  • In this study, the community structures of arbuscular mycorrhizal fungi (AMF) in rhizospheres of Camellia japonica and neighboring woody plants in Wando, Korea were investigated. Rhizospheres of C. japonica and other woody plants were dominated by the same species, Acaulospora mellea, but Shannon's index, species richness and total spore numbers of the AMF communities were higher in non-C. japonica than in neighboring plants. Regardless of host plant species, the frequency of A. mellea was significantly high comparing with other AMF species. The community similarity of AMF within C. japonica was significantly higher than between C. japonica and neighboring plants or neighboring plants (p<0.005). Results showed that AM fungal communities in rhizospheres of C. japonica have unique community structure and are different from that of neighboring host plants, suggesting that community structure of AMF could be influenced by host plant species.

  • A revised checklist of host plants for 181 species belonging to 103 genera in six subfamilies of Cerambycidae (Coleoptera: Chrysomeloidea) in Korea is provided on the basis of the results of field surveys and literature review. A total of 14 new cerambycid-host associations are confirmed and the Manchurian striped maple, Acer tegmentosum Maxim. (Aceraceae), is listed as a new host of the Asian longhorn beetle, Anoplophora glabripennis (Motschulsky). The names of more than 170 host plants species belonging to 107 genera in 44 families are compiled. Among them, four families (Ulmaceae, Pinaceae, Fagaceae and Betulaceae) are confirmed as the main host families (more than 23%) of most of the cerambycid species. All invalid scientific names and Korean names of plants and cerambycids in the previous literature are corrected in the present paper.

  • Host plants and host preference of brown chafer, Adoretus tenuimaculatus Waterhouse (Coleoptera: Scarabaeidae) were investigated in fields and laboratory. 66 kinds of plants in 25 fanlilies were recorded as host during the field survey and 14 kinds in 5 families were verified to be eaten by artificial plant supply. Thus, host plants of A. tertuimaculatus were 186 kinds in 42 families in total including 136 kinds of plants in 32 families from literatures. 50 plants in 19 families were newly recorded as host of A. tenuimaculatus in this study. A. tenuimaculatus was the most frequently visited to J14glans sinensis and Caztanea crenata was the highest damaged plant. C. crenata, Robinia pseudoacasia, Malus sieboldii, J. sinensis, Quercus mongolica, and Q. aliena were considerably highly preferered host plant. However, A. tenuimaculatus never visited to Diospyros lotus, J. nigra, Fraxinus mandshurica, F. rhynchophylla, Pyracantha angustqolia, Paulownia coreana, and Celtis sinensis. Even the same host plant of A. tenuimaculatus. preference was different according to observed place and damage level was also different depending on observed place and time.

  • Surveys were conducted to study nationwide distribution and identify habitats and host plants of Cuscuta pentagona Engelm. as a parasite. The major habitat types were arable land near agricultural waterways (54.3%), open field near roadside (41.3%) and artificial grassland (4.3%). The investigated host plants of Cuscuta pentagona consist of total 130 taxa: 10 varieties, 1 subspecies, 119 species, 95 genera, and 37 families. Among them, 30 taxa were alien plants. As for the useful plants, there were 59 taxa of edible ones (45.4%), 54 taxa of medicinal ones (41.5%), 13 taxa of ornamental ones (10%), 13 taxa of industrial ones (10%), and 9 taxa of pasture ones (6.9%). On arable land, it caused damage particularly to the growth of agricultural crops such as Oryza sativa L. (Rice) and fruits such as Malus pumila Mill. (Apple) etc. Its growth and distribution may cause economic loss for crops because of the close location of the arable land.

