This article determines the effect of temperature on humidity on the development of larvae, pupae and adults of different ages based on the sixth generation (F₆) of the edible insect Tenebrio molitor L. (Coleoptera: Tenebrionidae). The survival properties of young (<30 mg) and adult (<100 mg) larvae, pupae and adults of Tenebrio molitor (F₆) under the influence of relative humidity (RH) of 25, 50, 75 and 95% at a temperature of 10, 25, 35 and 40°C, respectively, for 6 to 48 hours. For moderate survival of young larvae (<30 mg) Tenebrio molitor (F₆), relative humidity 50-75% (survival 92-99%) at 10°C, relative humidity 50-75% (survival 100%) at 25°C, relative humidity 50-75% (survival rate 92-98%) at a temperature of 35°C is considered a favorable condition, while at a temperature of 40°C and a relative humidity of 25-95% for 12-48 hours showed 100% viability for 6 hours . All other relative humidity showed a sharp loss of viability at this temperature (viability from 76% to 38%). It was noted that adult larvae (<100 mg) of Tenebrio molitor (F₆) showed moderate relative humidity of 50–75% (viability 98–99%) at a temperature of 10°C for 6–48 h. At a relative humidity of 50%, the average survival periods of time was 95%, and with a relative humidity of 75%, the survival rate of 98.5% that is 3.5% more. It was found that for adult larvae (<100 mg) Tenebrio molitor (F₆), a relative humidity of 25–95% is convenient at a temperature of 25°C (viability of 100%). Adult larvae (<100 mg) of Tenebrio molitor (F₆) showed 100% viability, at 25-95% relative humidity for 6 h at 35°C, while larvae stored at 25% relative humidity for 12 h showed 92%, at 50-75% relative humidity they showed 100% viability, at 95% relative humidity showed 78% viability. It was noted that the average survival rate for all segments of relative humidity after 12 hours was 92%. It was noted that for the survival of adult larvae (<100 mg) Tenebrio molitor (F₆), a temperature of 40°C and a relative humidity of 25–95% give a stress effect (survival rate of 32%, 44%, 63%, 77%, respectively).
