This study was carried out to investigate the changing pattern of forest insect communities in 2013 after harvesting of forest in 2012, and provide a basic data for the method of efficient management for preservation of forest biodiversity. Five types of cutting method in pine tree forest were selected to compare the coleopteran insect communities at Hajang-myeon, Gangwon-do, Korea, in 2013. In this study, we investigated the effects of timber harvest with green-tree retention on coleopteran insects. They were sampled with Lindgren funnel traps for five experimental sites during July to October, 2013. A total of 1,112 individuals in 156 species of 40 families by Lindgren funnel traps. Also, the analysis of coleopteran insects community was performed. Although the difference of density is not prominent among the survey areas in the early stages, it was appeared a tendency to increase in density and abundance of insects in the experimented sites excluding the control areas. Among them, strip clear-cutting area showed a increase of density and abundance in this study.

Diversity and altitudinal distribution of the ground-beetles including Silphidae were investigated on Mt. Gabjangsan, Sangju city, Korea. Of the collected 10 species belonging to 3 families, Synuchus cycloderus was the most abundant species and S. nitidus was the relatively more abundant than the other species. The highest number collected was at alto 700 m. Simpson dominance index was 0.66 the highest at 700 malt., whereas, 0.47 at alto 800 m, was the lowest. The highest Simpson diversity index was noticed at alto 800 m (0.53). Also, seasonal indices of diversity and dominance of Simpson and Menhinick index were provided.

The burned pine forest may change into the grassland with bushes. However, it is likely that forest insects immigrated from the adjacent forest may be temporally abundant in the burned forest. This study was conducted to observe the immigration of insects for a year since forest fire. Beetle fauna in burned forest was compared with that in unburned forest in Goseong in Gwangwon province where the big fire was occurred and burned 3,762 ha of forest in 1996. The 381 individuals of 60 beetle species was collected from the burned forest, whereas the 370 individuals of 63 beetle species from the unburned forest. There was no difference in abundance and species richness of beetle fauna between burned forest and unburned forest. Most of abundant beetle species were collected from burned forest as well as unburned forest. Seasonal occurrence of the insects in burned forest were similar to those in unburned forest. These indicate active immigration of insects in burned forest in early season after fire. The beetles dwelling on vegetation were more actively immigrated into burned forest compared with those foraging in ground.

The present study was carried out to evaluate arthropod predators (Araneae, Carabidae, Staphylinidae, and Formicidae) as bioindicator for forest disturbance. We selected 12 study sites according to disturbance intensities caused by fire intensity and recovery methods at Goseong, Gangneung, and Samcheok in Gangwondo. Intensities of disturbance were characterized as follows: 0 (no fire), 1 (surface fire), 2 (crown fire), and 3 (crown fire followed by reforestation). Arthropod predators were captured using pitfall trap. Species richness and abundance of Araneae, Carabidae, Staphylinidae, and Formicidae were not different along disturbance intensities. However, species richness and abundance of grassland ants significantly increased in higher disturbance intensities. Abundance of grassland ants such as Formica japonica and Camponotus japonicas linearly decreased along litter depth. Furthermore, ant communities were clustered along disturbance intensities. In a one-time survey, ants may be most useful as bioindicator for forest disturbance among the four predator taxa, because ants actively forage for long seasons.

This research was carried out for revealing the co-relationships between insect-pollinators and the plant species of Labiatae and Umbelliferae, insects visiting in flower and the flowers in Korea, were studied from April 2010 to August 2012. The sum of flower visiting degrees in Labiatae are shown 21 in Hymenoptera, 16 in Lepidoptera, and the lowest 1 in Diptera and Coleoptera, respectively. The sum of flower visiting degrees in Umbelliferae are shown 27 in Diptera, 24 in Hymenoptera, 21 in Coleoptera, and 13 in Lepidoptera, respectively. 17 pollinator species visited the flower of Angelica gigas, next 15 pollinator species did the flower of Agastache rugosa, 13 pollinator species did the flower of Prunella vulgaris var. lilacina. 13 pollinator species foraged on the flower of Peucedanum terebinthaceum. and then 11 pollinator species on the flower of Angelica dahurica. Only 1 pollinator species visited the flower of Clinopodium chinense var. grandiflora and Isodon excisus. Pollinators of Coleoptera and Diptera visit more frequently to the flowers of Umbelliferae than those of Labiatae. Pollinators of Lepidoptera and Diptera visit more frequently white flower than purple one. This study found out that mutualistic relations between plants and insect pollinators in Korea.

Fourteen species of the genus Gonocephalum and one species of the genus Opatrum (Tenebrionidae, Opatrini) from Korea have been previously recorded. They are taxonomically reviewed based on many faunistic reports and research papers. We also examined many specimens including voucher materials of the previous studies. Among the recorded species, G. sabulosum is excluded because it was misidentified for the individual variation of Opatrum subaratum. We couldn’t find any Korean materials of four species (G. japanum, G. bilinearum, G. outreyi, G. malayanum), and used the materials determined from other countries. Key to 13 species of the genus Gonocephalum, illustrations of adults and male aedeagus are provided.

The study was carried out to investigate distribution and diversity of beetles with pitfall traps and beatings 3 times at Baegyang temple area of Naejangsan National park from July to September in 2010. A total of 333individuals belonging to 32 species from 13 families were captured beetles at Baegyang temple area of Naejangsan National park. The rate of captured individuals was 17.4% and 13.3% in Synuchus cycloderus and Synuchus nitidus, respectively. The total of two species was 30.7%. The number of individuals by altitude was the highest at 200m, and was order of 500m>400m>700m. A total of 333 individuals belong to 32 species from 13 families were captured at Baegyang temple area of Naejangsan National park. The number of captured individuals by monthly was 95 on July, 178 on August and 60 on September, respectively. Dominance index was the highest to Attelabidae and was the lowest to Rutelidae. Dominance index by monthly was the highest on July and was the lowest on September. Diversity index showed the highest to Rutelidae in family and on August in monthly.
