m LJUBLJANA, JULIJ 2006 Vol. 14, ot. 1: 11-34 ACTA ENTOMOLOGICA SLOVENICA AN OVERVIEW OF THE CURRENT KNOWLEDGE OF JUMPING PLANT-LICE OF SLOVENIA (HEMIPTERA: PSYLLOIDEA) Gabrijel Seljak Kmetijsko gozdarski zavod Nova Gorica, Pri hrastu 18, 5000 Nova Gorica, Slovenia Abstract - A list of the jumping plant-lice (Psylloidea) species recorded in Slovenia is given: 100 species have been found of which 44 are new to the Slovenian fauna. The records of Trioza kiefferi Giard were based on misidentification, and the species is considered as absent from Slovenia. Key words: Hemiptera, Psylloidea, fauna, Slovenia Izvleoek - PREGLED TRENUTNEGA POZNAVANJA BOLOIC SLOVENIJE (HEMIPTERA: PSYLLOIDEA) Predstavljen je pregleden seznam boloic (Psylloidea), ki so bile doslej ugotovljene na ozemlju Slovenije. Seznam vsebuje stare zapise in nove podatke za 100 vrst. Od teh je 44 novih za favno Slovenije. Stari podatki za vrsto Trioza kiefferi Giard temeljijo na napaoni dolooitvi, zato je vrsta izlooena iz seznama. Kljuone besede: Hemiptera, Psylloidea, favna, Slovenija Introduction Psyllids or jumping plant-lice are very small insects whose size in European species usually varies from 1,5 to 4,5 mm in length. They are exclusively phytophagous sap-sucking insects (Ossiannilsson, 1992). In general, they are highly host specific and are mostly associated with only one single plant species or with a very restricted number of closely related host plants. There are very few European species which can be characterized as polyphagous (e.g. Bactericera nigricornis). From this point of view, it is possible to predict the occurrence of the associated psyllid species based on the distribution data of their host plants. Some psyllids are also known as serious pests of cultivated plants - e.g. Cacopsylla pyri (Pollini, 1998; 11 Acta entomologica slovenica, 14 (1), 2006 Vrabl & Matis, 1977), C. pyrisuga (Pollini, 1998, Janeaio, 1951), Cacopsylla mali (Janeaio, 1951), Acizzia jamatonica (Alma & al., 2002, Seljak & al., 2004), Euphyllura olivina (Pollini; 1998, Chermiti, 1992). Some of them are known to be important vectors of harmful phytoplasma diseases of crop plants - e.g. Cacopsylla pyri (Lemoine, 1991, Carraro & al. 1998a), C. pyricola (Jensen & al., 1964), C. pruni (Carraro & al., 1998b, Jarausch, 2001), C. melanoneura (Tedeschi & Alma, 2004), C. picta (Frisinghelli & al., 2000; Jarausch & al. 2003). As long ago as 1888 Franz Löw made the most comprehensive overview of psyllids occurring in the territory of the former Austrian-Hungarian monarchy, which includes also the territory of the present Slovenia (Löw, 1888). This remains until now the only specialized work dealing with psyllids in the territory of Slovenia. In that work, 37 species belonging to the family Psyllidae and 14 species of Triozidae, collected within the Slovene territory are recorded. Most of the data Löw included were provided by Franz Then, who collected psyllids in the surroundings of Lesce (Less) and Bled (Valdes) and by Andor Hensch, who worked and collected in the surroundings of Gorica (Görz, Gorizia). The type material of at least three species originates from these two collecting areas. The type material Fig. 1: Camarotoscena subrubescens – adult. Fig. 3: Cacopsylla pyrisuga - nymphs visited by ants. Fig. 2: Acizzia jamatonica - two adults and a nymph sucking on leaf of Albizia julbrissin. Fig. 4: Trioza alacris - gall on Laurus nobilis leaf caused by nymphs. 12 Gabrijel Seljak: An overview of the current knowledge of jumping plant-lice of Slovenia (Hemiptera: Psylloidea) of Psyllopsis meliphila Löw, 1881 originate unambiguously from the territory of Slovenia (Lesce, Bled), while the type locality “Görz” for Baeopelma colorata (Löw, 1888) and Cacopsylla intermedia (Löw, 1888) is problematic, because the region is divided between Slovenia and Italy at present. Officially, Italy is “terra typica”, but the type material was quite probably collected on the Slovene side as well. Gräffe (1911) also contributed some faunistic records, which mostly refer to the area round Tolmin. Almost exactly hundred years later Franc Janeaio summarized his seventeen years’ investigations on plant galls of Slovenia, also providing a large amount of distribution data concerning 25 species of Psylloidea (Janeaio, 1989). Some of his records require a confirmation or even revision according to the modern taxonomic view. However, as his identifications were based mainly on the host plant and the gall form only and as far as I know, no documentary collection is available, it is almost impossible to confirm his records with reference to the more critical species. There are