After a brief topographic and topoclimatic presentation of the cave, the paper provides a taxonomic approach to the troglophil and troglobiontic micromycetes and algae occurring in the cave. The investigation revealed the presence of 6 strains of micromycetes, a bacterial strain, 5 blue-green algae ( Cyanoprokaryota ), 4 taxa of xanthophytes ( Xanthophyta ) and 12 green algae ( Chlorophyta ) in the soil, on calcareous cave walls, in condensed water and limestone pool water. Located at an altitude of 304 m a.s.l., on the left side of the Cri şul Repede River, between the localities Şuncuiu ş and Vadu Cri şului, the Vadu Cri şului cave is the main element of the “Defileul Cri şului Repede” (Cri şul Repede Strait) Nature Reserve and one of the most important habitats of the underground fauna in the Apuseni Mountains. The cave gallery has formed along a diaclase and it is penetrated by an underground water flow, except for an upper cavity, i.e . the balcony hall, which is the only part exhibiting outstanding concretions (Fig. 1). The first siphon occurs at 655 m from the entrance and may be penetrated only during dry periods, while the second siphon located at the end of the cave is always closed. Although the cave is 1000 m long, it is not subjected to external meteorological influences except for the first 100 m. R a c o v i ţ ă [10] described the cave as a cavity exhibiting permanent bidirectional ventilation. This topoclimatic type is in perfect agreement with the general topography of the cave, which is a practically horizontal one-entrance cavity. This sole opening concentrating all the aerodynamic exchanges with the outer world is the site of two air currents of opposite directions. The lower part of the gallery is affected by an ascending current during winter and a descending one during summer. The limits in time of the two ventilation types correspond to October and May, so that winter lasts for seven months and summer for five. * Babe ş-Bolyai University, Department of Experimental Biology, 400006 Cluj, Romania. E-mail: [email protected] ** Babe ş-Bolyai University, Department of Taxonomy and Ecology, 400006 Cluj, Romania *** Deceased L. RÁKOSY-TICAN, L. MOMEU, F. LŐRINCZI The annual ventilation-dependent variations in air temperature have two different characteristics: at floor level the thermic values are directly influenced by outer temperatures only during winter, while in summertime the mean thermic value remains constantly around 10.2 o C. Annual relative humidity ranges between 98 and 100% [10]. F i g. 1. The map of the Vadu Cri şului cave . The sampling sites are indicated by ▲. Ventilation speed varies according to season; yet the speed of ascending winter current resembles that of the descending summer one. Evapocondensation is strictly dependent upon ventilation: condensation typically occurs during summer, while the winter current change brings about an increasing evaporation intensity with ventilation speed. Light intensity in the lower half of the gallery drops sharply along the first 20 m from 3200 lux (outside) to 0.1 lux (October 31, 1980). Few data have been reported as regarding microbiota of the Vadu Cri şului cave [5]; consequently, the aim of our study was to investigate from a taxonomic point of view the troglophil and troglobiontic micromycetes and algae occurring in the cave. Materials and methods. The first studies were carried out in the cave (October 31, 1980) and comprised temperature, water pH and light intensity meas- urements (by means of field thermometer, pH-paper and luxmeter) and underground microscopic investigation (portable light microscope). As the resulting data were not conclusive, due to poor magnifying possibilities and scarce occurrence of organisms, samples were collected for further laboratory investigation (December 8, 1980) either in sterile test tubes or in tubes with culture media. The microclimatic measurements were repeated. Micromycetes were isolated from samples obtained from cave sediments, limestone pool water and calcareous walls (pelicles, crusts or spots displaying different colours and consistency against the bearing rocks) and preserved in sterile test tubes. Sterility of tubes was achieved by maintenance in drying oven at 105 o C for 48 h. Czapek medium solidified with agar was used for inoculation. Incubation took place in laboratory lockers in the absence of light at room temperature (19-22 o C). The cultures were macro- and microscopically examined after 14 and 28 days of incubation. 4 MICROBIOTA IN THE VADU CRI ŞULUI CAVE Algae were collected from limestone pool water samples and the underground water flow, and subsequently transferred in sterile test tubes. These samples were imediately fixed in 4% formol. Other samples collected from limestone pools, soil and calcareous walls were inoculated on mineral culture media, such as Knop- Pringsheim (KP), Benecke (BK) or Watanabe (W) [9]. Incubation was carried out in light at room temperature (19-22 o C) for about 3 months, until colonies were clearly visible. The taxonomic identification of algae was carried out by light microscopy.

