The most suitable temperature for Dubia is 25-30 ℃, and the relative humidity is 60-75%. The growth cycle shortens as the temperature increases. When the insect density is high during the feeding process, more heat is generated due to the mutual friction between the insects, and the actual body temperature of the Dubia larvae is higher than the room temperature. The temperature has a significant effect on the weight gain and death of the Dubia larva. Too high or too low is not conducive to the growth and survival of Dubia roaches.
