  • A Cordyceps species was found with a Beauveria anamorph state on larval insect cadavers on Obong mountains in Gangwon Provinces, Republic of Korea. Cultures from discharged ascospores formed an anamorph identifiable as Beauveria bassiana. This teleomorph-anamorph connection was also confirmed by the in vitro production of fertile ascomata from conidial cultures with morphology like that of field-collected specimen. This is the first report of in vitro production of a teleomorph for any Beauveria species. The Cordyceps species has been conspecified as Cordyceps bassiana, a species described from China with B. bassiana anamorph.

  • Phytophagous insects of Monocotyledoneae were surveyed from May to October in 1991. Each p province was divided into 9 localities by $\boxplus$-shape for the collection. Seventeen weed species b belonging to 17 genera were collected, namely, 14 Graminales weed species of 14 genera, 1 s species of Farinales weed, and 1 species of Liliales weed. Phytophagous insects representing 5 orders, 13 families, 27 genera, and 36 species comprised the insect fauna on Monocotyledoneae w weeds. Five species were not identified out of 36 insect species. Grasshoppers, hemipteran, s scarab beetles, and leaf beetles were frequently collected. Lema concinnipennis was a potential biological agent on Commelina communis, and Oulema dilutipes was first collected from Setaria u viridis. Commelina communis in golf course was severely damaged by Adoretus tenuimacu/atus c chafer but this insect was also an important insect pest of turfgrass and trees.

  • 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.

  • Insect cell culture system has been demonstrated the effective means of producing medical and agricultural products. Furthermore, Fetal bovine serum (FBS) is in wide use in insect cell culture. Silkworm hemolymph was tested to develop as a substitute for FBS and was effective in insect cell growth. Hemolymph is oxidized and darkens visibly during the collection from silkworms due to the activity of tyrosinase in it. Toxic quinones are produced by the oxidation and consequently inhibit the cell growth. Heat treatment can be used to prevent the oxidation; however, the oxidation may occur during the collection of hemolymph before it is heat-treated. Hemolymphs collected from 257 different strains of silkworms were examined to select the slowly oxidized hemolymphs. Hemolymphs collected from mutant strains such as $Y_4$, TBO and $wE^b$ showed relatively slow color changes. Oxidation rates of the hemolymphs were measured by the absorbance change using a spectrophotometer. The absorbance of mutant hemolymph reached the saturation value at $20^{\circ}C$ in each 330 min ($Y_4$), 360 min (TBO) and 450 min ($wE^b$) min, whereas the total oxidation time of the wild-type (Baekokjam) hemolymph at the same temperature was 120 min. The cell growth in the medium supplemented with mutant species hemolmph was more effective that in the medium supplemented with Baekokjam species hemolymph.

  • Terrestrial insect fauna was surveyed in the Junam wetland area, which consists of the Junam, Dongpan, and Sannam wetlands, by visual counting and pictures. A sweep net collection was conducted from May to October 2010. A neighburing artificial lotus wetland was also surveyed for comparison. A total of 5,730 insects were surveyed, representing 268 species in 85 families and 12 orders. Sixty-three species of coleopterans were surveyed, followed by 60 species of Lepidoptera, and 37 species of Hemiptera. Coleopteran individuals were 25.9% of the total insect numbers surveyed, comprising most abundant group. This was followed by Odonata, Lepidoptera, and Orthoptera at 22.3%, 15.4%, and 12.7%, respectively. In total, 197 species were surveyed in the Dongpan wetland, 175 in the Junam wetland, and 154 species in the Sannam wetlands. However, only 86 species were surveyed in the artificial lotus wetland. Galerucella nipponensis in Coleoptera, Crocothemis servilia mariannae in Odonata, and Polygonia c-aureum in Lepidoptera were the most abundant in all four wetlands. Community analyses showed that the dominance index was highest in the artificial lotus wetland at 0.25 and lowest in Junam wetland at 0.08. Diversity indices were relatively high in all wetlands at 4.48, 4.44, 4.28, and 3.87 in Junam, Dongpan, Sannam, and the artificial lotus wetland, respectively. The insect fauna similarity index was highest in the Junam and Dongpan wetlands at 0.96. The lotus wetland showed the lowest similarity of the three wetlands with values of 0.45-0.53.

  • In this study, we report three insect pest species of non-astringent persimmon, Pleuroptya chlorophanta, Acria ceramitis, and Choristoneura longicellana, for the first time from Korea. Larvae of these species were collected from an organic farming persimmon orchard in Changwon city, Gyeongnam province, and reared in the laboratory to be identified in 2012. Some information, such as collection records, hosts, simple morphological characteristics, and ecology were introduced for each species.

  • The traditional oviposition ground for indoor breeding of Luciola lateralis is moss. This study was conducted to find the most suitable alternative oviposition ground that can maintain or increase the oviposition rate of L. lateralis while addressing the problems of larva collection time and larva loss that occur when moss is used. As alternative candidate oviposition ground comprising six colors of non-woven fabric and felt were used to measure the fecundity variation rate of L. lateralis with respect to the color and material of the oviposition ground. In addition, measure the fecundity variation rate of L. lateralis in moss, a traditional oviposition ground, was also measured and investigated for comparison. The investigation showed that the average number of eggs in the non-woven fabric group was higher than that in the felt group. The yellow non-woven fabric had an average number of eggs that was more than 100 times higher than of moss used as a traditional oviposition ground. In the space where the six color non-woven fabric were together, L. lateralis concentrated its oviposition on yellow. These results showed that yellow non-woven fabric can be sufficiently used for efficient indoor mass breeding of L. lateralis while addressing problems caused by moss, a traditional oviposition ground.

  • A total of 45 scale insects belonging to 29 genera of five families were recognized on 15 kind of flowering plants on the basis of specimens collected in 2003 and specimens deposited in the Insect Collection of NIAST in Korea. Three species were recognized on Korean forsythia, four on chrysanthemum, 15 on common camellia, seven on kobus magnolia, three on rose of sharon, one on Indian lilac, six on rose, seven on rhododendrons, two on bamboo palm, three on benjamin tree, 12 on evergreen euonymus, five on Japanese yew, two on corn plant, six on orchids and two on cacti. Pulvinaria floccifera (Westwood) and Pseudaonidia paeoniae (Cockerell) on common camellia and Pulvinaria citricolar Kuwana on rose of sharon are reported for the first time from the Korean Peninsula.

  • This study aims to examine the effect of healing program using insect. For the insect resources, the program uses 3 species of emotional insects. The subjects were a total of 29, the elderly with mild dementia and adults with developmental disabilities in the facility. The activities are 9 programs in total and each program takes 2 hours once a week. For data collection, we measured a blood pressure, stress level using autonomic nervous system activity, and scale of happiness, depression and insomnia by a survey. The datas were collected every week before and after the program. As a result of paired-sample t-test analysis, the participants of the agro-healing program using insects had positive effects as follows: reducing a depression, relieving a symptom of insomnia and stabilizing a blood pressure. Through the results of this study, it was possible to confirm the positive effects of the agro-healing program using insects. If farms lead agro-healing program using insects on their own, it could be expected to contribute to improve the quality of life through agriculture as well as to improve the farms' income.
