  • Tropical fire ant, Solenopsis geminata (Fabricius) is distributed over the tropical and temperate areas. It is a polyphagous pest attacking to various plant and causes the pain to the people doing outdoor work. So it is known for a hygienic pest to human being, especially the people doing outdoor activities. It can cause severe pain to human, even with just a bite. Of particular concern is the possibility of its settlement in this country, if it invade to the farmlands and/or forests of Jeju Island and southern part in Korea. It is listed as a regulated pest in Plant Quarantine Act of Korea. This ant is usually imported through a ship and early settled in the port area where it is already distributed. Recently its distribution is rapidly spreading into Southeast Asia and southern part of China. In Korea, it was detected the one time in 1990s, but was detected the ten times from 2000 to 2006 by an imported plant quarantine process. Therefore, we would like to provide some information on the species, including morphology, distribution, host plant, damaged symptom and its general bionomics, which will be useful data for plant quarantine process and control.

  • Toxicities of 34 agricultural insecticides was tested against Monomorium pharaonis workers by diet dipping method. Ten insecticides among them, bifenthrin, chlorpyrifos, chlorpyrifos-methyl, cypermethrin, dichlorvos, fenthion, fenitrothion, methidathion, pirimifos-methyl, and phenthoate showed 100% rapid mortality. $LC_{50}$ (ppm) values of selected insecticides were appeared on the order of pirimifos-methyl (0.33), chlorpyrifos-methyl (0.76), phenthoate (1.70), bifenthrin (1.78), dichlorvos (2.50), cypermethrin (9.92), chlorpyrifos (22.21), fenitrothion (36.58), fenthion (40.96), and methidathion (64.34). $LT_{50}$ (day) values by diet dipping method showed that dichlorvos, benfuracarb and cypermethrin acted more rapid than boric acid and hydramethylnon. The values of the former three were 0.25, 0.38 and 0.27 days, and those of the latter two were 3.4 and 2.6 days, respectively. In persistance effect tests, chlorpyrifos-methyl, fenthion and methidathion showed over 90% insecticidal activity for 13 days.

  • In order to investigate the population structure and dynamics of halophilous springtails and ants at seashores in Korea, we made quantitative collection from three different sites having different vegetation and environment. The pH, salinity, and electric conductivity of the three sites were measured in order to find environmental factors influencing on their species composition and distribution. In view of the results so far obtained, the species composition and distribution of springtails seemed to depend not so much on pH and vegetation as on soil texture and salinity. On the other side, ant populations seemed to depend on vegetation in sand area and on inundation in both sand area and salt marshes. In all investigated sites, the species diversity in supra littoral zones was higher than in intertidal zones, and among intertidal zones of sand beach and salt marshes it was the highest at the upper zone of the sand beach.

  • The red imported fire ant is considered one of the most notorious invasive species because of its adverse impact on both humans and ecosystems. Public concern regarding red imported fire ants has been increasing, as they have been found seven times in South Korea. Even if red imported fire ants are not yet colonized in South Korea, a proper quarantine plan is necessary to prevent their widespread distribution. As a basis for quarantine planning, we modeled the potential distribution of the red imported fire ant under current climate conditions using six different species distribution models (SDMs) and then selected the random forest (RF) model for modeling the potential distribution under climate change. We acquired occurrence data from the Global Biodiversity Information Facility (GBIF) and bioclimatic data from WorldClim. We modeled at the global scale to project the potential distribution under the current climate and then applied models at the local scale to project the potential distribution of the red imported fire ant under climate change. Modeled results successfully represent the current distribution of red imported fire ants. The potential distribution area for red imported fire ants increased to include major harbors and airports in South Korea under the climate change scenario (RCP 8.5). Thus, we are able to provide a potential distribution of red imported fire ant that is necessary to establish a proper quarantine plan for their management to minimize adverse impacts of climate change.

