Abstract: The Small Emperor Moth ― Saturnia pavonia L., is a moth of the family Saturniidae. This moth occurs throughout the Palearctic region ― both eastern and western. Based on data on the distribution of the species in the South of Russia and the North Caucasus, we assumed the presence of Saturnia pavonia L. habitats on the territory of the RNO-A. The moth is classified as rare and endangered and listed in the Red Books of various ranks, obtaining new information about its distribution is an urgent task. The aim of the work was an inventory of the moth’s fauna of the republic. Standard generally accepted methods of visual observations, biomaterial collection, photo fixation and office processing of entomological materials were applied. The research was carried out from 1985 to 2023, throughout the territory of RNO-A ― from the steppe to the alpine belt, at absolute altitudes of 130-3500 m above the s. l. Many years of research have not yielded records of this species of moth. Finally, in the spring of 2023, the Small Emperor Moth was found in the west of the republic on the border with the Kabardino-Balkar Republic in wild-fruited plantings. This is the first and only discovery of this moth’s species in North Ossetia.

Abstract: The utilization of separate culture chambers serves a dual purpose: it not only facilitates the creation of a hypoxic environment but also contributes to the establishment of a consistently stable local environment. This, in turn, mitigates environmental stress factors. The primary objective of this experiment was to assess the developmental potential of sheep embryos before their implantation. This assessment was conducted within the confines of 304 stainless steel culture chambers, offering a viable alternative for maintaining a stable in vitro embryo culture environment. The experiment involved a comparative analysis between the development outcomes of parthenogenetic and reconstituted sheep embryos cultured in both stainless steel tanks or MIC-101 incubators over a period of 7 days. Notably, the blastocyst rates for parthenogenetic embryos were 26.45% and 24.84% in stainless steel tanks and MIC-101 incubators, respectively, with no statistically significant difference (P>0.05) between them. Similarly, the blastocyst rates for reconstituted embryos stood at 16.07% and 16.84% (P>0.05) for stainless steel tanks and MIC-101 incubators, respectively. It is worth highlighting that the incubation system, comprising a 304 stainless steel tank, a standard gas mixture, and a thermostat, presents an in vitro culture system with the advantages of cost-effectiveness, environmental stability, and efficacy.
