The Genus Psectra is a small group of Hemerobiidae, and Psectra diptera is one of the rare and attractive species in this group because of hindwing variation. They are well known to have their hindwing reduced, similar to flies, depending on their habitat environment. We report Genus Psectra and Psectra diptera, new records from Korea. We provide brief descriptions and photos of adults and genitalia.

Mantidflies or Mantid lacewing (Mantispidae) is a morphologically interesting group of Neuroptera. This group is a general predator of arthropods and is equipped with raptorial forelegs similar to praying mantis. In Korea, only three species, Climaciella quadrituberculata, Mantispa harmandi, and Mantispilla japonica, are recorded until now. Here we report Genus Necyla and Necyla formosana, new records in Korea. We provide diagnostic character and photos of adult and genitalia.

Age-stage two sex life table was constructed for a predatory lacewing, Chrysoperla carnea feeding on 3 different canola feeding aphids; mealy cabbage aphids, Brevicoryne brassicae (L.), mustard aphid, Lipaphis erysimi (Kaltenbach) and green peach aphid, Myzus persicae (Sulzer). The experiment was performed under laboratory conditions at 25± 1oC and 65 ± 1% RH. The immature development duration was shortest on M. persicae (17.3 days). While, C. carnea completed its immature developmental period in 21.1 days, which was longest among other, tested aphids. Similarly, survival of C. carnea was higher on feeding M. persicae and lowest on L. erysimi. Female egg laying of predator was also higher on M. persicae, followed by B. brassicae and L. erysimi. These results show that M. persicae favors the quick development and higher reproduction of C. carnea as compared to B. breassicae and L. erysimi. This information is useful in relation to mass rearing of C. carnea and in biological control of canola aphids by using C. carnea.

Coniopteryginae is a highly diversified group of Coniopterygidae. In Korea, only two species, Semidalis aleyrodiformis and Conwentzia pineticola, are recorded. Here we report two additional species of Coniopteryginae, Coniopteryx pallescens and Conwentzia sinica, as new records in Korea. Brief descriptions, photos of adults and male genitalia as well as COI barcode sequences are provided.

Conwentzia와 C. pineticola를 한국 미기록속 및 미기록종으로 보고한다. 본 종의 성충에 대한 간략한 기재와 성충 사진 및 생식기 사진과 함께, 16S rRNA 와 COI 염기서열을 제공한다.

Berothidae is one of the uncommon group of Neuroptera. The family currently include about 22 genera and 100 species in the world. The genus Isoscelipteron include about 20 species in the world, with the distribution covering Eurasia. Several species of this family are known to be a termite predator during larval stage. We collected Isoscelipteron pectinatum adult, which is a new species record in Korea, which is in fact a new family record as well. Here we provide a brief description, photos of adult and male genitalia, and DNA barcode sequence based the specimen examined.

Even with the tiny body size, Coniopterygidae is the fourth largest group of Neuroptera. There are currently 23 genera and 560 species recorded in the world. They have a tiny-sized body, and their wings are covered with whitish wax powder and they are fairly well-known natural predators of small insects such as scale insects, aphids, and mites. Genus Cowentzia is one of the characteristic groups of Coniopteryginae; they have conspicuously reduced hind wings than other groups have. The genus contain about 14 species in the world. Here we present Conwentzia, a new genus record, with Conwentzia pineticola in Korea. We provide a brief description, photos of adult and male genitalia, and 16S rRNA sequence based the specimen examined.

Chrysopidae is a cosmopolitan group of Neuroptera, with 85 genera and 1,200 species recorded in the world. Genus Nineta is a small group of the family, with almost 20 species recorded worldwide. They can be recognized by large sized body than that of other genera. In Korea, only one species, Nineta vittata (Wesmael, 1841) has been recorded so far. Here we present Nineta itoi, another new record, in Korea. Here we provide a brief description, photos of adult and male genitalia, COI barcode sequence, and a key based on diagnostic characters.

Coniopterygidae is the fourth largest group of Neuroptera. There are currently 23 genera and 560 species recorded in the world. They have a tiny-sized body, and their wings are covered with whitish wax powder. In Korea, only one species, Semidalis aleyrodiformis has been recorded in Coniopteryginae. Recently we collected two additional species, each belonging to Spiloconis and Coniocompsa in Aleuropteryginae. In this poster, Spiloconis sexguttata and Coniocompsa postmaculata are newly recorded in Korea. Morphologically Spiloconis sexguttata has reddish colored body with some flagella segments black while Coniocompsa postmaculata has blackish pattern on forewing. We provide brief descriptions, photos of adults and male genitalia and DNA barcode sequences based the specimens examined.

그동안 국내 Drepanepteryginae 아과(낙엽날개뱀잠자리붙이아과; 신칭)에는 오직 Neuronema albostigma만이 기록되어 있었으나, 이번 연구를 통해 국내 미기록속인 Drepanepteryx와 이 속에 포함되는 미기록종 Drepanepteryx phalaenoides (낙엽날개뱀잠자리붙이; 신칭)를 새롭게 보고 한다. 이 종에 대한 간략한 기재와 속내 분류키, COI 바코드 염기서열, 그리고 성충 및 수컷 생식기의 사진을 제공한다.

