Four feather mites, Dichobrephosceles actitidis(Canestrini, 1878)(Alloptidae), Limosilichus limosae Vasyukova and Mironov, 1986, L. numeni Vasyukova and Mironov, 1986 (Syringobiidae), and Pomeranzevia numenii (Canestrini, 1878) (Avenzoariidae), have been reported in Korea for the first time. Specimens of D. actitidis and L. limosae were obtained from the common sandpiper, Actitis hypoleucos (Linnaeus, 1758), and the black-tailed godwit, Limosa limosa (Linnaeus, 1758), respectively, while L. numeni and P. numenii were collected from the Eurasian whimbrel, Numenius phaeopus (Linnaeus, 1766). The genera Dichobrephosceles Peterson and Atyeo, 1968, Limosilichus Vasyukova and Mironov, 1986, and Pomeranzevia Dubinin, 1951 are also new records for the fauna of Korea. This paper provides morphological descriptions, illustrations, and partial sequences of mitochondrial cytochrome c oxidase subunit I(COI) for all the recorded species based on the specimens collected in Korea.

This study includes the taxanomy, description and a key to species of mites in the genus Asca from Korea. Specimens were collected from December 1993 to May 1996. As a result of this study, the following three species were identified. 1. Asca (Asca) aphidioides (Linne, 1758) 2. Asca (Asca) sculptrata Aoki, 1968 3. Asca (Asca) garmani Hurlbutt, 1963 These three species have not been described from Korea.

In this study, two mesostigmatic mites, Holostaspella crenulata Krantz, 1967 (Machrochelidae) and Lasioseius floridensis Berlese, 1916 (Blattisociidae) are recognized in Korea for the first time. The diagnoses, distributional data, drawing plates, and microscopic photographs are provided for each species.

The seasonal occurrence of insect pests in watermelon cultivated in greenhouses was surveyed in Gochang from 2006 to 2007 considering three seasonal types of culture: forcing culture, semi-forcing culture and retarding culture. Aphis gossypii, mites (Tetranychus urticae+T. kanzawai) and Palpita indica were the most serious pest species in watermelon greenhouse culture. A. gossypii and mites showed high density during the months of June and September in semi-forcing and retarding culture, respectively. Palpita indica was observed only in retarding culture. Leaf damage by Palpita indica was observed from the middle of August and peaked to 79.4% damage in the middle of September. Thrips and whiteflies were captured in high density by the yellow sticky trap in semi-forcing culture and retarding culture but these insects showed low population density in watermelon leaves.

In order to investigate the factors of the control mechanism of somitogenesis, early chick embryos (H-H stage $8{\sim}13$) were treated with heat shock, ${\alpha}$-amanitin and cycloheximide and morphological changes of somite were examined by light microscopy, transmission and scanning electron microscopy. In normal chick embryo, somites were formed from the somitomere which preexisted in segmental plate. Somites were wrapped with extracellular collagen fibrils and connected with neural tube, notochord and ectoderm. And then, somites were differentiated to sclerotome, dermatome and myotome by the interaction of nervous tissue. Abnormal somites were observed after formation of six or seven so mites in heat shock treated group. Amounts of collagen fibrils were obviously decreased in this group. In cycloheximide treated group, most so mites were smaller and neural tube formation was incomplete. Chromatins were condenced and formed several heterochromatins in the nucleus of somite cells. Lipid like cytoplasmic dense mass and lipid droplets were also observed. Segmentation of somites seemed to be normal progress in ${\alpha}$-amanitin treated group. Center of somite, however, hollowed in longitudinal sectioned samples. These results suggested that so mites were already existed in the segmental plate as the form of somitomere. Segmented somites were contacted with neural tube or notochord and the somites were tightly connected with each other by the extracellular collagen fibrils which were secreted from neuroepithelium and somite cells. Somites are thought to differentiate into sclerotome, dermatome and myotome by these interactions.
