Research confirms that healthful benefits accrued when people connect with nature and insect by viewing and interacting with them. Insect rearing is easy, relatively inexpensive, and can breed small space. This study aimed to investigate the physiological effects of animal assisted activity using insect(Oriental garden cricket) with diets and a rearing manual. The group of insect activity whose ages ranged from 65 to 82 years old that attending a community center in Daegu, Korea, were enrolled in the study between April and May 2014. The collected data was analyzed using qualitative analysis. Qualitative study is utilized to explore mental models, and their linguistic, affective, cognitive, social and cultural significance. The result showed that people-insect interactions promote well being of the elders, and the important aspect of insect activity aids in improvements in their social, emotional and cognitive functioning which were enhancing life satisfaction, reducing loneliness and increasing activities of daily life.

In India, forest based insect enterprises has never been linked up with any forest management activity, either as a forest conservation strategy or to reduce the poverty in forested area. This investigation indicated that when forest dependent people are associated with forest insect industry (FII) like forest sericulture, lac culture or apiculture; this income generating activity links livelihood with forest conservation, and generates a viable model of collaborative forest management (CFM). In this model different stakeholders work together as a coherent entity for unified goal of managing the forest for well-being of the poor people in fringe areas. Article summaries and evaluates the prospect of India specific forest insect industry, and discusses how and to what extent integration of FII could be a viable livelihood component in CFM to conserve the forest and insect biodiversity. We analysed a case study on forestbased rearing of tropical tasar silkworm rearing in Central India from CFM perspective. Arguments in this communication are intended to provide forest managers and policy-makers with necessary input to consider location specific FII in CFM mode to provide a continuous source of small income to forest dependent people to ensure long lasting success of their forest management endeavours.

Insect fauna in adjacent areas of Demilitarized Zone (DMZ) in Korea was surveyed seasonally in $2001{\sim}2003$. The survey area was divided into 3 regions (eastern mountain, middle inland, and western coastal regions) in accordance with administrative districts and topography. Sampling methods such as sweeping, sieving, beating, brushing and suction were used depending on the environmental and military conditions. Total 361 genera and 437 species of 116 families belonging to 14 orders were identified. Among these, 46 species were new to insect fauna of DMZ areas. Species richness was the highest in the eastern mountain region. Numbers of habitat-common and -specific species were 96 (22%) and 195 (47.2%), respectively. The insect species community similarity was highest (0.64) between eastern mountain region and western coastal region. Insect orders showing high species richness were Coleoptera (38.9%), Lepidoptera (19.2%), Orthoptera (9.4%), and Hemiptera (9.2%). These results will be useful information for study of history on the change of insect fauna and future conservation in DMZ areas.

The composition of the Martes flavigula diet has been extensively studied, but little is known about its insect component. This study characterized the insect diet and insect nest materials in the feces of M. flavigula. A total of 952 fecal samples were collected in Jirisan National Park from January 2009 to November 2011, and 1379 species or taxonomic groups were identified. M. flavigula fed on insects (8.7%) and bee wax (5.0%), which comprised 2.9% and 4.4% of the dry weight of M. flavigula feces, respectively. A total of 12 insect species belonging to 8 families in 3 orders were identified. The most frequently found insects were Hymenoptera (frequency of occurrence, FO, 89.1), including Vespa simillima simillima (FO, 37.3) and Vespula koreensis koreensis (FO, 20.0). The Vespidae constituted the majority of the insect diet in autumn when the diversity of marten's prey was strongly reduced, probably because the numbers of social insects were sufficient for M. flavigula. In addition, the data suggest that M. flavigula attacks the nests of social wasps in late autumn when males do not have a venomous sting and new queens are less aggressive than workers. Bee wax appeared in all seasons and the highest rate was from spring to early summer. However, the remains of honeybees were not found in feces; thus, M. flavigula presumably eats honey but not honeybees.

Lipoprotein-associated phospholipase $A_2\;(Lp-PLA_2)$ is a potential biomarker of coronary heart disease and plays an important proinflammatory role in the progression of atherosclerosis. Also acyl-CoA: cholesterol acyltransferase (ACAT) and oxidized low-density lipoprotein (LDL) playa key role in atherosclerosis, respectively. And so, the inhibitory activities of the methanol extracts of 42 insect resources were examined on $Lp-PLA_2$, ACAT, and LDL oxidation for screening of anti-atherogenic substances. Among them, the methanol extracts of Eurydema rugosa significantly inhibited all of upper three activities. Several kinds of tested insects having high inhibitory effect with the methanol extracts were extracted with n-hexane, ethyl acetate, and acetone, and their inhibitory activities were tested.

