Study on four genera of Diplazontinae (Hymenoptera: Ichneumonidae) in South Korea with description of two new species

Ekaterina N. Balueva,이종욱 한국곤충학회 2016 Entomological Research Vol.46 No.1

Of 16 genera of the subfamily Diplazontinae occurring in the Eastern Palearctic region, 11 were previously recognized from South Korea. In previous studies we reviewed eight Diplazontinae genera were reviewed. In this current paper, one genus, Enizemum Förster, is recorded from this country for the first time with one newly described species, E. nigrocoxatum Balueva and Lee sp. nov. Also other three genera, Homotropus Förster, Syrphoctonus Förster and Syrphophilus Dasch, are reviewed here. Here we provide key and diagnosis to eight species of Homotropus including one new species, Homotropus sepiatus Balueva and Lee sp. nov., and key and diagnosis to two species of genus Syrphoctonus and two species of genus Syrphophilus.

Review of subfamily Diplazontinae (Hymenoptera: Ichneumonidae) from South Korea with six unrecorded genera and a new species

Ekaterina N. Balueva,이종욱 한국곤충학회 2014 Entomological Research Vol.44 No.4

Of the 16 genera of the subfamily Diplazontinae occurring in the Eastern Palearctic region, 11 genera are recognized from South Korea. Specifically, four genera (Campocraspedon Uchida, Diplazon Nees, Syrphoctonus Förster and Woldstedtius Carlson) are previously recognized from South Korea, whereas the other seven genera are recorded from this country for the first time. A key to the 16 genera of Diplazontinae occurring in the Eastern Palearctic region is provided. Six genera of Korean Diplazontinae (Bioblapsis Förster, Campocraspedon Uchida, Eurytyloides Nakanishi, Phthorima Förster, Promethes Förster and Sussaba Cameron) are reviewed here. Species of these genera rarely occur in the Eastern Palearctic region with small numbers of collected samples (excluding genus Sussaba). Here we provide diagnosis for seven species of Diplazontinae and one new species, Eurytyloides koreanus Balueva and Lee sp. nov., has been described.

A new species of the genus Probles Förster (Hymenoptera: Ichneumonidae: Tersilochinae) from South Korea

Ekaterina N. Balueva,Andrey I. Khalaim,이종욱,김기범 한국응용곤충학회 2014 Journal of Asia-Pacific Entomology Vol.17 No.3

The newspecies Probles (Euporizon) leei Khalaim, Balueva & Kimsp. nov., is described from South Korea. The newspecies is characterized by a reduction of the groove between glymma and the ventral part of postpetiole,whereas other species of Probles typically have a well-developed groove. This is the most abundant species ofProbles in South Korea, where it accounts for over half of all collected specimens of the genus.

Three New Species of the Genus Probles Förster (Hymenoptera: Ichneumonidae: Tersilochinae) from South Korea

Ekaterina N. Balueva,Andrey I. Khalaim,Ki-Beom Kim,Jong-Wook Lee 한국응용곤충학회 2013 한국응용곤충학회 학술대회논문집 Vol.2013 No.10

Probles is apredominantly Holarctic genus with about 44 species in the Palearctic region (Yu et al. 2012). Palearctic fauna of Probles is rather irregularly studied: West European species were revised by Horstmann (1971, 1981; Horstmann and Kolarov 1988), and Palearctic species of five small subgenera, Microdiaparsis Horstmann, Probles s. str., Rhynchoprobles Horstmann, and Rugodiaparsis Horstmann, were reviewed by Khalaim (2003), whereas the most species rich subgenus, Euporizon Horstmann, is virtually unknown outside Europe. Only two species of Euporizon, P. (E.) sibirica Khalaim, 2007 from Mongolia and Russian Siberia and P. (E.) vulnifica Khalaim & Sheng, 2009 from the Palearctic part of China, are known to occur in the East Palearctic region, and one Oriental species, P. (E.) vietnamica Khalaim, 2011, was recently described from Vietnam (Khalaim, 2011; Khalaim and Sheng 2009). Some species of Probles were recorded as parasitoids of the beetle families Ciidae, Curculionidae, Endomycidae, and Melandryidae in Europe (Horstmann 1971, 1981). In this paper, we describe three closely related new species of Euporzon belonging to one species-group. Three closely related species of the genus Probles Förster, P. fulgida sp. n., P. korusa sp. n., and P. rukora sp. n. differ from other Palearctic species of the genus based on a combination of long and weakly sinuate apically ovipositor and short temple. A portion of the key for identification of this species-group is provided here.

