Abstract: The enchytraeid fauna of the Rax mountain range (Austria) was investigated. Samples were taken from five different habitats: under Pinus mugo, under Picea abies, under Larix decidua, from a mixed forest (P. abies with Betula pendula) and from an alpine meadow. Forty one enchytraeid species belonging to 12 genera were found and additionally the terrestrial polychaete Hrabeiella periglandulata. In addition to the very frequent species, Fridericia discifera Healy, 1975, another species with very similar spermathecae but differing in some traits was also observed. The characters which could be used to discriminate this new species, F. alpica sp. n. from F. discifera are discussed in this paper. Another species collected from the study site, F. raxiensis sp. n. was also new to science and is described based on both morphological and molecular taxonomic methods.
Key words: enchytraeid fauna, new Fridericia species, molecular analysis, Rax Mountain.

Acta Zoologica Academiae Scientiarum Hungaricae 64 (1), pp. 75–90, 2018 Title: Efficiency against the Two-spotted spider mite Tetranychus urticae and prey-age-related choice of three predatory mites
Authors: Enikő Gyuris1,2, Erna Szép1,2, Jenő Kontschán2, Attila Hettyey1 and Zoltán Tóth1 Authors' addresses: 1Lendület Evolutionary Ecology Research Group, Plant Protection Institute, Centre for Agricultural Research, Hungarian Academy of Sciences, H-1022 Budapest, Herman Ottó út 15, Hungary, E-mails: gyuris.eniko@agrar.mta.hu, szep.erna1@gmail.com, kontschan.jeno@agrar.mta.hu, hettyey.attila@agrar.mta.hu, toth.zoltan@agrar.mta.hu Abstract: Specialist and generalist predator mites have been recommended against the Two-spotted spider mite (Tetranycus urticae) as biological control agents, but their effectiveness in population regulation has been rarely examined under circumstances when prey had the opportunity to express antipredatory responses. We tested the efficiency and preference for prey life stages of three predator mites, one specialist (Phytoseiulus persimilis) and two generalists (Amblyseius swirskii and Iphiseius degenerans). We used two predator densities and performed the experiment under ‘seminatural’ conditions. We found that significantly less eggs and adult spider mites survived in the presence of P. persimilis compared to the control group, and this predator mite consumed more eggs at high density than the other predators. In the presence of A. swirskii fewer adult spider mites survived at low density compared to the control, whereas egg survival was lower than in the control group at both densities. In the presence of I. degenerans, only the survival of eggs was lower than in the control group and only at high density. Our results suggest that the generalist A. swirskii, but not I. degenerans, may be efficient in regulating prey populations through egg consumption, and, thus, represents an alternative to the effective specialist predator.

Authors: Zoltán Soltész1,2, Nándor Seres3 and Anikó Kovács-Hostyánszki1 Authors' addresses: 1Lendület Ecosystem Services Research Group, Centre for Ecological Research, Hungarian Academy of Sciences, H-2163 Vácrátót, Alkotmány u. 2–4, Hungary, E-mails: soltesz@entomologia.hu, kovacs.aniko@okologia.mta.hu Abstract: The Red-footed Falcon (Falco vespertinus) is a strictly protected raptor species in Hungary (ca 600 pairs). It naturally breeds in rook, crow or magpie nests that are rebuilt every year, however, most of these nests disappeared by the end of the 20th century. In the early 2000’s more than a 3,000 artificial nest boxes were installed in the country, increasing the number of breeding pairs considerably. This prompts the question whether breeding birds might face an increased number of nest-dwelling ectoparasites due to the annual re-use of nesting sites. The nest material was collected from 59 nest boxes (not cleaned for 3 years) in Northern Hungary after the breeding season in 2009 and from 17 nest boxes (cleaned in previous year) in 2010. Emerging dipteran imagoes were identified to species level. Altogether 45,487 individuals of 42 fly species (2010: 37, 2011: 14) were reared; 88.1% of that was Carnus hemapterus, a well-known blood-sucking parasite. The number of C. hemapterus was significantly higher in nests where the last breeding bird species was Common Kestrel than Red-footed Falcon. In freshly cleaned nest boxes one order of magnitude lower number of C. hemapterus specimens were found. Our results indicate the necessity of cleaning the nest boxes annually. Key words: bird nest, Carnus hemapterus, nest box cleaning, parasites, saprophytic flies. DOI: 10.17109/AZH.64.1.91.2018

Authors: Alexander Csanády and Anna Onderková Authors' address: Institute of Biology and Ecology, Faculty of Science, P. J. Šafárik University, Šrobárova 2, SK-054 41 Košice, Slovakia, E-mail: alexander.canady@gmail.com Abstract: In this study we investigated allometry and variation in the baculum of the stoat Mustela erminea and compared it with head-and-body length not involved in reproduction. The stoat is a species with pre-copulatory selection (manifested by the high degree of male-biased sexual size dimorphism) therefore we predicted that baculum allometry may be isometric or exhibited negative allometry. We also test the hypothesis that the baculum size is positively correlated with adult body size and may be used as a reliable indicator of male good condition. Results presented in this study were different according to which regression model type was used. While the OLS slope for baculum length in M. erminea indicated negative allometry, the RMA model showed positive allometry. The results obtained for M. erminea weren’t in agreement with mentioned hypothesis that if baculum allometry is affected by the degree of pre-copulatory selection relative to post-copulatory selection, then we predict isometry or negative allometry of the baculum. Nevertheless, we suggest, that to confirm the above statements further analysis of more numerous material of M. erminea coupled with comparative analysis of testicular growth studies are needed to fully understand the importance and function of the baculum relative to the mating system.
