  • Novel food sources have enormous potential as nutritional supplements. For instance, edible insects are considered as an alternative food source due to their higher protein content; moreover, they are economically efficient reproducers and have high in nutritional value. In this study, we investigated the toxicity of the freeze-dried powder of Locusta migratoria (fdLM), known to contain rich proteins as well as fatty acids. The objective of the present study was to evaluate the subacute toxicity of fdLM in male and female Sprague-Dawley (SD) rats. The SD rats were divided into four groups based on the dosage of fdLM administered: dosage of 0 (vehicle control), 750, 1,500, and 3,000 mg/kg/day were administered for 28 days. Toxicological assessments including observations on food consumption, body and organ weights, clinical signs, mortality, ophthalmologic tests, urinalyses, hematologic tests, clinical chemistry tests, gross findings, and histopathology tests were performed. Clinical signs, urinalyses, hematology, serum biochemistry tests, and organ weight examinations revealed no fdLM-related toxicity. The no-observed-adverse-effect level for fdLM was higher than 3,000 mg/kg/day in rats of both sexes; therefore, fdLM, in conclusion, can be considered safe as an edible alternative human and animal food source material.

  • Insects are the most successful organisms on earth in terms of their diversity and adaptability. Insect biotechnology using this insect resource is an emerging area for future biotechnology with various applications. Insect resources have long been used to make food and/or functional food, feed, cosmetics as well as medicine and industrial ingredients. Recently, one of the most well-known industrial material from insect is spider silk that could be commercialize in near future. The insect cell lines have been used to express recombinant proteins that were difficult to be functional expression. For public purpose, while, the insect could be good amenity source and plant farming, so leisure resource. Only the interdisciplinary research will guarantee the successful story for insect biotechnology. And biochemical engineers should used insect as a bioresource for new products with applications in medicine, agriculture, and industrial biotechnology in near future. This review will cover state-of-the art of this field and the research and application areas of insect biotechnology and the possible role of biochemical engineer for the development of the future biotechnology using this bioresource.

  • Functions of the building structures are recently expended, because the structures are getting larger and people's indoor staying times are getting longer. Therefore, various functional materials such as yellow mud, carbon soot, and jade are widely used. But functions of those materials have not permanent and continued an effect. Specially, the development of construction materials containing anti-insect is highly important to delight the environment of residence. This research try to examine to develop the mortar and concrete which contain microcapsules with long-term effect of anti-insect.

  • 이 연구는 식품원료로 등록되고 건강기능성 효능이 널리 알려지면서 생산과 수요가 점차 증가하고 있는 흰점박이꽃무지 유충의 사육환경 제어를 위한 식용곤충 스마트팜 공조시스템을 설계하여 제안하고자 수행하였다. 제안된 곤충 스마트팜 공조 시스템은 사육실과 공조실을 구분하여 사육에 최적화된 환경을 공조실에서 만들어 사육실로 보급하는 시스템으로 기존 곤충 사육농가에서 냉난방기, 가습기 등을 통한 환경 제어를 할 때 사육실 내 부분별로 온도 및 습도 등이 매우 상이하여 식용곤충을 판매할 때 균일한 크기 및 무게의 흰점박이꽃무지 유충을 생산하기 어렵다는 문제점의 해결책으로 제시될 수 있다. 곤충 스마트팜 공조 시스템을 사용함으로써 기존 곤충농가의 환경제어에 비해 온도의 차를 6℃, 습도의 차를 24.7%를 감소할 수 있으며 사육실 내 부분별로 온·습도가 다른 점을 개선하여 흰점박이꽃무지 유충의 사육 최적 환경을 계절에 상관없이 상시 제공함으로써 연중 생산을 통한 생산량 증대와 곤충 사육농가의 소득증대를 도모할 수 있다. 또한 제안된 곤충스마트팜 공조시스템은 설정된 최적 온도, 습도 및 CO2를 효율적으로 제어함으로써 갈색거저리 등 기타 식용곤충의 사육 및 버섯류의 생육에 필요한 환경제어 시스템으로도 활용할 수 있을 것이다.

