  • The community of xylophagous beetles belonging to Cerambycidae, Curculionidae and Scolytinae in Korean white pine, Pinus koraiensis Siebold & Zuccarini, forests was surveyed using Malaise traps in 2007. A total of 1,615 xylophagous beetles were collected, including 184 cerambycids from 15 species, 185 curculionids from 17 species, and 1,246 scolytid beetles from 6 species, of which the dominant species was the ambrosia beetle Xyleborus mutilatus Blandford. Ranked by order of population size, the wood-boring and bark beetle community in Korean white pine showed high dominance by one species of Scolytinae, suggesting the community had low biological diversity. Thinning in Korean white pine forests influenced on the abundance of bark and ambrosia beetles, whose populations in particular stands increased 1 year after thinning, and then decreased the following year.

  • Wood products are sometimes infested with cossonid weevils. A cossonid weevil, Hexarthrum brevicorne Wollaston has been found on wood boards used for printing books in the Jeonju Confucian temple and school (2004), a wood cabinet in the Museum of Milyang (2007), a wood wardrobe in the Museum of Seoul (2008) and on wood boards used for printing Buddhist scriptures in the temple of Suncheon (2008). Wood utensils for living in the Museum of Seoul were found to be infested with another cossonid weevil, Rhyncolus sculpturatus (Waltl) in 2008. To protect the cultural property from insect pests in the field of conservation science, more comprehensive insect pest management (IPM) programs are required.

  • This study has been monthly carried out to investigate the community structure and seasonal variations of Coleoptera from April to September, 2004 in Mt. Yeonyeop area, Gangwon-do, Korea. A total of 3053 individuals belonging to 358 species in 49 families have been collected in the studied area by light trap, pitfall trap and sweeping methods. The abundant families, based on the number of species, were Carabidae (50 species), Chrysomelidae (40 species) and Curculionidae (40 species). The number of species were highest at site 4, located in low altitude and contained stream. The number of individuals were highest at site 2, because many beetles were attracted by pitfall traps. The total number of species and individuals was highest in July. Nicrophorus (Nicrophorus) quadripunctatus (13.00%) was a dominant species and Synuchus (Synuchus) cycloderus (7.17%) was sub dominant species. Especially Damaster mirabilissimus mirabilissimus, a protected species by government, was collected in May.

  • The genus Blacus Nees is cosmopolitan genus of the subfamily Blacinae. The members of genus Blacus endoparasites of colepterous larvae: Staphylinidae, Nitidulidae, Cryptophagidae, Scolytidae, Anobiidae, Curculionidae and Melyridae. Previously, 13 Korean species of the genus have been investigated by several researchers. In this study, eight species of the genus Blacus are reported for the first time from Korea: Blacus apaches Achterberg, B. chabarovi Belokobylskij, B. compressus Belokobylskij, B. fischeri Haeselbarth, B. interstitialis Ruthe, B. mamillanus Ruthe, B. robustus Haeselbarth, and B. ussuriensis Belokobylskij. Diagnosis and host records are given for each species.

  • Lariophagus distinguendus,an ectoparasitoid of rice weevil, laid its eggs exclusively on the third and fourth larvae, with the preference for the fourth larva. The sex ratio of the pa¬rasitoid can be regulated by the female parasitoid on the basis of the host size available at the time of oviposition.

  • The hazelnut leaf holer (Anoplus roboris Sufr,, Coleoptera: Curculionidae) is a devastating pest of hazelnut and oak trees. It causes approximately 20-30% economic damage to hazelnut production per year in Turkey. In the present study, in order to fond a more effective and safe biological control agent against A. roboris, we investigated the bacterial flora of the hazelnut leave holer, and tested them for insecticidal effects on it. According to morphological, physiological and biochemical tests bacterial flora were identified as Bacillus circulans (Ar1), Bacillus polymyxa (Ar2), Enterobacter sp. (Ar3) and Bacillus sphaelicus (Ar4). Insecticidal effects of bacterial isolates were performed on adult A. roboris. The highest insecticidal effect determined was 67% by B. sphaericus within eight days. The insecticidal effects of the other isolates (Ar1, Ar2 and Ar3) were determined as 33%, 47% and 47% within the same period, respectively.

  • To compare the occurrence of Coleoptera by different sampling methods such as light trap, pitfall trap and sweeping, we collected samples every month from April to September,2004 in the Mt. Yeonyeop, Gangwon-do, Korea. According to the sampling methods, the species composition, abundance and dry weight were completely different. We collected 151 species in 35 families (690 individuals) by sweeping method, 148 species in 30 families (689 individuals) by light trap, and 112 species in 18 families (1,674 individuals) by pitfall trap, respectively. The dry weight in collected sample was about 181.46 g in pitfall trap,39.85 g in light trap, and 10.89 g in sweeping method, respectively. Relatively high flight and small-sized beetles such as Coccinellidae, Nitidulidae, Scarabaeidae were collected in light trap. The species diversity was high in July. Unlike the samples collected in light trap, the pitfall trap samples were big-sized saprophagous or carnivorous beetles such as Carabidae, Silphidae, Staphylinidae. The pitfall trap showed relatively the higher number of individual and lower species diversity compared to other methods. The major samples collected by sweeping method were small-sized carnivorous or herbivorous beetles such as Chrysomelidae, Curculionidae, Coccinellidae. The peak of species diversity occurred in May. The similarity was calculated with the Jaccard's index over the light trap-pitfall trap was 0.07, light trap-sweeping was 0.10, and pitfall trap-sweeping was 0.01. Consequently, similarity of sampling methods was relatively low. In conclusion, efficiency of the each sampling methods significantly differed in the species composition of Coleoptera. This study emphasize the necessity of using three sampling methods in the area of diversity research.