also some other reports dealing with pear psyllids (e.g. Cacopsylla pyri, C. pyrisuga) in Slovenia, but mainly only from the agricultural point of view (Vrabl & Matis, 1977). Knowledge of the diversity of psyllids and their distribution in Slovenia is still incomplete and in general poorly investigated. The intention of this overview is to summarize and confirm records of psyllids previously known to occur in Slovenia. In addition, my own data gathered in the last few years have been included. Methods Faunistic investigations by the author on the psyllids of Slovenia have been carried out in the past five years. Material has mainly been collected intentionally, by looking for adults and the fifth instar nymphs on their host or shelter plants, but partly also unintentionally during collecting trips of plant- and leafhoppers. Sweep-netting and beating methods were mainly used to obtain adults from the host or shelter plants. Nymphs were collected together with their host plants in small plastic bags or picked up and preserved in 70 % ethanol in plastic tubes. For the identification following work were mostly used: Ossiannilsson, 1992; Hodkinson & White, 1979; White & Hodkinson, 1982; Hodkinson & Hollis, 1987, Loginova, 1964; Klimaszewski, 1975; Haupt, 1935. Adults were dry mounted on specimen cards and are included in the author’s collection. Fifth instar nymphs and sometimes younger nymphs were slide-mounted in Canada balsam as described by Hodkinson & White (1979). For an accurate identification, a stereomicroscope (Nikon SMZ-2B) and a compound microscope (Nikon Labophot-2) were applied. In the table below data on Psylloidea hitherto known to occur in Slovenia are summarized. For each species the earlier records and their authors (Scopoli, 1763; Löw, 1888; Gräffe, 1911; Janeaio, 1989) are given. New distribution data provided by myself are given separately. For each species, the larval host plant(s) are listed as 13 Acta entomologica slovenica, 14 (1), 2006 Fig. 5: UTM grid of Slovenia and distribution of Diaphorina chobauti Puton as an example. well. As it has been impossible to examine the original material of earlier collectors (e. g. Then, Hensch, Löw), the older published data have been interpreted in the modern taxonomic view only when they have already been clarified by modern authors. When the locality was defined well enough, the corresponding 10x10-kilometre UTM quadrant has also been added (fig. 5). As the whole territory of Slovenia goes into the grid zone 33T, the zone designation of UTM quadrants is omitted. Records referring to Görz (Gorica or Gorizia, Italy) by Löw (1888) are also included, because a considerable part of Hensch’s collecting area around this border town belongs to the present Western Slovenia. This area includes at least the following UTM quadrants: UL89, UL98, UL99, VL08, and VL09. The taxonomy and nomenclature of Psylloidea follows Burckhardt (2002). The nomenclature source for the names of vascular host plants was “Mala flora Slovenije” (Martinoio & al, 1999). The host plant range for individual psyllid species were mostly taken from Ossiannilsson (1992), White & Hodkinson (1982), Conci, Rapisarda & Tamanini, 1992 and 1997 or Burckhardt (2002), but also some data based on my own observations were used. 14 Gabrijel Seljak: An overview of the current knowledge of jumping plant-lice of Slovenia (Hemiptera: Psylloidea) Abbreviations GS: previously unpublished data; material collected and examined by the author.

HP: Galium spp. (Rubiaceae) Comments on some critical or less known species Camarotoscena speciosa (Flor, 1861) and C. subrubescens (Flor, 1861) According to Conci & al. (1993) the distribution of Camaratoscena subrubescens is limited to warm regions of the Mediterranean northern side. It is recorded from 28 Gabrijel Seljak: An overview of the current knowledge of jumping plant-lice of Slovenia (Hemiptera: Psylloidea) Spain, France, Italy (including Sicily), east Adriatic countries, Greece and Turkey. Also in Slovenia, its occurrence seems to be confined to the south-western submediterranean part of the country. Some records concerning Camarotoscena speciosa given by Janeaio most probably refer to C. subrubescens or at least those originating from South-Western Slovenia (e. g.: Solkan, Skalnica, Grgar, Neblo, Preonica, Dekani, Bertoki, Omarje pri Kopru, Dragonja). This is because his identifications were based on gall characters only and not on adults or fifth instar nymphs. Specimens collected in this area by myself (although the material is still quite scarce), as well as the material collected by A. Hensch in the surrounding of Gorica (Löw, 