Agrobiocenosis

 

an association of organisms in the sowings and plantings of cultivated plants; one of the widespread forms of secondary biocenoses. Each species of cultivated plant forms its characteristic agrobiocenosis with a series of constant and dominant species. The agrobiocenosis is distinguished from the primary biocenoses by the incapacity for long-term independent existence as a result of the sharp weakening of the self-regulating processes; their temporary stability is supported by the activity of man. Another important property of an agrobiocenosis is the dominance of several herbivorous species of animals, primarily pests, particularly insects. A cultivated plant forms the energy base of the agrobiocenosis; this plant, together with the accompanying weeds, determines the composition of the animal population.
