  • Frankliniella occidentalis and Thrips palmi are economically important pests of cucumber. The chemicals used to control them can be effective; however, they should not be used frequently on cucumbers that are consumed raw. Banker plants were selected to increase the control efficiency of Orius laevigatus, a natural enemy that can replace the chemicals. The hatching rate, emergence rate, nymph developmental period, survival rate, and reproductive capacity (fecundity and oviposition period) of O. laevigatus for four plants (moss rose, basil, broad bean, and cucumber) were investigated. The density of O. laevigatus on two selected banker plants was investigated in a cucumber greenhouse. The hatching rate of O. laevigatus eggs was highest at 92% in moss rose; however, there was no significant difference in survival rates between moss rose and basil. The fecundity and oviposition period of O. laevigatus were better in moss rose than in basil, with no significant difference between them. The flowering period of basil was longer than that of moss rose, from April to September. Therefore, basil has potential value as a banker plant for O. laevigatus and is expected to increase the biological control effect of O. laevigatus.

  • Larvicidal activity of 34 plant essential oils were tested against the 4th instar larvae of Culex pipiens pallens. Among them, six oils (basil, fennel, caraway seed, lime, thyme red, and thyme white) showed more than 80% mortality at 100 mg $litre^{-1}$ concentration. GC and GC-MS analyses of the six essential oils and bioassay of their components revealed that anethole (a major component of fennel and basil oil) and (+)-limonene (a major component of caraway seed and lime oil) showed higher larvicidal activities than others. In addition to the above two components, ${\alpha}$-phellandrene, p-cymene, $\gamma$-terpinene, ${\beta}$-pinene, and thymol showed higher larvicidal activity than Bt product.

  • Purpose: This study was performed to evaluate the effects of sannamul or herb extract addition to a soybean oil-in-water emulsion during photooxidation in the presence of chlorophyll. Methods: The emulsion mainly consisted of purified soybean oil and citric acid buffer (pH 4.0) at a weight ratio of 4 to 6, with chlorophyll a addition at 6 mg/kg. Ethanol extract of daraesoon, samnamul, basil, or peppermint was selectively added to the emulsion at 400 mg/kg, and emulsions in glass serum bottles were oxidized at $5^{\circ}C$ under 2,600 lux light for 48 hours. Lipid oxidation of the emulsions was evaluated based on determination of headspace oxygen content, peroxide value, and p-anisidine value. Pigments and antioxidants were also monitored. Results: The emulsion with added samnamul extract with high contents of polyphenols and low chlorophyll content showed lower oxygen consumption, peroxide values, and p-anisidine values, whereas basil and peppermint extracts with high chlorophyll contents increased photooxidation. Chlorophylls were degraded during photooxidation of the emulsions, and the degradation rate was highest in the emulsion with added samnamul extract. Conclusion: The high antioxidant activity of samnamul extract in the photooxidation of soybean oil-in-water emulsion could be due to low chlorophyll content, high concentrations of polyphenol compounds in the extract, as well as rapid degradation of chlorophylls during oxidation.

  • Mentha spicata, Ocimum basilium L., and Rosemarinus officinalis L. were selected as subjects for the study, and analysis of rosmarinic acid contents by HPLC analysis and the fragrance components of each herb were compared by GC-MS analysis. It was prepared and cultivated in a herb farm located in Sacheonjin-ri, Gangneung-si in 2022 (Fig. 1) before flowering, collected in the summer, stored at minus 20℃, and dried 50 g each. The analysis was requested to the NICEM analysis room of Seoul National University to obtain the test results. Through the above study, HPLC showed that the content of rosmarinic acid was 555.53 mg/Kg, which was absolute, 27.12% in rosemary for 1,8-cineol in GC-MS, and 32.44% in linalool in sweet basil. For eugenol, 23.11% in sweet basil and 19.92% in rosemary were found in α-pinene. Through this study, it was verified that spearmint, sweet basil, and rosemary contain a large amount of major ingredients that act on concentration or brain activation.

