Chinese longhorned beetle (CLB; Anoplophora chinensis) and Asian longhorned beetle (ALB; A. glabripennis) were accidentally introduced into the US from the Asia back in 90s’ and have been causing economic damage on hardwood species in the US. An international cooperative team made field surveys in Korea to find parasitoids of CLB and ALB using sentinel logs that were infested with eggs of the two cerambycids.. As a result, two parasitic wasps of Anopolophora species were newly recognised from Korea: Aprostocetus anoplophorae Delvare (Eulophidae) as an egg parasitoid of CLB and Leluthia honshuensis Belokobylskij & Maeto (Braconidae) as a larval parasitoid of ALB. Identification was made using both morphological and molecular data. Morphological information was provided along with images of developmental stages and adults.

The genus Sphathius is belong to the subfamily Doryctinae in the family Braconidae and are described with >300 species in the world (Shenefelt and Marsh, 1976). This genus is distinguished from other winged Doryctinae by 1) forewings with three submarginal cells; 2) first subdiscal cell of forewing closed; and 3) first metasomal segment petiolate, widening apically, lacking basal wing-like projections, and inserted on propodeum near coxal bases (Marsh, 1997). For the purpose of finding the biological agent for Asian longhorned beetle (ALB; Anoplophora glabripennis (Motschulsky)) and Citrus longhorned beetle (CLB; A. chinensis (Förster)), we had installed the ALB- and CLB-infested sentinel logs to attract parasitoids at experimental field of the Korea National Arboretum during summer season in 2014. Several L1 and L2 CLB larvae were found attacked by braconid larvae that were reared to adult stage. Their larvae are identified to Spathius gwangneungensis sp. nov. belong to the Spathius exarator species group. This new species has special characteristics as following; Body reddish brown or dark reddish brown, body length 2.5~3.7mm and forewing length 2.2~3.0mm in female and body length 2.1~2.6mm and forewing length 1.5~2.0mm in male, hind femur distinctly transversely aciculate dorsally, forewing more or less infuscate with a longitudinal hyaline band medially, vein m-cu of hind wing interstitial, second tergite entirely sculptured without striation, and third to fifth tergites basally sculptured. Ovipositor sheath 0.6 times as long as metasoma.

이 논문에서는 최근 다시 주목을 끌고 있는 압전소자를 이용한 에너지 획득에 대한 개념을 한 진동원에 응용하여 그 에너지의 이용가능성을 분석해 보고자 한다. 에너지 획득기로는 가장 일반적으로 사용되고 있는 유니모프 압전 캔틸레버 벤더를 사용한다. 먼저 압전 에너지 획득기에 대해 base excitation에서의 거동을 이론적으로 분석하고 실험실내에서 수행할 수 있는 압전 에너지 획득기를 제작하여 가진기 상에서 발생하는 전력을 측정한다. 시뮬레이션과 실험결과를 통해 진동에너지로부터 획득한 전기에너지가 각종 센서는 물론 기계부품들의 진단시스템에 필요한 전원을 공급할 수 있음을 알 수 있다.

유리알락하늘소(ALB; Anoplophora glabripennis) 및 알락하늘소(CLB; A. chinensis)는 동북아시아로부터 북미 및 유럽으로 침입한 해충으로 북미지역에서 도심 가로수 및 산림에 심각한 위협을 주고 있다. 이들 알락하늘소류에 대한 전문적인 기생천적을 탐색하기 위해 2014년부터 2015년 현재까지 전남 고흥, 순천, 경남 김해, 울산, 경기 포천, 강원 인제에서 산란 받은 Sentinel log를 이용하여 알 및 유충에 기생하는 천적을 조사하였다. 그 결과, 2014년 경기 포천에서 CLB 1령 유충의 외부기생벌인 고치벌 일종Spathius sp., 2015년 전남 순천에서 CLB 1령 유충의 외부기생벌인 개미침벌(Sclerodermus harmandi), 울산에서 ALB 알의 내부기생벌인 좀벌 일종Aprostocetus sp.가 확인되었다. 이 중 개미침벌은 이미 중국에서 대량방사하여 이용되고 있으나 기주특이성이 없어 알락하늘소류의 전문적인 기생천적으로써 효과가 없을 것으로 판단되며, 앞으로 본 조사에서 채집된 고치벌 일종인 Spathius sp.와 좀벌 일종인 Aprostocetus sp.에 대하여 알락하늘소류의 전문적인 기생천적 여부를 확인할 계획이다.

