We investigated moth communities in Samcheok, Korea, to elucidate the influence of the East Coast Fire in 2000. Moths were collected with UV light traps 4 times a year from 2006 to 2009 at 3 sites: Unburned area (Site 1), Surface fire area (Site 2), and Crown fire area (Site 3) sites, respectively. A total of 3,804 individuals belonging to 727 species from 30 families were captured at the 3 study 1,727 individuals of 505 species (27 families) at Site 1, 1,193 individuals of 353 species (24 families) at Site 2, and 885 individuals of 340 species (25 families) at Site 3. Species richness and individuals of Noctuidae, Pyralidae, Geometridae, and Tortricidae were the highest at all 3 sites. All of species richness, individuals, and species diversity (H') were the highest in Site 1 for 4 years. The index of similarity (α-Index) was higher between Site 2 and 3 in 2006, while higher between Site 1 and 2 in 2009. Moths were grouped into 16 categories by hosts of the larval stage. Individuals of moths of herbaceous feeding habit continuously decreased at Site 3, but proportion of individuals of tree feeding habits continuously increased. The present results showed that moth communities was relatively recovered according to vegetation change after forest fire and regeneration of moth communities in surface fire area was more faster than in crown fire area.

The purpose of this study is to investigate the effects of the natural river conservation work and to find remedies for them, targeting Jangsu-cheon with high frequency of use by citizens among the rivers in Incheon Metroplitan City, Korea; for this, this study conducted investigations and analyses of Jangsu-cheon completed in December, 2008. As a result of investigating 3 spots for the water system of Jangsu-cheon over a total of 3 years (2009, 2010, 2014), it was found that benthic macro-invertebrates of a total of 3 phyla, 5 classes, 11 orders, 26 families, 56 species, and 980 specimens were distributed there. When they were analyzed by year, 18 families and 30 species in 2009, right after the natural river conservation work, and 22 families and 37 species in 2010, 2 years after the work, were found, with 7 species increasing in number; after that, as a result of the investigation in 2014, 22 families and 38 species were found, which tells the river has entered the stabilization stage since the recovery in 2010.Therefore, this study could identify: the water environment of the river was improved due to the natural river conservation work for Jangsu-cheon; in addition, Jangsu-cheon showed good ecological environment due to the continuous maintenance of the good wetlands in Incheon Grand Park in the upper area of the river; and the natural river conservation work of Jangsu-cheon created positive effects.

The tribe Eucosmini is the second largest tribe of Olethreutinae with more than 1,000 species in over 125 genera, distributed mostly in the Holarctic region, and over half of the known species occur in the Nearctic region (Horak and Brown, 1991b). Eucosmini can be separated from other tribes by a combination of the following characters proposed by Kuznetsov and Stekolnikov (1984): 1) one‐branched protuberance of the valve; 2) gnathos and uncus is very weakened or reduced. In Vietnam, in the period 1977–1978 and 1997–1998, National Institute of Plant Protection (NIPP) recorded only seven Tortricidae species. Recently, Kuznetzov (2001) recorded four species in the Southern part of Vietnam: Eucosmogastra aeolantha (Meyrick, 1914), Noduliferola pleurogramma (Clarke, 1976), N. atriplaga (Clarke, 1976), N. phaeostropha (Clarke, 1976). Razowski recorded 14 species of 10 genera of Eucosmini (2009). In this study, we are briefly reviewed of tribe Eucosmini in the Northern part of Vietnam. As the result of this study, a total of 19 Eucosmini species of 13 genera are recognized. Of them, 17 species are reported for the first time from Vietnam such as: Coenobiodes acceptana Kuznetzov, 1973; Epiblema foenella (Linnaeus, 1785); Lepteucosma ceriodes (Meyrick, 1909), etc. The materials identification based on the collection of University of Incheon, which has collected from 2004–2009 in the Northern part of Vietnam by Vietnamese and Korean entomologist.
