A plea for using the correct taxon names of phytoplasma vectors: a case of Reptalus artemisiae, a vector of 'Candidatus Phytoplasma solani'

The planthopper Reptalus artemisiae (Becker, 1865) (Hemiptera: Cixiidae) is an emerging vector of 'Ca. Phytoplasma solani', and a well studied species for nearly two decades for its tentative, and later proven, vector role in phytoplasma transmission (Trivellone et al., 2005; Chuche et al., 2016). However, until recently, there was a misidentification of this taxon, leading to the incorrect nomenclature of Reptalus quinquecostatus (Dufour, 1833) (Webb et al., 2013), which is actually the name of another cixiidae species, previously known as Reptalus melanochaetus (Fieber, 1872) and now considered as its junior synonym. The case of misidentification was presented and documented in detail by Webb and coauthors (2013), while the question of naming Reptalus quinquecostatus sensu Fieber was resolved by Emeljanov (2020), who made the necessary nomenclatural changes. The changes were made following the International Code of Zoological Nomenclature, Article 70.3. We present here an overview of the (in)correct use of the taxon names for the two species in the last three years since the changes were made and make a plea for using the correct taxon names

Rasprostranjenje alder yellows fitoplazme na crnoj i beloj jovi (Alnus glutinosa i Alnus incana) u Srbiji

Alder yellows (AldY) phytoplasma associated with common alder (Alnus glutinosa) and grey alder (A. incana) belongs to the ribosomal RNA group16SrV. This phytoplasma is closely related to the Flavescence dorée (FD) phytoplasma, a quarantine pathogen of economic importance that affects vineyards of southern Europe including Serbia. To date, alder yellows phytoplasma has been reported in many European countries including France, Germany, Switzerland, Austria, Italy and the Baltic region. Infected alders are exhibiting symptoms such as leaf yellowing, small leaves, reduced foliage, or sometimes they remain symptomless. To investigate occurrence and distribution of this phytoplasma, a survey was conducted on a wide territory of Serbia. Results confirmed wide distribution of alder yellows phytoplasma in Serbia in both symptomatic and asymptomatic trees. From the 72 plants sampled, 54 were positive for the presence of phytoplasmas. RFLP profiles of the 16S rRNA gene indicated presence of 16SrV-C phytoplasma subgroup. Further characterization by PCR-RFLP analysis of the ribosomal protein gene operon of all phytoplasma positive isolates tested confirmed presence of the 16SrV-C phytoplasma subgroup. Implication of the wide distribution of AldY phytoplasma to the epidemiology of FD phytoplasma as well as disease management are discussed.Alder yellows (AldY) fitoplazma koja je u asocijaciji sa crnom jovom (Alnus glutinosa) i belom jovom (A. incana) pripada 16SrV ribozomalnoj grupi fitoplazmi. Ova fitoplazma je srodna fitoplazmi zlatastog žutila vinove loze Flavescence dorée (FD), koja je karantinski patogen od ekonomskog značaja u vinogradima južne Evrope uključujući i Srbiju. Do sada je prisustvo alder yellows fitoplazme utvrđeno u mnogim evropskim zemljama uključujući Francusku, Nemačku, Švajcarsku, Austriju, Italiju i Baltički region. Inficirane jove ispoljavaju simptome žutila listova, malih listova, redukcije lisne mase, ili ponekad ne ispoljavaju simptome inficiranosti. U cilju utvrđivanja prisustva i rasprostranjenja ove fitoplazme na široj teritoriji Srbije, sprovedeno je uzorkovanje simptomatskih i asimptomatskih jova. Rezultati istraživanja su potvrdili široku distribuciju alder yellows fitoplazme u Srbiji i prisustvo fitoplazme kako u simptomatskim tako i u asimptomatskim stablima. Od ukupno 72 uzorkovane biljke, 54 su bile inficirane fitoplazmom. Analizom RFLP profila 16S rRNK gena utvrđeno je prisustvo 16SrV-C podgrupe fitoplazmi. Dalja karakterizacija PCR-RFLP analizom operona ribozomalnih proteina svih pozitivnih izolata potvrdila je prisustvo 16SrV-C podgrupe fitoplazmi. U diskusiji je istaknut značaj širokog rasprostranjenja AldY fitoplazme i uticaja na epidemiologiju FD fitoplazme kao i na kontrolu bolesti

Tuta absoluta (Meyrick, 1917) (Lepidoptera, Gelechiidae) - nova štetočina paradajza u Srbiji

Tomato leaf miner Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), a devastating pest of tomato originating from South America has been recorded in Serbia on three localities: in tomato main greenhouse and open field production area located in the vicinity of town Leskovac (South Serbia), in surroundings of the village Donji Vrtogoš (near town Vranje, South Serbia) and in a greenhouses complex in Kraljevci (60 km west of Belgrade). The presence of T. absoluta was confirmed by morphological and molecular study of the collected specimens.Prisustvo lisnog minera paradajza Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), opasne štetočine poreklom iz Južne Amerike, utvrđeno je na tri lokaliteta u Srbiji: u plastenicima i poljima u okolini Leskovca (južna Srbija), u okolini sela Donji Vrtogoš (u blizini Vranja) i u kompleksu plastenika u selu Kraljevci (60 km zapadno od Beograda). Identifikacija T. absoluta je izvršena morfološkim i molekularnim analizama sakupljenih uzoraka

Description of immature stages of Rhinusa species (Coleoptera, Curculionidae, Mecinini) with a focus on diagnostic morphological characters at the species and genus levels

The mature larvae of the following fourteen Rhinusa species are described and illustrated: Rhinusa antirrhini (Paykull, 1800), R. asellus (Gravenhorst, 1807), R. collina (Gyllenhal, 1813), R. eversmanni (Rosenschoeld, 1838), R. florum (Rubsaamen, 1895), R. herbarum (H. Brisout de Barneville, 1862), R. incana (Kirsch, 1881), R. linariae (Panzer, 1796), R. melas (Boheman, 1838), R. neta (Germar, 1821), R. pilosa (Gyllenhal, 1838), R. rara Toševski & Caldara, 2015, R. tetra (Fabricius, 1792), and R. vestita (Germar, 1821). The pupae of thirteen of them (except R. incana) were also described. The comparison of larval morphological characters and plant preferences provides evidence supporting the existence of different species groups previously established according to a phylogenetic analysis based on adult morphological characters. The following diagnostic attributes distinguishing the genus Rhinusa are highlighted. For the larvae: (1) pronotal shield indistinct; (2) thoracic prodorsal fold small or even vestigial; (3) abdominal postdorsal folds (especially of segments III–VII) high or even in the form of conical protuberances; (4) cuticle of abdominal segments densely covered with asperities; (5) cuticle without dark spots or dark pigmentation; (6) head suboval, rarely round; (7) labrum usually with 2 als; (8) des1 short or absent, rarely elongated; and (9) fs1-3 usually absent or minute. For the pupae: (1) body stout; (2) head protuberances always present; (3) pronotal protuberances (if present), separated at bases of the pronotum, always wider than higher; (4) abdominal protuberance usually present, wide or round; (5) femora usually with a single fes; and (6) urogomphi short or vestigial. Keys to the larvae and pupae described here are provided. All the characters used for identification are illustrated by photographs or drawings. Biological and distribution data, including new information, are provided for all the species studied
