This study examined the consumers' perception of edible insect foods and carried out importance-satisfaction research on the choice attributes of edible insect foods. Through this, the potential of food materials as future food resources was evaluated and foundational data was provided to devise marketing strategies required to develop products made from edible insect foods. According to the results, females had more information on edible insect foods than males (p<0.05), and males gained higher points in trying new foods (p<0.001), overall satisfaction (p<0.001), and purchase intention (p<0.01) than females. Both importance (p<0.05) and satisfaction (p<0.001) about the mean of the choice attributes of edible insects were higher in males than females. The sustenance area showed high importance and high satisfaction, including taste, smell, freshness, sanitation, safety, and shelf-life. Accordingly, to understand edible insect foods properly, it is important to deliver information constantly and publicize them aggressively. In addition, it is necessary to develop various kinds of food made from edible insect foods and functional foods utilizing their nutritive value.

Among edible insects, black soldier fly (Hermetia illucens), yellow mealworm (Tenebrio molitor), and common housefly (Musca domestica) have been considered as an alternative protein source for pigs. Because they are easy to breed and grow in the organic wastes, and they have well-balanced nutritional value as a protein source for pigs. The black soldier fly larvae and mealworm could replace the fish meal in the diets for weaned pigs without adverse effects on growth performance and nutrient digestibility. Black soldier fly could also be included in the finishing pig's diet without any negative effects on the growth performance and pork quality of the market pigs. Insect products showed a greater standardized ileal digestibility value of amino acids than conventional animal proteins in growing pigs. Due to the limited amount of insect products used for pig feeding study, most previous pig studies have been conducted in weaned pigs. Thus, further study is needed about the optimal inclusion level of insect products in every phase diet from weaned pigs to sows. The use of insect products in swine diets has some challenges in terms of cost, supply, and safety. Lastly, intrinsic differences among insect species, processing method, and feeding phase should be taken into consideration for the use of insect products in the swine diets.

Insects are among the most important abiotic and biotic constraints to rice production. National rice research programs are in various stages in the development and implementation of integrated pest management (IPM) stratagies for rice insect control. Among the various control tactics, insect resistant cultivars are sought as the major tactic in rice IPM. Through the activities of interdisciplinary teams of scientists significant progress has been made in the development and release of insect resistant cultivars to farmers. Because of its compatibility with other control tactics insect resistance has proven to fit well into the IPM approach to rice insect control agents and minimize the need for insecticide applications. The development of biotypes which overcome the resistance in rice plants has been a significant constraint in the breeding of rice for resistance to insects. Most notable examples in Asia are the green leafhopper, Nephotettix virescens, brown planthopper, Nilaparvata lygens and the Asian rice gall midge, Orseolia oryzae. The current breeding stratege is to develop rice cultivars with durable resistance on which virulent biotypes cannot adapt. In spite of the significant progress made in the breeding of insect resistant cultivars there are still numerous important rice insect species for which host plant resistance as a control tactic has not been fully utilized. Advances in biotechnology provide promise of solving some of the problems that have limited the use of host plant resistance as a major tactic in the integrated management of rice insect pests.

This study was done to develop environmental risk assessments and a biosafety guide for insect-resistant genetically modified rice at a LMO (Living Modified Organism) isolation field. In the LMO quarantine area of Kyungpook National University, the species diversities and population densities of non-target insects found on insect-resistant genetically modified rice (Bt-9) resistant to Cnaphalocrocis medinalis and on non-GM rices (Dongjin and Ilmi) were investigated. The Bt-9 event was therefore evaluated under field conditions to detect possible impacts on the above ground insects and spiders. The study compared transgenic rice and two non-GM reference rices, Ilmi and Dongjin, at Gunwi in Southern Korea in 2016. Each rice was grown on three $18m^2$ plots with a randomized block design. A total of 4,243 individuals from 43 families and 9 orders were collected from the LMO isolation field. In the three types of rice fields, a total of 1,467 individuals from the insect-resistant genetically modified rice (Bt-9), 1,423 individuals from the Ilmi, and 1,353 individuals from the Dongjin were collected, respectively. There was no difference between the population densities of the non-target insect pests, natural enemies and other insects on the insect-resistant genetically modified rice (Bt-9) and non-GM rices. These results provide the diversity and population density of non-target insects for an environment risk assessment survey on insect-resistant genetically modified rice and could be used as a guideline to make a biosafety assessment method for genetically modified crops.

