[Genetic bases for heterogeneity of a population of omnivorous Archips podana Scop. leaf roller moths (Lepidoptera: Tortricidae) by morphological and behavioral traits].
Inheritance of morphological characters related to male and female genitalia was examined in Archips podana Scop. The position and number of aedeagus prongs had a monogenic diallelic mode of inheritance. In contrast to homozygous for P1 (prong A) and heterozygous (prong A + B) males, males homozygous for P2 (prong B) were characterized by much more active courtship. The gene correlates with a set of characters controlling individual ecology, exploring behavior of females, and feeding on different cultures. Morphological adult type 0 is an extremely weak form of phenotype B. Exploring activity of adults having phenotype B is the highest at the ratio of cis-tetradecenol to the other components of the female sex pheromone that leads to a somewhat lower activity of males of other phenotypes. In females, no regularities in inheritance of phenotypic characters were revealed. A hypothesis on a mechanism for maintenance of population stability for the given phenotypes is advanced and a possible mechanism for microevolution of a polymorphic species is proposed.
