GENERAL CHARACTERISTIC OF ABUNDANCE CHANGE IN AGRO ECOSISTEM OF ORGANIC GARDEN IN EXPERIMENTAL FARM “KUBAN”, KU-BAN STATE AGRARIAN UNIVERSITY

abstract 0510907017 issue 51 pp. 376 – 382 28.09.2009 ru 2964
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.