E-mail: [email protected] Abstract: Nano-particles have become one of the most promising new approaches for pest control in recent years. In this study, laboratory trails were carried out to investigate the insecticidal potential of TiO2 nano-particles against nymphs and adults of Eurygaster testudinaria. TiO2 nano-particles were found to be highly effective against E. testudinaria. The results also showed that mortality rates of adults and nymphs were significantly increased with days after application and concentration of TiO2 nano-particles with 41.15% and 43.08% mortality, respectively at 100 mg/L after 7 days from treatment. Results indicated that TiO2 nano-particles can be used as a valuable way in pest management of E. integriceps to reduce the indiscriminate use of conventional pesticides.

  • Insecta: Hemiptera: Heteroptera)
    © Zool.-Bot. Ges. Österreich, Austria; download unter www.zobodat.at Acta ZooBot Austria 155, 2018, 251–256 Snapshot of the terrestrial true bug fauna of the Pocem floodplains (Insecta: Hemiptera: Heteroptera) Wolfgang Rabitsch 61 terrestrial true bug (Heteroptera) species are reported from a short field trip in April 2017 along the river Vjosa in the Pocem floodplains, Albania. Five species are reported for the first time for Albania, indicating insufficient baseline information on the distribution of true bugs in the region. Future sampling designs should consider the interstitial habitats, river gravel and sand banks, and adjacent dry grassland areas. Certain difficulties aside, true bugs are a significant group of insect species with de- scriptive and indicative value. RABITSCH W., 2018: Momentaufnahme der terrestrischen Wanzenfauna im Pocem Überschwemmungsgebiet (Insecta: Hemiptera: Heteroptera). Während einer kurzen Exkursion im April 2017 entlang des Flusses Vjosa im Pocem Überschwemmungsgebiet, Albanien, wurden 61 terrestrische Wanzenarten (Heterop- tera) festgestellt. Fünf Arten werden der erste Mal für Albanien gemeldet, ein Hinweis auf die unzureichende Datenlage der Verbreitung von Wanzen im Gebiet. Zukünftige Erhebungen sollten insbesondere die interstitiellen Habitate am Flussufer, Sandbänke und die angrenzenden Trockenrasenstandorte untersuchen. Trotz gewisser Schwierig- keiten sind Wanzen als Deskriptoren und Indikatoren der Lebensräume eine aussage- kräftige Insektengruppe von hohem Wert. Keywords: Albania, floodplain, Heteroptera, new records, riparian, river. Introduction True bugs (Insecta: Hemiptera: Heteroptera) are well-known descriptors and indicators of terrestrial and aquatic habitats and their ecological quality (Duelli & Obrist 1998, Achtziger et al. 2007, Rabitsch 2008, Skern et al. 2010). Due to their diversity of feeding habits, life-histories, biology, and preferred habitats, true bugs are a meaningful addition to any Environmental Impact Assessment (e.g.

In the case of insects, most published DNA barcoding studies focus on species of the Ephemeroptera, Trichoptera, Hymenoptera and especially Lepidoptera. In this study we test the efficiency of DNA barcoding for true bugs (Hemiptera: Heteroptera), an ecological and economical highly important as well as morphologically diverse insect taxon. As part of our study we analyzed DNA barcodes for 1742 specimens of 457 species, comprising 39 families of the Heteroptera. We found low nucleotide distances with a minimum pairwise K2P distance ,2.2% within 21 species pairs (39 species). For ten of these species pairs (18 species), minimum pairwise distances were zero. In contrast to this, deep intraspecific sequence divergences with maximum pairwise distances .2.2% were detected for 16 traditionally recognized and valid species. With a successful identification rate of 91.5% (418 species) our study emphasizes the use of DNA barcodes for the identification of true bugs and represents an important step in building-up a comprehensive barcode library for true bugs in Germany and Central Europe as well.

Halyomorpha halys has not established itself in Australia, but it has been intercepted several times at the border, therefore future incursions and establishment are likely. There are few control options for this species and biological control may be a useful management method in Australia. This study summarizes the literature on natural enemies of H. halys in its native and invaded ranges and prioritizes potential biological control agents that could be suitable for use in Australia. The results show two egg parasitoid species as the Citation: Caron, V.; Yonow, T.; Paull, best candidates: Trissolcus japonicus (Ashmead) and Trissolcus mitsukurii (Ashmead) (Hymenoptera: C.; Talamas, E.J.; Avila, G.A.; Hoelmer, Scelionidae).
