This study was conducted to evaluate the structure and composition (i.e., pH, moisture, total-N, pathogens, and volatile fatty acids) of broiler and duck manure treated with larvae of three insect larvae, namely, Tenebrio molitor, Protaetia brevitarsis seulensis, and Ptecticus tenebrifer. Hatched Tenebrio molitor (n=300), Protaetia brevitarsis seulensis (n=60), and Ptecticus tenebrifer (n=300) were used in this study; specially, the larvae were divided into six treatments with three replicates. The treatments were as follows: T1: 110 g broiler manure + Tenebrio molitor larvae (n=50), T2: 110 g duck manure + Tenebrio molitor larvae (n=50), T3: 125 g broiler manure + Protaetia brevitarsis seulensis larvae (n=10), T4: 125 g duck manure + Protaetia brevitarsis seulensis larvae (n=10), T5: 105 g broiler manure + Ptecticus tenebrifer larvae (n=50), and T6: 105 g duck manure + Ptecticus tenebrifer larvae (n=50). For all the larval treatments, the following results were observed: The moisture content of the duck manure treat with three insect larvae was higher than that of the broiler manure (p<0.05), whereas broiler manure had a higher pH (p<0.05). In addition, the total nitrogen content of broiler manure was higher than that of duck manure (p<0.05). However, the insect larvae did not significantly affect pathogens (E.coli and Salmonella) and the volatile fatty acids (p>0.05). In conclusion, the use of the three insect larvae to create organic nitrogen compost using poultry manure is feasible.
