“…The pH changed from neutral to alkaline (around 8.7). Zhu et al (2015); Zhu et al (2012) found the same result during the biodegradation with the housefly larvae.…”

“…At this same stage, the substrates with the highest larvae weight (pig, poultry, mixture of poultry and sheep, mixture of poultry and cow, mixture of pig and sheep substrates) showed low organic carbon decrease(around 8%). Zhu et al (2012) and Zhu et al (2015) also recorded about 8% decrease of carbon in the pig substrate respectively after seven and six days of biodegradation by the housefly larvae. They justified this result by the low degradation of carbon macromolecular chains by the fly larvae before to reach its cycle.…”

“…Čičkováet al (2012 demonstrated that Muscadomestica, the most frequently found species reduce 1 kg of pig dejectionto 0.18 kg. Zhang et al (2012), Zhu et al (2012), Zhu et al (2015) and Wang et al (2016) reported also an important loss of carbon and nitrogen in the swine manure after housefly (Muscadomestica) larvae production. Such potential of housefly can be harnessed in rural areas under the tropical conditions, especially in Sub-Saharan Africa.…”

“…Those changes were mainly due to the crawling and the digestion by the fly larvae which increased the pore of the material and also improved the metabolism of the micro-organisms in substrate (Zhu et al, 2015). The temperatures recorded during the process were below40°C indicating that the biodegradation of the substrate from animal residues by Musca and Calliphoralarvae in free ovipositor system is occurring in mesospheric phase.…”

“…Thus, to accomplish their metabolism, fly larvae breakdown the organic residues resulting to the carbon reduction (as CO2 form), nitrogen decrease (as N-NH4 + and N-NO3 -), and the substrate's weight reduction. Several studies reported these changes during the substrate degradation by the fly larvae compared to the underrated substrate (Barnard et al, 1998;Zhu et al, 2012;Zhu et al, 2015;Wang et al, 2016). Cow and sheep substrates registered the highest organic carbon decrease (around 35%) during the first stage of biodegradation process.…”

Our study aims to assess physical and chemical properties of organic residues decomposed by fly larvae to be promoted as organic manure. Three stages of four days duration each of biodegradation of 12 various animal substrates (pig, poultry, guinea fowl, sheep, cow, mixture of pig and sheep substrates, mixture of pig and cow substrates, mixture of poultry and sheep substrates, mixture of poultry and cow substrates, mixture of guinea fowl and sheep substrates, mixture of guinea fowl and cow substrates) using Muscadomestica and Calliphoravomitoria larvae were performed. Temperature, pH, weight, organic carbon, total nitrogen, nitrite and ammonia contents during decomposition process were data collected. The highest temperatures were recorded respectively in the pig and poultry substrates. The pH changed from neutral to alkaline. Organic carbon content reduced during the biodegradation process and was positively correlated with reduction of substrate's weight. Significant decrease of ammonia content was recorded respectively during the first, second and third stages of biodegradation process in the poultry substrate (80, 46 and 61%), guinea fowl (77, 26 and 27%) and pig substrate (76, 66, and 40%). Furthermore, nitrite content was low ranging from 0.0033 to 0.075 gkg -1 . The stability and maturity of the final product were high with pig substrates, mixture of poultry and sheep substrates, mixture of poultry and cow substrates, mixture of pig and sheep substrates. It is suggested to give priority to the later substrates for soil fertility management.
