The genus Parapammene Obraztsov, 1960 belonging to the subfamily Olethreutinae, family Tortricidae includes very small to small moths. The genus is characterized by the followings: forewing with median fascia and speculum, and without whitish stria below apex; tegumen of male genitalia being a broad band with the top emarginate laterally; seventh stenite of female genitalia, excavated in posterior edge (Horak, 2006). This genus comprising about 16 species in the world (Brown, 2005). In palaearctic region, there are about 10 known species, 5 species are recorded from Oriental region, and one species in Australian region (Komai, 1999). Comprehensive reviews of genus Parapammene Obraztsov have been given by Obraztsov (1960), Danilevsky and Kuznetzov (1968), and Razowski (1989) and Komai (1999). The following character states support the monophyly of Parapammene (Komai, 1999): 1) ductus bursae with a narrow, band-like sclerite; 2) seventh sternite of female a convex (not flat) plate; 3) S2 without anterolateral processes. In this study, the genus Parapammene Obraztsov are reported for the first time from Korea, with the first record of parapammene selectana (Christoph, 1881), P. petulantana (Kennel, 1901) and P. aurifascia Kuznetzov, 1981. Morphological characters of this genus are redescribed with illustrations of adults, male and female genitalia.

We prepared polycarbonate (PC)/poly(methyl methacrylate) (PMMA)/multiwall carbon nanotube (MWCNT) nanocomposites by co-rotating twin screw extruder at 533 K. Thermal analysis results indicate that the miscibility of PC and PMMA is enhanced by MWCNTs. Bead necklace-like morphology of PMMA-rich phase is observed in PC/PMMA/MWCNT nanocomposites with increasing PMMA weight fraction due to the bead necklace-like morphology. The tensile strength of PC/PMMA (75/25)/MWCNT (1 wt.%) nanocomposite is 3% higher than those of PC/PMMA (75/25) alloy. Suppression of die swell by MWCNT filler is observed in the melt flow of PC/PMMA/MWCNT nanocomposites during extrusion.

The genus Dichrorampha Guenée, 1845 belong to subfamily Olethreutinae, family Tortricidae described about 110 species in the Holarctic region (Brown, 2005). In Palaearctic region, there are about 90 species and about 20 species found in Nearctic region; 54 species are recorded from Europe (Razowski, 2003). Danilevesky and Kuznetsov (1968) established the subtribe Dichroramphae by the genus Dichrorampha Guenée. Razowski (1989), proposed the usage of Lipoptychina instead of Dichroramphae since the former name is older. Komai (1999) referred to the group as the Dichrorampha genus-group and added Pammenemima Diakonoff (= Titanotoca Diakonoff) to the group (Horak, 2006). Since Park (1983) reported two species of the genus for the first time from Korea, they are mainly studied by Park and Ahn (1986), Byun, Bae and Park (1998), Oh, Bae and Park (2001). Four species have been reported to present from the Korean peninsula. In this study, Dichrorampha gueneeana Obraztsov, 1953 is report for the first time from Korea. D. gueneeana Obraztsov, 1953 resembles with D. latiflavana Caradja, 1916 superficially, but the former is easily distinguished from the latter by following characters: dorsal patch of forewing color pale yellowish, and smaller than D. latiflavana Caradja, 1916; sclerite of colliculum slender; bent proximally and ductus bursae broader than D. latiflavana Caradja, 1916. Morphological characters of this species are redescribed with illustrations of wing venation and genitalia.

The genus pammene Hübner, [1825] is one of the genera related to Grapholita Treitschke, 1829, belonging to the tribe Grapholitini of the subfamily Olethreutinae (Bae & Park, 1998). The genus is mostly distributed in the Holarctic region, with about 100 species in the world. Danilevsky & Kuznetzov (1968) divided the genus into the two subgenera, Pammene and Eucelis. Komai (1999) discussed the phylogenetic position within the tribe. Since Park (1983) reported one species of the genus for the first time from Korea, they are mainly studied by Byun & Park (1993), Byun et al. (1998) and Bae & Park (1998). Up to date nine species have been reported from the Korea by Bae and park (1998). In this study, Pammene gallicolana Lienig & Zeller, 1846 is report for the first time from Korea. This species resembles with Pammene ignorata superficially, but P. gallicolana is easily distinguished from the latter by following characters: dorsal patch much larger, basal cavity much bigger, and apophysis posterior longer than P. ignorata, respectively. Morphological characters of this species are redescribed with illustrations of genitalia.

The genus Cydia Hübner is distributed in all the continents, with the tropical regions. However, It's rather insufficiently studied. In palaearctic, there are about 100 known species, less than half of this amount is Nearctic region; 49 species are recorded from Europe. The repartition areas of some species are wide, of some other small, however, they extend during the studies. The genus Laspeyresia Hübner, 1825, which was often used instead of Cydia until the late 1970s is help to be a junior homonym of Laspeyresia R.L,. 1817, an emendation of Laspeyria Germar, 1810 (Noctuidae). Comprehensive reviews of Cydia have been given by Heinrich (1926), Obraztsov (1959), Danilevsky and Kuznetzov (1968), and Razowski (1989). Komai (1999) discussed the phylogenetic position within the tribe (Horak, 2006). In the present study, the Korean species of genus Cydia are reviewed. A　total of 10 species are recogniged. Of them, Cydia danilevskyi (Kuznetzov, 1973) and Cydia indivisa (Dailevsky, 1963) are reported for the first time from Korea. Morphological characters of this genus are redescribed with illustrations of adults, wing venation, male and female genitalia. Distribution map, data matrix, cladistic analysis are provided.
