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
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.

The article presents the researches of rats testicular morphology in oxidative stress induced by adapta-tion to low temperatures and its correction with Dihy-droquercetin. It was revealed that in oxidative stress Dihydroquercetin has protective properties prevent-ing spermatogenesis disorders and Leydig cells death in rat testis

DETERMINATION OF ACUTE TOXICITY OF BIO HUMATES
DescriptionIn the work, we present the results of the investigation of acute toxicity of bio humates obtained by the method vermicultivation on laboratory animals. In the diets of farm animals and Pets to fill in the missing nutrients in the past years, we had an extensive use of various feed additives. Among them, mineral (macro - and micronutrients), protein and fat supplements, vitamins, biostimulants, complex natural compounds (sapropel, peat), synthetic products (enzymes, hormones, antibiotics, adaptogens, antioxidants). The search for new ways of improvement and increase of efficiency of agricultural animals using feed additives with high demands on ecology of meat and dairy foods naturally led to increased studies on the use in livestock farming of water-soluble alkaline salts of natural humic acids - humates. Their environmental safety and the unique ability to improve metabolism and increase energy cells very positively manifested in living organisms. Numerous studies Russian and foreign scientists installed a high efficiency natural humates as biostimulators and immunomodulators in animal husbandry and veterinary medicine. Accumulated extensive experimental material, proving that the use of humates leads to faster growth of animals, reducing morbidity and mortality, increase the body's resistance to toxins in feed and resistance to adverse environmental conditions. Improving with the help of humates ecological purity of the ecosystems "water — soil — plant", as well as the health of birds, animals and fish will ultimately lead to strengthen health and to prolong human life as a consumer of agricultural products. Currently, the livestock market is intensively increasing the humates produced in Russia and abroad from brown coal, peat, sapropel. A special place among them has been occupied by the newest formulations because of a unique combination of safety, efficiency, and value, which, thanks to its amazing properties to increase energy cells, stimulate vital processes and to enhance the beneficial effects of other substances called energine. They are harmless to animals and humans; do not have allergologie, anaphylactogenic, teratogenic, embryotoxic and carcinogenic properties when used in recommended doses. This allows you to create on their basis organic natural feed additives and veterinary medicines for agricultural animals, birds, fish, fur animals and Pets, and preventive and therapeutic drugs for humans

DETECTION OF SEROTYPE SPECIFICITY OF AFRICAN SWINE FEVER VIRUS NON-HAEMADSORBING STRAINS
DescriptionGamma irradiation-inactivated cultural preparations (-IP) of African swine fever (ASF) non-haemadsorbing strains acquire a potential for haemadsorption induction in porcine bone marrow culture (PBMC). We have obtained some experimental data indicating that a modification of haemadsorption inhibition assay (HIA) which is an assay aimed at “removal” of γ -IP-induced haemadsorption may be used in research works to determine serospecificity rates of ASF virus non-haemadsorbing isolates

DETERMINATION OF HEAVY METALS IN THE PHYTOMASS AND THE METHOD OF ITS DISPOSAL
DescriptionThe need for constant monitoring of the environmental situation due to the fact that at the present time almost all the ecosystems of our planet suffer in one way or another degradation under the influence of the anthropogenic factor. In the present work we summarize the results of 6 years of monitoring to determine heavy metals in the air. Industries and domestic waste and, in particular, road transport is the main source of pollution. The share of vehicles to air pollution in cities reaches 70-90%. The greatest danger to public health is compounds of lead, cadmium and mercury relate to 1 class of danger. We have studied the dynamics of accumulation of heavy metals and carbon monoxide in the atmosphere of Krasnodar on the streets with different intensity of car traffic. The data obtained indicate a significant excess compared to the control of the content of such metals as lead, iron, cadmium, and copper in all samples; chromium and zinc at three positions of the four. We pay due attention to the increase in the concentration of cadmium compared with data from previous years. It is established that the dynamics of accumulation of heavy metals in the atmosphere of the city is well correlated with population, the intensity of traffic and has a steady tendency to increase the content of these toxic substances. We have proposed a way of disposal of the biomass of fallen leaves by the method of their biological degradation under anaerobic conditions
