Survey on the rearing process of Black Soldier Fly (Hermetia illucens) larvae using organic by-products

Abstract

    Black Soldier Fly (Hermetia illucens) larvae have the capability to grow and effectively process various types of organic substrates. This study investigates the growth and development of Black Soldier Fly (BSF) larvae using organic by-products from wholesale markets in Ho Chi Minh City. The substrates were mixed in a ratio of 85:15 between Chinese mustard greens and pineapple peels (1:1) with soybean residue, fish entrails, chicken bran, and a control of 100 % Chinese mustard greens and pineapple peels (1:1). These substrates were ground and treated with microorganisms. The results showed that BSF larvae could grow and develop on these substrates. Among them, the 85:15 mix of Chinese mustard greens and pineapple peels (1:1) with fish entrails resulted in the highest survival rate of 94.02 %, while the substrate with only Chinese mustard greens and pineapple peels (1:1) had the lowest survival rate of 70.64 %. This study provides important data to optimize the process of rearing BSF larvae, aiming to apply it to the treatment of organic by-products from wholesale markets in Ho Chi Minh City. It also contributes to reducing organic waste, minimizing environmental pollution, promoting a circular economy, and sustainable development.
