  • In order to study the insect-insect interaction of the insect community associated with Rumex obtusifolius. this experiment was designed in such a way that the feeding of one insect could indirectly affect the subsequent insect species through the changes in host plant (plant mediated insect-insect interaction ). Philaenus spumarius and Gastrophysa viridula were selected for the experiment. To investigate the effect of P. spumarius feeding on the ecology of G. viridula, first, statistical analyses were carried out. As results. no significant difference between Control and Experimental was found in the development patterns (Repeated Measures ANOVA, F=0.744, p=0.667) and survivorships (F=0.373. p=0.990). As the results from this experiment show, there was no effect on the ecology of G. viridula due to the previous feeding by P. spumarius on R. obtusifolius leaves.

  • 본 논문에서는 곤충 종의 외관구조인 머리, 몸통, 날개, 다리에 대한 관찰자의 일반적이고 수평적인 관찰특성에 따라 자유롭게 곤충 종을 관찰함으로써 관찰 곤충 검색엔진에서의 사용자 만족도 제고와 보다 효율적인 관찰학습의 방법을 제안한다. 자연생태 환경에서 초보 학습자의 효율적인 관찰검색과 효과적 학습을 위해서는 생물학적 분류체계가 아닌 곤충 종의 외관구조 즉, 외부 신체구조의 모양과 특성 중심의 곤충관찰 기반의 검색(Insect Search by Observation based on Insect Appearance: ISOIA)이 필요하다. 그러므로 본 연구에서는 곤충의 외관구조인 머리, 몸통, 날개, 다리에 대한 관찰자의 일반적인 관찰방법에 따른ISOIA 검색방식을 제안하고, 기존의 ISBC와 ISOBC 검색체계에 대한 사용 만족도를 비교 분석하여 본 논문에서 제안하는 ISOIA 검색 방안이 우수함을 보이고자 한다.

  • Insects are the most successful organisms on earth in terms of their diversity and adaptability. Insect biotechnology using this insect resource is an emerging area for future biotechnology with various applications. Insect resources have long been used to make food and/or functional food, feed, cosmetics as well as medicine and industrial ingredients. Recently, one of the most well-known industrial material from insect is spider silk that could be commercialize in near future. The insect cell lines have been used to express recombinant proteins that were difficult to be functional expression. For public purpose, while, the insect could be good amenity source and plant farming, so leisure resource. Only the interdisciplinary research will guarantee the successful story for insect biotechnology. And biochemical engineers should used insect as a bioresource for new products with applications in medicine, agriculture, and industrial biotechnology in near future. This review will cover state-of-the art of this field and the research and application areas of insect biotechnology and the possible role of biochemical engineer for the development of the future biotechnology using this bioresource.

  • This study aimed to investigate the psychological effect of a healing agricultural program using insect resources and to confirm the persistence of the healing effect. The applied insect was silkworm Bombyx mori (Linnaeus) and 28 adolescents from local children's centers were used as the subjects. The healing agricultural program was applied at the centers for 4 weeks, and stress was measured using salivary α-amylase levels and a survey on life satisfaction, happiness, and insect preference. The results indicated that stress levels decreased, and life satisfaction and insect preference increased after participating in the the healing agricultural program. Furthermore, it was confirmed that this healing effect continued until 4 weeks after the end of the program.

  • Many insects such as mosquitoes cause life-threatening diseases such as malaria, yellow fever and West Nile virus. Malaria alone infects 500 million people annually and causes 1-3 million death per year. Volatile insect repellents, which are detected through the sense of smell, have long been used to protect humans against insect pests. Antifeed-ants are non-volatile aversive compounds that are detected through the sense of taste and prevent insects from feeding on plants. The molecular targets and signaling path-ways required for sensing insect repellents and antifeedants are poorly understood. Transient Receptor Potential (TRP) Ca2+-permeable cation channels exist in organisms ranging from C. elegans to D. melanogaster and Homo sapiens. Drosophila has 13 family members, which mainly function in sensory physiology such as vision, thermotaxis and chemotaxis. G protein-coupled receptors (GPCRs) initiate olfactory signaling cascades in mammals and in nematodes C.elegans. However, the mechanisms of G protein signaling cascades in insect chemosensation are controversial. In this review, I will discuss the putative roles of G protein-coupled receptors (GPCRs) and Transient Receptor Potential (TRP) channels as targets for insect repellents.

  • In recent years, many research revealed plant-insect interactions are becoming unstable because of climate change, human activities and grazing effect. In this work, it is aimed to disclose that how climate of two different years is influencing on insect community at certain locality in Mongolia. The data on the insect community are collected, covering full flowering season from June to August in 2014 and 2015. In order to include all species of insects in Udleg Station, data was collected in three different sites. One of them was around edge of forest, another one was in ungrazed area or inside the fence that has been kept for more than 9 years and last one was in grazed area. Weather was a perceptible difference during two year's study. This climate differences significantly influenced on the insect community. In 2014, overall 305 insect species were recorded, in which 124 insect species in order of Diptera, 44 in Lepidoptera, 33 in Coleoptera, 31 in Hemiptera, and 73 in Hymenoptera were determined. But in 2015, these number of species noticeably decreased, and total 150 insect species were recorded, in which 58 in Diptera, 26 in Lepidoptera, 13 in Coleoptera, 12 in Hemiptera, and 41 in Hymenoptera were determined.

  • Fruit bagging is a traditional way to produce high-quality fruit and to prevent damage from insects and diseases. Growing pears by non-bagging is concerned about the damage from insect, it can be controlled by installing a insect net facility. Wind load should be considered to design the insect net facility because it has the risk of collapse due to the strong wind. So we carried out wind tunnel test for measurement of drag force, where the insect net with porosity about 65% is selected as an experimental subject. As a result of the test, drag force was measured to be 244.14 N when insect net area and wind speed are $1m^2$ and 22.7 m/s respectively. And, drag coefficients for the insect net were found to be about 0.55~0.57, which may be used as the preliminary data to design the insect net facilities at the orchard.
