| Summary: | 碩士 === 國立中興大學 === 昆蟲學系所 === 106 === The black soldier fly (BSF; Hermetia illucens L.; Diptera: Stratiomyidae) larvae can degrade a wide variety of organic material, such as vegetable and fruit, food waste, human and animal manure, etc. Thus, it has seen a potential biomass decomposer to reduce various types of organics and to convert these waste organics into biomass with rich protein and fat. During the agriculture production and food processing procedure, many agricultural and food by-products can be produced also. However, large amounts of the by-products are not properly used and lots of them still contain high nutrients. Although BSF larvae had been found to be able to decompose some organic by-products, there is limited understanding about how the BSF can decompose the materials more effectively. Therefore, the objective of the present study was trying to find out the way to increase the efficiency of food utilization by various ways. In this research, the probiotic supplements were added to different diets to observe the effects on the development performance and nutritional value of BSF larvae. Artificial diet and some by-products of organic as the main diet were used in this study. Then, extra probiotic and carbohydrates were added to the diets to compare whether they would affect the developmental performance of BSF larvae. The results suggested that BSF larvae performed better on the artificial diet than those fed on by-product diets. The larvae fed on diet contained probiotic Bacillus amyloliquefaciens, FB1 contained crude protein and crude fat content as high as 64% and 47%, respectively. However, results of this study also revealed that the ability of decomposing by-product diets by BSF was as high as 70%. Especially at larvae fed on the by-product diet mix with pineapple peel had shorter developmental time (from 30 days to 21 days) and higher survival rate (from 39% to 88%). This result indicates that the decomposition capacity of organic by-products by BSF is quite compatible to that on artificial diet. In the future application of using BSF for organic by-products decomposition, food safety should be considering first and also need to fulfill the aim to reduce the cost-effectiveness of large-scale insect rearing industry. To obtain a large amount of BSF biomass in a short period of time, extra carbohydrates would be suggested to add in the diet. Finally, further research is needed to complete the nutritional composition analysis of BSF which is able to confirm the potential of this insect as new animal feed additives.
