We have investigated the developmental characteristics of super mealworm on different temperatures. The test was conducted with four different temperatures of 25℃, 27℃, 30℃, and 33℃. In developmental period of 1 to 18 instars of four temperatures, 30℃ showed the shortest developmental period as 120.0±5.8 days, and 33℃ (132.6±10.7 days), 27℃ (136.5±9.2 days), 25℃ (156.7±7.5 days) in the following order. The death rate of 33℃ larvae was 2.7- 3.3 times higher than that of other temperatures. The lower temperatures tended to show the longer larval developmental period except 33℃. In the body weight, 30℃ showed the heaviest body weight and 27℃, 33℃, 25℃ in the following order. The head capsule, body capsule and body length also showed a similar tendency with body weight. The 88.8% of prepupa time of super mealworm was 16-18 instars. The longer prepupa time was accompanied by the lower temperature. In average prepupal period of 15-18 instars, 27℃ was 18.8±1.9 days, 18.8±2.3 days in 30℃, 23.0±2.4 days in 33℃, 23.1±2.9 days in 25℃. The average of pupal period of female and male in 25℃- 33℃ was 11.1±2.2 days and 11.6±2.4 days, respectively. In conclusion, the most suitable rearing temperature of super mealwarm was turned out as 30℃.
