Insect industry has been focused as production of food, animal feed, pollinator and for environmental remediation. Hermetia illicens, called as black soldier fly (BSF) is famous as nutritive feed. In this study, to evaluate the antithrombotic activities of BSF, the larvae (instar 2~6), pupae, residue after adult emergence [RAAE] and adult of Hermetia illicens [black soldier fly, BSF] were collected and their ethanol extracts were prepared. Growth of BSF larvae was very rapid and the weight of larvae was increased to 25-folds during 10 days cultivation. The ethanol extraction ratios showed from 1.0% (pupae) to 18.5%(adults). The highest total polyphenol, total flavonoid, and total sugar contents were observed in RAEE (17.2 mg/g), pupae (3.4 mg/g), and instar 6 (37.6 mg/g), suggesting that metabolic changes occur during the life cycle of the BSF. Anti-coagulation assay showed that extracts of RAEE, instar 6 and pupa of BSF significantly inhibited thrombin, prothrombin, and blood coagulation factors. Furthermore, the extracts of RAEE, instar 3 and adult of BSF showed a strong platelet aggregation inhibitory activity. Our results suggest that pupae and RAEE of BSF have potential as antithrombotic agents. This is the first study to provide evidence of the antithrombotic activity of the BSF and bioactivity alterations during its life cycle.
