from the five release sites. C. chamaeleon quickly established and spread; within 5 months, it caused 62% parasitism at release sites and 38% parasitism at sites 2 km from release sites. One year after its introduction (spring 2007), C. chamaeleon was detected more than 50 km distant from release sites. By winter 2007–08, the parasitoid was recovered throughout Sicily and in …

Ophelimus maskelli, eulofide galligeno di Eucalyptus spp., introdotto in Italia nel 2000, provoca disseccamento e caduta anticipata delle foglie attaccate. Nel 2003 è stato avviato dal Volcani Center (ARO, Israele) e dal CSIRO (Australia) un programma di controllo biologico, introducendo nel 2005 in Israele il parassitoide eulofide Closterocerus chamaeleon (Girault). Nella primavera 2006 l’istituzione israeliana ha inviato al Dip. SENFIMIZO di Palermo foglie di Eucalyptus con migliaia di galle parassitizzate da C. chamaeleon. Dopo i necessari test sulla valutazione del rischio ecologico dell’introduzione, nella prima metà di maggio il parassitoide è stato rilasciato in Sicilia in cinque euc…
NECREMNUS ARTYNES (WALKER) PARASSITOIDE DI TUTA ABSOLUTA (MEYRICK) SU POMODORO, MELANZANA E SOLANUM NIGRUM L. IN SERRA A CONDUZIONE BIOLOGICA
2011
Nel 2010, in serre del palermitano gestite secondo i canoni dell'agricoltura biologica, è stato condotto uno studio volto all'individuazione degli antagonisti naturali indigeni del lepidottero gelechide Tuta absoluta, fitofago esotico dannoso alle solanacee recentemente introdotto in Italia. Le piante campionate sono state il pomodoro, da gennaio a giugno, la melanzana, da fine marzo a giugno, e Solanum nigrum che cresceva spontaneamente all'interno delle serre in piccoli spazi liberi dalle solanacee coltivate. Per tenere sotto controllo il gelechide, il serricoltore ha effettuato tre trattamenti con Bacillus thuringiensis da metà marzo a fine aprile. Oltre al predatore Nesidiocoris tenuis,…
