1576. An overview of alien Diptera in SloveniaMaarten De Groot, 2013, original scientific article Abstract: The nonindigenous Diptera occurring in Slovenia are overviewed based on literature data. In total, 18 species belonging to eight Diptera families are alien to Slovenia. Most of the species originate from North America and continental Asia. The first record of an alien Diptera species (Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae)) was made in 1959, but the bulk of the species were recorded for the first time in the last two decennia. Most of the species were found in the pre-Alpine and sub-Mediterranean regions. The distribution and abundance of the alien Diptera are not fully known, as in most cases only the first observations were published. Most of the species are phytophagous and are known pests in agriculture and forestry. A list of expected nonindigenous Diptera species for Slovenia is given. It is suggested that a monitoring system should be developed in order to understand the population dynamics and the impact of the alien species on the ecosystem and economy.

1577. Additions and omissions to the list of hoverfly fauna (Diptera: Syrphidae) of SloveniaMaarten De Groot, Roman Luštrik, Tim Faasen, Dare Fekonja, 2010, original scientific article Abstract: The changes in the checklist of hoverflies of Slovenia are presented. Fifteen species are recorded as new for the fauna of Slovenia: Brachyopa panzeri, Brachypalpus laphriformis, Callicera aenea, Chamaesyrphus scaevoides, Chalcosyrphus valgus, Melangyna lasiophthalma, Meligramma guttata, Merodon aberrans, Parhelophilus frutetorum, Orthonevra intermedia, Platycheirus occultus, Rhingia borealis, Spazigaster ambulans, Sphaerophoria chongjini and Sphaerophoria fatarum. From the species complex of Merodon aeneus, both M. aeneus species A/B and M. aeneus C were recorded. One species, Xylota caeruliventris, was omitted from the checklist because of misidentification. Information on habitat characteristics, range and conservation status is givenfor every new species.

1580. Influence of microwave heating in wood preservation on traditional surface coatingsMartin Klinc, Matjaž Pavlič, Marko Petrič, Franc Pohleven, 2017, original scientific article Abstract: Microwaves are very effective at wood pest eradication. However, elevated temperatures may pose a risk of damaging surface coatings used on cultural and historical artefacts. Therefore, we monitored changes in patterns of the original paint taken from such objects along with newly prepared coatings. We evaluated visual, mechanical, and chemical modifications of coatings when exposed to microwaves (750W, 2.4GHz), at 60°C or 80°C for 10 min. Whether old or new, only water-based coatings have proven to be resistant to elevated temperatures and no damage was observed at 80°C. Blisters have formed on layers of new oil paints and natural resins due to insufficiently cured film. Temperatures above 80°C may cause melting of coniferous wood resin and thus transport of resin to the surface; on the other hand, temperatures up to 60°C are completely harmless. Mechanical and chemical changes of coatings exposed to microwaves were not observed, but the studies showed that colour and gloss exhibited minor changes.
