Balykina O. Features of formation enthomoacarological complex of apple orchards and the system of their control in the Crimea.

Ecological laws of formation, development of enthomological complex and regulation of quantity of dominant phytophagus in apple orchards of different age has been theoretically generalized and motivated. Five stages of formation of apple orchards enthomoacarocomplex have been distinguished. Four main groups of ecological niches and complexes of pest connected with them have been determined. Biodiversity of pest and mites reaches its maximum in orchards of 14-20 years old. The enthomoacarocomplex of apple orchards in the Crimea during last ten years presented by 62 species (37 phytophagus and 25 enthomoacarophagus) has been determined. For the first time in the Crimea the development of the third generation of San gose scale and apple morth has been marked. The three years periodicity of quantity fluctuation of Sciaphobus squalidus Gyll. connected with diapause has been established. The optimal terms for application of modern insecticides were determined. The possibility of regulation of apple morth quantity by method of male disorientation has been established. For the first time the system for apple pests management in the Crimea adapted for trees of different age and type of cultivation has been motivated and improved.
