The genus Italochrysa Principi in Korea has been recorded with only one species, I. japonica (McLachlan) so far. Here we report that Italochrysa nigrovenosa Kuwayama is recognized for the first time in Korea. Specific description, a key based on diagnostic characters, and adult and genital images of the species are provided.

Micromus variegatus (Neuroptera: Hemerobiidae) is reported here as new to South Korea. In addition, three other hemerobiid species recorded only the collection data, Hemerobius harmandinus, Sympherobius tessellatus and S. domesticus are also reported with a brief description, images of the adult and wings, and its Korean common name. With four previously reported species in Korea, there are eight species of the family Hemerobiidae from Korea.

In the subfamily Drepanepteryginae of Hemerobiidae, Neuronema albostigma has been the only species known in Korea. Here we report that the genus Drepanepteryx Leach, 1815 and its species Drepanepteryx phalaenoides ($Linn{\acute{e}}$), 1758 are newly reported as a member of Drepanepteryginae in Korea. Together with a key for the species of Korean Drepanepteryginae, a brief description, COI barcoding sequence, and photos of adult and male genitalia for the species are provided.

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.

Constructed wetlands undergo biological and physical changes such as an increase in the proportion of arid plants due to the natural succession process after formation. It can adversely affect not only the purification function but also the habitat of species. As such, this study aims to identify environmental factors affecting biodiversity and propose management plans based on the monitoring results of physical environmental changes and the emergence of species in seven constructed wetlands selected based on the water depth and surrounding conditions among the lands purchased by the Nakdong River basin. We examined the environmental conditions and emergence of the Odonata, which is a wetland-dependent species, to predict the trend of changes in biodiversity and abundance. The results showed that the open water area decreased as the emergent plants spread to the deep water in 2015 compared to 2012 when they were initially restored to a depth of 0.2 to 1 m. While a total of 54 dragonfly species were observed, the habitat diversity, such as vegetation, water surface, and grassland, remained similar to the initial formation of the wetlands despite the expansion of the emergent plants. On the other hand, the number of Agrionidae species, which prefer areas with fewer aquatic plants, decreased between 2012 and 2015 due to the diminished water surface. The p-values of the differences in the number of species and population between wetlands by year were 2.568e-09 and 1.162e-08, respectively, indicating the statistically significant differences. The decrease in open water surface was found to have the greatest effect on the biodiversity and habitat density of dragonflies. The time-series survey of constructed wetlands confirmed that the spread of Phragmites communis, P. japonica, Typha orientalis, etc., caused a decrease in species diversity. It suggests that environmental management to maintain the open water surface area is necessary.

This studies was carried out to investigate the natural enemies of citrus red mite, pononychus citri and seasonal occurrence of its major beneficial insects in Yuzu groves (Chonnam province) from 1996 to 1998. Natural enemies against citrus red mite were 9 species including Oligota kashmirica benifica, 0. yasumatsui, Stethorus punctillum, Chrysopa pallens, Propylea japonica, Orius sauteri, Scolothrips takahashii, Amblyseius womersleyi and one unidentified species of thrips (Family: Phlaeothripidae). Among them, Oligota kashmirica benzficu and Stethorus punctillum were found to be dominant species. 0 . kushmirica henifica had 4-5 generations from middle May to middle November with peak in early September. S. punctillum had 3 generations from late May to late October with peak of late June to middle July. Population dynamics between predator ( 0 . kushmiricu benifica and S. punctillum) and prey (Panonychus citri) were quite well synchronized until September but predator density was decreased abruptly after October.