  • The damage of citrus fruits caused by Scirtothrips dorsalis Hood has being increased in Jeju, Korea. The seasonal abundance of S. dorsalis and its injury symptoms in citrus orchards have been studied since the endemic outbreak in Jeju, but studies for the occurrence pattern of S. dorsalis in citrus orchards influenced by adjacent primary hosts have not been fully conducted yet. We selected kiwi- and mango-citrus adjacent orchards to study the migration pattern of S. dorsalis toward to citrus orchards. Yellow-colored sticky traps were used for monitoring the seasonal abundance of S. dorsalis and their migration pattern in two orchards. In citrus orchards, also, we placed sticky traps at 0, 5, 10, 15 and 20 m apart from the border of kiwi orchard, and 0, 7 and 20 m apart from the border of mango orchard. The seasonal occurrence pattern of S. dorsalis caught on sticky traps were similar between two adjacent orchards. However, the abundances in kiwi or mango orchard was much higher than those of citrus. Also, it was found that densities, distribution and damage of S. dorsalis in citrus orchards depend highly on the distance from the border of kiwi and mango orchards. This result suggested that the primary hosts such as kiwi and mango plants influence the occurrence of S. dorsalis in adjacent citrus orchards. And this information may provide a basic direction for establishing the management strategy of S. dorsalis in citrus orchards.

  • Regional distribution of mistletoe (Viscum album var.coloratum) and its habitual environments were investigated in order to obtain the basal data on the artificial propagation to cope with its increasing consume for medicine. Mistletoes inhabited throughout the overall region of the South Korea investigated. They were parasitic mainly to the Quercus spp. including Q. serrata and rarely to the Castanea crenata var. dulcis, Prunus serrulata var. spontanea, Alnus japonica, and Pyrus pyrifolia, etc. Mistletoes were not observed on the conifers such as Pinus densiflora and Pinus koraiensis and some deciduous broad-leaved trees species such as Zelkova serrata, Diospyros kaki, Acer mono, Acer palmatum, and Morus alba. Their habitats were located from zero to 1,200 m above sea level nevertheless the direction or slope of the mountains, suggesting that artificial propagation can be carried out nation widely to the well-grown parasite tree species. Parasitic specificity related to the physical and chemical characteristic of the epidermal tissues will be studied further.

  • Corythucha marmorata (Uhler) belonging to the family Tingidae (Hemiptera) has been reported in Korea. In 2013, surveys were conducted to study its morphological characteristics, geographical distribution, and host plants. The adult is brown white and 2.77-3.28 mm in length, and the mature nymph is yellowish brown. Heavily infested trees appear yellowish white because they are fed on by the nymphs on the under surface of host plants. C. marmorata were found between early June and late October, and their numbers peaked in early July to late August. In 2013, the occurrence of C. marmorata was confirmed in 27 cities and counties nationwide, and 8 families and 24 species of host plants were identified. C. marmorata feeds on the following major host plants: Conyza canadensis, Aster pilosus, Helianthus annuus, Artemisia princeps, Rudbeckia bicolor, and Solanum melongena.

  • All viruses have few genes relative to their hosts. Viruses, thus, utilize many host factors for efficient viral replication in host cell. Virus-host interactions are crucial determinations of host range, replication, and pathology. Host factors participate in most steps of positive-strand RNA virus infection, including entry, viral gene expression, virion assembly, and release. Recent data show that host factors play important roles in assembling the viral RNA replication complex, selecting and recruiting viral RNA replication templates, activating the viral complex for RNA synthesis, and the other steps. These virus-host interactions may contribute to the host specificity and/or pathology. Positive-strand RNA viruses encompass over two-thirds of all virus genera and include numerous pathogens. This review focuses on the importance of host factors involved in positive strand plant RNA virus genome replication.

  • We investigated the diversity of lepidopteran larvae and their food plants in a 0.1 ha plot at Mt. Jirisan National Park, South Korea. The plant species in the plot were identified, and the lepidopteran larvae that fed on each plant in the plot were collected. Thus, we collected 141 plants of 16 species that belonged to 14 families and 159 lepidopteran larvae of 70 species that belonged to 11 families. Oak (Quercus serrata) was found to be the most favored plant species. Among the 11 lepidopteran families, the species richness and evenness of two families, Geometridae and Noctuidae, were the highest. On the basis of this study, we could assume the interaction between food plants and caterpillars in a temperate forest. Furthermore, we could estimate the species diversity of lepidopteran caterpillars in this temperate forest.
