Since the 21st century, developed countries have paid increasing attention to bioeconomy strategies. In particular, since the spread of the New Crown Pneumonia epidemic, global biotechnology has surged, and the impact of significant public health and safety events has continued to escalate. Bioeconomy strategies have received unprecedented attention. In this context, sorting out and studying international bioeconomy strategies is essential. Therefore, this paper reviews selected national bioeconomy strategies and explored their characteristics.

Hunting for waterfowl is the most massive for amateur hunters in Russia. Hunting starts in spring and autumn, and the largest number of hunters take part in it, due to its popularity, low economic cost for hunters, as well as the possibility of using a hunting dog. In this regard, the role of counting waterfowl in autumn is important. The organization and conduct of accounting work should be carried out by hunting organizations annually, within certain calendar terms, and at a high-quality level.

The scleractinian coral is common along the Red Sea coast, and its reproductive mode and period of reproduction were assessed using histological preparations. the sexuality, and reproductive mod timing of reproductive of pocillopora damicornis from adjacent to the fringing reefs of the Ubhur Creek in the Red Sea, were assessed using a serial histological section. Sexual reproduction in pocillopora damicornis a shallow water hermatypic coral was studied from December 2011 to November 2012. pocillopora damicornis is a simultaneous hermaphrodite with ovary and testis in the project into the body cavity on the same mesentery. Sperm and eggs were usually released simultaneously from the same polyp. The onset of the reproductive period of pocillopora damicornis was found to be limited (April to May). In the number of eggs and testes observed in this period, the gonads were found in the polyps. The pocillopora damicornis egg size ranged from 49.80 µm (in March) to 125.0 µm (in May). Four stages were chosen, to reflect very immature ovaries, the early stages of oocyte development, ova near maturity, and mature ova, and also four distinct stages of sperm development were identified. The state of gonads development (eg. testis and eggs) was measured by a calibrated eyepiece micrometer of a compound light microscope. Zooxanthellae were presented in the mature oocytes in pocillopora damicornis. This study aimed to examine the reproduction mode and timing of pocillopora damicornis.

Apitherapy is the use of bee products such as honey, pollen, propolis, royal jelly, bee venom, and wax is used to prevent or treat illness and promote healing. The objectives of this study are to assess and document indigenous knowledge on the medicinal values of bee products in Ethiopia and generate baseline information on indigenous practices of the medicinal value of beehive products for further study. This study was conducted in beekeeping potential areas of Oromia Regional state by selecting seven zones and from each zone two districts and a total of 14 districts (Woreda) based on their potential for beekeeping, the existence of long-aged bee-keepers and accessibility. using a purposive sampling method and questionnaires were distributed to the elders and well-known traditional healers of the study areas. In answering the questionnaires 22-100 ages dwellers or respondents participated. The survey was conducted in 7 zones namely Jimma, Ilu ababora, West wollega, East wollega, East Shoa, West shoa, and Buno Bedele. Simple descriptive statistics were used to analyze the data obtained by collected questionnaires. The result of the study showed that 49.3% of Apis mellifera honey and 31.9% of stingless bee honey, majorly used bee products for apitherapy, and 70.3 % of the bee products used using traditional collection method. According to this study’s results, the traditional drug was prepared from honey in liquid form which comprises the biggest portion mark of 63.4% of respondents. The majority of the respondents strongly agree with bee products as a treatment for different diseases such as asthma, cough, common cold, TB, and wounds. A major challenge faced during using of bee products as medicine is the absence of awareness of apitherapy as it was reported by 28.8%. of the respondents. Thus, it can be concluded that bee products are well-known apitherapy in the Oromia region and it was recommended that awareness creation of bee products as apitherapy and further research on the medicinal value of beehive products for confirmation as medicine for different diseases since it may be a solution for various diseases resisting modern drugs.

The experiment was conducted to evaluate different Brachiaria brizantha accessions at the Wondo genet agricultural research center to identify species/accessions so as to use the better performing ecotype for wider distribution among livestock producer communities in the country. Seven Brachiaria grass accessions (B. brizantha, 13151; B. brizantha, 13368; B. brizantha, 13653; B. brizantha, 16550; B. humidicola, 9222; B. brizantha, 13379 and B. mutica,) were used as treatments in randomized complete block design with three replications. The overall dry matter yield for B. humidicola, 9222 (5.95t/ha), and B. mutica, (5.61t/ha) accessions didn’t show a significant difference (p > 0.05) but significantly (p < 0.05) lower than all other accessions. Mean plant heights for the accessions were significantly different (p < 0.05) throughout the harvesting cycle period and overall yield with a lower plant height of B. mutica (63.2 cm) while non-significant (p > 0.05) overall mean height was recorded among other accessions. B. brizantha, 13151; B. brizantha, 13368; B. brizantha, 13653; B. brizantha, 16550 and B. brizantha, 13379 accessions outperformed in terms of overall dry matter yield. Further studies on agronomic performances of promising B. brizantha accessions under on-farm conditions and nutritional evaluation involving live-animal experiments are recommended.

The article is dedicated to the memory of Semyon M. Hertz, a talented radiophysicist engineer and remarkable person who left us prematurely at the age of 74. He devoted most of his scientific activities to biology, primarily phototrophic organisms, using radionuclide substances. The main achievements in the study of photosynthesis made thanks to his physical and mathematical calculations and engineering developments, are described. The ability to overcome difficulties, fortitude, vitality, and optimism of Semyon Hertz were noted.

Parasitoids are important regulators of insect populations and stand out as the main group of natural enemies in agricultural systems.
