| Abstract | Black soldier fly (BSF), Hermetia illucens (L.) (Diptera Stratiomyidae), is a saprophagous insect that is receiving a growing scientific and economic interest since during the larval stage it is extremely voracious and able to consume a wide range of organic materials. This ethological characteristic is particularly suitable for waste management at industrial scale. The extraordinary ability to accumulate high levels of proteins and lipids, allows the use of resulting larvae as animal feed or biodiesel production; the residue of the bioconversion process, that consists of larval frass and not converted organic matter is assimilable to organic fertilizer. The aim of this study was to evaluate the bioconversion process by black soldier fly larvae (BSFL) on fresh and mature dairy manure. A "mobile bioconversion unit" that works as a mobile breeding unit was used, allowing to carry out bioconversion tests directly on fields, in different livestock farms located on the Basilicata territory (Italy). Total larval and frass biomass, bioconversion yield, BSFL development time and substrate reduction were evaluated for each treatment. All the analysed parameters differed from the control (larvae fed in standard diet) but not between the two substrates from the zootechnical chain. Although development time significantly differed across treatments, BSF correctly grow and reduce all substrates confirming larvae can be used to bioconvert animal manure reducing the undesired effects occurring from mismanaged this kind of substrate. |
