FAUNA ZLATNIH MARA (COLEOPTERA, CETONIIDAE) I NJIHOVA ŠTETNOST NA PLODOVIMA BRESKVE U VOĆNJACIMA SJEVERNE DALMACIJE, HRVATSKA

The beetles Cetonia aurata and Potosia cuprea belonging to the subfamily CETONIINAE (Coleoptera, CETONIIDAE) are present in peach orchards in Northern Dalmatia, Ravni kotari region. They are often described as flower pest (“Rose chafers, flower beetles”), and are thought not to be significant as fruit pests. However, during the last ten years some serious damage to fruit has been observed. Since this damage occurs when the fruits are ripening, insecticides cannot be used. There are no literature data about the amount of the damage or how to monitor the damage. This paper describes our monitoring of the population dynamics of the Cetonia aurata and Potosia cuprea, and the method for calculating the damage to fruit suitable for the orchards in this area. The study was conducted during the spring and summer of the year 2005, 2006 and 2007 in the Ravni kotari region, near the villages of Prkos and Smilčić. We used Csalomon® VARb3k funnel traps. We took into consideration the population dynamics of the Cetonia aurata and Potosia cuprea, the determination of the other trapped members of the subfamily CETONIINAE, as well as the damage percentage of each cultivar.Kukci Cetonia aurata i Potosia cuprea (zlatne mare) pripadaju potporodici CETONIINAE (Coleoptera, CETONIIDAE), prisutni su u voćnjacima breskve i nektarine na području Ravnih kotara. U literaturi se najčešće opisuju kao štetnici cvijeta, što potvrđuje i naziv na engleskom jeziku (“Rose chafers, flower beetles”), a navodi se da mogu uzrokovati i štete na plodovima, ali bez važnosti. Ipak, tijekom posljednih desetak godina uočeno je da u pojedinim godinama mogu uzrokovati i ozbiljnije štete na plodovima breskve i nektarine. Budući da te štete nastaju u vrijeme dozrijevanja ploda, nikako se ne mogu primijeniti insekticidi. Literatura ne spominje gotovo nikakve podatke o veličini šteta ni o načinu praćenja i izračuna šteta. U ovom istraživanju obuhvatili smo utvrđivanje dinamike populacije zlatnih mara te razvili i u praksi primijenili vlastitu metodiku praćenja i izračuna šteta na plodovima pogodnu za voćnjake ovog područja. Istraživanje je provedeno tijekom proljeća i ljeta 2005., 2006. i 2007. godine na području Ravnih kotara, na lokalitetu Prkos i dijelom na lokalitetu Smilčić. Dinamika populacije zlatnih mara utvrđena je s pomoću lovki s atraktantom Csalomon® VARb3k. U radu je prikazana dinamika populacije vrsta Cetonia aurata i Potosia cuprea, analiza ulova ostalih pripadnika potporodice CETONIINAE te prikaz šteta po sortama

Osservazioni sulla presenza di Eristalinus (Eristalodes) taeniops (Wiedemann, 1818) (Diptera, Syrphidae) in Piemonte (Italia) e nel Canton Ticino (Svizzera)

Remarks on the presence of Eristalinus (Eristalodes) taeniops (Wiedemann, 1818) (Diptera, Syrphidae) in Piedmont (Italy) and Canton Ticino (Switzerland). In this paper, the authors confirm the presence of Eristalinus (Eristalodes) taeniops (Wiedemann, 1818) in some areas of south-central Piedmont (western Italy) and in a locality in Canton Ticino (southern Switzerland). The present contribution reports on occasional findings detected primarily in industrial contexts within the wells of the process water discharge, confirming the ability of this species to grow in organic sludge of various nature. Further investigations may detect a more widespread presence of the species in the northwest of Italy

On nomenclature and identity of Scarabaeus aeruginosus Linnaeus, S. aeruginosus Drury and S. speciosissimus Scopoli (Coleoptera: Scarabaeoidea: Cetoniinae and Rutelinae)

The valid name for the largest European species of Cetoniinae is Protaetia speciosissima (Scopoli, 1786), with Protaetia aeruginosa (Medvedev, 1964) as a junior synonym. The specimen illustrated by Scopoli in the original description is designated as the lectotype of Scarabaeus speciosissimus Scopoli, 1786. Since the lectotype is lost, a neotype from Piedmont, Italy, is designated and deposited in the Museo Civico di Storia Naturale Carmagnola, Italy. The name Scarabaeus aeruginosus Drury, 1773 is unavailable since Drury did not describe a new species but misidentified Scarabaeus aeruginosus Linné, 1767. A specimen figured by Gronovius in 1764 and cited by Linné is designated as the lectotype of Scarabaeus aeruginosus Linné, 1767. This species remains dubious, but it can be assigned to the ruteline subtribe Anticheirina

Nel contempo viene segnalato per la seconda volta, a livello europeo, lo sviluppo della specie a carico di impianti di castagno ibrido giapponese coltivati in coltura specializzata

Human Thelaziasis, Europe

Thelazia callipaeda eyeworm is a nematode transmitted by drosophilid flies to carnivores in Europe. It has also been reported in the Far East in humans. We report T. callipaeda infection in 4 human patients in Italy and France

UPDATING THE TAXONOMY AND DISTRIBUTION OF THE EUROPEAN OSMODERMA, AND STRATEGIES FOR THEIR CONSERVATION (COLEOPTERA, SCARABAEIDAE, CETONIINAE)

Results of a molecular analysis on the European hermit beetles (the Osmoderma eremita species-complex), recently published in a companion paper, are shortly dis- cussed and commented. These results indicate a clear-cut distinction between two clades. The first one includes the W-European O. eremita Scopoli, 1763, and the two Italian endemic taxa O. italicum Sparacio, 2000 and O. cristinae Sparacio, 1994, from southern peninsular Italy and Sicily, respectively. The second one includes the widespread E-European O. barnabita Motschulsky, 1845 (nom. resurr.), and the southern Balcanic O. lassallei Baraud & Tauzin, 1991 from Greece and European Turkey. Within the two clades, molecular data well support a specific rank for O. lassallei and O. barn­abita on one side, and of O. eremita and O. cristinae on the other side, while the taxonomic position of O. italicum, more closely related with O. eremita, is still uncertain, waiting for analysis of additional specimens of this very rare taxon. Current geographical distribution, interspecific genetic diversification, and relatively low levels of intraspecific genetic divergence in O. eremita sensu stricto, are hypothesized to be the result of multiple speciation events (mainly occurred in refugial forest areas of the Italian and Balkan peninsulas and Sicily before and during the Pleistocene glacial peaks), followed by fast post-glacial northward and westward expansion of some species. The need of further genetic data on the rare and threatened hermit beetle species and the importance of more detailed information on their distribution ranges are emphasized and discussed, in order to plan conservation strategies in the near future. An updated worldwide checklist of the species of the genus Osmoderma is finally presented
