This research was conducted to investigate the competition for survival between the two cricket species: Gryllus bimaculatus (GB) and Teleogryllus emma (TE). The test insects for this research were bred in the greenhouse of the Ecological Entomology Lab, College of Agriculture and Biosciences, Kyungpook National University, Korea. The feeding environment was $28^{\circ}C$ to $30^{\circ}C$, Long-Day condition (16L : 8D) and Relative Humidity: 50%~60%. The changes of the individual number in two species (TE, GB) were checked every day. This research had three experimental conditions which the ratios of individuals (TE : GB) were set at 1 : 2, 1 : 1 and 2 : 1. The survival rate of GB was net better than that of TE in the result of this study. However, due to the absence of the diapauses period in the egg stage, GB would dominate over TE in the field condition. The appropriate legal measure against GB is recommended.

생쥐 비장세포에 대한 아열대산 귀뚜라미(Gryllus bimaculatus)와 왕귀뚜라미 (Teleogryllus emma)로부터 3종 추출물(Al, A2, Bl)의 면역활성능을 조사하였다. 3종의 추출물 모두 normal spleen cell에 대하여 독성을 나타내지 않았다. Al과 A2는 세포의 proliferation을 증가시키는 경향을 나타내었으며, 1000ug/m1의 고농도에서는 약 10-20%의 증가를 보였다. Bl의 경우는 약간의 감소경향을 나타내었으며, T cell의 mitogen인 Con A에 대한 mitogenic response는 두드러진 활성을 나타내지 않았다. (중략)

Egg-forming and preservation methods for the indoor-rearing system of the emma field cricket, Teleogryllus emma, were investigated. The oviposition preference experiment on different mats, soil(natural oviposition mat) and $oasis^{\circledR}$(artificial oviposition mat), showed that T. emma preferred to oviposit on the $oasis^{\circledR}$. On the other hand, $oasis^{\circledR}$ had more inactive number of eggs laid per female and hatchability than another. However, the number of eggs laid per female and hatchability within 50 days after emergence were better than soil. The experiment on the hatching of the eggs showed that eggs could be stocked at $10^{\circ}C$ for 40 days with 14 day pre-period after laying, representing $62.1\%$ hatchability, when considering generation shortening. On the other hand, When it had been kept in cold storage for 90 days at $7.5^{\circ}C$ with 14 day pre-period after laying it, appeared to be the most suitable for long period-storage method by hatchability $65.1\%$.

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.

Web structure of spiders is a foraging strategy as well as an investment to get prey. In order to make a good foraging decision spiders should change its foraging strategy in the basis of sensory information provided by potential prey species. We conducted experiments to demonstrate whether a wasp spider, Argiope bruennichi modifies its web-building behavior after experiencing sensory information emitted by a cricket species, Teleogryllus emma. To know how the web structures would be modified, we quantified web characteristics after providing sensory information of the cricket and compared to the control group. Web construction decreased in the course of the experiment in both, control group(without stimulus) and experimental group(with stimuli). The results did not show remarkable differences between two groups. However, on the first day after providing sensory information of the cricket, the web-building behavior of A. bruennichi decreased only in 3.7% of the experimental group individuals against 11.8% of the control group individuals. The number of the stabilimentum constructions decreased overall in both groups. On the first day the decreasing proportion was doubled in the control group(14.7%), comparing to the experimental group(7.4%). The individuals did not lower its web height and did not extend its web area according to sensory information of the prey.

The suppression of neuroinflammatory responses in microglial cells, well known as the main immune cells in the central nervous system (CNS), are considered a key target for improving the progression of neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and Huntington's disease. Teleogryllus emma is widely consumed around the world for its broad-spectrum therapeutic effect. In a previous work, we performed transcriptome analysis on T. emma in order to obtain the diversity and activity of its antimicrobial peptides (AMPs). AMPs are found in a variety of species, from microorganisms to mammals. They have received much attention as candidates oftherapeutic drugs for the treatment of inflammation-associated diseases. In this study, we investigated the anti-neuroinflammatory effect of Teleogryllusine (VKWKRLNNNKVLQKIYFVKI-NH₂) derived from T. emma on lipopolysaccharide (LPS) induced BV-2 microglia cells. Teleogryllusine significantly inhibited nitric oxide (NO) production without cytotoxicity, and reducing pro-inflammatory enzymes expression such as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). In addition, Telegryllusine also inhibited the expression of pro-inflammatory cytokines such as interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) through down-regulation of the mitogen-activated protein kinases (MAPKs) and nuclear factor kappa B (NF-κB) signaling pathway. These results suggest that T. emma-derived Teleogryllusine could be a good source of functional substances that prevent neuroinflammation and neurodegenerative diseases.
