Ivashov A. Consortive interactions of oak leafroller moth (Tortrix viridana L.): theoretical and applied aspects.

Research subjects: oak leafroller moth (Tortrix viridana) from the Tortricidae family, its host plants: sessile (Quercus petraea) and pubescent (Quercus pubescens ) oaks, and its parasites. Research objectives: To investigate ecological, biochemical, genetic and phenetic regularities of consortive relationships of Tortrix viridana. Methods: Phenological studies, thin-layer chromatography in polyamide, DEAE- cellulose, trypsin-agarose and sephadex G-50 column chromatography, enzyme-electrophoresis in polyacrylamide gel. Theoretical and practical results: adaptation of oak leafroller moth caterpillars to plant defense factors were studied in individual consortions of oak trees. Novelty of introduced: It was defined a stochastic nature of genoplasts in individual, parcellar and populational oak consortions, which revealed in statistically significant genotypic and phenytic assotiations between the consortion participants. It was formulated a conception of pesticide-free control oak leafroller moth and oth er forest pests in recreational zones of the Crimea. It assumes reasonable combination of natural regulating mechanisms and forest management. Implementation degree: The results of investigation are using as a part of courses "General ecology" and "Population ecology", which are addressed to the students specializing in the department of ecology of Tauria National V.I. Vernadsky University. Effectiveness: The results promote the notions on consortion, open new direction in study of consortions, develop theory of genoplast, change the pesticide-free strategy of forest protection in recreational zones of the Crimea. Sphere, sector of implementation: botany, protection of nature, agriculture, zoology, ecology, forestry, biological plant defense.
