Abstract
Inheritance of morphological characters related to male and female genitalia was examined in Archips podanaScop. The position and number of aedeagus prongs had a monogenic diallelic mode of inheritance. The gene determining this character is autosomal. Homozygous and heterozygous males have respectively one and two prongs. 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-11-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.