The study aims to identify the moderating effects of involvement on satisfaction, recommendation, and revisit intention in insect exhibition. Tourism motivation and involvement are crucial factors influencing visitors satisfaction. Particularly, the study aim to examine the moderating effects on tourism involvement between tourism motivation and visitors' satisfaction. Data were collected from 346 usable questionnaires among visitors of the pet insect competition. Results of a factor analysis yielded three dimensions of tourism motivation which are insect experience/learning, recreation/escape, and social and friendship. Hierarchical regression analysis indicates that insect experience/learning motivation and recreation/escape motivation influence visitors' satisfaction, Results also show that visitors' involvement has moderating effects on satisfaction. It was suggested that visitors' motivation and involvement be considered in insect exhibition and events.

The reasons for selecting insects as future food are high growth and feed conversion rates, reproduce quickly, low environmental footprint, valuable source of nutrients, and source of a various undeveloped functional materials. Since 2014, Tenebrio molitor larva, Protaetia brevitarsis larva, Allomyrina dichotoma larva, and Gryllus bimaculatus were registered as new food in Korea because it has been scientifically proven that they are not harmful to eat and nutritious. Therefore they can be legally produced and sold as food. Accordingly, there are 7 species of edible insects including grasshopper, silkworm pupa, and Baekgangjam in Korea. To improve aversion to edible insects, using their powder, chop, and gravy hidden their morphology, we developed more than 100 different kinds of recipes for general food menu, held several times tasting events to be familiar with edible insect food, and published cookbooks. Moreover, we developed more than 50 kinds of recipes for patients. To eat the insect food more and more people, we have been analyzed various function of insects. If health food based on the results of functional analysis is developed, edible insect's value will be raised. If various insect foods are developed and consumed by people, edible insect market will grow up more than 100 billion won in 2020.

A total of 20 mulberry varieties preserved in Korea were typed for eight polymorphic microsatellite loci. We obtained 6 to 15 alleles per locus with an average value of 10.6, per-locus observed heterozygosity ranging from 0.35 to 1.00, and per-locus polymorphic information content (PIC) ranging from 0.61 to 0.87, indicating that most loci are highly variable. Phylogenetic analysis using the eight microsatellite loci was sufficiently suitable for classifying 20 mulberry varieties preserved in Korea. A total of 160 variety-specific apomorphic alleles were obtained from eight loci discriminated 20 mulberry varieties. These variety-specific alleles from this analysis are expected to be useful for the discrimination of other mulberry varieties. Furthermore, a substantial number of homozygote loci, represented by 60 among 180 alleles in eight loci were found. These results collectively suggest that these microsatellite locus primers are potentially crucial molecular markers for the eventual classification of mulberry varieties that are preserved as hundreds in Korea.

Functional foods, introduced in the early 1980s, offer health benefits beyond basic nutrition and are increasingly demanded due to growing consumer awareness of diet-health relationships. This review explores insect-based functional foods, highlighting their nutritional benefits, health implications, and applications. Edible insects, such as crickets, mealworms, and locusts, are rich in protein, healthy fats, vitamins, and minerals, making them a promising solution for food security and sustainability. Insect-based foods contribute to weight management, cardiovascular health, anti-inflammatory properties, gut health, and potential anti-cancer benefits. Despite most insects being low in calcium and potassium, they are high in phosphorus and, to a lesser extent, magnesium. Active components like royal jelly, bee pollen, and extracts from Tenebrio molitor and Periplaneta americana L. have shown potential in osteoporosis prevention by improving bone density and reducing bone resorption. Silk sericin-based functional foods also exhibit preventive and therapeutic effects against bone loss. However, challenges such as regulatory barriers, food safety concerns, consumer acceptance, potential allergenicity, and the need for standardization and quality control must be addressed. This review underscores the potential of insect-based functional foods in enhancing health and well-being, particularly for osteoporosis prevention, and highlights the need for further research and regulatory harmonization to facilitate their adoption.
