TAILIEUCHUNG - Biodegradation eichhornia crassipes of black soldier fly larvae (Hermetia illucens) based on growth rate and food comsumption

Water hyacinth (Eichhornia crassipes) is recognized as an invasive species in numerous countries. Black solider fly larvae (BSFL) or Hermetia illucens is a common and widespread fly of the family Stratiomyidae, whose larvae are common detritivores in compost heaps. In this study, 6 day old BSFL were fed with the food which were water hyacinth and residues after BSFL grew on organic waste from domestic waste which contains bacteria producing enzymes from gut of BSFL. | Trịnh Thị Bích Huyền và Đtg Tạp chí KHOA HỌC & CÔNG NGHỆ 139(09): 131 - 136 BIODEGRADATION EICHHORNIA CRASSIPES OF BLACK SOLDIER FLY LARVAE (HERMETIA ILLUCENS) BASED ON GROWTH RATE AND FOOD COMSUMPTION Trinh Thi Bich Huyen*, Nguyen Ngoc Mai Trinh, Ngo Thi Kim Cuc, Lam Pham Thanh Hien, Dang Vu Xuan Huyen, Lai Duy Phuong, Dang Vu Bich Hanh Hochiminh city University of Technology SUMMARY Water hyacinth (Eichhornia crassipes) is recognized as an invasive species in numerous countries. Black solider fly larvae (BSFL) or Hermetia illucens is a common and widespread fly of the family Stratiomyidae, whose larvae are common detritivores in compost heaps. In this study, 6 day old BSFL were fed with the food which were water hyacinth and residues after BSFL grew on organic waste from domestic waste which contains bacteria producing enzymes from gut of BSFL. The ratio of water hyacinth and residues in 4 models were 1:0; 1:1; 2:1; 3:1, respectively and control model (which BSFL were fed with organic waste from domestic waste). The parameters such as weight, size and protein content of BSFL, food residual were measured every 3 days or 4 days until BSFL reached 30 day old. Results showed BSFL were able to survive and grew in the model 1:0 in which the food was only water hyacinth, but the BSFL had the lowest growth rate of after 24 days of feeding. In addition, model 1:1 showed that the highest growth rate of BSFL was after 24 days of feeding. In model 1:1 with the weight rising larvae was high (), in which was converted to protein content of the larvae, commensurate with water hyacinth consumption of . The study found a method of treatment of this invasive plant species. Simultaneously, this process creates a protein-rich food source for animals. Therefore, BSFL should be used to treat water hyacinth to produce a protein-based feedstock, contributing to sustainable development. Keywords: black soldier fly larvae, water hyacinth, .
