In natural conditions, the black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae), colonizes in warm temperate regions, and is active in Korea from May through October. Information on black soldier fly rearing, which is affected by seasonal factors in Korea, is limited. This species colonizes and oviposits in a wide variety of decomposing vegetable and animal matter. For mass rearing of black soldier flies, the egg deposition methods are dependent on sunlight and oviposition sites. In this study, we investigated the substrates and oviposition sites preferred by black soldier fly in artificial rearing system. Our results showed that as black soldier flies prefer mating under sunlight, they prefer ovipositing at sites where adequate sunlight and food substrate are available. Further detailed research is required to develop methods for artificially rearing black soldier fly throughout the year in Korea.

The black soldier fly, Hermetia illucens, has a worldwide distribution in the tropics and warm temperate regions and is active in the Korea from May through October. This species colonize a wide variety of decomposing vegetable and animal matter and oviposits in a variety of decomposing materials. In this study, how the black soldier fly pupation, adult emergence and mating rate changed with season at the artificial rearing system was investigated. The black soldier fly larvae and pupae were reared under laboratory condition ($27^{\circ}C$, 60% R.H.). In this study, under the laboratory condition, pupation and adult emergence were not influenced by season, but the data shows definitely different mating numbers throughout whole year. The time of the day is changed with seasons and it influence to mating on artificial rearing. To culture the black soldier fly throughout the year in Korea needs a more deep study under the artificial rearing system.

최근 곤충자원을 이용하여 식약용 및 사료로 활용하기 위한 많은 연구가 진행되고 있으며 미래의 자원으로 발전할 수 있는 가능성이 충분하다고 본다. 특히, 대량으로 생산이 용이하고 유충과 번데기의 조단백질 및 무기물 함량이 우수한 아메리카동애등에는 양계 및 양어사료의 원료로써 사용 가능성이 높게 평가되고 있다. 본 연구는 아메리카동애등에의 유충 및 번데기의 항산화 활성을 비교 평가하였다. 아메리카동애등에 번데기의 물 추출물의 경우 DPPH 라디칼 소거능이 $147.8{\pm}1.6%$로 양성 대조군으로 사용된 Vitamin C(5 mg/mL)의 $109.0{\pm}0.15%$와 메뚜기의 $109.5{\pm}28%$ 보다 높은 활성을 나타내었다. FRAP을 통한 환원력 측정에서도 DPPH 결과와 마찬가지로 아메리카동애등에 번데기의 물 추출물에서 가장 높은 환원력을 나타내었다. 위의 결과로 보아, 아메리카동애등에 유충 및 번데기의 추출물은 라디칼 소거능 및 산화환원작용을 통하여 항산화 활성을 가지는 것으로 사료되며, 특히 번데기의 추출물은 천연 항산화 소재로서의 활용가능성이 높은 것으로 기대되었다. 추후 추출물의 산업적인 활용가능성을 보다 명확히 확인하기 위하여 보다 많은 연구가 필요할 것으로 본다.

Background: The black soldier fly (Hermetia illucens) is gaining attention as an efficient decomposer of food waste. However, recalcitrant compounds such as plastics mixed into food waste may have negative effects on its growth and survival. Moreover, its efficiency of food waste degradation may also be affected by plastics. In addition, salt (NaCl) can also be present in high concentrations, which also reduces the efficiency of H. illucens-mediated food waste treatment. In this study, we assessed the growth of black soldier fly larvae (BSFL) reared on food waste containing polyethylene (PE) and polystyrene (PS) and NaCl. The weight of BSFL was measured every 2-4 days. Survival and substrate reduction rates and pupation ratio were determined at the end of the experiment. Results: The total larval weight of Hermetia illucens reared on food waste containing PS was greater than that of the control on days 20 and 24. However, the survival rate was lower in the group treated with 5% PS, as was substrate reduction in all PS-treated groups. The weight of BSFL reared on food waste containing PE was lower than that of the control on day 6. PE in food waste did not affect the survival rate, but the pupation ratio increased and substrate consumption decreased with increasing PE concentrations. Regardless of the plastic type, the addition of NaCl resulted in decreased larval weight and pupation ratio. Conclusions: Larval growth of black soldier fly was inhibited not by plastics but by substrate salinity. Additional safety assessments of larvae reared on food waste containing impurities are needed to enable wider application of BSFL in vermicomposting.

