Abstract

Ivantsova, E. A., V. V. Novochadov; N. V. Onistratenko, M. V. Postnova, 2017. Ecological aspects of phytosanitary optimization of arid agrobiocenoses of the south of Russia. Bulg. J. Agric. Sci., 23 (5): 834–842

In the article features of phytosanitary situation in the agrarian sector of industry in the South of Russia are considered. The mechanisms and degree of influence of economic and environmental factors on the state of farmland, their infection with insect pests are revealed. The structure and dynamics of entomo-communities in arid agrocenoses of the region are analyzed. The effect of complex biopreparations in the system of agrotechnologies aimed at regulating the life activity of agrobiocenoses has been studied. New paths of optimization of scientifically based system of agrotechnical methods of management of agricultural ecosystems in arid conditions of the Lower Volga region are proposed.

Key words: aridization; insects’ wreckers; protection of plants; entomopathogenic microorganisms; arrangement of a landscape
