  • 털게, Erimacrus isenbeckii는 갑각류(Crustaces, Decapods)중에서 대형 단미류(Brachyura)로서 우리나라 영일만, 동해북부, 사할린, 오호츠크해, 알라스카연안에 분포하는 유용종으로 우리나라에서는 중요한 어업대상종으로 자원관리가 필요하다. 최근에는 활어로서의 수요량이 급증하는 반면 자원량이 감소되어 공급량을 충당하기 어려운 실정이므로, 인공종묘생산에 의한 대량생산을 하기위해 부화후 유생의 먹이생물을 파악하여 대량생산시 양식기술을 확립하기 위한 자료를 마련하고자 조사하였다. (중략)

  • Present study was to investigate the effect of dietary vegetable sources such as carrot, peahull and squash on mineral balance of Na, K, Ca, Fe, Cu, Zn and Mg in mice. It would also determine if the kind, level and feeding period of vegetables can affect the mineral balance. One hundred and thirty mice weighing $29{\sim}30g$(8 weeks of age) were randomly selected. Ten mice were fed their standard diet, and the others were divided into three experimental groups that were fed standard diet supplemented with carrot, peahull and squash. Mineral intake and urinary and fecal excretion of minerals were measured to investigate the effect of the kind, level and feeding period of vegetables on absorption rate and balance of minerals. Body-weight gain was increased in high peahull diet group compared to the control. No significant difference was observed for feed efficiency ratios between different experimental groups and urine volume was increased by vegetable fed group. Na, Ca, Fe, and Cu intake were lower in high squash-diet fed soup. K intake was higher in carrot fed mice, and Zn, and Mg intake were higher in peahull fed mice. Absorption rate and balance of mineral in control group resulted in positive balance while experimental groups showed negative. The kind of vegetable, feeding level and feeding period affected the intake of Na, K, Ca, Cu and absorption rate of Cu, Zn and balance of K, Cu, Zn to negative. In spite of the higher intake of t Zn and Mg, in experimental groups the absorption rate showed negative balance.

  • Insects and their extract have been traditionally used as medicinal resources in Asia. Recently, Gryllus bimaculatus and the larva of Tenebrio molitor, Protaetia brevitarsis, and Allomyrina dichotoma were enlisted as general food ingredients by Korean Ministry of Food and Drug Safety. As the interest in these insects is growing, the detailed investigation is needed for the standardization of suitable and safe rearing techniques. This survey was conducted via personal interviews about edible insect rearing farms in Korea. The basic feed is fermented oak sawdust for P. brevitarsis and A. dichotoma and wheat bran for T. molitor. The various feed additives are blended with each farm's own recipes. The overall growth condition, including sawdust fermentation method, feeding period, and rearing density, varies among the investigated farms. It seems that weight of last instar larva was correlated with the rearing density and duration of the larval period. The heavy metal contents were analyzed after 48 hour starvation and they were very small amount or not detected in investigated insects. We believe that the present data will contribute to develop and standardize the safe rearing techniques of edible insects in Korea.

  • 본 연구의 목적은 흰점박이꽃무지 사육농가 및 사육환경에 대해 일반농가의 실태를 조사·분석하여 식용곤충 사육시설에 대한 기초 연구자료를 수집하기 위한 것이다. 전국에 곤충사육 농가로 등록한 업체 중에서 흰점박이꽃무지를 사육하는 농가 17농가를 대상으로 설문조사를 실시하여 농장운영 및 시설·장치 현황 등을 조사하였으며, 주요 결과는 다음과 같다. 일반적으로 곤충사육 농가는 대부분 농가형으로 운영되고 있지만, 생산업, 유통업 및 가공업 등으로 신고하여 곤충사육 농가에서 직접 생산, 가공 및 제품 개발 등을 하고 있는 것으로 나타났다. 그리고 대부분의 곤충사육 농가는 판넬 형식의 건축물 내에서 냉·난방기를 가동하여 곤충의 생육환경을 조성하고 있으며, 필요에 따라 IoT 기반의 사양관리 장치 및 운영관리 시스템을 활용하고 있는 것으로 파악되었는데, 식용곤충 대량생산을 위한 사양관리 장치 및 생산 기반시설 구축은 여전히 부족한 상황으로 개선이 필요해 보인다.

