Simchuk A. The role of intraspecific heterogeneity in consortive ties of herbivorous insects from oak plantings in the Crimea: theoretic and applied aspects.

The objects are pubescent oaks and sessile oaks consortias, some their consorts of first and second concenters. The aim is to evaluate the role, which the intraspecific variability plays in ecological relations among the species-participants of individual consortia and some their groups on an example of oak, its insects-depredators, their entomophilies and micropathogens. It is shown that the participants of individual consortia are not uniform by their genotypes and phenotypes. This heterogeneity creates a situation when one species fits to other species, what is actually reflected in significant associations among genotypes or phenotypes of different species. Associative relations among the genophonds of interacting micropopulations in individual oak consortia create a genoplast, that plays a role of integrating driving subsystem. It regulates influxes of matter and energy throughout the trophic web, species composition of consorts in the Crimean oak forests. The genoplast plays the same role in agricultural ecosystems. The concept of genoplast is a base of the principally new approach to the pest control in agriculture, patented in Ukraine. Application sphere are ecology, agriculture and training courses.