Spathius exarator의 종 그룹에 속하는 S. ibarakius Belokobylskij et Maeto가 한반도에서 알락하늘소(Anoplophora chinensis)의 1령과 2령 유충에 외부기생하는 것으로 확인되었다. 산란유인목을 이용하여 유리알락하늘소와 알락하늘소의 기생봉을 탐색하는 과정에서 이 고치벌이 발견되었다. 이 고치벌의 진단형질과 수컷의 특징, 삽화 및 한반도에 분포하는 종들의 기주목록을 함께 제공하였다. Spathius ibarakius Belokobylskij et Maeto, which belongs to the Spathius exarator species group (Hymenoptera: Braconidae: Doryctinae) was found as an ectoparasitoid of the first- and second-instar larvae of the citrus longhorned beetle, Anoplophora chinensis ($F{\ddot{o}}rster$) from Gwangneung, Pocheon, Korea. The discovery of this braconid wasp was made during the survey for parasitoids of the Asian and citrus longhorned beetles by using the sentinel log method. We herein describe diagnostic characters of S. ibarakius, including those of the male, and also provide illustrations. In addition, we present a host list of Korean species belong to genus Spathius.
BIOLOGICALLY-BASED DOSE-RESPONSE MODEL FOR NEUROTOXICITY RISK ASSESSMENT
Slikker, William Jr.,Gaylor, David W. Korean Society of ToxicologyKorea Environmental Mu 1990 Toxicological Research Vol.6 No.2
The regulation of neurotoxicants has usually been based upon setting reference doses by dividing a no observed adverse effect level (NOAEL) by uncertainty factors that theoretically account for interspecies and intraspecies extraploation of experimental results in animals to humans. Recently, we have proposed a four-step alternative procedure which provides quantitative estimates of risk as a function of dose. The first step is to establish a mathematical relationship between a biological effect or biomarker and the dose of chemical administered. The second step is to determine the distribution (variability) of individual measurements of biological effects or their biomarkers about the dose response curve. The third step is to define an adverse or abnormal level of a biological effect or biomarker in an untreated population. The fourth and final step is to combine the information from the first three steps to estimate the risk (proportion of individuals exceeding on adverse or abnormal level of a biological effect or biomarker) as a function of dose. The primary purpose of this report is to enhance the certainty of the first step of this procedure by improving our understanding of the relationship between a biomarker and dose of administered chemical. Several factors which need to be considered include: 1) the pharmacokinetics of the parent chemical, 2) the target tissue concentrations of the parent chemical or its bioactivated proximate toxicant, 3) the uptake kinetics of the parent chemical or metabolite into the target cell(s) and/or membrane interactions, and 4) the interaction of the chemical or metabolite with presumed receptor site(s). Because these theoretical factors each contain a saturable step due to definitive amounts of required enzyme, reuptake or receptor site(s), a nonlinear, saturable dose-response curve would be predicted. In order to exemplify this process, effects of the neurotoxicant, methlenedioxymethamphetamine (MDMA), were reviewed and analyzed. Our results and those of others indicate that: 1) peak concentrations of MDMA and metabolites are ochieved in rat brain by 30 min and are negligible by 24 hr, 2) a metabolite of MDMA is probably responsible for its neurotoxic effects, and 3) pretreatment with monoamine uptake blockers prevents MDMA neurotoxicity. When data generated from rats administerde MDMA were plotted as bilolgical effect (decreases in hippocampal serotonin concentrations) versus dose, a saturation curve best described the observed relationship. These results support the hypothesis that at least one saturable step is involved in MDMA neurotoxicity. We conclude that the mathematical relationship between biological effect and dose of MDMA, the first step of our quantitative neurotoxicity risk assessment procedure, should reflect this biological model information generated from the whole of the dose-response curve.

Leluthia honshuensis Belokobylskij & Maeto, 2006 (Hymenoptera: Braconidae) was found as an ectoparasitoid of the first- and second-instar larvae of the Asian longhorned beetle (ALB), Anoplophora grabripennis (Motschulsky) (Coleoptera: Cerambycidae) from Gwangneung forest, Pocheon, Republic of Korea. This discovery was made during the investigation for parasitoids of ALB in 2016. We report here the first known host of Leluthia as the ALB. In addition, a diagnosis and detailed photographs of L. honshuensis are given. Images of the holotype specimen are also provided for comparison.
