Abstract

The object of this research was to investigate the impact of an inclusion of Zn and/or Se in the growing substrate of black soldier fly larvae (BSFL). Concisely, five experimental substrates were formulated: I) A plant-based (Gainsville diet) control substrate (CTR); II) Okara and potato waste-based substrate (OkPa); III) OkPa-Zn enriched with 150 mg/kg of Zn; IV) OkPa enriched with 0.3 mg/kg of Se; and V) OkPa-Zn+Se enriched with 150 mg/kg of Zn + 0.3 mg/kg of Se. 500 BSFL were used for each diet and five replicates were set up. The larvae were reared under dark condition, at 26 °C with 60% RH and their growth performances analysed. The average weight of the individual larvae was not affected by the type of substrate (P>0.05). Contrarily, at the end of the trial the CTR group reached a significantly higher total larval biomass (P<0.05). The survival rate showed no difference between the experimental groups (P>0.05). These data indicate that okara and potato could be used in an appropriate substrate for BSFL breeding and that the inclusion of Zn and Se does not affect their growth performance. Further research is needed to asses the larval proximate composition, the micromineral adsorption and the reproductive performance of the resulting black soldier fly.