  • Yellow mealworms (Tenebrio molitor Linnaeus) are very promising insects for the food and feed industry. Because mealworms are in the spotlight as an alternative protein source in the future, it is necessary to develop efficient rearing techniques for mass production. To evaluate the effects of brewer's yeast (BY) on the growth of mealworms, Tenebrio molitor Linnaeus, the mealworms were fed with wheat bran (WB) diets containing different levels of BY (0, 10, 30, 50, and 70%). Larval survival, larval weight, development time, pupal weight and eclosion rate were monitored for 12 weeks. The results showed that mealworms fed on the diets containing 30% and 50% of BY have significantly higher weight gain, specific growth rate and daily weight gain, and lower larval duration than fed the control diet (100% WB) and other BY diets (10% and 70% BY). Larval survival on the diets containing 30% and 50% of BY was higher than on control diet. Pupal weight and eclosion rate were not significantly different among all diets. In conclusion, we suggest feeding the diet containing 30% of brewer's yeast with wheat bran in order to increase the production of mealworms.

  • 흰점박이꽃무지(Protaetia brevitarsis) 유충은 동아시아에서 식용 및 약용으로 널리 사용되고 있다. 흰점박이꽃무지 수요 증가로 인해 유충의 대량 사육 방법이 필요하지만 좁은 공간에서 대량으로 유충을 사육할 경우 곤충 병원성 질병 감염에 취약해진다. Metarhizium anisopliae는 흰점박이꽃무지 유충에 치명적인 곤충 병원성 곰팡이 중 하나이다. 이를 저해하기 위해 항진균 성분이 함유된 옻나무(Rhus verniciflua Stokes) 추출액을 첨가하였고, 연구 결과 1% 옻나무 추출액을 첨가한 경우 녹강균에 의한 유충의 치사율이 유의미하게 낮았다. 또한 일반톱밥을 급여한 대조구에 비해 옻나무 추출액 처리구에서 유충의 무게가 더 무거웠고 유충 기간이 짧아지는 것을 확인하였다. 따라서 이 연구를 통해 곤충 병원성 곰팡이에 대한 옻나무 추출액의 항진균 효과를 확인할 수 있었으며 흰점박이꽃무지 유충 사육 시 옻나무 추출액을 첨가하여 급여한다면 병원성 곰팡이에 의한 유충의 치사율을 낮추고 증체량을 높이는 데 효과가 있을 것이다.

  • Insect-resistant transgenic rice (Bt-T) expresses a toxic protein (mcry1Ac1) derived from the soil bacterium Bacillus thuringiensis found in the rice cultivar Dongjin with an insecticidal property against rice leaf roller (Cnaphalocrocis medinalis). In this study, to investigate the impact of Bt-T on non-target organisms, the feed and oviposition preferences and biological parameters of brown planthopper (Nilaparvata lugens Stål) were comparatively analyzed in four rice cultivars: Dongjin (parent variety), Ilmi (reference cultivar), Chinnong (brown planthopper resistant cultivar) and Bt-T. In the Bt-T and Dongjin cultivars, the feed preferences were 32.4 ± 8.3 and 34.1 ± 6.8%, and the oviposition preferences were 32.5 ± 5.1 and 30.0 ± 5.3% respectively, and there was no statistical significance between these rices. Additionally, in the Bt-T and Dongjin cultivars, the total lifespans from egg to adult were 39.5 ± 6.9 and 40.0 ± 5.8 days, and the weights of adult females were 1.78 ± 0.14 and 1.72 ± 0.16 mg, respectively. Therefore, there was no statistical difference in the biological parameters between these two varieties. Overall, the results indicate that the insect-resistant transgenic rice (Bt-T) did not negatively affect the reproduction and life cycle of brown planthopper, a non-target organism.
