Gonggeom-ji is designated wetland protected area by the Ministry of Environment of Korea in 2011 because of it’s high biodiversity and historic value. It contains a reservoir, paddy and forest site which has diverse niches for insects. Three transect lines of 50m were designated. Data were collected in May, October, November in 2017 represented as seasons for spring, summer and autumn respectively. Quantitative methods were conducted along each transect line by sweeping and pitfall trap. Based on this study total of 1079 individuals of insect fauna were collected, representing 170 species in 60 families and 8 orders. The highest diversity, richness and evenness index were observed in the forest site in May(4.77, 8.6 and 0.91 respectively) and the highest dominance index was observed in the forest site in November(0.64). The highest similarity index was observed in the reservoir site in May and August(0.519).

The mandible character of the Lucanidae is vary by considering of developmental difference in male individual specimen. Especially, species of Genus Cyclommatus Parry, 1862 presents strong mandibular allometry. In this research, The species group which related to Cyclommatus montanellus Möllenkamp, 1904 has been evaluated for the first time in this research with inner teeth composition and positioning to establish clear taxonomic key to each species.

우리나라는 1996년 WTO/SPS(동식물검역협정)에 따라 검역병해충제도를 정비하였으며, 해외병해충의 위험으로부 터 자국내 생물자원과 자연환경을 보호하기 위하여 다양한 노력을 하고 있다. 현재까지의 수입식물 검역과정에서 검출된 병해충을 분석한 결과 병해충 검출건수는 수입량이 늘어나면서 증가하는 추세이다(00년 6,233건 → 17년 12,749건). 하지만 식물의 수입 유형에 따라 곡류, 사료류 등 비재식용 식물의 경우 병해충 검출률은 07년 이후 감소하고 있으며(07년 9.8% → 17년 3.3%), 묘목류, 종자류 등 재식용 식물의 경우 11년 이후로 지속적으로 증가하고 있어(11년 7.9% → 17년 22.0%) 재식용 식물을 통한 해외 병해충의 유입 위험도가 가증되고 있는 상황이다. 따라서 우리는 검역본부에서 운영하고 있는 자체 전산시스템인 병해충정보시스템(PIS)을 이용하여 2000년 이후 식물검역과 정에서 발견된 병해충 검출동향과 수입 유형에 따른 검출동향을 비교분석하고, 2016년 대비 2017년 병해충 검출동향을 파악하였다.

Cryopreservation of avian semen is a useful tool to preserve genetic resource for aim of preventing extinction induced by infectious disease like avian influenza. Unlike those of mammals, data from chicken cryopreserved semen has not been showed feasible results. So, various cryoprotectants and diluents have been examined in many methods. In this report, as a major ingredient of avian seminal plasm, glutamine was substituted by alanyl glutamine to enhance physiological stability of chicken semen during freezing. We studied effect of glycerol and Dimethylacetamide(DMA) on motility and progressive motility of spermatozoa using glutamine diluent(EK-G) or alanyl glutamine diluent(EK-A) condition. The semen of Ogye was collected twice a week by the dorso-abdominimal massage method and diluted with same volume of EK-G or EK-A at 25℃ and stored for 10 min at 4℃ in cold chamber. Glycerol or DMA was added to diluted semen to reached 7% of final concentration at 4℃. After 3min of equilibration, the diluted semen was packed into 0.25ml straws and subjected to cryopreservation used freezing equipment. The packed straw were placed on height 5 cm above surface of liquid nitrogen(LN2) and held for 10min. After preserved for 2 weeks, the straw was thawed onto the 4℃ cooling bath. The images of motility and progressive motility spermatozoa were recorded by digital image recorder and analyzed by manual. The results showed 68.5% motility and 34.1% progressive motility in DMA/EKA diluent, 31.45% and 17.6% in glycerol/EKA, 45.4% and 8.6% in DMA/EKG, and 9.7% and 6.4% in glycerol/EKG. With these results, the alanyl glutamine and DMA could be used as a main composition of diluent and cryoprotectant for cryopreservation of chicken semen.

The techniques of IVM, IVF and IVC of canine oocytes may provide useful information for gamete salvage programs and the conservation of endangered canidae. This investigation has been made to determine the efficiency of in vitro maturation (IVM) as a basic experiment to study the development of canine oocytes after in vitro fertilization (IVF). The rate of oocytes developing to the MII stage was higher in the hormone treated group (10 IU/ml hCG+eCG, 14.7%, p<0.05) than in the control group (0 IU/ml hCG+eCG, 10.0%). The monospermy and pronuclear rates of canine oocytes were investigated after caffeine treatment on IVF. Canine oocytes were fertilized in the Fert‐TALP medium supplemented with 0, 10, 20 or 30 mM caffeine (Fert I, Fert II, Fert III or Fert IV, respectively). The highest pronuclear formation rate was obtained in the Fert I for 24 h IVF (6.7%, 6/89). Therefore, it is believed that unlike in other mammals, caffeine in canine IVF does not increase the efficiency of fertilization rate, and is not an important factor.
