최근 국내 양잠산업은 의류중심의 전통적인 양잠산업에서 기능성 양잠산업으로 변화를 꾀하고 있다. 이런 여건변화에 대응하기 위해 2009년에 "기능성 양잠산업 육성 및 지원에 관한 법률"이 시행되어 기능성 양잠산업 종합계획 수립 근거가 마련되었다. 기능성 양잠산업 발전을 위한 종합계획을 수립하기 위해서는 현재 양잠산업의 실태와 문제점 파악이 선결되어야 할 것이다. 본 논문의 목적은 양잠산물의 생산 판매구조와 산업 분야별 애로요인 및 개선사항에 제시하는데 초점이 맞추어져 있다. 본 연구의 주요 연구 내용은 양잠산물 단위당 생산액, 생산 및 소비형태, 가공업체의 원료구매 및 제품 판매구조, 양잠산물 유형별 부가가치 발생 크기, 분야별 애로요인 및 개선사항으로 구성되어 있다.

The present study investigated the feasibility of using the ethanolic extract of Hermetia illucens larvae (HIE) as a whitening improvement material. In cell viability assays using B16F1 melanoma cells, no cytotoxicity was recorded up to 200 ㎍·mL^-1 of HIE. Moreover, while tyrosinase inhibitory activity increased, melanin content decreased in a dose-dependent manner, indicating that HIE likely inhibited tyrosine-induced intracellular melanin biosynthesis in B16F1 melanoma cells. Therefore, HIE is expected to serve as a potent whitening improvement material.

The purpose of this study is to organize research trends by analyzing healing studies using emotional insects, and to suggest future research directions. As a result, only six emotional insect species were used for healing purposes, and most of the age groups of the test subjects were elementary school students and the elderly. As for the type of research, field application of the healing program was dominant at 76.5%. Effectiveness verification was mainly conducted through questionnaires before and after participating in the healing program. In some cases, stress-related salivary hormones were used as indicators or clinical tests were conducted by medical staff. Based on the results of this analysis, future strategies such as finding new emotional insect species, developing various types of healing program models, and expanding and subdividing the target subjects were suggested to promote the growth of the healing industry using emotional insects in the future.

This study aimed to investigate the psychological effect of a healing agricultural program using insect resources and to confirm the persistence of the healing effect. The applied insect was silkworm Bombyx mori (Linnaeus) and 28 adolescents from local children's centers were used as the subjects. The healing agricultural program was applied at the centers for 4 weeks, and stress was measured using salivary α-amylase levels and a survey on life satisfaction, happiness, and insect preference. The results indicated that stress levels decreased, and life satisfaction and insect preference increased after participating in the the healing agricultural program. Furthermore, it was confirmed that this healing effect continued until 4 weeks after the end of the program.

We introduce a method for preserving yellow mealworm (Tenebrio molitor Linnaeus) larvae for an extended period and show that a high percentage of larvae can survive in good health under low-temperature storage conditions combined with specific diapause termination conditions. Our study revealed that we can regulate important development stages such as pupation, emergence, and larval duration by adjusting these termination conditions. When storing larvae aged 6-8 weeks for 140 days, the storage temperature can be varied based on our goals, giving us control over yellow mealworm production to meet specific demands. To produce adult beetles, storing larvae at 15 ℃ with wheat bran and ending diapause at 30 ℃ resulted in 90% pupation rate, with 60% becoming adults in 21 days. If our aim is larvae production, storing them at 10-12 ℃ with wheat bran and ending diapause at 25-30 ℃ allows the larvae to reach a suitable weight for processing. This straightforward approach ensures long-term storage of yellow mealworm larvae and provides a practical way to control their development, allowing efficient mass production tailored to market demands.