Hemerobius contumax Tjeder, 1932 is a well known species of Hemerobiidae (Neuroptera) in Europe and Middle East countries, but has never been found in Asia. In Korea, a total of eight hemerobiid species have been recorded including the genus Hemerobius. So far only two species, Hemerobius humulinus and Hemerobius harmandinus are reported. Recently we collected another species of which the specific identity is in question: morphologically very similar to Hemerobius contumax but with c.a. 5% difference in COI barcode sequences. With 5% genetic difference, it may be easily considered as a different species from H. contumax. However, the adult image from the specimen sequenced for H. contumax found in the BOLD site is morphologically slightly off from the usual H. contumax, and there is still an investigation needed to confirm its specific identity. In any case, here we provide a brief description, photos of adult and male genitalia and DNA barcode sequence based the specimen examined.

그 동안 한국 풀잠자리과 Italochrysa속은 오직 1종만이 기록되었으나, 한국 미기록종인 몸노랑풀잠자리(Italochrysa nigrovenosa Kuwayama, 신칭)의 국내 분포를 추가로 보고한다. 이 종에 대한 간략한 기재와 속내 분류키, 그리고 암컷 성충과 생식기의 사진을 제공한다.

The Genus Drepanepteryx Leach, 1815 and Drepanepteryx phalaenoides (Linné), 1758 (Neuroptera:Hemerobiidae) are newly reported to Korea. Only one species, Neuronema albostigma have been reported in Korea as a species of Drepanepteryginae. In this study we report another species, Drepanepteryx phalaenoides and provide photos of adult and male genitalia based the specimen examined.

본 연구는 온도(15, 20, 25, 30℃), 습도(70 ± 10%), 광주기(16L:8D)에서 갈고리뱀잠자리붙이의 생물적 특성을 조사하기 위해 수행되었다. 알에서부터 번데기까지의 발육영점온도 및 유효적산온도는 각각 9.6℃ 및 270.3일도였다. 25℃에서 갈고리뱀잠자리붙이의 알 기간은 4.4일, 유충은 5.5일, 번데기는 6.9일이었다. 암컷 성충의 수명은 34.9일, 산란 기간은 28.7일이었고, 총 산란수는 515.2개, 1일 최대 산란수는 54.8개였다. 25℃에서 갈고리뱀잠자리붙이에 의한 싸리수염진딧물의 1령, 2령, 3령 및 성충의 일일 포식량은 각각 18.9, 47.2, 57.7 및 91.0마리이었다. 따라서 갈고리뱀잠자리붙이는 진딧물의 포식성 천적으로 이용이 가능할 것으로 여겨진다.

Biological control of Pseudococcus comstocki (Kuwana) with new indigenous natural enemy (Chrysoperla nipponensis (Okamoto)) was carried out on tropical plant (Trachycarpus fortunei (Hook)) from May to July in 2013. Control experiments were conducted at Tropical Plant Resources Research Center of Korea National Arboretum, Pocheon, Korea. Chrysoperla nipponensis was released once (20 larvae/m2) to control Pseudococcus comstocki on 11st May in 2013. We investigated the density of leaf-feeding P. comstocki at intervals of approximately 7 days after introducing their natural enemy, C. nipponensis. The densities of P. comstocki were suppressed 22.4% (after 4 weeks) and 8.2% (after 6 weeks) after introducing C. nipponensis.

Yellow tea thrip (Scirtothrips dorsalis Hood (Thysanoptera: Thripidae) is anthophilous pests of many crops worldwide including five flavor berry. And the mealy bug (Pseudaulacaspis cockerelli (Cooley) (Hemiptera: Diaspididae)) is one of the hardest pests to control. Its body is covered with white waxy threads, which often make a chemical pest control useless. Five flavor berry (Schisandra chinensis Baill) is used in traditional Chinese medicine. So, the development of biological control against the major pest on five flavor berry is of great interest. In this work, a treatment of Chrysoperla nipponensis (Okamoto) was applied to five flavor berry fields infested by P. cockerelli and a treatment of Amblyseius swirskii Athias-Henriot was applied to two types of five flavor berry fields infested by S. dorsalis. Even though our tests found significant differences between the two culturing method(sod culture, nonwoven type mulching), the treatment of biological control agents decreased or a little increased the fruit damage, which was comparable to the chemical insecticide treatment. In the sod culture experiment, thrip population was significantly low and increased at a lower rate than in the nonwoven type mulching. It may be suggested from these results that A. swirskii and C. nipponensis as IPM program and sod culture could be incorporated into the integrated pest management system on five flavor berry.

The family Sisyridae is very unique in that their larvae are aquatic and feed on sponges. The family has not been described in Korea until one species, Sisyra nikkoana (Navas), of Sisyridae was reported in the Illustrated Book of Aquatic Invertebrates in Agricultural Ecosystem (Rural Development Administration, 2008). However, this short description includes a misidentified adult image, and here we provide its full description in morphology with its wing pattern and male genitalia, as well as its COI barcoding information. We suggest its Korean name, 해면풀잠자리(해면풀잠자리과) as they feed on sponges.

Study of the Korean Chrysopidae has been scarce and only 11 species in 6 genera have been recorded so far(Checklist of Korean Insect, 2010). Genus Italochrysa has been a monotypic genus in Korea with I. japonica. Here we report Italochrysa nigrovenosa as another species of Italochrysa found in Korea. Images of adult and it’s genitalia information are provided.

Micromus variegatus (Neuroptera: Hemerobiidae) is reported here as new to South Korea. In addition, three other hemerobiid species recorded only the collection data, Hemerobius harmandinus, Sympherobius tessellatus and S. domesticus are also reported with a brief description, images of the adult and wings, and its Korean common name. With four previously reported species in Korea, there are eight species of the family Hemerobiidae from Korea.
