For the study of ant fauna in Mt. Kyeryongsan, we selected three areas and collected 317 colonies nine times from 1986 to 1990. The communities of ants were composed of 3 subfamilies, 23 genera and 45 species. Among them, Solenopsis sp. was an unrecorded species in Korea. The number of ant species distributed in each area was almost the same, and the species distributed uniformly in the nine subareas were Paratrechina flavipes and Aphaenogaster japonica. The number of species collected in the only one subarea were ten, and six among them were collected in the area of Sinwonsa temple, the westward slope. It is remarkable that Camponotus tokioensis, which is known to be distributed only in the island and coast so far, is found to be distributed in the area of Sinwonsa temple as well.

One new species of the genus Myrmica was found from Mt. Moak in Chonbuk, Korea. It was named as Myrmica cadusa n. sp. on the basis of external shape of the antennal socket, which is jar-shaped. Accordingly Korean Myrmica now includes 13 species in total.

To find out ant fauna in the Mt. Chiak, collection tours were taken in three courses for two years. As a result, The ant fauna of Mt. Chiak were confirmed to be 45 species belonging to 23 genera under 4 subfamilies. Among them, ten species were new to Gangweon-province and Myrmica sp. 6 was new to Korea. Ants fauna of Gangweon-province at together became 74 species under 28 genera. In Ponerinae, ants fauna have become 5 species under 4 genera, in Myrmicinae, 20 species under 13 genera, in Dolichoderinae 1 species under 1 genera and in Formicinae 19 species under 5 genera.

Faunistic survey of ant was carried out twice in April and July 1994 from Is. Sohuksando located in westsouthern area in Korea. Thirty-seven species were identified ut of Five hundred and thirty seven colonies collected. Among them, Camponotus nawai Ito and Smthistruma incerta Brown are found to be the first record from Korea.

At the Mt. Mirok, Chonbug, Korea, ants have been collected from May, 1992 to April, 1998. Examining all the collections, they were classified as 25 species, 21 genera of 13 tribes under 3 sufamilies.

The ant fauna in Mt. Gariwangsan was composed of 39 species 24 genera 5 subfamilies. The collected ants in Mt. Gariwangsan were Subfamily Myrmicinae(16 species 11 genera), Subfamily Formicinae(15 species 5 genera), Subfamily Ponerinae(6 species 4 genera), Subfamily Amblyoponinae(1 species 1 genera), and Subfamily Dolichoderrinae(1 species 1 genera). Ant fauna by vegetation in Mt. Gariwangsan, 36 species 23 genera were collected in broadleaf tree areas in which Quercus mongolica, Fraxinus rhynchophylla, Tilia amurensis, and Cornus controversa were dominant species. Paratrechina flavipes and Myrmica kotokui were dominant species. 13 species 12 genera were collected only in broadleaf tree areas. In the coniferous tree areas where Pinus densiflora, Pinus korainensis, and Larix kaempferi were dominant, 24 species 15 genera of ants in total were collected. Pachycondyla chinensis and Paratrechina flavipes were dominant species. 4 species 3 genera were collected only in the coniferous tree areas. Paratrechina flavipes was dominant even in the areas in which Camponotus japonicas and Formica japonica had been assumed to be dominant. Specifically, the higher the land was, the rarer Ponerinae and Dolichoderinae were observed. The common species observed in both areas were 20 species 13 genera. Of these ants, Paratrechina flavipes(Subfamily Formicinae) and Myrmica kotokui(Subfamily Myrmicinae) were distinctive ants. With regard to the current state of colony of these species, Paratrechina flavipes was dominant in lowland areas. Myrmica kotokui, on the other hand, was dominant in highland areas.

Solenopsis japonica, which is belonging to Formicidae in Hymenoptera, is a native ant species in Korea. However, it had not been studied for cold hardiness of S. japonica to understand on its overwintering mechanisms in field so far. Cold tolerance on developmental stages was measured at different cold temperature with various exposure times. Workers showed more survival at 5℃ and 10℃ compared with other stages and elevated cold tolerance when workers were exposed at 15℃ for more than 12h incubation as a rapid cold hardening (RCH) condition. RCH treatment not only increased survival of workers at cold temperatures, but also decreased supercooling point (SCP) and freezing point (FP). RCH group increased the survival rate by 44% at 10℃ compared with Non-RCH group. SCP and FP were depressed from -10.0 to -14.2℃ and from -11.3 to -15.3℃, respectively, after RCH treatment. Cold temperature increased expression level of cold- and stress-related genes such as glycerol kinase and heat shock protein. These results indicate unacclimated cold tolerance of S. japonica and its acclimation to low temperature by RCH.

The ghost ant Tapinoma melanocephalum is a common household pest worldwide. The present study examined the occurrence of the species in urban homes in Korea. During the period of September 2014 to January 2016, T. melanocephalum workers were collected from 58 homes at 29 different localities using bait traps with 10% sugar solution. The species was widely distributed throughout urban homes at 29 different localities, and the indoor occurrence of T. melanocephalum was highest in Seoul (32.7%) and metropolitan areas of Gyeonggi-do (Province) (29.3%). The indoor incidence rate of T. melanocephalum peaked in September (22.8%), remained moderate from October through April, and peaked again in May (15.7%). In contrast, a low incidence was observed from June to August (7.0%). The present study provides evidence that native ants, such as T. melanocephalum, are potential indoor pests of homes in Korea throughout the year.

The present study was developed in order to evaluate the effect of five essential oils on the workers of the leaf-cutting ants; Atta sexdens rubropilosa and Acromyrmex subterraneus molestans by contact with a treated surface and ingestion with a treated leaves.. The essential oils of cinnamon, clove and mustard had generally more effective with 5, 10 and 15% concentrations after 24, 48, 72 and 96 h against workers of A. sexdens rubropilosa and A. subterraneus molestans in contact bioassay, but mustard was the most effective in ingestion bioassay on both species. On the other hand, there was no significant difference among the essential oils with 1% concentration and control after 24, 48 and 72 h of treatment in contact and ingestion bioassays against workers of A. sexdens rubropilosa . However, Andiroba oil had less efficiency values in all concentrations been used. Therefore, the essential oils of mustard, cinnamon and clove have contact and ingestion effects on workers of A. sexdens rubropilosa and A. subterraneus molestans, and may be promising on the leaf-cutting ant control.

To investigate the feeding habits of the Kaloula borealis, the stomach contents of 52 out of 56 specimens collected around Daejung-up, Jeju Island in June 2011 were studied. The stomach contents were analyzed with the stomach flushing method. According to the results, the main preys of the Kaloula borealis were Diptera sp., Harpalidae, Formicidae and Drosophilidae. the Kaloula borealis of all sizes fed on small preys, while individuals with large SVL fed on big preys. By feeding on a large amount of food with a small number of activities, the individuals with large SVL is considered to enhance energy efficiency. In many cases, the Kaloula borealis fed on Diptera sp. or Drosophilidae, which are slow but active and capable of flying. As a result, the Kaloula borealis take the sit-and-wait form of preying rather than actively searching for food. The results of this research on feeding habits of the Kaloula borealis will provide valuable resources to protect the endangered Kaloula borealis experiencing a sharp decline in their population and to prepare plans for population preservation strategies for them.
