The subject of this study was the lesser grain borer Rhizopertha dominica F. The aim of the experiments was to verify the hypothesis suggesting that the course of simultaneous vertical migration and horizontal spread of the R. dominica population is determined by nutritional and habitat selectivity. The following products were used as nutrients in the experiments: wheat, oat flakes, pearl barley and semolina. It was found that the course of a migration process is connected with nutritional preferences determined mainly by a nutrient type and its granulation. At the initial stage of the study the highest emigration was noted in the oat flakes. After a time the highest migration was directed to as follows: wheat, oat flakes, pearl barley and semolina. Females showed a higher migratory activity.

The subject of the study was the lesser grain borer Rhizopertha dominica F. — a dangerous pest of stored grain. The study was carried out in the laboratory at a temperature of 31°C, the optimal temperature for this species, and also in the temperature lowered to 22°C and 60±5% relative humidity. The main aim of the research was to investigate the migration activity of R. dominica in lowered temperature. In addition the population dynamics, mortality and sexual ratio in a population of R. dominica were also analyzed. It was shown that lowering the temperature to 22°C caused an increase in the migration activity of R. dominica in the initial phase of infesting a new habitat. A larger migration and mortality of females were observed. In addition, the population growth was slow and prolonged in time at the temperature of 22°C as compared to the optimal temperature. Lowering the temperature did not influence the mortality of the R. dominica population.