본 시험은 붕어에 대하여 동애동에의 살아있는 유충과 건조된 유충 및 번데기의 공급 사육시 성장에 미치는 영향을 조사하기 위하여 약 16주간 사육하면서 어체의 증체율 및 길이성장을 비교 조사하였다. 사료로 사용하기 위한 성분분석에서 건조 유충과 번데기의 조단백질 함량은 43% 이상 수준으로 나타났으며, 지방산 분석결과에서 불포화 지방산의 함량이 상대적으로 높게 나타났다. 이는 양어사료의 단백질 및 필수 지방산 공급원으로 좋은 원료로 사용 가능 할 것으로 사료된다. 약 16주간 동애등에를 붕어먹이로 공급하여 어체의 증체율과 길이에 미치는 영향을 조사한 결과는 살아있는 동애등에 유충을 공급한 실험구에서 증체율과 길이의 증가가 가장 크게 나타났다. 양어사료만을 공급한 실험구와 양어사료에 건조한 유충과 번데기를 50% 혼합하여 공급한 실험구의 증체율 및 길이의 증가를 비교해 보았을 때 건조한 유충과 번데기를 혼합하여 공급하는 것이 효과적인 것으로 나타났다.

The use of insects as a food source is not a new idea, but it has gained momentum in recent years due to the need for sustainable protein source in livestock feedstuffs and for more environmentally friendly organic waste treatment. In the case of black soldier fly larvae, Hermetia illucens, research has focused on their ability to convert organic waste into usable nutrients and their potential as a protein source for animal and human consumption. In this study, black soldier fly larvae were reared on raw food waste (FW) mixed with garlic peel waste (G) and hydronic growth media waste (H) and the proximate composition and bioactive potential of black soldier fly larvae extract (SFL) were compared. Analysis showed that protein content of SFL fed with G was 4.21% higher and lipid content was 9.93% lower than FW. Similar results were obtained for SFL fed with H. Antioxidant activity of SFL-G was higher than that of SFL-FW and SFL-H. SFL-G treatment exhibited enhanced anti-inflammatory and anti-adipogenesis activities as well compared to SFL-FW. Current results suggested that feeding black soldier fly larvae with food waste added with garlic peel and hydroponic growth media waste resulted in increased nutritional value, polyphenol content and bioactivity for SFLs. In this context, garlic peel waste-added food waste was suggested a promising substrate for black soldier fly larvae to obtain high-quality protein source with enhanced antioxidant, anti-inflammatory and anti-adipogenic potential.

Under natural conditions, black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae), colonizes in warm temperate regions, and is active in Korea from May through October. Information on black soldier fly rearing, which is affected by seasonal factors in Korea, is limited. Oviposition by black soldier flies is dependent on light intensity and wavelength. Therefore, continuous mass rearing of this fly requires determination of optimal artificial conditions of illumination. In this study, we compared the number of eggs laid under an artificial light source (750 watt HPL lamp) versus nature sunlight. Our results showed that compared to oviposition under natural sunlight, the use of one or two lamps for 7 hours, resulted in only 43 and 76%, of the total number of eggs laid under natural sunlight, respectively. We also investigated the hatchability of oviposited eggs under artificial illumination and under natural sunlight. The hatching rate under the former was much significantly lower than under the latter. Further detailed research is required to develop methods for successful mass rearing of black soldier fly throughout the year by means of an indoor system.

The era of mass production of agricultural and dairy systems inevitably causes a huge amount of biowastes during their processes. Modern consumption patterns of the general public also contribute to biowaste formation. Thus, processing biowastes has attracted much attention. The introduced black soldier fly (BSF) (Hermetia illucens) is considered as one of environmentally friendly management options for solving biowaste issues. However, an indigenous species, Ptecticus tenebrifer, is also a powerful decomposer that has been largely neglected. This species can be easily found on biowastes such as manure dump, agricultural wastes, and human food wastes. It can be also easily found in the field. It is even attracted to a food trap. To the best of our knowledge, this is the first ecological study on this species.

Most studies of the black soldier fly, Hermitia illucens, widely distributed throughout Southeast Asia and America focused on the use of larvae for recycling various organic materials and feed for fish and livestock. To recognize the instars of the soldier fly's larvae, we examined the number of exuviae originated from each larva from 1st instar to pupa. The weight and the head capsule width of the black soldier fly larvae also confirmed that the black soldier fly was passed through 6th instars. In addition, we found that the black soldier fly larvae had a well developed mandibular-maxillary complex, similar to those reported from the larvae of scavengers including Odontomyia cincta, Neopachygaster maculicornis, Ptecticus brunettii and Stratiomys ruficornis.