Study on two unrecorded genera, Barycnemis Förster and Phradis Förster (Hymenoptera: Ichneumonidae: Tersilochinae), from South Korea

Ekaterina N. Balueva,김기범,Andrey I. KHALAIM,이종욱 한국곤충학회 2013 Entomological Research Vol.43 No.3

Six genera of the subfamily Tersilochinae (Barycnemis, Diaparsis, Gelanes, Phradis, Probles and Tersilochus) are recognized in South Korea. Two genera, Diaparsis and Tersilochus, were previously recognized from South Korea, whereas the other four genera are recorded from this country for the first time. All genera found in South Korea, except the almost cosmopolitan Diaparsis, are entirely or predominantly Holarctic. A key to the six genera of Tersilochine occurring in South Korea is provided. Two genera of Korean Tersilochinae (Barycnemis and Phradis) are reviewed here, and a key to the other four species (B. bellator, B. dissimilis, P. kyushuensis and P. nikishenae) is provided in this paper.

Natal host에 따른 콜레마니진디벌(Aphidius colemani)의 산란력과 숙주 크기 선호성의 차이

김태호,오승호,백운기,Balueva Ekaterina N.,안승락 한국응용곤충학회 2011 한국응용곤충학회 학술대회논문집 Vol.2011 No.05

콜레마니진디벌(Aphidius colemani)은 진딧물과의 생물적 방제자로서 전세계적으로 널 리 이용되고 있으며, 경제적으로도 대단히 가치가 높은 분류군이다. 그러나 인위적으로 동일 한 숙주에서 수 세대에 걸쳐 누대사육 될 경우 이들의 형태적 유연성은 감소하고, 숙주의 생리 적 질에 따라 크기와 충질에서도 많은 차이를 나타내게 된다. 또한 숙주 선택 행동은 natal host로 부터 비롯된 표현형적 한계로 인해 제약을 받고, 공급되는 숙주의 령기 편차에 따라 기 생률은 현저한 차이를 보인다. 본 연구의 목적은 대량사육 되는 콜레마니진디벌의 도태를 방지하고 생물적 방제에 적합 한 품질을 지속적으로 유지시키기 위한 방법을 모색하는 것으로, natal host의 인위적 조절로 인해 발생하는 현상을 확인하는 것이다. 이에 본 연구에서는 서로 다른 두 natal host 종에서 발생한 콜레마니진디벌 개체군을 대상으로 이들의 크기 변화를 측정하고 복숭아혹진딧물 (Myzus persicae)에 대한 각각의 산란력, 성충 크기에 따른 숙주의 크기 선호성, 그리고 두 콜 레마니진디벌 개체군이 혼합되었을 때 생산량의 차이를 확인하였다. 온도 25℃, 상대습도 70%RH, 광조건 16L:8D에서 복숭아혹진딧물에 대한 콜레마니진 디벌의 일일산란력(eggs/1 female/1 day)을 조사한 결과, natal host가 복숭아혹진딧물인 콜 레마니진디벌은 66.4±33.9eggs, 아카시아진딧물(Aphis craccivora)인 콜레마니진디벌은 111.2±51.0eggs으로 전자보다 산란력이 높은 것으로 확인되었다. 기생자의 성충 크기에 따 른 숙주 크기 선호성에 대해 조사한 결과, 복숭아혹진딧물에서 발생한 콜레마니진디벌 개체 군의 평균 hind tibia 길이는 433.2±26.5㎛로 몸길이가 0.85±0.22㎜인 복숭아혹진딧물을 선호하였으며, 아카시아진딧물에서 발생한 콜레마니진디벌의 hind tibia 길이는 516.1±24.0 ㎛로 1.21±0.26㎜ 크기를 선호하는 것으로 나타났다. 따라서 natal host에 따라 콜레마니진 디벌의 성충 크기는 차이가 있으며, 이들의 크기와 비례하여 숙주 크기 선호성 또한 차이가 있음을 확인하였다. 이와 같은 특성을 이용하여 두 개체군이 혼합된 콜레마니진디벌을 복숭 아혹진딧물에 기생시킨 결과 0.13㎥ 크기의 사육 cage에서 55,000 마리의 콜레마니진디벌 이 생산되었으며, 이는 혼합하지 않은 두 대조군 보다 약 30% 많은 개체수로 확인되었다. 본 연구의 결과, 콜레마니진디벌의 대량 생산 체계에 있어 natal host의 인위적 변경은 콜레마 니진디벌의 생리적 특성 및 충질을 변화시켜 산란력과 생산력을 증진시킬 수 있는 중요한 요 소가 되는 것으로 판단된다.