5.16 군사정부의 탄생과 함께 적지 적산주의 권농정책에 힘입어 오늘날 크게 발전을 보게된 한국의 양잠업은 사실인즉 이조중엽까지만 하여도 전국 방방곡곡에 크게 번성하였던 민족산업의 하나이었다. 그러나 이조말 서정이 혼탁하면서 강요되기 시작한 가혹한 공납행위와 정상배에 의한 수탈행위의 혹독함에 견디다 못한 생산농민은 뽕나무를 "병민지초"라 부르는 일방, 나무뿌리에 몰래 독즙을 주입하여 자연고사케 함으로써 관으로부터 양잠농을 패업한데 대한 직접적인 질분을 피하면서 가혹한 수탈대상으로부터 가까스로 탈출에 성공할 수 있었다. 그리하여 천혜의 양잠적지가 상전벽해로 되버린 쓰라린 역사를 다시 거슬러 극복하고 1960연대에 이르러 번영의 잠업농으로 재구축하여 놓은 것이다.

우리나라의 잠사업은 농가의 소득증대와 수출산업으로서 계속 성장해 왔다. 그러나 지금까지는 양적인 광대에 치중한 나머지 질적인 면에서 미흡한 점이 있어 국제수준에 비하면 그생산수준이 상당히 낮은 실정에 있다. 그러므로 잠사업이 계속 안정된 산업으로 성장발전해 나가자면 무엇보다 생산량과 직결되는 양잠농가의 기술적인 개량과 경영의 합리화를 꾀하여 생산성의 향상을 기하고 생산비를 절감하여 농가의 실질소득을 증대시키는 동시에 국제시장에 있어서의 경쟁력을 강화해야 할 것이다.(중략)

본 연구에서는 정서곤충을 이용한 치유프로그램 활동이 지역아동센터를 이용하는 아동 43명의 스트레스에 미치는 영향을 조사하였다. 치유프로그램에 이용된 정서곤충은 누에나방[Bombyx mori (Linnaeus)]이다. 스트레스의 정도는 타액 ɑ-아밀라아제 검사를 통해 측정하였다. 스트레스 수치를 평가하기 위한 타액 샘플 채취와 곤충 선호도에 대한 설문지는 곤충치유활동에 참여하기 전과 후에 측정되었고, 활동을 모두 마친 후에는 치유프로그램 참여 경험에 대한 만족도 점수를 평가하였다. 분석 결과, 곤충치유프로그램 활동은 참여 아동의 타액 ɑ-아밀라아제 수치를 통계적으로 낮추고, 곤충에 대한 선호도를 높여준다는 결과를 확인하였다. 누에를 이용한 치유프로그램 활동에 참가한 아동들의 만족도는 5점 만점에 4.23점이었다.

This study investigated the antioxidant effect of Hermetia illucens larvae using different extraction temperatures and solvents. We found significant differences in total phenolic content (TPC), total flavonoid content (TFC), an in three antioxidant indexes 2,2-diphenyl-1-picrylhydrazyl (DPPH), 1,1'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS), and ferric-reducing antioxidant power (FRAP) contents, among the samples depending on the extraction temperature and solvent used. The sample extracted with water at 45℃ (HIW-45℃) showed the highest TPC, DPPH, ABTS, and FRAP contents, while the sample extracted with water at 90℃ (HIW-90℃) showed the highest TFC. These differences can be due to the different chemical structures of the extracted components. Based on these results, HIW-45℃ was the optimal extraction method for Hermetia illucens. We intend to further investigate the availability of functional materials for Hermetia illucens using this method.

As the world population growth and economy develops, the importance of eco-friendly organic waste resource treatment and up-cycling increases. Black soldier fly (BSF) (Hermetia illucens) treats organic waste resources that allows it to be recycled as a feed resource. In this study, we analyzed the nutrients composition, amino acid, and fatty acids of BSF larvae fed three agricultural by-products, namely apple pomace, mandarin waste, and oriental melon waste (mainly generated in South Korea). The highest BSF larvae crude protein and amino acid content was obtained in those fed mandarin waste compared with the other two diets (apple pomace and oriental melon waste). BSF larvae fed apple pomace had the highest crude fat, fatty acid, and lauric acid content compared with the other BSF larvae. Furthermore, all crude protein and fat content of BSF larvae fed the three agricultural by-products exceed that of the original agricultural by-products.
