Based on preliminary
results, approximately 10 kg of swine manure was placed
in a plastic tank (0.65 0.43 0.14 m) to a thickness of 5 cm and
exposed for biodegradation by 100,000 housefly larvae. Six replicates
were performed for this treatment. After 4 days of cultivation,
the third instars larvae were separated from residue by sieving,
dried at 105 C and ground for the next grease extraction.
