This study considered the change in survival rate, body weight and fatty acid composition of mealworm during refrigerated storage. The mealworms were kept in refrigerator (temperature : 4.5±0.27°C, humidity : 22.1±0.64％) for 0, 10, 20, 30 and 45 days. The mealworms were 200 individuals per group and the three groups were prepared for each storage period. We measured the survival rate, body weight and fatty acid composition of mealworm for each storage period. Survival rate and body weight decreased with increasing refrigerated storage time. The proportion of unsaturated fatty acids and polyunsaturated fatty acids increased with increasing refrigerated storage time. Therefore, we need to consider that survival rate, body weight and fatty acid composition change with refrigerated storage time in case the mealworm is used as live feed.
