We introduce a method for preserving yellow mealwom (Tenebrio molitor) 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. When storing larvae 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 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.

To assess the accuracy of species delimitation in the genus Aphaenomurus Yosii, we conducted a comparative micro-morphological study and molecular analysis using two mitochondrial (COI, 16S) and two nuclear genes (18S, 28S) on 118 specimens from 24 localities. The results showed that the morphological characters of A. vicinus and A. interpositus, as presented in the original description, were intermixed in phylogenetic lineages within the genus and did not form independent lineages. Furthermore, there were enough differences among Aphaenomurus individuals to be considered as morphologically distinct species (Th. III is 1+1 or 2+2, Abd. I is 2+2 or 3+3, Abd. II is 2+2 or 3+3), but they do not form an independent lineage. Molecular and morphological analyses have determined that A. vicinus and A. interpositus are the same species, exhibiting morphological variation in dental spines formula, claws, chaetotaxy, and other features. Additionally, the genus Aphaenomurus forms a monophyletic clade, which is further divided into several lineages within the genus. No morphological differences were observed to distinguish these lineages. This cladistic divergence is attributed to heteroplasmy, which is supported by previous studies that have suggested the possibility and problems of heteroplasmy in Collembola, and by the high genetic distances between individuals in the mitochondrial genes of Aphaenomurus.

The insect industry in Korea is currently undergoing steady expansion. Among the various insects kept as pets or for educational purposes, four mantis species, including Hierodula patellifera (Audinet-Serville), Tenodera sinensis Saussure, Tenodera angustipennis Saussure, and Statilia maculata (Thunberg), are becoming increasingly popular, leading to higher demand. As we aimed to raise mantises, we collected oothecae, some of which were found to be parasitized by dermestid beetles. These parasitoids have been unequivocally identified as Thaumaglossa rufocapillata Redtenbacher based on morphological characters. A diagnosis, habitus photographs, and illustrations of diagnostic characters are provided to facilitate identification. We also present the complete mitochondrial genome sequence of T. rufocapillata for providing fundamental data for research aimed at controlling pests in the insect industry.

｢곤충산업의 육성 및 지원에 관한 법률｣ 제6조에 따라 국립농업과학원에서는 2020년도에 곤충산업 종사자를 대상으로 실태조사를 실시하 였다. 곤충산업 종사자의 유형은 생산업이 가장 많았고(98.5%), 남성 비율이 높았으며(80.4%), 연령은 50대가 36.4%로 가장 많았다. 산업곤충 의 생산 유형은 식약용 곤충 66.5%, 사료용 12.8%, 애완용 20.7%였으며, 식약용 곤충 중 흰점박이꽃무지는 69.6%로 가장 많이 생산되고 있었 으며, 사료용으로는 귀뚜라미류가 31.2%, 애완(정서)용으로는 장수풍뎅이가 45.6%로 가장 많이 생산되고 있었다. 제품의 형태는 분말이 68.5% 로 가장 높았고, 생물로 판매되는 경우는 40.9%로 조사되었다. 연간 소득이 있는 곤충농가는 77.3%이고, 그 중에서 연간 판매금액이 2천만원 미 만인 경우가 65.4%를 차지하였다. 곤충산업 종사자들의 가장 큰 애로사항은 판로 확보로 조사되었다(84.0%). 이와 같이 곤충산업 종사자는 매 년 늘어나고 있지만 20대~40대 청년 곤충농가 대표는 줄어들고 있고, 생산은 특정 대표 곤충 종에 한정되어 있으며, 매우 영세하게 농가가 유지 되고 있음을 알 수 있다. 또한 곤충 농가에서는 판로확보에 가장 큰 어려움을 느끼고 있어 산업곤충 소비 촉진을 위한 이용 기술 개발이 시급하다 고 판단된다.
