Ecological impact of biotic factors on the natural ecosystem during agricultural cultivation of Lonicera caerulea in Central Russia

Abstract

The aim of the study is to search for the influence of biotic factors in the agrocenosis with edible honeysuckle (Lonicera caerulea L.) on the state of forest woody plants in natural phytocenosis. A nursery of the N.V. Tsitsin Main Botanical Garden of the Russian Academy of Sciences (Moscow) and natural biocenoses, including coniferous and deciduous trees, was a place of research in the regions of Central Russia in the period of 2005-2020. More than 50 phytophages and phytopathogens on edible honeysuckle plants in the monitoring process were noted. Complex biotic relationships with numerous trophic connections are formed between the agrocenosis and the natural ecological system was revealed. The polyphages Lepidosaphes ulmi L., Parthenolecanium corni Bouche, Chionaspis salicis L., Phenacoccus aceris Bouche, and Tetranychus urticae Koch are especially active in this system, creating environmental problems of various levels. It is noted that nonspecific phytopathogens are dangerous for artificial and natural cenoses, especially Neonectria ditissima (Tul. & C. Tul.) Samuels & Rossman, Nectria cinnabarina (Tode) Fr., Phellinus conchatus (Pers.) Quél., and Fumago vagans Pers. that formed food chains with weakened plants. The rules of plant care and protection are necessary to follow to preserve natural populations and obtain a good harvest in berry nurseries.
