Title: Cicadellidae of the forests of Etna (Hemiptera, Homoptera, Auchenorrhyncha) Authors: D'Urso, Vera; Guglielmino, Adalgisa Abstract: The composition of the Cicadellidae fauna of forests of Etna (Italy, Sicily) was studied from a faunistic, ecological and zoogeographical point of view. 107 species of Cicadellidae belonging to 10 sybfamilies were found both on monophytic and poliphytic forests of Etna.

Title: Auchenorrhyncha collected in the Canavese district (Northwest Italy) (Hemiptera, Auchenorrhyncha). Authors: Alma, Alberto; Chen, Ping-Ping; D'Urso, Vera; Guglielmino, Adalgisa; Hollier, John; Kunz, Gernot; Lauterer, Pavel; Malenovský, Igor; Mazzoglio, Peter John; Nickel, Herbert; Nicoli Aldini, Rinaldo; Rintala, Teemu; Seljak, Gabrijel; Seyring, Marcel; Söderman, Guy; Wilson, Michael; Witsack, Werner Abstract: The results of auchenorrhyncha collection excursions in the Canavese district (Italy, Piedmont)are presented, that were held during the 14th Central European Auchenorrhyncha Meeting (07.09.-09.09.2007) and the 4th European Hemiptera Congress (10.09.-14.09.2007) in Ivrea are given. Two new species for Italy, and several new species for Piedmont were found.

Title: The internal male and female reproductive apparatus in Cixidia sikaniae D’Urso & Guglielmino, 1995 (Fulgoromorpha, Achilidae). Authors: D'Urso, Vera; Guglielmino, Adalgisa; Mauceri, Angela Abstract: The morphology of the internal male and female reproductive apparatus in Cixidia sikaniae is described and illustrated. It is compared with the reproductive apparatus of other Achilidae taxa. In the male of C. sikaniae, the structure of the “ejaculatory duct” is peculiar. The presence of lateral ejaculatory ducts, known up to now exclusively in Cicadomorpha, is here described for the first time in a species belonging to the Fulgoromorpha. The phylogenetic value of some characters of the internal male and female reproductive apparatus within Fulgormorpha and between Fulgoromorpha and Cicadomorpha is discussed.

Title: Insecta Hemiptera collected in the Mont Avic Natural Park (Aosta Valley, Northwest Italy). Authors: Alma, Alberto; Bocca, Massimo; Čermak, Václav; Chen, Ping-Ping; D'Urso, Vera; Exnerová, Alice; Goula, Marta; Guglielmino, Adalgisa; Kunz, Gernot; Lauterer, Pavel; Malenovský, Igor; Mazzoglio, Peter John; Nicoli Aldini, Rinaldo; Ouvrard, David; Remane, Reinhard; Rintala, Teemu; Seljak, Gabrijel; Söderman, Guy; Soulier-Perkins, Adéline; Stys, Pavel; Tavella, Luciana; Tedeschi, Rosemarie; Wilson, Mike Abstract: The results are given of the Hemiptera collection exscursions in the Monte Avic Natural Park (Aosta Valley, NW Italy) that took place during the 4th European Hemiptera Congress held in Ivrea in September 2007. Altogether 126 species of Heteroptera, belonging to 89 genera, 108 species of Auchenorrhyncha, belonging to 75 genera, and 30 species of Sternorrhyncha Psyllomorpha, belonging to 8 genera were collected at the four different elevation sites of Capoluogo-Tendeur (500-600m a.s.l.), Chevrère (1200-1400m a.s.l.), Dondena (2100-2300m a.s.l.), and Miserin (2588m a.s.l.). Of these species, 2 were new records for Italy: the Mirid Lygus maritimus and Cicadellid Edwardsiana ishidai. New records for Italy are also the Pipunculid Dipteran Tomosvarjella freidbergi and the Halictophagid Strepsipteran Halictophagus languedoci, parasitoids of Auchenorrhyncha.

Title: Arthropoda di Lampedusa, Linosa e Pantelleria (Canale di Sicilia, Mar Mediterraneo). Homoptera Auchenorrhyncha. Authors: D'Urso, Vera; Guglielmino, Adalgisa Abstract: Vengono censite 47 specie di Auchenorrinchi per Pantelleria e per le isole Pelagie.Tre di esse (Nisia atrovenosa, Hysteropterum algiricum, Hauptidia maroccana) sono nuove per l'Italia. Il popolamento di Auchenorrinchi di quelle isole risulta essere spiccatamente termofilo, con netta prevalenza di specie mediterranee; è inoltre molto più affine al popolamento siciliano che a quello maghrebino.

Title: Considerazioni sulla distribuzione altitudinale dei Cicadellidi sull'Etna (Insecta, Homoptera Auchenorrhyncha). Authors: D'Urso, Vera; Guglielmino, Adalgisa Abstract: The correlations between Etna Cicadellidae peopling and altitude and vegetation belts are here analyzed. Feeding, kind of favourite vegetation and geographic distribution pattern have been examined for each species.Cicadellids of Mount Etna (136 species) colonize any environment up to 2450m. Only seven taxa are present in each of the considered altitudinal belts. The Etna Cicadellids peopling is essentially constituted by a conspicous group of thermophilous species; the most Mediterranean elementa are well represented at every altitude and are particularly numerous between 500 and 1500m. The cool climate elements prefer woody environments between 1000 and 2000m. At high altitude Astragalus and xerophilous grassland are colonized by taxa able to stand great changes of temperature, most of wich live on gramineae.

Some notices about the biology of this species, obtained by laboratory rearing and by observations in the field, are also given.
