To investigate the degree of individuals' likability of insects, a survey was conducted with students and adults living in Korea. Overall, for insect-related questions, positive responses were higher than negative ones. Among the positive responses, the personal rearing of insects scored lower than others. The unconditional dislike of insects scored highest in the negative responses. A significant differences and correlations were found between males and females, students and adults, people experienced in insect-related events and those who were not. In particular, previous experience in insect-related events significantly influenced insect likability. Subjects preferred coleopteran and lepidopteran insects to others. However, this preference of insects differed by gender: Male participants preferred coleopteran insects to lepidopteran insects, while female participants preferred lepidopteran insects to coleopteran ones. No significant differences in the preference of insects were found by participants' job, residence, or experience in insect-related events. These findings suggest that gender is the most important factor to consider in selecting insects to be used as therapeutic tools in mental health care.

The purpose of this study is to organize research trends by analyzing healing studies using emotional insects, and to suggest future research directions. As a result, only six emotional insect species were used for healing purposes, and most of the age groups of the test subjects were elementary school students and the elderly. As for the type of research, field application of the healing program was dominant at 76.5%. Effectiveness verification was mainly conducted through questionnaires before and after participating in the healing program. In some cases, stress-related salivary hormones were used as indicators or clinical tests were conducted by medical staff. Based on the results of this analysis, future strategies such as finding new emotional insect species, developing various types of healing program models, and expanding and subdividing the target subjects were suggested to promote the growth of the healing industry using emotional insects in the future.

To investigate the degree of individuals' concept and awareness of insects, a survey study was conducted with students and adults living in Korea. The misconception rate for insects was about 50% for both students and adults, but it was lower for students and people who had experienced insect-related events than for adults and those who had not. The highest misconception rate was obtained in answer to a question about the basic structure of an insect. Most people had a high awareness of insects. Significant differences and correlations for the awareness of insects were found between students and adults, men and women, people who had experienced insect-related events and those who had not. The experience of an insect-related event most influenced awareness of insects. These results suggest that increasing people's interest in insects and utilizing insects in treatment situations may be beneficial for the field of mental healthcare.

Insects are gaining recognition as an alternative source of protein. As a result, more and more domestic farms have begun mass rearing of edible insects. In order to produce high quality insects, studies on the development of safe and nutritious feed sources are needed. Given the cost of rearing insects, agricultural and industrial by-products are good sources for feed. The efficient utilization of these by-products can help in reducing the cost of production and preventing environmental pollution. In the current study, Citrus unshiu peel (CP), soybean curd cake (SCC), soybean oil meal (SOM), and brewers dried grain (BDG) were investigated for their effects on larval growth and development of Protaetia brevitarsis. Interestingly, the feed with 10% SCC increased larval weight by 3.5 times. For the larval period, the group of 10% SCC was significantly shorter than the control. Furthermore, minerals such as Zn, Ca, K, Mg, Na, and P were recorded to be high in 10% SCC. A total of 17 amino acids were present in 10% SCC, of which tyrosine and arginine were predominant. The heavy metal contents were very small amounts or not detected in any of the investigated groups. These findings provided a scientific basis for the utilization of soybean curd cake as a nutritional feed source to promote larval growth and produce quality insects.

Industrial insect is defined as the insect utilized in industries that creates added value. Most of the industrial insects used in Korea are exotic species that are introduced through artificial means. Despite the rapid expansion of market for industrial insects, the system for risk assessment of industrial insects is not being adequately conducted. Although Korea carries out a risk assessment for the species designated as disease and insect pest by Animal and Plant Quarantine Agency, far too little consideration is being given to overall ecosystem, as the control system is covered in the Plant Quarantine Law. To solve this problem, we analyzed the Korean risk assessment system and looked at systems in other countries. The results show that it is essential for stakeholders to reach an agreement to set up fundamental directions for the system. Unless the integration system of taxonomical and ecological information is prepared, the ecological risk assessment should be conservative to protect ecosystems and should also follow the precautionary principle. It also requires cooperation among the ministries. In addition, the results indicated that a differentiation between risk assessment and screening is urgent. Several solutions such as setting up clear objectives in both assessment and screening stages, target species, steering organization and assessment criteria assessment systems from were proposed as practical institutional strategies. Among many foreign countries the assessment system from Ireland equally considers various factors such as economical, ecological safety and management aspects, It is also based on precautionary principle to fulfil its original purpose. It was suggested that the Ireland system would be the best reference that can be modified and applied into the Korean system by considering distinct characteristics of the industrial insects.

