Acknowledgments:
This study is part of research cooperation initiatives between the University of Tyumen, Russia, and the Universidade Federal do Norte do Tocantins (agreement No. 3П/845-24 of 24.10.2024). The gratitude is due to Prof. Freud Romão (INOVA-In Center, UFNT, Araguaína, Brazil) for providing overall support to collaboration. We are thankful to Dr. Artyom V. Stepanov (X-BIO Institute, University of Tyumen, Tyumen, Russia) for providing fungi from cultured media. The study was supported by the Ministry of Science and Higher Education of the Russian Federation within the framework of the Carbon Measurement Test Area in Tyumenskaya Oblast (FEWZ-2024-0016).Abstract:
Laboratory culturing of Galumna flabellifera Hammer, 1958, Pergalumna brasiliensis (Sellnick, 1923) and P. decoratissima Pérez-Íñigo and Baggio, 1986 (Oribatida: Galumnidae) was conducted. The development period from larva to adult at ≈25 °C was 23–27 days (mean ≈25) for G. flabellifera, 27–45 (≈35) days for P. brasiliensis and 35–43 (≈38) days for P. decoratissima. For the latter species, the total development from egg to adult took 49–54 days (mean 50). All active instars fed on Alternaria sp. and Pleurococcus sp.; however, adults preferred fungi, while juveniles preferred algae.
