The red imported fire ant, Solenopsis invicta Buren, 1972 (Hymenoptera: Formicidae: Myrmicinae) was discovered in Busan sea port, Korea. Only one colony was found and then removed rapidly by Animal and Plant Quarantine Agency.

To search for habitat characteristics of myrmecochory Melampyrum species, diaspores and related ant species, habitat characteristics, collecting fruits and diaspores of three Melampyrum species, cafeteria experiments, and the related ant species were studied from May 2012 to November 2014. The habitat of Melampyrum species was south-facing open forest edge with slightly acidic soil and relatively shallow soiil layers. Major plants coexisting with Melampyrum species were four woody species including Quercus mongolica and four herbaceous species including Carex siderosticta. These Plants might be host plants of the Melampyrum species. The shape of the diaspore was an oval seed attached to the white cap on one side. Significant differences is proved between three plant species in weight of diaspores, seeds and and elaiosome ratios. Mean values of diaspores weight showed 10.6mg, 8.0mg and 7.2mg in M. setaceum var. nakaianum, M. roseum var. ovalifolium and M. roseum, respectively. The heaviest elaiosome is M. roseum var. ovalifolium with 1.2mg, M. setaceum var. nakaianum has 1.0mg and the lightest elaiosome is M. roseum with 0.8mg. Major ant species frequently transporting the diaspores of Melampyrum species are Myrmicinae four species; Myrmica kotokui, M. excelsa, Myrmecina nipponica and Aphaenogaster japonica. Further studies on Melampyrum species, hemiparasite annual myrmecochorous plant, and related ant species should be needed.

Vertical distribution of ants were studied in Jiri mountain by collecting 15 times at 42 sites for 3 years since 1984. 31 species of 16 genera in 3 subfamilies were collected during the survey. The following 6 species, i.e., Formica japonica, F. lemani, Lasius niger, L. alienus, Pheidole fervida and Myrmica ruginodis were dorminant one, but 9 species such as Leptothorax congruus, Pheidole nodus, Aphanogaster japonica, Jollenhovia emeryi, Camponotus tokioensis, Polyrhachis lamellidens, Phagiolepsis mandjurica, myrmica yessensis and M. sulcinodis were rare species. The ant of Jiri mountain consisted of 16 species in Formicinae, 13 species in Myrmicinae and 2 species in Ponerinae. Ponerinae was distbriuted as far as 1,800m, but Myrmicinae and Formicinae to 1,915m. Only 8 species-Myrmica ruginosis, Myrmica sp., M. yessensis, M. sulcinodis, Leptothorax acevorum, Formica japonica, F. lemani and Camponotus japonicus-were collected at the submit of Jiri mountain, Cheonwangbong. The vertical distribution of C. atrox was ranged from 800m to 1,800m.

In Vollenhovia emeryi (Hymenoptera: Myrmicinae), the queen and the male are known to be clonally reproduced. Its colonies can be classified into the two morphs with the wing length of the queen caste. The morph with normal wings is called the long-winged and the other the short-winged that is brachypterous. Even though the two morphs are considered a species, investigation on the species status of the two morphs was suggested with natural separation in nature and the distinctive wing morphology. It has yet to be determined whether the clonally reproduced queen caste is haploid or diploid. Our data clearly show that the two morphs are the same species and the queen caste is diploid on the basis of the genome size data comparison.

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.
