Abstract

This study was conducted to evaluate the effects of using Hermetia illucens larvae as environmental purification insects on ammonia and Hanwoo manure for 15 days in the Hanwoo farms. H.illucens larvae were allocated into four treatment groups and three replicates using a randomized block design. The treatments were as follows: control, normal 1000 g of Hanwoo manure, T1, 1000 g of Hanwoo manure + 100 g of 2nd instar H.illucens L. larvae, T2, 1000 g of Hanwoo manure + 100 g of 3rd instar H.illucens L. larvae, and T3, 1000 g of Hanwoo manure + 100 g of 4th instar H.illucens L. larvae. After 0 days, ammonia fluxes did not occur in the 2nd, 3rd, and 4th instar H.illucens larvae treatments (p<0.05). Among the characteristics of Hanwoo manure, the pH and nitrogen content increased for each larvae instar of H.illucens, whereas ADF and NDF content decreased (p<0.05). In particular, nitrogen contents were found to be highest in the 3rd instar larvae of H.illucens owing to their greater ability to decompose Hanwoo manure than larvae at other growth stages.