1888), support this uncertainty representing C. subrubescens only. Anyway, records given by Janeaio are in need of further faunistic verification. Until now, I also could not find both species together, although they use the same host species. Aphalara calthae (Linnaeus, 1761) According to Lauterer (1993) older records of Aphalara calthae published 40 years or more ago need to be verified, as species of the group Aphalara polygoni Förster were often published under this name as well. Recently collected material on Pokljuka confirms however unambiguously the occurrence of Aphalara calthae in Slovenia. Rhodochlanis bicolor (Scott, 1880) This species is recorded from South Russia, Ukraine, Kazakhstan (Loginova, 1964, Gegechkori & Loginova, 1990) and Bulgaria (Klimaszewski, 1973). It is known to occur in Iran as well (Burckhardt & Lauterer, 1993), but seems to be rather rare in the Mediterranean basin or perhaps merely less investigated. Conci and Tamanini recorded it from a comparatively restricted coastal area near to Ravenna (Conci & Tamanini, 1984). In Slovenia, it is only known from the two above-mentioned localities on the saline vegetation close to the Adriatic Sea. Suaeda maritima was confirmed as the host plant, on which also some few nymphs of fourth and fifth instars were found. Many adults and some nymphs were also collected near Poreo in Istria (Croatia) in late August 2005, always on the same host plant. These findings are obviously only a part of the larger, but still poorly investigated north-Adriatic population of Rhodochlanis bicolor. Psyllopsis fraxini (Linnaeus, 1758) Quite probably, Psyllopsis fraxini is widely spread throughout the whole country on its host plant Fraxinus excelsior. However, data given by Janeaio (1989) based on the presence of galls are not unambiguous, because identical galls cause P. distinguenda Edwards, P. discrepans (Flor) and P. dobreanuae Loginova as well. P. fraxini is the most common species and plausible one. Psyllopsis meliphila Löw, 1881 In Slovenia, in particular in its western part, this species is widely spread on its host plant Fraxinus ornus in temperate slopes. According to my observations, it develops two generations per year. The species is, however, discussed here only to clarify the type locality, since it was mostly erroneously interpreted in the past. F. Löw described the species from the material collected by Franz Then in the area 29 Acta entomologica slovenica, 14 (1), 2006 around Lesce and Bled (Lees-Valdes at that time) (Löw, 1881). Now this region belongs to Slovenia. Conci & Tamanini (1990), however, placed this type locality in Austria and Carinthia (Kärnten), what is wrong. Namely, even at that time this region belonged to the district Krain, which is now a part of the present Slovenia and not to Carinthia. Such misinterpretations are not rare for all of the species described at that time in the territory of the Austrian-Hungarian monarchy, which is not surprising due to the immense geopolitical changes, which followed afterwards. Acizzia jamatonica (Kuwayama, 1908): This eastern Palaearctic species has spread from Italy to Slovenia only very recently (Seljak, 2003; Seljak et al, 2004). In Europe it was recorded in North Italy for the first time (Alma et al., 2002). As early as in 2002 large populations were found on its host plant Albizia julbrissin in parks in Nova Gorica and soon elsewhere along the Slovene-Italian border as well. In 2003, it was found to be spread all over the south-western submediterranean part of Slovenia, and actually everywhere where its host plant is found planted (parks, parking places, gardens). Also in 2002, it was spreading also towards south in Istria (Umag, Poreo, Rovinj - Croatia). According to Oimala et al. (2006) it is continuing to spread along the coastal area in Dalmatia. The insect spreads mainly by being carried by traffic along the road network sand, partly also by active flying in searching for still unoccupied Albizia trees. Now it is considered as a very serious pest of Albizia julbrissin, threatening its ornamental value and functionality. Due to the weak lignification of shoots, heavy affected trees may often get frozen during the following winter. Phylloplecta trisignata (Löw, 1886): This species is widely distributed throughout the whole Mediterranean (Fauna Europaea, 2004). Its occurrence in Istria (Voloooa, Croatia) was already recorded by Gräffe (1911). A specimen captured on a yellow sticky trap in the Slovene coastal area (Parecag) in 2004 confirms its existence in this part of Europe. Diaphorina chobauti Puton, 1898 It is a very rare species in Europe. According to