The current market size of insect industry in Korea is estimated at 300 million dollars and more than 500 local farms are related to many insect industry. One of the strong candidates for insect industry is Korean horn beetle, Allomyrina dichotoma. Early this year, we reported a viral disease extremely fatal to A. dichotoma larvae. While we were proceeding a nationwide investigation of this disease, it was informed that similar disease symptom has been occurred occasionally during past over 10 years. The symptom can be easily confused with early stage of bacterial infection or physiological damage such as low temperature and high humidity. A peroral infection with the purified virus to healthy larvae produced a result that only 21% of larvae survived and became pupae. Although some of the survived adult beetle was deformational, many of them had no abnormal appearance and even succeeded in mating. Later, these beetles were examined if they were carrying the virus, and all except one were confirmed as live virus carrier. This implies that these beetles may fly out and spread the disease to the nature. We found the evidence for this possibility by collecting a few wild A. dichotoma larvae which were virus infected, near two local farms rearing A. dichotoma larvae. So far, transovarial transmission of this virus to the eggs, or horizontal transmission to other commercially reared insects is not known yet.

Insect-healing program is designed for farm use, and this study attempted to scientifically investigate its healing effect based on application methods. The insects used in the program are Trypoxylus dichotomus, Papilio xuthus, and Bombyx mori. Insect-healing program was conducted on 61 adults of over 50 years old and at two different farms for 12 weeks. Stress, anxiety, insomnia, and cognitive function were measured through pre- and post-surveys. Result of the analysis showed that cognitive function changed positively in direct experienced group (those that encountered live insects) and indirect experience group (those that encountered insects only through photos and videos). However, psychological variables such as stress and anxiety decreased and sleep time increased significantly only in the direct experienced group. These results demonstrate that an agro-healing program that involve the use of insect must include activities such as raising and taking care of live insect to achieve positive psychological healing effects.

The purpose of this study is to investigate effects of natural incense on the preservation of paper- and textile-based remains and the kinds and applications of natural anti-insect incense by reviewing relevant literatures of the ancient times. There are few ancient literatures of incense published in Korea. The researcher deducted how incense was used in this nation through reviewing verses contained in ancient literatures and medical books. In contrast, the kinds and applications of anti-insect incense used in China, where incense culture prospered, were investigated here through reviewing technical books about incense published during the Song(宋) and Ming(明) periods, $\ll$Incense record(香譜)$\gg$, $\ll$Chen's Incense record(陳氏香譜)$\gg$ and $\ll$Incense record(香乘)$\gg$. There were several methods of keeping clothes better from insects. In relation, how to use anti-insect incense varied in accordance with main materials of clothes, paper, textile, leather and others. Cymbopogon dstans(芸香), Brassica rapu var and Incarvillea sinensis(角蒿) are anti-insect incense which were used for paper. Anti-insect incense for textiles is classified into single and mixed incenses depending on whether only one kind of incense was used or more than seven kinds of the substance. Acori rhizoma(菖蒲), Capsella bursa-pastoris(薺菜花), Lactuca sativa L., Erigeron canadensis(莽草), Stemona japonica(百部) and Moschus sifanicus(麝香) are single anti-insect incense which were used for textile. While, the latter was called. ‘Yi Xiang(衣香)’ is mixed anti-insect incense which was used for textile. Artemisia asiatica(艾葉) and Zanthoxylum schinifolium(花椒) are anti-insect incense which were used for leather. Angelica dahurica(芳香) and Bamboo are anti-insect incense which were used for others. There were three main methods of using incense to prevent insects, that is, diffusing incense's strong scent and ingredients, exposing to smokes from burnt incense and washing with incense-boiled water. Diffusing incenses had a strong scent and antibiotic ingredients, which were put between books or clothes or into a storage box without being processed. If necessary, however, they were processed into rough powders that were in turn used singly, or otherwise mixed for a stronger scent and better insect elimination. Exposing to smokes from burnt incense was done as follows. A clothes was put on 'Long(籠)' underneath which there was a boiling water. The clothes was humidified by the water and then exposed to smokes from burnt incense. 'Long(籠)' had been long used since it was manufactured in the QinHan(秦漢) period for the first time. A local literature, $\ll$Koryo TuGing(高麗圖經)$\gg$ shows that in the Koryo(高麗) period, BoShaLu(博山爐) were used as a means of exposing clothes to smokes to prevent moths, similarly to China. Washing clothes with incense-boiled water was more effective in removing lots of worms and germs from clothes, but leaving the scent and ingredients of the used incense and maintaining the effect of anti-insect.

Insects have many excellent features and functions in their small bodies, such as hexapod walking, flapping flight, vision systems, sensory hairs, etc, and those characteristics can be thought as good models for many types of robots. Insects also will be good models far micro-machines because of its size. Insect behavior consists of simple reflex acts and programmed behavior, Some robots were made in order to clarify the emergent mechanism of insect behavior, Through some experiments it would be found that even if insect behavior consists of some simple action patterns, it looks intelligent through interactions its sensors and actuators with its complex environment. In the near futures small robots inspired by insects will be used in many fields of our life. I hope that insect-model based robots will play an active part in many fields and that they will make us happy.
