The respective sex attractants performed significantly better in the Orthosia spp. than the SBL lure, which, although regularly catching low numbers of both females and males, did not differ significantly from zero catch in unbaited control traps. On the other hand, the SBL lure performed as well as the sex attractant in C. vaccini. Sizeable catches of C. rubiginea, C. rubiginosa and C. erythrocephala were also recorded in traps with the SBL lure. The SBL lure can prove to be a useful tool in ecological and faunistical studies of Conistra and related hibernating Xylenini species.

Monitoring and detection of these pest species is routinely performed by traps baited with sex-pheromones. Baits that attract both males and females were developed for improved pest management. First the effectiveness of different synthetic compounds was evaluated. We also tested semi-synthetic baits that contained both synthetic and natural components (wine and beer). These were more attractive for moths considering species richness and abundance. Disadvantage of this increased effectiveness is that the traps catch more non target, rare and even protected species. In this study we analysed the effect of semi-synthetic baits developed for Noctuid moths containing wine on other non-target Lepidopterans. In the six sampling sites traps caught 17158 individuals of 183 Lepidoptera species. The number of Noctuidae species was 124, while their proportion was 84.4%. The traps caught 813 individuals of 9 protected and 20 valuable species, which was only 4.7% of all Lepidopterans. In contrast the mean proportion of 33 dangerous and potential pest species was 31.3% (5375 individuals). Number and abundance of both protected and pest species were affected by landscape structure. The risks of catching non-target species was higher in species rich natural and seminatural landscape. In homogenous arable lands the number and proportion of valuable Lepidopterans was not significant.

Isoamyl alcohol-based baits generally attracted more flies than phenylacetaldehyde-based baits and unbaited controls; however, the phenylacetaldehyde-based traps were the most attractive to the Empididae and Milichiidae families. The isoamyl alcohol-based semisynthetic lure showed significant attractivity to the families of Muscidae, Ulidiidae, Sarcophagidae, Calliphoridae, Sciomyzidae, Heleomyzidae, Drosophilidae, Phoridae and Platystomatidae. Additionally, isoamyl alcohol-based semisynthetic lure is the first reported attractant of the Sciomyzidae family. Since our phenylacetaldehyde-based floral lure was also attractive to Heleomyzidae flies, both types of lures can be seen as the first known attractants of this f...

As a result of climate change, warming winters and changes in landscape structure, the distribution and frequency of Bombus species is constantly changing. To develop appropriate protection strategies, it is essential to monitor them and update the occurrence and threat status of the species. The last review of the distribution of Bombus species in Hungary was completed 20 years ago. Here we present updated distribution maps based on published data from the last 20 years together with unpublished data collected in 2018–2021. Based on the new data, we examine changes in the last two decades. In the case of 9 species further studies should be carried out to confirm the presence of stable populations, while 3 species are recommended for protection by law in Hungary. Seven species showed increasing frequency, B. arg...

This diversity is in decline due to land use intensification and abandonment. Natural and semi-natural grasslands of the Carpathian lowlands have become endangered over the 19th century. However, some remains of former wetlands have survived land use change in the Bereg Region (North-eastern Hungary and Eastern Ukraine). We surveyed Orthopterans as sensitive indicators of habitat structure and microclimate in grasslands. We identified three different Orthoptera assemblages and their character species. Although rare and especially valuable species were not found in the studied sites, the species rich remains of wetlands still protected relics of former wildlife of wetlands. Understanding the quantitative character of the assemblages, ratios of life forms and particularly co-occurrences of their character species (Chorthippus dorsatus, Leptophyes albovittata, Tettigonia viridi...

In Hungary, it was detected in 2012 for the first time, but its distribution in the eastern part of the country had been not studied. During the present investigation nine sampling sites in the northeastern part of the Carpathian lowlands belonging to Hungary, Ukraine and Romania were studied with baited traps. D. suzukii was detected in all seven Hungarian sites and in the one Western Ukrainian site where sampling occurred. Amongst the Hungarian sites, six had not previously been studied and the data provided here are the first for Western Ukraine and the second for this country following the published record from Yalta (Crimea, southeast Ukraine).

Here, we present the results of a six-year survey (2015-2020) carried out in four sampling sites of the Ukrainian part of the Bereg Plain and provide the actualised checklist of this area. Actually, 7346 specimens of 53 caddisfly species were collected. The number of known caddisfly species increased from 13 to 61. Two species Hydropsyche guttata and Parasetodes respersellus, which formerly were considered extinct in the Pannonian Ecoregion, were detected and another especially rare species (e.g. Cyrnus flavidus) was also recorded. The fauna of the region cover a significant part of both Hungarian and Ukrainian caddisfly fauna. Assemblages of four characteristic habitat types of the region showed significant differences considering their quantitative and qualitative composition, substrate, current, hydrological- and feeding types. The high diversity and natural value of the small lo...

In the Carpathian basin, the West Ukrainian Transcarpathia county was the last region where this speci es has not been found yet. The first specimens of this invasive pest were sampled in Velyka Dobron' in 2018 and in 2019 it was found in anothe r neighbouring village and cities of Chop, Berehove and Uzhhorod. The data provided here is the first for West Ukraine and the second for the country following the published record from Odessa (SE Ukraine). Although H. halys is still less abundant and occupied mainly urban habitats, it will certainly cause nuisance for peoples and damages for farmers in the near future.

Ezért a klímaváltozás témaköre eleve az interdiszciplináris megközelítést igényli. Szükségessé teszi, hogy a különböző szakterületek képviselői kicseréljék tapasztalataikat, összegezzék tudásukat, és dialógus alakuljon ki a különböző társadalmi szférák és a döntéshozók között is, egy, a mainál környezettudatosabb, és a klímaváltozás kihívásaival szemben hatékonyabban reagáló társadalom létrejötte érdekében. Az interdiszciplináris megközeítés hozhat közelebb a ma még megválaszolatlan kérdések megoldásához is, ahogy ezt az alábbiakban szeretném megmutatni, egyben keretet adva a következő tanulmányokhoz is.
