The purpose of this study is to select various insect species for healing resources and develop a healing program in order to use insect as a healing agriculture. In this study, there are two kinds of breeding kit were developed, one for Gryllus bimaculatus and the other for Oxya chinensis sinuosa. Using these insect breeding kits, we conducted a survey of 60 children and the elderly. In the case of children, the results of the insect breeding satisfaction showed that 30.6% said that the sound of crickets was very good, and 11.1% said that it was good. In addition, the higher the child's awareness of insects, the higher the proportion of children who wanted to raise insects in the future. As a result of a survey of seniors, 45.2% do not like insects and 51.6% are not interested, meaning that most seniors are not very interested in insects. However, the emotions after breeding insects showed positive results, with 45.2% saying their personality became brighter, 48.4% reducing their anger, 48.4% relieving their irritation, 54.8% relieving loneliness, 58.1% feeling more responsible, and 51.6% developing intimacy.

Melanoplus differentialis (Thomas, 1865) is a widely distributed Orthopteran species in North America, including the United States and Mexico. Known for causing damage to various crops such as vegetables and grains throughout its lifecycle. In South Korea, it has been observed concentratedly in the vicinity of the Onsan National Industrial Park in Ulsan and was designated as “Ecosystem Disturbing Species” by Ministy of Environment in 2020. This study aims to present foundational data on pest management strategies for Melanoplus differentialis identified within the Onsan National Industrial Park. Through collaborative efforts between the National Institute of Ecology, related agencies, and tenant private companies from 2020 to 2023, we will demonstrate the reduction in habitat area as a result of proactive pest control measures.

Rhaphidophoridae (Orthoptera: Ensifera), commonly known as cave crickets, are a wingless family and considered the most ancient lineage within Tettigoniidea. However, previous molecular phylogenetic studies and morphological hypotheses have shown inconsistencies. Although their fossils have been found in Baltic amber, their systematic placement remains unrevealed. This study reconstructed a comprehensive phylogeny integrating both extant and fossil lineages. Initially, we revealed relationships within extant lineages through molecular phylogenetics including all extant subfamilies for the first time. Subsequently, using a cladistic approach based on morphology, we confirmed the systematic position of fossil taxa †Protroglophilinae with a report of a new species. Integrating molecular and morphological phylogeney by total evidence tip-dating, we present the comprehensive phylogeny of Rhaphidophoridae considering both extant and fossil groups.

Despite having enabled insects to become the most abundant and successful group on Earth, wings have been lost in numerous insect lineages, including Orthoptera. Melanoplinae, a subfamily that includes over 100 genera and more than 800 species in Acrididae, exhibits various wing-types and dispersal abilities. Some species possess extensive flight capabilities with long wings, while many groups that inhabit alpine environments tend to reduce their wings and dispersal ability. In order to infer the evolutionary history of Melanoplinae and their wings, we conducted molecular phylogenetic research. We established the phylogeny using seven mitochondrial (Cox1, Cox2, CytB, Nad2, Nad5, 12S and 16S) and two nuclear genes (H3 and Wg) for 139 taxa. By investigating the wing types in Melanoplinae, we estimated the ancestral state of the wings and traced their evolutionary history. Our results present that loss and recovery of wings occurred multiple times within Melanoplinae, showing distinct histories across inner taxa within the subfamily.

식용 및 사료용 곤충으로 활용되는 풀무치에 대한 기초 연구로서 발육 단계별 난소 및 알 발육 특성을 조사하였다. 난소발육을 조사한 결과, 풀무치는 1쌍의 난소와 90개 이상의 무영양실형 난소소관을 가지고 있었다. 난소 길이는 5령 약충보다 성충시기가 더 길었다. 성충 1일째 난소길이는 5령 1일보다 약 2.5배 길었다. 난소 길이는 성충 30일까지 증가한 후, 성충 35일부터 감소되었다. 난소소관 길이는 난소 길이의 1/2 정도로, 역시 난소 길이와 같은 경향을 보였다. 난소 및 난소소관 길이는 체중과 비례적인 상관관계가 있었다. 난소소관의 수는 94-104개로 성충 30일이 총 104개로 가장 많았고 35일부터 감소하였다. 성숙란 수 역시 성충 15일부터 확인할 수 있었고, 성충 30일이 50.6개로 가장 많았다. 수정낭의 크기는 또한 발육 단계에 따라 영향을 받았다. 난괴에서 알을 분리하여 산란 후 일별로 발육 특성을 조사한 결과, 산란 4일부터 무게 및 알의 크기가 급격하게 증가하였고, 산란 후 7일부터는 변화의 폭이 거의 없었다. 산란 7일부터 몸체의 구분이 가능했으며, 산란 10일에 부화되었다. 이상의 결과로 볼 때, 풀무치의 난소발육은 성충 30일이 가장 좋았고, 산란 10일경에 풀무치 1령 약충이 우화하는 것으로 판단된다.

본 연구는 최근 산업곤충으로 주목받고 있는 쌍별귀뚜라미의 생산 효율 증대를 위해 수행되었다. 이를 위해 온도, 습도에 따른 부화율 및 부화 기간을 비롯하여 사육 밀도에 따른 생존율 및 산란 온도에 따른 산란수를 조사하였다. 적정 부화 상대습도는 90% 조건에서 부화율 90%를 보여 가장 높았다. 온도별 부화율 조사결과 20℃에서 98.3%로 가장 높았다. 또한, 온도별 부화 35℃조건에서 7.1일로 가장 짧게 나타났다. 또한 사육 용기에 3,000~20,000개체를 투입하여 35일간 조사한 밀도별 생존율은 34~18%였다. 쌍별귀뚜라미의 먹이에 채소 급여가 성장에 미치는 특성을 조사한 결과 생존율은 1.8배, 생체중량은 2.5배 높게 나타났다. 온도별 산란수 조사결과 25℃ 조건에서 30일 후 1,710개로 가장 높았다.