  • 우리나라의 계육생산은 1965년 이전까지 채란용, 노계가 주된 공급원이었으나 1962년 이후 우육 및 돈육생산이 감소되고 미국 잉여농산물의 순조로운 도입에 의한 사료의 안정적 공급 및 우수한 외국계의 도입과, 이와 병행하여 국민소득수준이 향상됨에 따라 단기대량사육이 가능한 육계생산이 1965년을 기점으로 급속히 성장하게 되었다. (중략)

  • This research was conducted to develop seedling production techniques in flat oyster, Ostrea dense lamellosa. The cultivation of larvae, artificial spat and spats collection in natural conditions rate were examined. In the mass culture tank (3 tons), average growth rates of the D Shape larvae of initial shell length (153.4 ㎛) and shell height (153.4 ㎛) were 202.6% and 212.9% at 16 days and 227.1%, 241.8% at 20 days, respectively. Instantaneous death and survival rate of the larvae were 0.160 and 54.8% at 16 days and 0.057 and 43.2% at 20 days, respectively. Collection rate of flat oyster from bottom using various collectors with oyster shell, scallop shell, ark shell and PVC plates were 32.9%, 24.1%, 16.8% and 10.0%, respectively. and the greatest collecting rate was 131.9 individuals/shell (32.9%) in laid collectors on the bottom. The collecting rate of the oyster larvae were better in laid collectors on the bottom 83.8 individuals/collection than in the suspended string 54.2 individuals/collection. in all collecting substrates. Early spats settled on collectors were grew to 2.38 $\pm$ 0.97 ㎜ in shell length and 2.16 $\pm$ 0.86 ㎜ In shell height at 26 days. The spats were grew to 28.58 $\pm$ 2.39 ㎜ in shell length and 31.65 $\pm$ 2.03 ㎜ in shell height during the 4 month mid-term cultivation. In the period of cultivation, the mean number of spats attached to collectors were 10.3 individuals at oyster shells, 5.8 scallop shells, 4.0 ark shells and 1.5 PVC plates, respectively.

  • Korean rhinoceros beetles (Allomyrina dichotoma), which can be found in broad-leaved forests in mountainous habitats and lives for around one year in wild. This beetle is currently popular as a pet and traditionally regarded as a medicine for liver-related diseases in Korea. It is reported that the economic losses in the mass-rearing facilities by virus infection have been increased since the 2010s in Korea. The causing virus for the A. dichotoma was firstly reported as an Oryctes rhinoceros nudivirus (OrNV) in 2015. We, here, observes that serious morphological changes in the intestinal tube from the OrNV-infected beetles, and report five genes, which are regulated by OrNV infection in the intestine; Krueppel-like factor 15 (Klf15), Endoplasmic reticulum aminopeptidase 2 (ERAP2), U5 small nuclear ribonucleoprotein 200 kDa helicase (Snrnp200), Muscleblind-like protein 2a (mbnl2a), and MIMI_L93. The results may provide a clue to the early diagnosis and disease treatment during the mass-rearing facilities of the A. dichotoma.

  • 1. 침파리의 동계사육 결과 평균온도 $23.7^{\circ}C$에서 유충기간 7일, 용기간 9.2일, 전산란기간 14.2일, 성충수명 23.3일이었다. 2. 5월부터 7월까지 사육온도 $25\pm1^{\circ}C$로 고정시켰을 때의 생육기간은 유충기간 8.0일, 용기간 5.3일, 전산란기간 11.7일, 성충수명 30.1일 이었다. 3. 용 개체중량은 5월-7월의 $25\pm1^{\circ}C$에서 13.3mg으로서 현저한 증가를 볼 수 있었다. 4. 전산란 기간중의 성충사망율은 습도 조절(R. H.)에 따라서 큰 차이를 보여주었으며 누대사육을위해서는 $55-65\%$의 R.H.를 유지할 필요가 있을 것으로 본다. 5. 성충의 산란율은 산란 시작후 제8-10일에 제일 높다.

  • Orius strigicollis Poppies is an indigenous natural enemy of thrips pests in Korea To develop an efficient mass rearing system for Ο. strigicollis, effects of hatchability, egg numbers and egg harvesting time of Ο. strigicollis were measured in cylindrical cage (251 ㎤) under the conditions of photoperiod 16L : 8D, $55\pm$10% RH and $25\pm$$2^{\circ}C$. The hatchability and developmental period of eggs were 88.5% and 5.7 days, respectively. The highest emergence rate (50.8%) was achieved when the number of eggs laid was ranged from 50 to 100 per arena. The proper harvesting time of newly produced adults was 17 days postoviposition. Relationship between the number of resulting adults per female and the number of female adults per arena was Y : -10.7971n (X) +44.659 ($R^2$=0.7619). The generation time (T), the net reproductive rate ($R_{0}$ ) and the intrinsic rate of natural increase ($r_{m}$ ) were 26.5 days, 6.18 and 0.0687, respectively.