Burckhardt (1984) and Conci et al. (1993) it has only been known from Liguria in North-Italy so far. Otherwise, it is widely distributed throughout the Near East, in North Africa and in the central Asia (Burckhardt, 1984, Gegechkori & Loginova, 1990, Conci et al., 1993). In Slovenia, there are only three localities known in the southwestern submediterranean part of the country. Another locality has been discovered near the village Doberdob on the Italian side. However, all these localities are quite close together and belong to the same geographical region (fig. 5). Specimens were always swept from Convolvulus canthabrica L. plants, mostly at the end of May and in the early June. One specimen however was found the 01.10.2005. As Conci et al. (1993) in Italy give similar collecting periods, it is suggested that the species develops two generations per year. Bactericera perrisi Puton, 1876 There are some uncertainties about the occurrence of this species in Slovenia. Löw (1888) recorded it from Gorica (Görz) and Trnovski gozd (Tarnovaner Wald), which were also the only known localities in the territory of Monarchy at that time. Later Graeffe (1911) recorded it to occur also near Triest (Proseco). Under the 30 Gabrijel Seljak: An overview of the current knowledge of jumping plant-lice of Slovenia (Hemiptera: Psylloidea) presumption that Artemisia alba is the host plant of this species (Conci et al, 1997) (Artemisia campestris is very rare in Slovenia) it might occur rather common in this (south-western) part of Slovenia. Nevertheless, I could not find it in this region so far. On the other hand, the related B. kratochvili is rather common here. It has been collected very commonly by me on dry meadows with lots of Allium senescens. As B. kratochvili was described much later, confusion between these two species by Löw seems to be possible. Trioza senecionis (Scopoli, 1763) Slovenia is “terra typica” for this species. Scopoli (1763: 140) described it in his “Entomologia carniolica” for the first time, obviously from material collected in Carniola. An exact locality was not specified. As this species has not been found since then this record is still the only one existent for Slovenia. Its wider distribution, however, is to be expected, as its host plants (Senecio fuchsii, S. nemorensis) occur rather commonly in Slovenia. Trioza kiefferi Giard, 1902: So far, this species is only known from South Italy, Malta, Iberian Peninsula and Algeria (Conci, Rapisarda & Tamanini, 1996). In Slovenia Janeaio (1989) reported it to occur on Rhamnus fallax (=Rh. alpinus ssp. fallax) in several localities in the Slovene Alps. As his identifications were based merely on leaf galls by using Houard’s identification keys, he probably made the same mistake as many European plant gall researchers had already made before him. As Burckhardt (1983) stated, the resemblance of galls on Rhamnus alpinus compared to those on Rhamnus alaternus and Rh. lycioides produced by Trioza kiefferi in the Mediterranean area has led to misidentifications. Even more, according to the same author, galls on Rhamnus alpinus are not produced by any known psyllid. So far, in Slovenia I could only find adults of Cacopsylla rhamnicola (Scott, 1876) on Rhamnus fallax. Thus for all these reasons, I consider Trioza kiefferi as not existing in Slovenia. Discussion In the present review, the available data and records of jumping plant-lice occurring in the territory of Slovenia have been summarized. The fauna includes 100 species (Homotomidae - 1 species, Calophyidae - 1 species, Psyllidae - 65 species, Triozidae - 33 species). 44 of them (Psyllidae - 34 species, Triozidae - 10 species) are recorded for the first time in Slovenia. This number probably represents about 60-70 % of the whole diversity of this insect group in Slovenia. However, the knowledge of distribution range of the majority of them is still very fragmentary, because a more systematic faunistic work on this group has been started only recently. An exception may represent the galls producing species, which were reported by Janeaio fairly comprehensive (Janeaio, 1989). Despite that, the number of above listed species already exceeds the diversity recorded in the adjacent Italian region Friuli-Venezia Giulia - 84 species (Conci et al. 1992 and 1997) or in Carinthia (Austria) respectively - 82 species (Burckhardt et al. 1999). The proper identity of Bactericera curvatinervis, B. perrisi and Trioza dispar in earlier records 31 Acta entomologica slovenica, 14 (1), 2006 is somewhat ambiguous and are in need of verification. In the text they are marked by a question sign in square brackets.
