We investigated the moth diversity on an island of southern sea of Korea. We collected moths at three sites on the island of Bogildo, Wando-gun, Jeonnam using a 22-watt ultraviolet light trap from May to October, 2008, and identified a total of 272 species and 948 individuals in 13 families. Species of Noctuidae was the most abundant, with 107 species and 318 individuals, followed by Geometridae (62 species and 147 individuals) and Pyralidae (53 species and 269 individuals). The graph of the estimated species richness in Chao 1 (432.25$\pm$37.39) did not reach an asymptote, which suggests that more moth species could be identified on the island through further sampling. An arctiid moth, Miltochrista striata, was the most abundant species captured in this study. Monthly changes in moth species richness and abundance formed M-shaped curves, with peaks in early summer (June) and late summer (August). Cluster analysis of seven sites on three islands (Aphaedo Island, Sinan-gun, Oenarodo Island, Goheung-gun and Bogildo Island) divided the sites into two groups. Distances among sites and habitat types may play an important role in determining the similarities of moth faunas among sites.

We report three lepidopteran insect pests of non-astringent persimmon leaf for the first time from Korea; Hypocala deflorata (Noctuidae), Teliphasa elegans (Pyralidae), and Cuphodes diospyrosella (Gracillariidae). Larvae of these species were collected from an organic farming or abandoned persimmon orchard in Changwon and Jinju cities, Gyeongnam province, and reared for the identification in the laboratory. Some information, such as collection records, hosts, simple morphological characteristics, and ecology were introduced for each species.

Twenty four newly recorded and rarely known noctuid species from the Korean peninsula, which are preserved in domestic and foreign museums, are discussed in this article. Eleven species; Hypenodes curvilinea Sugi, Polydesma boarmoides (Guenee), Catocala bokhaica (Kononenko), Xanthomantis contaminata (Draudt), Craniophora harmandi (Poujade), Amphipyra acheron Draudt, Orthogonia tapaishana (Draudt), Chasminodes u.ssurica Kononenko, Oncocnemis campicola Lederer, Protomiselia bilinea (Hampson) and Xestia (Anomogyna) albonigra (Kononenko) are newly reported from the Korean peninsula. Among them, P. bilinea (Hampson), which has been known in Japan, is reported for the first time from the Continental Asia. The occurrence of Athetis pallidipennis Sugi, Pseudocosmia maculata Kononenko, Callopistria miracula Herz and Lacanobia dentata Kononenko are reconfirmed in Korea. Eudocyma salamina (Cramer) and Polydesma boarmoides Guenee are .considered to be tropical migrating species. A previously misidentified species, Hypenodes rectifascia Sugi is corrected as H. curvilinea Sugi.

Larvae of beet armyworm. Spodoptera exigua are extremely polyphagous. A total of 42 host p plants were identified in the field observations. Among them, vegetables were 13 species. upland crops 12 species, flowers species, and others including weeds 11 species. The damage by b beet armyworm was severe on Allium fistulosum in southern Chonnam. The percentage of hills d damaged was 86% in Jindo, Chonnam and 1.92% in Sesan. Chungnam. Nomuraea rileyi and nuclear polyhedrosis virus were identified on the larvae of Spodoptera exigua in Allium fistulosum fields and the percentage of parasitization was 4.3-9.7% and 3.2%, respectively. M Mortality of Spodoptera exigua larvae by Nomuraea rileyi in perilla was 13.4% in July 5, 28.9% in Aug. 7, and 18.5% in Sept. 10.

The methanol extracts from 30 species of oriental medicinal plants belonging to 24 families were tested for their lhicidal and antifeeding activit~es against diamondback moth (Plutello xylostella L) and tobacco cutworn (Spodoptera litura F.) by a leaf-dipping method at a concentration of 5, 000 ppm. The methanol extract from Copti chinensis only showed a potent larvicidal activity against P xylostello. Strong antifeeding activity against P. xylostello was observed from the extmds from Platycodon grandiflorurn, Codonopsis pilosula, Asomm sieboldii, Rhus chinensis and Uthospermum erythrorhizon And a potent antifeeding activity against S. liturn was obtained from Akebia quinata and Equlsetum hyemale extracts. A significant antifeeding activity against both species was obtained from R chinensis and C. chinensis extracts.

