Description
As for beneficial fauna, the most number of parasitic hymenoptera is noticed in organic orchards. The least quantity of parasitic hymenoptera can be met in conventional orchards. The characteristic feature of arthropods in conventional orchards in 2008 was the frequent occurrence and rather big number of acariphages (ladybirds of Stethorus family). The occurrence of the considerable quantity of predatory bug Campilomma and the bugs of Orius family was registered. All the enumerated species attack phytophagous mites. With the assumption of phytophagous mites population increase in organic orchards, the increase in Stetorus specimen was registered. Acariphages in ecological orchards occurred rarely. So we can suggest that predacious insect species – Stetorus, Campilomma, Orius –can serve as a certain indicator showing one or another population density of phytophagous mites in apple-tree orchards.

Description
The review considers a present level of knowledge of terrestrial gastropod olfactory system. Special attention is given to data concerning presence of electrical coupling on different levels of terrestrial gastropods olfactory analyzer functioning. Analysis of available literature leads to conclusion that further study of neural gap junctions in terrestrial gastropods olfactory system will provide a significant development in its structure and function modeling

Description
Along with traditional ways, the biotechnological methods become more significant in contribution to plant conservation in situ. The work is dedicated to elaboration and advancement of the method of isolated tissues and organs culture for conservation and reproduction of the badan, Bergenia crassifolia L., the rare species of Saxifrgaceae family. The conducted study yielded the regenerated plants of B. crassifolia from seeds. For the first time, we have performed conservation and reproduction of B. crassifolia in vitro under conditions of Yakutia

Description
One of the ways to save rare species of plants is to create models of natural communities on the grounds of the botanical gardens. In the Botanical Garden of Kuban State University we have created the model of forest communities with the participation of rare and endangered species, and we are still working on creating models of herbaceous communities. We have introduced 18 species of plants of the flora of the Krasnodar region in the forest community and more than 30 species in herbaceous community

NETSUKE AS A RESOURCE OF INFORMATION ABOUT SPECIES DIVERSITY OF LAGENARIA SICERARIA (MOLINA) STANDL
DescriptionIn the article, with a descriptive method and a method of analysis and synthesis, we have conducted a study of species diversity of Lagenaria on the basis of a miniature sculpture of netsuke. In Japan and China, in the period from the 17th to the 20th century, the most common was 9 species. The biological peculiarities of some rare species of lagenaria has been described