  • In this study, the distribution, bait preference, hosts, symbionts, habitat status, and cytochrome c oxidase subunit-I sequences of the ant Linepithema humile were analyzed. This species habitat comprised approximately 1.5 km along stone crevices, flower gardens, roadsides, and container yards in the vicinity of Busan station, Korea. Feeding activity of this species was confirmed in 9 species of 7 families of plants. Which was approximately 14% of total flora (63 species of 37 families) in the studied area. Particularly, it was observed that Dendranthema indicum and Camellia japonica were the most frequently visited. Further, we verified that they interacted with four species of aphids. We identified 22 species of ants (17 genera, 4 subfamilies) inhabiting the Busan station area, including L. humile, Tetramorium tsushimae, Nylanderia flavipes and the alien species Paratrechina longicornis. In areas where L. humile was the dominant species, the habitat of local native ants was reduced by approximately 30%. Bait preference was ranked in the following order: jelly, water with glucose (25%), and yogurt, with the highest preference for baits containing sugar and protein. The 630-bp cytochrome c oxidase subunit-I sequences of the local L. humile populations were 99% identical to those of L. humile in the National Center for Biotechnology Information database, and the Argentine ants that invaded Korea had a sequence identical to that of other invasive populations from China, Japan, and New Zealand. As L. humile rapidly increases due to domestic adaptation, continuous monitoring and control strategy for eradication are needed to protect domestic biodiversity.

  • Thinning treatment has a huge effect on understory and litter structures in forest ecosystem, and the resulting changes may impact some arthropod groups such as plant-feeders and detritivores. This study was carried out to find a change in arthropod abundance and their structures in relation to the thinning activity in a Pinus koraiensis plantation in Chuncheon, Korea, where thinning was conducted twice: in 1998-2000 (old-thinning) and 2007 (new-thinning). Arthropods were collected using pitfall traps in 2006 and 2008. Effects of old-thinning on change of abundance and community structure of arthropod were significant, but the effects of new-thinning were not significant. The most significant thinning effect was found in detritivores, followed by plant feeders, but the effect was hardly significant in predators. Among detritivores the changes in abundance was diverse. The abundance of orthopteran plant-feeder increased, but Curculionidae declined after thinning. There was not different in abundance of total arthropods between thinned and unthinned areas because the difference may have cancelled each other out by increased or decreased abundance of taxa. Community structures of arthropods were most greatly affected by years, followed by the old-thinning, but the new-thinning did not affect community structures.

  • To search for the co-relationships between insect-pollinators and the plant species of Asteraceae, insects visiting in flower and the flowers in Korea, were studied from April 2010 to October 2011. The sum of flower visiting degrees are shown 38 in Lepidoptera, 38 in Diptera, 36 in Hymenoptera, and the lowest 6 in Coleoptera, respectively. 65 insect species are identified pollinators, Hymenoptera 13 species(Apidae 11 sp., Formicidae 2 sp.), Lepidoptera 29 species(Pieridae 5sp., Nymphalidae 12 sp., Satyridae 3 sp., Hesperirdae 3 sp., Lycaenidae 2 sp., Danaidae 1 sp., Moth 2 sp.), Diptera 16 species(Tachinidae 1 sp., Syrphidae 12 sp., Muscidae 1sp., Others 2 sp.), and Coleoptera 6 species(Cetoniidae 1 sp., Cermbycidae 3 sp., Chrysomelidae 1 sp., Mordellidae 1 sp.). 31 pollinator species visits the flower of $Erigeron$ $annuus$, next 15 pollinator species does the flower of $Eupatorium$ $japonicum$, and then 13 pollinator species does the flower of $Aster$ $ageratoides$. Only 2 pollinator species visit the flower of $Tephroseris$ $kirilowii$, $Ixeridium$ $dentatum$, $Inula$ $britannica$ var. $japonica$, $Carduus$ $crispus$, $Ligularia$ $fischeri$, $Ainsliaea$ $acerifolia$, $Synurus$ $deltoides$, $Cirsium$ $setidens$, $Crepidiastrum$ $enticulatum$ and $Dendranthema$ $boreale$. Pollinators of Lepidoptera visit more frequently white flower than yellow or purple one. This study found out that mutualisic relations between plants and insect pollinators is carried out in Korea.
