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.

In order to verify whether Zophobas atratus is an edible insect, the nutrients and harmful substances of Z. atratus larvae reared with an artificial diet (AD) and wheat bran (WB) were compared and analyzed. Based on dry weight, the crude protein content of Z. atratus larvae reared with an AD was 62.4%, 1.4 times higher than that of those reared with WB (45.2%). The crude fat content was 20.5% in the AD group, 2.3 times less than in the WB group (46.3%). The leucine content was 1.4 times higher in the AD group (4.2%) than in the WB group (3.0%). The glutamic acid content of nonessential amino acids was 1.3 times higher in the AD group (7.0%) than in the WB group (5.3%). The oleic acid content was 1.4 times higher in the WB group (37.0%) than in the AD group (26.7%). The potassium content was 1.1 times higher in the AD group (975.9 mg/100 g) than in the WB group (872.9 mg/100 g). According to the results of the toxic substances analysis, the lead and cadmium levels of the WB and AD groups were standard for edible insects. Pathogenic microorganisms, such as E. coli and salmonella, were not detected in either group. According to the results of the present analysis of nutrition and harmful substances, Z. atratus larvae raised on an AD are safe and contain various nutrients. Therefore, such larvae could be useful sources of food and feed.

The present study investigated the feasibility of using the ethanolic extract of Hermetia illucens larvae (HIE) as a whitening improvement material. In cell viability assays using B16F1 melanoma cells, no cytotoxicity was recorded up to 200 ㎍·mL^-1 of HIE. Moreover, while tyrosinase inhibitory activity increased, melanin content decreased in a dose-dependent manner, indicating that HIE likely inhibited tyrosine-induced intracellular melanin biosynthesis in B16F1 melanoma cells. Therefore, HIE is expected to serve as a potent whitening improvement material.

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.

We introduce a method for preserving yellow mealworm (Tenebrio molitor Linnaeus) larvae for an extended period and show that a high percentage of larvae can survive in good health under low-temperature storage conditions combined with specific diapause termination conditions. Our study revealed that we can regulate important development stages such as pupation, emergence, and larval duration by adjusting these termination conditions. When storing larvae aged 6-8 weeks for 140 days, the storage temperature can be varied based on our goals, giving us control over yellow mealworm production to meet specific demands. To produce adult beetles, storing larvae at 15 ℃ with wheat bran and ending diapause at 30 ℃ resulted in 90% pupation rate, with 60% becoming adults in 21 days. If our aim is larvae production, storing them at 10-12 ℃ with wheat bran and ending diapause at 25-30 ℃ allows the larvae to reach a suitable weight for processing. This straightforward approach ensures long-term storage of yellow mealworm larvae and provides a practical way to control their development, allowing efficient mass production tailored to market demands.

This study aimed to summarize the characteristics of visitor experience for different market segments based on insect experience orientation in order to develop Ptecticus tenebrifer (Diptera: Stratiomyidae [Walker]) experience programs using local resources in the insect industrial market. A total of 325 effective samples were collected, and the attributes of insect experience orientation were connected to education, emotion, society, and ego. The survey respondents were students and parents of school-age children. Cluster analysis showed that the respondents were classified into two or three groups that were all found to be high in the prediction validity and discriminant analysis. Based on this result, the respondents were properly subdivided into three clusters for final analysis. Those three groups were: the passive group, the moderate group, and the active-orientation group. As a group aiming for various insect experiences, the active-orientation group consisted of parents whose children range in age from either 5 to 9 or from 10 to 14. This group was willing to spend 7 ~ 8,000 won on each experience program, and they preferred emotional experience programs. The passive and moderate orientation groups were most interested in having an educational experience. In order to increase people's interest in experience programs, education-oriented programs should be developed and promotional marketing should be reinforced. The results and implications of this study may be useful for the development of insect experience programs that can meet various visitor experience orientations as basic data that can contribute to the vitalization of the 6th industrialization plan for the insect industry.
