The lesser grain borer (Rhizopertha dominica F.) belongs to insects, which cause the highest and most severe losses in stored products. Therefore, the aim of this experiment was to determine the effect of the technological properties of three different wheat cultivars on the development of this insect species. The material for the study consisted of grains of three wheat cultivars: Figura, Kampana and Komnata. The experiment was carried out under fixed conditions: 30°C and 75% humidity. Statistically significant effect of all the analyzed factors and their mutual interactions on the analyzed parameters was shown, except a wheat cultivar factor, which proved to be non-significant in respect to the abundance of new generation of beetles. The cultivar Kampana, classified as class C wheat, i.e. fodder wheat, proved to be susceptible to feeding by the lesser grain borer.