  • Pesto were prepared with five different nuts including pine nut, sunflower seed, pumpkin seed, walnut and almond to examine the antioxidant properties(total polyphenols, total flavonoids, electron donating ability) and sensory test(attribute difference, acceptance). Pesto were measured based on color value, pH, viscosity, total cell numbers for 0, 5, 10, 15 and 20 days at $4^{\circ}C$. The higher total phenol and total flavonoid content of pesto added with various nuts was higher antioxidant capacity. Basil pesto added with sunflower seeds and walnuts were considered to be more functional more than pine nuts addition. The attribute difference test results was the color intensity, nut taste, bitter taste, coarseness, oily taste, thickness were evaluated significant difference kinds of nuts. Gloss, basil flavor, nuts flavor, basil taste were not evaluated significant difference in kind of nuts. The preference test results reveal that the appearance, taste, texture and overall preference level was the highest in PNP(pinenut pesto) and SSP(sunflower seed). L value, pH, decrease while a value, b value and viscosity increased as kind of nuts in during storage. Total cell number increased and then decreased a little at a certain point. When prepared pesto, SSP(sunflower seed) was the highest in antioxidant property, and change of color value, pH, viscosity, total cell number were the lowest. In addition to the use of pine nuts, sunflower seeds have been identified are possible.

  • We evaluated two herbal plants, basil (Ocimum basilicum) and lemon balm (Melissa officinalis), for their potential as repellent plants in the management of striped flea beetle (Phyllotreta striolata), in organic production of chinese cabbage. It was confirmed that striped flea beetle avoided these two herbal plants in olfactometer experiment. We conducted field experiment in which the suppressive effect of the two selected herbal plants and cruciferous crops preferred by striped flea beetle were evaluated through cultivating as inter crops and border crops, respectively. In inter-cropping experiment, unlike in vitro test, the density of striped flea beetle was low in basil- or mustard-intercropping cultivation plot, but high in lemon balm-intercropping cultivation plot. In border cropping experiment, the density of striped flea beetle on chinese cabbage in lemon balm or basil cultivation plot were approximately zero. As a result of this study, we think that border cropping of lemon balm or basil can be used to reduce preventively striped flea beetle of chinese cabbage under organic farming system.

  • This experiment was carried out to investigate watering with relation to growth, quality and yield of essential oil in sweet basil. The degree of water stress was taken as amount of watering. D1 was watered with 25mL for 2 weeks and 30mL from 4 to 5 weeks after planting in Wagner pot (1/20000a, ${\phi}24cm$). As this, 75mL and 90mL, 225mL and 270mL, and 675mL and 810mL were watered in D2, D3, and D4 treatment respectively. DFT was set up as water stress was not inflicted. The growth of basil in D3 and D4 was better than that of others, in which root activity was as much twice as that of D1. Essential oil of D1 was recorded the lowest content as 0.33%. The result of proline content, peroxidase activity, photosynthesis, stomatal conductance and stomatal resistance were proved D1 to be stressed. This treatment consequently increased the content of essential oil. In consideration of growth and essential oil content, D3 treatment was highest as 47.37mg in oil production per plant. Finally, D3 watered with 225mL for 2 weeks and 275mL from 4 to 5 weeks after planting could be selected on the purpose of both plant growth and essential oil production. Essential oil content of sweet basil was increased in response to water stress. For increase of essential oil yield, oil synthesis could be raised by giving water stress just before harvesting.

  • Bee propolis ethanolic extract with some plant essential oils was investigated for its antidermatophytic properties. The tested plant essential oils included jasmine, clove, lemon, Arabian jasmine, mint, rosa, olive and basil. The antidermatophytic activity has been compared to Naftifine-HCl and Clotrimazole used for dermatophyte treatment. Experimental model has been tested using sheep hoof plate for the in vitro tests to stimulate human nails. Mint, clove and basil with 4 mg/ml of bee propolis have a comparable efficacy to those of Naftifine-HCl and Clotrimazole. There is a great necessity for new effective low price and safe antidermatophyte agents to avoid recurrent infection. Propolis synergistic could be of great importance with essential oils of plants in dermatophyte therapy.
