Диференцiальна життєздатнiсть генотипних класiв зеленої дубової листовiйки залежно вiд генотипу кормової рослини

Abstract

The article is focused on the study of the influence of a genetic variation in DNA (RAPD-PCR, primer OPA 14) of oaks (Quercus pubescens L. and Q. petraea L.) on the survival of different Est-4 and Pts-4 genotype classes of the Tortrix viridana larvae. The obtained results show that individuals of the leafroller from the same genotype class may possess the maximal fitness (survival component) on trees of one genotype class and the minimum fitness on trees of another genotype class. The interaction of the “oak genotype” - “leafroller genotype” factors results in a rise of the ties, which are expressed in statistically reliable associations between the leafroller and oak genotype classes. The obtained results are discussed from the point of view of the newly developed field of community or ecosystem genetics and show the genetic-informative role of genoplast in their functioning.
