The paper shows the possibility of using various substances with insecticide to reduce the norms of the drug per unit area. Preparations Sumi-alpha and Kurakron in full and half-norms jointly and severally with the subsidiary additives slightly altered physico-chemical properties of solutions. Oils increases the toxicity of solutions.

Results about invasion activity of 3 kinds entomopathogenic nematodes from family Steinernema (S. feltiae, S. carpocapsae, S. glaseri ) concerning 2 pest insects of a cotton (cotton scoops Spodoptera littoralis and a cotton bug - Pectinophora gossypiella) and house fly (M. domestica) is analyzed. It is found that the greatest efficiency in the relation larvae stages of pests is S. feltiae. Pupae, in general, were less susceptible to nematode infestation.

The 10 min UV-B irradiation (12 dj/m2) and 100mM NaCl action on medical plants Ocimum basilicum L., grown in water culture, was studying. The plants treated by UV-B irradiation were more resistent to salinity. There were two groups of compounds. One - proline, carotinoids, phenols are accumulated under salinity conditions. Second group - pigments - antocyans and flavones. Its biosynthesis is stimulated by UV-B irradiation. Under complex stressor action pigments were increased and this increasing helped plants to overcome the high salinity. The antioxidant enzyme superoxid dismutase did not play essential role in adaptive response. The low molecular weight antioxidants were more effective for formation of adaptation response. The peroxidase activity had not correlation with superoxid dismutase activity and we supposed that H2O2 could be result of other process and served as signal molecul.

The information about domestication and area: of settlement (natural habitat) of such agricultural animals as cows, goats, sheep, horses and pigs is given in the article. For primitive people animals meant to be preys for life support. To make the hunt successful, primitive people scrutinized animals'habits, which they thought, were quite similar to theirs. The human believed that he descended from the animal. Religious belief in animals-forefathers is called totem. There appear the myths, where various animals and birds act. Animals became visible images of gods and they were endowed with the capacity to turn into gods-humans, who, at the same time, could become animals, understand their habits, speak their language. Religiously mystic studies about reincarnation are known as metempsychosis.
