톱다리개미허리노린재(Riptortus pedestris Fabricius)는 지역에 따라 사과에 심각한 경제적 피해를 야기하고 있지만, 사과에서 톱다리개미 허리노린재 친환경 방제에 대한 연구는 전무한 실정이다. 따라서, 이번 연구에서는 톱다리개미허리노린재의 집합페로몬 성분 중 (E)-2-hexenyl (Z)-3hexenoate (E2HZ3H)이 노린재검정알벌(Gryon japonicum Ashmead)과 노린재깡충좀벌(Ooencyrtus nezarae Ishii)에 미치는 영향을 조사하였다. 사과 과수원에서 E2HZ3H는 전체 과수원에 발생하는 2종의 포식기생자의 밀도에는 직접적으로 영향을 주지 않았고 이들 포식기생자의 공간분포도 변화시키지 않았다. 그러나, E2HZ3H 루어가 설치된 지역 주변에서는 2종의 포식기생자 모두 제한적으로 유인하는 것을 확인하였다. 따라서, E2HZ3H 루어는 사과 과수원 내에서 정밀방제를 목적으로 친환경 방제에 고려될 수 있을 것으로 생각된다.

Ooencyrtus nezarae lshii (Hymenoptera: Encyrtidae) is a major egg parasitoid of Riptortus pedestris (F.) (Hemiptera: Alydidae). One of the components of the aggregation pheromone of R. pedestris, (E)-2-hexenyl (Z)-3-hexenoate (E2HZ3H), is known to attract O. nezarae female. Response of O. nezarae females to E2HZ3H and its isomers was studied using electro-antennogram (EAG) and field tests. O. nezarae females showed higher antennal response to E2HZ3H and Z2HE3H isomers than E2HE3H and Z2HZ3H. In field tests, O. nezarae females were attracted to E2HZ3H traps, but not to Z2E3 traps. Interestingly, the blend of E2HZ3H and Z2HE3H showed significant antagonistic activities to the attraction of O. nezarae females in the field. We conclude from this study that Z2HE3H is a potent antagonist to the behavioral response of O. nezarae.

The FastSound project is a galaxy redshift survey using Subaru/FMOS to detect Hα emitting galaxies at z ~ 1.3, for the purpose of probing the origin of the accelerated expansion of the universe. The survey has detected ~4,000 galaxy redshifts in a total area of 30 deg2, and detected the redshift space distortion at this redshift range for the first time. The redshift space distortion (RSD) signal will be used to derive a measurement of the growth rate of large scale structure, which will provide a test for modified gravity as a possible origin of accelerated cosmic explansion. Here we present an overview and the current status of the project.

We summarize the progress on the rest-frame optical spectroscopy of quasars at 3 2.5−5μm . This spectral window has been utilized for detecting redshifted Hα emission lines of our high redshift subsample of quasars. From the calculated emission line widths and luminosities we measured supermassive black hole masses using well calibrated optical mass estimators. Science topics regarding optical based black hole masses at high-z are discussed.

This paper presents Hα emission line detections for four galaxies at z > 3.5 made with AKARI as part of the FUHYU mission program. These are the highest-redshift Hα detections to date in star-forming galaxies. AKARI's unique near-infrared spectroscopic capability has made these detections possible. For two of these galaxies, this represents the first evidence of their redshifts and confirms their physical association with a companion radio galaxy. The star formation rates (SFRs) estimated from the Hα lines under-predict the SFRs estimated from their far-infrared luminosities by a factor of ~ 2 - 3. We have also detected broad Hα components in the two radio galaxies which indicate the presence of quasars.

A3-2x/3Al1-zInzO4F: Eux3+ (A=Ca, Sr, Ba, x=-0.15, z=0, 0.1) oxyfluoride phosphors were simply prepared by thesolid-state method at 1050oC in air. The phosphors had the bright red photoluminescence (PL) spectra of an A3-2x/3Al1-zInzO4Ffor Eu3+ activator. X-ray diffraction (XRD) patterns of the obtained red phosphors were exhibited for indexing peak positionsand calculating unit-cell parameters. Dynamic excitation and emission spectra of Eu3+ activated red oxyfluoride phosphors wereclearly monitored. Red and blue shifts gradually occurred in the emission spectra of Eu3+ activated A3AlO4F oxyfluoridephosphors when Sr2+ by Ca2+ and Ba2+ ions were substituted, respectively. The concentration quenching as a function of Eu3+contents in A3-2x/3AlO4F:Eu3+ (A=Ca, Sr, Ba) was measured. The interesting behaviors of defect-induced A3-2x/3Al1-zInzO4-αF1-δphosphors with Eu3+ activator are discussed based on PL spectra and CIE coordinates. Substituting In3+ into the Al3+ positionin the A3-2x/3AlO4F:Eu3+ oxyfluorides resulted in the relative intensity of the red emitted phosphors noticeably increasing byseven times.

Monoalkenyl acetates are used as one of lepidopteran pheromone components. However, (Z)-3-alkenylacetate as pheromone components is rarely known. Among them, (Z)-3-dodecenylacetate is used as pheromone components of Aproaerema anthyllidella and Tecia solanivora. Recently, (Z)-3-dodecenylacetate was identified as one of pheromone components for an insect pest in Korea (unpublisheddata). For the demand of development of mating disruption against thepest, large amount of (Z)-3-dodecenylacetate (Z3-C12Ac) was needed. Here, we reported the synthetic procedures for (Z)-3-decenylacetate (Z3-C12AC). The Grignard reagent from 1-decyne and ethyl magnesium bromide was reacted with ethylene oxide in dry tetrahydrofuran (THF). Thus synthesized 3-dodecyn-1-ol was reduced to (Z)-3-dodecen-1-ol (Z3-C12OH) by hydrogenation over Lindlar’s catalyst. The alcohol was acetylated to desired (Z)-3-dodecenylacetate (Z3-12Ac) with acetic anhydride by general procedures. The yield was 62.6% through the all procedures. Thepurity was 98.0% (by GC-MS). The isomeric purity was >99% (by NMR).
