한국에서 시설 딸기 해충을 방제하는 대표적인 방법은 살충제를 사용한 화학적 방법이다. 이는 농가에서 쉽게 접하고 처리 시기를 마음대로 조절할 수 있는 장점이 있지만, 방제 비용과 농업인부의 빈번한 화학살충제 노출이 큰 단점이다. 경주시 상평농원은 천적을 적극적으로 사용하는 농가로써 2020년부터 현재까지 4년간 4종의 천적 을 구매, 사육, 방사를 실시하였다. 방사한 천적은 점박이응애 방제용 칠레이리응애와 사막이리응애, 작은뿌리 파리 방제용 뿌리이리응애, 진딧물 방제용 콜레마니진딧벌이며, 농장의 규모는 재배동 1,250평, 육묘동 450평으 로 자가육묘를 하기에 1년 내내 딸기를 재배하는 농장이다. 본격적으로 천적을 활용하는 시기는 9월부터 이듬해 5월까지 약 9개월이다. 이 기간 동안 소요된 비용은 천적을 구매하고 자가사육하여 사용한 경우(154만원), 천적과 약제를 구매하여 같이 사용한 경우(240만원), 천적만 구매하여 사용한 경우(262만원), 약제만 처리(377만원) 순 으로 나타났다. 다만, 이 결과는 과학적으로 반복 및 재현 검증되지는 않았고, 각 농가의 천적과 해충의 생태에 대한 이해도와 작물 재배능력, 천적 사육능력에 따라 차이가 있을 수 있다.

The Red-spotted Apollo Butterfly (Parnassius bremeri ) is member of Snow Apollo Butterfly in Genus Parnassius which has been designated as the most endangered insect around the world and recorded in IUCN Red List of Threatened Animals and Appendix II in CITES. The lack of distributional information of Parnassius bremeri is one of the main problems when trying to assess the threats to and planning conservation strategies for this endangered species. The pheromone method made it easier to detect local populations of the species, not to disturb the habitat and can be used by providing a useful tool for conservation research. Sampling by breeding captivity in Holoce Ecosystem Conservation Research Institution (HECRI) was used. Each of 3 individuals male, mated and unmated female, end of the abdomen tissue and abdominal tissue containing the sphragis were cut. The pheromone was extracted as method presented by Hernández-Roldán et al. (2014). Among pheromone fatty alcohol to the (Z, Z, Z) -9,12,15-octadecatrien-1-ol and Eicosane classified as hydrocarbon of unmated female was detected higher rate than mated female. Two pheromone can be helpful to attract males in potential population.

For the 2 years of farming, at the indoor circulating aquaculture system, four kinds of skeletal deformities were found among 60 Far Eastern catfish, Silurus asotus. Deformities saw jawbone’s luxation, abnormality of upper lip and malocclusion. Spinal deformity was most fatal deformities with low weight and small length. Jawbone’s luxation had 1 maxilla and 2 mandibles. Abnormality of upper lip had just lip was back over. Malocclusion’s left maxilla and right maxilla were not balanced. This experiment was any deformities in this species through the deformity can grasp how it affects.

Fermented soybean food is one of most economical and health food due to its valuable nutritional and medicinal attributes and have been consumed for centuries as flavoring ingredient in Korea. On fermented soybean food such as doenjang, aroma compounds are important property because they determine taste and grade of fermentation. This study investigated variety of aroma compounds of doenjang made from different soybean genotypes. Aroma compounds in twelve different doenjang made from two cultivar (Daewon and Taekwang) and ten elite lines were extracted by steam distillation extraction (SDE) method and analyzed by gas chromatography/mass spectrometry (GC/MS). Aroma compound were detected over 80 kinds in eight samples (Daewon, Taekwang, MY177, MY187, MY189, MY192, MY204 and MY205) and under 70 kinds in four samples (yeonchun1, MY188, MY203 and MY206). Among the detected aroma components, 47 compounds were assigned as aromatic compounds (21), long chain fatty acid (13), short chain fatty acid (5) and others (8) by the computer library (Wiley 7n program). The major aroma compounds in twelve different doenjang were benzaldehyde, benzeneacetaldehyde, 2-methoxy-4-vinylphenol, pyrazine type compounds, cysteaminesulfonic acid, palmitic acid, oleic acid and linoleic acid. Each doenjang made by same condition (microbe, temperature, aging time and etc) had a difference in ratio and variety of aroma compounds due to different components having soybean genotype.
