Hermetia illucens is one of many of solider flies and the species was decomposing ability to food waste, livestock feces and so on. Specially, the study was conducted to investigated of artificial feeding using the livestock feces, because of easy to get and see in a rural areas. But, comparing food waste with livestock feces, the growth character of H. illucens was generally small size and the growth period is longer than feeding food waste. In order this problem, the experiment was performed by mixing sugar 1%, 5%, 10%, 20% , which can accelerate the degradation of the pig and cattle feces during the 0, 3, 5, 7 days. As a result, when the width and length of H. illucens were compared by sugar mixing and fermentation period, they was no significant difference. Decomposing ability of a larvae were 0.44g with cattle feces+sugar 5% than 20% and were 0.64g with pig feces+sugar 20% than 5%.
