국립수목원 산림생물다양성연구과는 2023년부터 산림생태계 보전을 위한 화분매개곤충 특성연구 사업을 추진하면서 그 첫 번째 단계로 화분매개곤충 인벤토리 구축을 위한 연구를 수행하고 있다. 수목원 4개소(강원도 립화목원, 경상남도수목원, 국립수목원, 대구수목원)에서 9종의 식물(국수나무, 미선나무, 산수유, 산철쭉, 생강 나무, 수수꽃다리, 아까시나무, 진달래, 히어리)을 대상으로 각 식물에 어떤 곤충들이 방문하는지 쓸어잡기 방법 을 이용하여 확인하였다. 조사된 곤충 중에서 가장 많은 개체수를 차지하고 있는 곤충은 파리목(1,407개체)이었 으며, 26과의 다양한 파리목 곤충들을 확인할 수 있었다. 그중에서도 가장 많은 개체수를 차지하고 있는 과는 재니등에과 (4속, 5종, 651개체), 꽃등에과 (24속, 34종, 302개체), 기생파리과 (8속, 9종, 111개체)로 집계되었으며 이 중에서도 꽃등에과의 종다양성이 가장 높게 나타났다. 조사한 식물 중에서 가장 많은 파리목 곤충이 모인 식물은 수수꽃다리와 미선나무였고, 각각 314, 308개체 이상의 파리목 곤충을 확인하였다. 반면 파리목 곤충의 방문이 가장 저조한 식물은 국수나무와 아까시나무였으며 확인된 개체수는 각각 38, 45개체였다. 우리는 화분매 개곤충에 대한 인벤토리 구축을 통해 화분매개곤충에 대한 다양한 분류학 및 생태학적 데이터의 지속적인 확보 를 위해 노력하고 있으며, 본 소모임에서 이에 대한 발전방안 및 축적된 데이터의 활용방안에 대해 모색하고자 한다.

본 연구에서는 한국산 미기록속인 이마줄불청객파리속(신칭)과 미기록종인 작은눈이마줄불청객파리(신칭)를 처음으로 보고한다. 우리는 이 종이 포식성 거미의 섭식과정에 관여하는 phoretic relationship의 습성을 갖는 것을 확인하였다. 이 종의 성충에 대한 기재문과 사진 및 DNA바 코드 서열을 제공한다.

Curtonotidae, known as the quasimodo flies, in Diptera currently includes about 100 described species in five genera (Axinota Wulp, 1886; Curtonotum Macquart, 1844; Cyrtona Séguy, 1938; Depressonotum Grimaldi & Kirk-Spriggs, 2012; Tigrisomyia Kirk-Spriggs, 2010) worldwide. Curtonotid species have great potential as case studies for biological diversity, evolution, and zoogeography based on wide distribution and sufficient diversity. In the present study, Curtonotum maritimum Ozerov, 2007 is newly added to Korean insect fauna. This is also the first record of Curtonotidae from the country. We here provide morphological diagnosis and images including genitalic structures for accurate identification.

Milichiidae Schiner, 1862 is a small family of Diptera, with 19 genera and 360 described species worldwide. In Korea, only two species in a single genus, Aldrichiomyza Hendel, 1914, have been recorded. Milichiid species, small-sized acalyptrate flies, are generally associated with decaying plants and animals. In particular, Desmometopa Loew, 1866 in the family has a commensalistic habit, more precisely the phoretic relationship, that has been observed with predacious insects and spiders, in which adults feed on the juices of the prey. In this study, we recognized Desmometopa microps Lamb, 1914 for the first time in the Korean Peninsula. This is also the first record of the genus from the country. Herein, we provide diagnosis of D. microps based on the Korean specimens with images.

Vespula rufa (Linnaeus, 1758), known as the red wasp, is a social wasp species. We analyzed the complete mitochondrial genome of V. rufa from South Korea, for an ongoing systematic study of the Korean Vespidae. This species is distributed in northern parts of North America, northern and central Europe, and parts of Asia. It can be distinguished from other species of the genus by usually having reddish brown areas on the 1st and 2nd tergites. The mitogenome is 17,663 bp in length, includes 13 protein-coding genes, 24 transfer RNA genes, and two ribosomal RNA genes. The nucleotide composition is 40.5% adenines, 43.00% thymines, 6.1% guanines, and 10.4 % cytosines.

A study to apply phase change material(PCM) to rapid hardening cement paste forming semi-rigid pavement was carried out. The characteristics fresh and hardened paste were evaluated through the experiment for a total of 6 mixtures according to the cement type and the substitution of phase change material for acrylate. The fluidity by substituting phase change material for acrylate satisfied the target flow time of 10 to 13 seconds. In case of setting time, it was possible to secure the performance of rapid hardening cement by substituting phase change material, and if the substitution ratio over 60%, the initial set occurred 1 to 2 minutes faster than other mixtures. In case of compressive strength and bond strength, it showed similar strength characteristics with the plain mixture, and it satisfied both the target compressive and bonding strength of 36MPa and 2MPa. The mixture substituting phase change material showed higher resistance to chloride ion penetration than the mixture only using acrylate and the OPC level was insufficient. From the results of physical and mechanical performances of semi-rigid pavement cement paste, the phase change material substitution rate of 20% was effective in the range of this study.