The Spatial distribution pattems of the oriental tobacco budworm (OTB), Helicoverpa assuita, eggs w were studied in red pepper and tobacco fields. With a plant as a sample Unit. Taylor's power law analyses indicated that om egg spatial patterns were clumped in red pepper fields (a=1.3914, b = 1.1648) and were unifom in tobacco fields (a = 1.6035, b = 0.6880). In red peppers om eggs w were found in leaves (76.2%), fruits (16.8%), stems (6.5%), and flowers (0.4%). The upper leaf surface ( (70.1 %) contained sianificantly more eggs than the lower surface (25.2%). In tobaccos most eggs were also found in leaves. However, the lower surface (66.3%) contained significantly more eggs t th

This study was conducted to investigate control effects against Spodoptera exigua Hubner in field using mating disruption dispensers of synthetic sex pheromone during 1993 and 1994. Denisities in egg and larva of Spodoptera exigua in field treated with the dispensers was 1.9% level of that without dispensers in welsh onion, 12.5% in red pepper and 4.4% in potato in 1993. Also 5.9% and 5.2% were counted from 10 ha and 20 ha of welsh onion field compared. Control value in Fields with dispensers were maintained at 80% level in 10 ha and 90% level in 20 ha until October.

We investigated the species richness of lepidopteran insects (excluding butterflies and microlepidoptera) of Mt. Seungdal-san, Muan-gun, Jeollannam-do, Korea, from 2003 to 2005 using two portable light traps. A total of species comprised 423 species belongs to 17 families were identified. The family Noctuidae with 209 species was dominant in the area followed by Geometridae with 132 species. Based on the number of individuals collected, Geometridae was the highest mostly due to an ennomine species (Alcis angulifera). Monthly fluctuations of moth species richness present an M-shaped curve with two high peaks at June and August. Comparisons of species diversity of yearly captures revealed that the diversity of 2003 was higher than that of 2004, but the diversities of between 2003 and 2005, and between 2004 and 2005 were no different.

The present study aimed to investigate the local moth fauna and population change during a year on Island Oenarodo (N34$^{\circ}$27'50", E127$^{\circ}$28'06", 74 m a. s. l.), Goheung-gun, Jeonnam. Moth collecting was carried out using a light trap from March to October, 2007. A total of 231 species and 562 individuals in 14 families were identified. Species of Noctuidae were the most abundant with 86 species and 163 individuals, followed by Geometridae (60 species and 147 individuals) and Pyralidae (39 species and 135 individuals), respectively. Monthly changes of moths species richness and abundance were M-shaped with two peaks at late Spring and late Summer. During the study, a geometrid, Menophra senilis, and a pyralid, Endotricha olivacealis were most abundant with 16 individuals. The estimated species richness using Chao 1 identified 646 species, suggesting that we need more extensive and long-term survey for the better understanding of the total moth fauna on the island.

The banana insect pest species and their damages were surveyed from 9 vinyl hoses of Cheju Island on August in 18. A total of 5 pest species wre found ; banana root weevil (BRW) Cosmopolites sordidus Germar (Curculionidae) a wireworm Melonotus sp. (Elateridae), a spider mite teranychid sp. (Tetranychidae), mulberry mealybud Pseudococcus comstocki (Kuwana)(Pseudococcidae), and common cutworm Spodoptera litura (Fabricius)(Noctuidae). Among them, the BRW which attacked the rhizome of banana plant was newly recorded from Korea. It is assumed that the weevil would be introduced from Japan, Philippine or SriLan-Ka wiht the banana seedlings imported during early 1980's.
