Influence of the individuality of fodder plant on the variability of adaptively important features of the oak leafroller moths and its interaction with parasites

Abstract

The paper is addressed to the investigation of the influence of individual properties of a fodder plant Quercus pubescens Willd. on the variability of fitness-important features in genotype classes of oak leafroller moths Tortrіx vіrіdana L. and on the moths’ interaction with parasites. The interaction of the factors describing the pubescent oak individuality and the leafroller genetics contributes up to 22 % in males’ and 42 % in females’ total variability of the fitness-important features. Parasite Itoplectis maculator F. chooses the leafroller pupae in dependence on their sizes. Specific features of particular fodder plant determine this selective choice in relation to alternative genotypes of the oak leafroller moth.
