WFIRST microlensing observations will return high-precision parallaxes, σ(π) . 0.3 μas, for the roughly 1 million stars with H < 14 in its 2.8 deg2 field toward the Galactic bulge. Combined with its 40,000 epochs of high precision photometry (∼ 0.7 mmag at Hvega = 14 and ∼ 0.1 mmag at H = 8), this will yield a wealth of asteroseismic data of giant stars, primarily in the Galactic bulge but including a substantial fraction of disk stars at all Galactocentric radii interior to the Sun. For brighter stars, the astrometric data will yield an external check on the radii derived from the two asteroseismic parameters, the large-frequency separation h
νnli and the frequency of maximum oscillation power νmax, while for the fainter ones, it will enable a mass measurement from the single measurable asteroseismic parameter νmax. Simulations based on Kepler data indicate that WFIRST will be capable of detecting oscillations in stars from slightly less luminous than the red clump to the tip of the red giant branch, yielding roughly 1 million detections.

큰 학자가 떠남에 따라 영문학에 대한 그의 영향과 문학도들에 대한 생각을 하게 한다. 그의 업적 — 특히 『예이츠의 시전집』에 달린 주는 예이츠연구에 있어 필수적이고 권위 있는 목소리가 되었다. 그의 제자들과 동료교수들에 대한 그의 영향은 아주 중요한 멘토의 역할을 했는데, 미래의 학자들의 요청을 거절할 때에도 그러했다.

Insect pests on cruciferous crops and their natural enemies were surveyed during 2009~2011 in Daegwallyeong highland region which has been famous for summer Kimchi cabbage production in Korea since 1970s. Totally 15 insect pests have been reported in cabbage field in Daegwallyeong. Diamondback moth (DBM, Plutella xylostella) imported cabbage worm (Artogeia rapae L.), cabbage armyworm (CAW, Mamestra brassicae L.), cabbage looper (CL, Trichoplusia ni), cabbage sawfly (Athalia rosae ruficornis Jakovlev), and turnip aphid (Liphapis pseudobrassicae (Davis)) were the dominant pest species among the 15 species. For monitoring as well as controlling insects with weak flight, yellow sticky cards (10×15㎝) were used in cabbage fields. The sticky cards were hanged on plastic stick and placed at a 2-5 m distance within cabbage field (1,000㎡). Sex pheromone traps were employed for monitoring and controlling insects with strong flight. The survey result showed that there was significantly reduced pest occurrences in treated, compared to untreated condition. Similarly, The results from the sex pheromone traps were coincident with those of sticky trap. DBM, CAW and CL were found less in the treated than untreated fields; by 67.5%, 70.6% and 44.0%, respectively. Although the control efficacy of such traps was less than that of chemical spray, the use of sticky card trap combined with sex pheromone trap could be useful management tools for controlling insect pests in cabbage fields.

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.

A genus Omosita Erichson, 1843 which belongs to the sap beetle, Nitidulidae, is reviewed from Korea. Two species Omosita colon (Linnaeus, 1758) and O. japonica Reitter, 1874 are previously known from Korea, one species O. discoidea (Fabricius, 1775) is first recorded from Korea. A key to species, re-descriptions, biology, illustrations of both male and female of the genus Omosita are provided.

Two species of the genus Asiacentistes (Hymenoptera: Braconidae) are reported in this study. The genus Asiacentistes is a small braconid group distributed in the East Palaearctic and Oriental regions, which has only two species in the world. One of them, Asiacentistes sinica Chen and Belokobylskij is new to Korea. Diagnosis and distribution in East Asia data are included.

Two species of the genus Cosmophorus (Hymenoptera: Braconidae) are reported in this study. Members of Cosmophorus are known as solitary koinobiont endoparasitoids of adults of barkboring and woodboring Scolytidae. The genus Cosmophorus of the subfamily Euphorinae is small in the size and enigmatic in the ecology, which has been recorded in Holarctic, Oriental, Afrotropical and Australian regions. Only five species are known in East Palaearctic. Among them, Cosmophorus (Cosmophorus) klugii Ratzeburg is new to Korea. Diagnosis and distribution data are included.
