  • The newly sequenced complete mitochondrial genome of the brown marmorated stink bug, Halyomorpha halys($St{\aa}l$) (Hemiptera: Pentatomidae), is a circular molecule of 16,518 bp with a total A+T content of 76.4% and two extensive repeat regions in A+T rich region. Nucleotide composition and codon usage of H. halys are about average when compared with values observed in 19 other published hemipteran mitochondrial genomes. Phylogenetic analyses using these 20 hemipteran mitochondrial genomes support the currently accepted hypothesis that suborders Heteroptera and Auchenorrhyncha form a monophyletic group. The mitochondrial gene arrangements of the 20 genomes are also consistent with our results.

  • 납작먹좀벌과(Platygasteridae)의 큰검정알벌속(Trissolcus)에 속하는 T. japonicus (Ashmead) (썩덩큰검정알벌, 신칭)이 과수원에서 과일에 심한 피해를 일으키는 해충인 썩덩나무노린재의 알에 기생하는 것으로 확인되었고, 생물적 방제인자로써 가능성이 기대된다. 또한 천마큰검정 알벌(T. itoi Ryu)이 북쪽비단노린재 알을, 검은다리큰검정알벌(T. nigripedius Nakagawa)이 알락수염노린재 알을 숙주로 각각 기생하는 것이 확인되었다. 동정을 위한 진단형질 및 영상자료와 한국에 분포하는 큰검정알벌속(Trissolcus)의 종들에 관한 숙주목록을 제공하였다.

  • Stink bug, Canthecona furcellatta (Hemiptera: Pentatomidae), is an important predator of silkworm larvae. Nymphs and adult attack the early stage silkworm larvae and causes about 10-15 per cent loss to silk industry. Synthetic organic pesticides has tremendous impact on minimizing the pest population but repeated and frequent use has created problems of residual toxicity, development of resistance to insecticides, pest resurgence and out break, phyto-toxicity and hazards to non target species and beneficial organism. Silkworms are very sensitive to pesticides; therefore, attempt has made to control the bug population through introduction of its native natural enemies in the silkworm-rearing field. Biological control has tremendous scope in sericulture because it is eco-friendly in nature and non-harmful farmers. Native natural enemies have been screened. Psix striaticeps, Trissolcus spp. and Telenomus spp. have been recorded as the most potential parasitoid against pentatomid bug. Life cycle, sex ratio and other various attributes of the par-asitoids have been recorded. The parasitization potential of the parasitoid is very high and they have the ability to discriminate between parasitized and unpar-asitized host. Mass propopagation technique under laboratory condition has been standaydized.

  • The purpose of this paper is to show the internal structure of the socalled sentential subject constructions in English. The constructions that we examine in this paper are such as It seems that John failed in the syntax exam vs. *That John failed in the syntax exam seems and It really stinks that the Giants lost the World Series vs. That the Giants lost the World Series really stinks. As seen above, the English verb seem does not tolerate the sentential subject. This is in sharp contrast to other English verbs such as suck, blow, bite, and stink, which do allow the sentential subject. There are several issues regarding these constructions. First, where is the sentential subject located? Second, is the sentential subject assigned structural Case? Third, is the sentential subject extraposed or does it remain in its base-generated complement position? Fourth, is the sentential subject a base-generated topic in the specifier position of CP, as Arlenga (2005) claims? In this paper, we argue that sentential subjects are base-generated in the specifier of the verbal phrase in case of stink-type verbs, while they are licensed as a complement to verbs like seem. We also argue that a sentential subject can be raised in the seem-type verbal constructions, if it were part of the complement small clause.

  • 몇 종의 주요 농작물 해충에 대한 식물추출물(cinnamon extract 5% + citronella oil 10% + citrus oil 30% + derris extract 10% + neem extract 20% + penetrating surfactant 25%)의 살란 효과를 분무법으로 검정하였다. 노린재류의 경우 알이 부화하는 과정에서 치사하는 경향을 보였다. 식물추출물(500배액) 처리시 썩덩나무노린재(Halyomorpha halys), 톱다리개미허리노린재(Riptortus clavatus), 홍비단노린재(Eurydema dominulus), 온실가루이(Trialeurodes vaprarorium), 담배가루이(Bemisia tabaci), 파밤나방(Spodoptera exigua), 검거세미밤나방(Agrotis ipsilon)에 대한 최종 살란 효과는 100%로 높게 나타나, 향후 산업화가 가능할 것으로 생각된다.

  • 썩덩나무노린재는 두과작물에서 과실에 이르기까지 다양한 작물을 가해하는 대표적인 다식성 노린재의 일종이다. 과실이 썩덩나무노린재의 발육에 필요한 영양원인지 불필요한 영양원인지 아직도 분명하지 않다. 그리하여 사과와 오렌지의 단독먹이 및 콩-땅콩과의 먹이조합에 따른 썩덩나무노린재의 발육, 사망률 및 증식률을 평가하였다. 썩덩나무노린재 약충은 사과단독먹이에서만 높은 사망률로 성충으로 발육하지 못하였다. 물만 제공한 것은 3령으로 발육하지 못하였고, 사과단독먹이에서 4령으로 발육하지 못하였다. 하지만 오렌지단독먹이에서 14%가 성충으로 우화하였으나, 약충의 발육기간이 약 74일로 가장 길었다. 콩-땅콩과 조합한 먹이에서 노린재의 사망률은 38~44%를 나타내었다. 총 산란수는 169~190개 였으며, 부화률은 81~83%이었다. 따라서 사과는 썩덩나무노린재의 발육에 불완전한 먹이 이었으나, 오렌지는 발육이 지연되기는 하였으나 이루지는 것으로 평가되었다.
