The aim of this thesis was to find out whether selected types of food substrates affect the adult´s productivity, the weight of newborn nymphs and laid oothecas and whether changes in adult´s productivity and the weight of nymphs occur due to one source of food during the experiment. In this experiment, the Blaptica dubia, Nauphoeta cinerea and Schelfordella tartara species were used. The reason for selection of those species was their high rate of reproduction, undemanding breeding and a short period of growth. The experiment was conducted in six types of feed substrates. The cockroaches were kept at a room temperature. The scales accurate to 0,2 g were used for the determination of the weight (AVINET). The Blaptica dubia species proved the dependence of its adults´ productivity and nymphs´ weight on the month of observation and the dependence of nymphs´ growth on a feed. The Nauphoeta cinerea species proved the dependence of nymphs´ growth on a feed. The Schelfordella tartara species proved the dependence of its adults´ productivity and oothecas´ weight on a feed and on the month of observation. The results of this thesis could emphasize the importance of the influence of a feed on the life of cockroaches breeded in captivity and help breeders to their better results with regard to the selection of a suitable food.
