Savushkina I. Consortive ties of herbivorous insects in individual consortions of pubescent oak (heavy metal accumulation and migration, the role of genetic factors).

The objects are pubescent oak, herbivorous insects. The aim is to study according to a genotype of a core consortion the consortive relation of herbivorous insects in the individual consortion of an pubescent oak with the analysis of accumulations processes and migration of some heavy metals. The methods are atomic absorption, electrophoresis, polymeraza chain reaction, mathematical statistics. It is shown that in the individual consortions of pubescent oaks the processes of heavy metal migration from soil to oak leaves and then to the insect bodies are related to the genetic processes caused by the genotype of their determinants. The heavy metal contents as well as the compositions of herbivore micro-communities vary among individual oak consortions with different DNA fragments in their genotypes. In individual oak consortions the herbivore micro-communities consist of 13 species with the oak leafroller moth predomination. Application spheres are selection and training courses.
