Abstract
An experiment was conducted to compare the suitability of chicken, pig, and cow manure as feed for larvae of the black soldier fly (Hermetia illucens (L.); Diptera: Stratiomyidae). Newly hatched larvae were inoculated on moistened manure (33% dry matter). Water and dried manure were added three times per week, until the first prepupae appeared. Survival was between 82 and 97%, indicating that the tested substrates were suitable. However, development time was much longer than on the control diet (144-215 vs 20 days). Efficiency of conversion of ingested nitrogen (N-ECI) was higher on pig manure than on chicken and cow manure, while the ECI for phosphorus was highest on cow manure. Substrate nitrogen content decreased in the chicken manure, but were stable in pig and cow manure. Phosphorus concentration, and N:P-ratio decreased in all treatments. Since a large proportion of the nitrogen from the manure (23–78%) was lost, the production system would require an air washer for instance, to make it ecologically sound. Shorter development times are required in order to improve economic viability. Drying of the manure could have decreased its nutritional value due to the destruction of microorganisms and heat-labile vitamins. A production system using fresh manure could result in a considerably shorter development time and increased conversion efficiency.

Personally I think they're missing the point by using dried manure alone. Think of all of the liquid waste streams that we currently have no viable means to recycle - waste blood, waste milk, waste dishwater from commercial kitchens. These things can be mixed with absorbant materials and the BSF will eat the lot. I've seen them eat paper before when it's soaked with juices.
