  • A sampling survey was conducted at three reservoirs of Junam wetland ($6.02km^2$) in Korea to identify the wetland insect fauna along with their dominance, diversity, richness and evenness. Methods of monitoring were visual inspection and sweeping in 2010, Malaise trapping in 2011, light trapping and pitfall trapping in 2012. In total, 9,269 individuals (36.3% coleopterans, 21.3% lepidopterans and 13.9% odonates) were collected, belonging to 574 species, 141 families and 14 orders. For the number of species, lepidopterans shared the highest (31.2%), followed by coleopterans (28.0%) and hemipterans (12.9%). Dominant species were Enochrus simulans (Coleoptera) (7.9% of total individuals) followed by Hydaticus grammicus (Coleoptera) (4.3%), Galerucella nipponensis (Coleoptera) (4.1%), Elophila interruptalis (Lepidoptera) (3.1%) and Apis mellifera (Hymenoptera) (2.2%). Total counts of coleopterans, lepidopterans and odonates in the three reservoirs were quite high, but the counts were not significantly different among the reservoirs. Insect diversity index (H') and richness index (RI) of the Junam wetland were 5.04 and 59.10, respectively.

  • In order to investigate the response in fauna and biological communities of terrestrial insects to the vegetation encroachment on the sandbar, species composition, species diversity, functional species traits and community structure of land-dwelling insects sampled by a pit-fall trap were compared at the bare and vegetated sandbar of a typical sand-bed stream, the Naeseong Stream, Korea. Species diversity of the insects was increased but their density was decreased as the riparian vegetation encroached at the sandbar. In particular, indicator species of bare sandbar such as Cicindela laetescripta and Dianemobius csikii, were found at the bar sandbar. The insect communities were clearly classified at the bare and vegetated sandbar according to coverages of riparian plants. The food web of the bare sandbar was composed of detritus - detritivore and scavenger - predator consisted mainly of Coleoptera. On the other hand, the food web of the vegetated sandbar was composed of plants - sucking and chewing herbivore - parasitoid and predator. These results showed that biodiversity of terrestrial insects was increased, food web was changed from grazing to detritus food chain, and insect fauna specific bare sandbar disappeared as the riparian vegetation invaded on the sandbar of a sand-bed stream.

  • Cecidomyiidae (Diptera) consists of six subfamilies, which are divided into three groups according to larval ecological habits (phytophagous, mycophagous, and zoophagous). The five basal subfamilies of Cecidomyiidae consist entirely of mycophagous species, with approximately 1500 species described worldwide and 29 previously known to occur in Korea. In this study, 37 named species (1 Lestremiinae, 29 Micromyinae, 4 Winnertziinae, and 3 Porricondylinae species) are newly reported from South Korea. We excluded Lestremia yasukunii Shinji from the list of Korean mycophagous cecidomyiids as it is a nomen nudum. Therefore, we herein officially recognize 65 species, 30 genera, and four subfamilies for the Korean mycophagous cecidomyiid fauna. We also provide diagnoses and photographs to aid species identification and discussion on the four years of gall midge taxonomic inventory in South Korea.

  • A two-year survey on the insect fauna of Dokdo located at the eastern end of Korean territory, was carried out from 2009 to 2010. A total of 11 Orders 65 Families 131 Genera 133 Species of insects was reported to exist in Dokdo by Park et al. (2012). This study was focused on the collection of small insects (under 1 mm in body length) in Dokdo. Form the collection, the comparison of the species composition to past records in Dokdo was carried out.

  • The subfamily Pimplinae is one of the largest groups of the family Ichneumonidae, currently 1,737 species in 77 genera worldwide. In Korea, 120 species in 33 genera have been recorded. The South Korean species of the subfamily Pimplinae Wesmael, 1845 (Hymenoptera: Ichneumonidae) are the focus of this study. Here, six species are newly added in the South Korean fauna: Aravenator kamijoi Momoi, Chablisea varicolor Liu, He & Chen, Clistopyga arctica Kusigemati, Liotryphon cydiae (Perkins), L. strobilellae (Linnaeus), and Zaglyptus semirufus marginatus Kasparyan. Of these new taxa, two genera (Aravenato and, Chablisea) belonging to the tribe Ephialtini are also newly recorded from South Korea. We present a key to species of South Korean Clistopyga, Liotryphon, and Zaglyptus, diagnosis, photographs, and distribution. As a result of this study, the Korean fauna of Pimplinae is now known to consist of 126 species in 35 genera. All Pimplinae specimens are kept in the collections of the Geolim Entomological Institute (GEI), Daegu, South Korea.

  • This study was carried out to know the insect fauna of turf grass area in forest. In Korea, graves and public cemetery in mountain areas are usually covered by turf grass which were mainly examined. There were 86 species belonging to 77 genera of 39 families in 11 orders. Among them, site 3 had highest occurrence (38%), second was site 2 (36%) and in the last place was site 1 (26%). Hemiptera revealed best species composition (29.1%) and came Coleoptera (19.8%), Orthoptera (15.1%), Lepidoptera (12.8%) and Odonata (5.8%) etc. The reason why Hemiptera and Orthoptera are mainly found in these areas is because they usually feed on short plants that grow in there. Taxonomic species composition, occurrence ratio by site and species and comparison analysis were provided.

  • The pine mushroom fruit body have a harvest only from natural pine forest instead of artificial culture like other edible mushrooms until now on. We investigated the interrelationship between pine mushroom colonies and insect/invertebrates fauna, and changes of their seasonal populations. Two famous pine mushroom producing district were selected on Bong-wha and Gan-sung Eup, and were surveyed on the ground and in the soil with/without pine mushroom hyphae per month from June to November, 2005. There was some difference in collected Insects and invertebrates between two producing districts. Total number of collected species and individuals were 73 and 22, and 63 individuals with 19 species in Bon-wha and Gan-sung area, respectively. Otherwise, there were many mites and nematodes were living in soil with mushroom hyphae. The population densities of mites were Increased to November from June, however, the population of nematodes were fluctuated with low in hot weather and high in cool.
