Критерии оценки адаптации Aphidoletes aphidimyza rond. (Diptera: Cecidomyidae) в условиях биодинамического земледелия
Abstract
The paper presents the results of studies of the effect of nano aqua citrate of microelements (Se + Ge) with biologically active components on the combined changes in the body of Aphidoletes aphidimyza Rond. When supplemental nutrition is used, the optimum concentration of nano aqua citrate of microelements (Se–0.0005 + Ge–0.0003) – 0.0008 mg/dm3 with the biologically active components – 65 mg /dm3, the survival increases to 89%, the fertility to 98%, the reproductive capacity(Rp ) of females to 64.5%. It has been established that during the modification of trophism, positive changes occur in the biology of the aphidophage, and the competitive capabilities of Aphidoletes aphidimyza Rond. are improved as a biological agent of limiting the harm of the members of the Aphidoidea superfamily. The proposed elements of the technology of reproduction and practical application of Aphidoletes aphidimyza Rond. are characterized by high economic efficiency (25%) in the conditions of the protected soil. The aim of the research was to study the possibility of using nano aqua citrate of microelements (Se + Ge) with biologically active components for the correction of the life cycle of Aphidoletes aphidimyza Rond. To achieve this goal, the following tasks were solved: on the basis of trophic relationships in the phytophage – host – aphidophagus system, to carry out the analysis of the functioning of resistant adaptive systems Aphidoletes aphidimyza Rond. in the conditions of agrobiocenosis.