The most important factors in environment that influence the physiology of insects are temperature and humidity. Insects display a remarkable range of adaptations to changing environments and maintain their internal temperature (thermoregulation) and water content within tolerable limits, despite wide fluctuations in their surroundings. Adaptation is a complex and dynamic state that widely differs in species. Surviving under changing environment in insects depends on dispersal, habitat selection, habitat modification, relationship with ice and water, resistance to cold, diapause and developmental rate, sensitivity to environmental signals and syntheses of variety of cryoprotectant molecules. The mulberry silkworm (Bombyx mori) is very delicate and sensitive to environmental fluctuations and unable to survive naturally because of their domestication since ancient times. Thus, the adaptability to environmental conditions in the silkworm is quite different from those of wild insects. Temperature, humidity, air circulation, gases and photoperiod etc. shows a significant interaction in their effect on the physiology of silkworm depending upon the combination of factors and developmental stage affecting growth, development, productivity and quality of silk. An attempt has been made in this article to briefly discuss adaptation in insects with special emphasis on the role of environmental factors and their fluctuations and its significance in the physiology of mulberry silkworm, B. mori.

In accordance with Article 6 of the 「Insect Industry Promotion and Support Act」, the National Institute of Agricultural Sciences conducted a fact-finding investigation in the insect industry for related workers in 2020. Most commonly, insect industry workers were involved in production (98.5%), the male ratio was high (80.4%), while those in their 50s comprised 36.4% of the workers. As for the uses of industrial insects, 66.5% was for food and medicine, 12.7% for feed, and 20.7% as pets. The most commonly produced industrial insect species by use were the white-spotted flower chafer (69.6%), Protaetia brevitarsis seulensis (Kolbe), for food and medicine; crickets (31.2%) for feed; and the rhinoceros beetle (45.6%), Allomyrina dichotoma (Linnaeus), as pets. Powder was the most common product form at 68.5%, and live insects constituted 40.9%. Insect farms with an annual income accounted for 77.3%, of which 65.4% had annual sales of less than 20 million won. Market acquisition was rated by most insect industry workers (84.0%) as the primary challenge. In conclusion, although the number of people employed in the insect industry is increasing annually, the number of young insect farmers (20s to 40s) is decreasing. The production of industrial insects was limited to a few species, and more than half of insect farms have very low incomes. Furthermore, insect farms have the greatest difficulty in market acquisition, necessitating the development of utilization technology to promote the consumption of industrial insects.

Insects and their extract have been traditionally used as medicinal resources in Asia. Recently, Gryllus bimaculatus and the larva of Tenebrio molitor, Protaetia brevitarsis, and Allomyrina dichotoma were enlisted as general food ingredients by Korean Ministry of Food and Drug Safety. As the interest in these insects is growing, the detailed investigation is needed for the standardization of suitable and safe rearing techniques. This survey was conducted via personal interviews about edible insect rearing farms in Korea. The basic feed is fermented oak sawdust for P. brevitarsis and A. dichotoma and wheat bran for T. molitor. The various feed additives are blended with each farm's own recipes. The overall growth condition, including sawdust fermentation method, feeding period, and rearing density, varies among the investigated farms. It seems that weight of last instar larva was correlated with the rearing density and duration of the larval period. The heavy metal contents were analyzed after 48 hour starvation and they were very small amount or not detected in investigated insects. We believe that the present data will contribute to develop and standardize the safe rearing techniques of edible insects in Korea.

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.
