On the basis of the achieved results the following can be concluded: survival of the yellow mealworm (Tenebrio molitor R.) at the larval stage was the greatest on wheat (86.50%) and corn (83.50%), further on the lentils (78.00%) and cookies (74.50%); the exceptionally small number of larvae which finished the development was on finely ground pastes (59.00%) and soybean (62.00%); by adding water or carrots to the soybean and finely ground pastes, the survival of the larvae increased; when the larvae were grown on wheat, the greatest number of larvae which developed into pupae was at the temperature of 25'C (88.00%) and 30'C (82.50%); at a relatively low temperature (20'C) or high temperature (35'C) the survival of larvae was low; moderate temperature of 25'C was the most suitable temperature for T. molitor since a total of 85.50% of this pest survived; mortality of T. molitor occurred at all development stages but it was higher at the larval stage than at the stage of pupa; mortality of larvae and pupae was under the influence of temperature and food.
