  • Most oriental medicinal plants in domestic markets have been imported, but these medicines are being easily exposed to many insect pests because of the poorness of storage facilities. This study was carried out to identify stored products insect pests occurring in 158 storage medicinal plants belonging to 134 genera of 67 families. No insect pests were not observed in 44 medicinal plants including Artemisia argyi Levl. et Vant., Cassia sieboldii Presl., and Juniperus chinensis L. Most commonly observed stored products insect pests in the surveyed medicinal plants were the order of as follows; Ahasverus advena(Waltl) 12.3%, Lasioderma serricorne F. 11.5%, Oryzaephilus surinamensis L. 10.3%, Tribolium castaneum (Herbst) 9.4%, Stegobium paniceum L. 8.4%, and Plodia interpunctella(Hbner) 7.9%. And these insects also are likely to prefer more root or rhizome part than the other ones. Based on these basic survey results, natural products researchers can obtain an important information in finding an insecticidal or fumigant compounds contained in the medicinal plants which any insect pests do not attack.

  • Objective: In this study, we analyzed the trend of patents registered prior to October 4, 2019, to understand the industrial trends in insect-derived medicinal materials used for the treatment of skin diseases. Methods: Using the WIPSON database, we collected information regarding the patents related to insect-derived materials for treating various skin diseases. Results: The patents registered prior to October 4, 2019, from Korea, Japan, the USA, China, and the EU, along with those registered under PCT were selected. There were 195 patents related to the use of insect-derived medicinal materials in treating various skin diseases such as psoriasis, inflammatory skin diseases, eczema, pruritus, and atopic dermatitis. China is mostly superior in total number of registered patents compared with the other countries. Korea was the major patent technology-holder for atopic dermatitis, but China dominated in the remaining categories of skin diseases. Upon first patent registration in 1992, there had been a continual increase in the number of patents. Especially, patents related to eczema, psoriasis, inflammatory skin disease were markedly increased. Most frequently used insect-derived medicinal materials was Scolopendra, Cicadidae Periostracum, Scorpions, Cantharides, and Batryticatus Bombyx. The insect-derived medicinal materials were generally used as a combined preparation with other medicinal materials in patents. Conclusion: This study could help to establish the basis for future research and development related treating skin diseases using insect-derived medicinal materials. In order to provide sufficient data, further study including analysis of rejected patents is needed.

  • Background: The current regulations regarding the storage of medicinal herbs do not define the storage temperature; instead, but the only requirement is that the plastic bags used for storing the medicinal herbs should be tightly sealed during storage. The practice of storing medicinal herbs at room temperature ($28^{\circ}C$), causes many problems, including growth of insect pests on the stored medicinal herbs. Thus, it is necessary to understand the effect of insect pests on the quality of medicinal herbs stored at room temperature ($28^{\circ}C$) for the improving the relevant regulations. Methods and Results: Cnidium rhizome and Angelica radix were infested with Lasioderma serricorne F. adults and incubated at $28^{\circ}C$ for 2.5 and 5 months. The population of L. serricorne was established rapidly, and left many holes, cadavers, and feces on the stored medicinal herbs, thereby greatly damaging the product appearance and hygiene. In addition, active ingredients of the medicinal herbs were significantly decreased, probably reducing their medicinal quality as well. Conclusions: These results indicate that the current regulations are not sufficient to prevent the establishment of storage insect pests and guarantee the quality and hygiene of stored medicinal herbs. Therefore, it is necessary to devise proper storage protocols and upgrade the current relevant regulations to maintain the quality of medicinal herbs during storage.

  • Anti-insect repellent silica sol from mixture with silica and anti-insect repellent solution extracted from medicinal herbs was prepared. The micron size porous sphere powder with anti-insect repellent solution was prepared by the spray drying method. The characteristic of anti-insect repellent powder using spray drying method was analyzed by FE-SEM, PSA, TGA with the concentration of anti-insect repellent sol (anti-insect repellent solution and silica) and conditions of spray drier. The average particle size of 4, 7 wt% and 10 wt% of anti-insect repellent sol concentration were 8.3, $9.5{\mu}m$ and $11.7{\mu}m$, respectively. The particle size is increasing with high concentration of anti-insect repellent sol. Other hands, particle size as the temperature of inlet nozzle and velocity of sol injection were nearly same at high velocity of gas injection. Also, Anti-insect repellent impregnation in porous sphere powder were confirmed by TGA methode and its thermal property was stable up to $200^{\circ}C$. We expect that anti-insect repellent powder is applied for plastic compound and process of film manufacture.

  • Despite the remarkable advancements of the modern medicine, the traditional system of medicine (TSM) still serves as a potential primary health care modality in the in low- and middle-income countries. The recent reports suggest that there is a renewed interest has been observed towards TSM in the developed countries too, because of the adverse side-effect of modern medicines. Medicinal plants have been widely serving as a rich source of therapeutic agent. Ethiopia is one of the most reserves rich countries in the world. It is renowned for well-diversified and natural resources in terms of its unique flora and fauna. Ethiopian deep-rooted tradition and culture largely depends on the usage of plants for their religious ceremonies, impressive festivals, traditional medicinal uses and other basic necessities. The present scrutiny is an attempt to understand the omnipotent nature of an Ethiopian Ethnomedicinal plant called Tinjute [vernacular name (local native language, Amharic); Otostegia integrifolia]. There are several studies suggest that Tinjute can be used as a natural medicine or health-promoting agents for various disorders and ailments. Nevertheless, in Ethiopia, it is renowned as an insect repellent to drive-away insect vector of diseases, particularly mosquitoes in the early evening. However, there are many more issues and challenges which must be urgently addressed to scientifically formulate various potent, efficacious, safe and highly selective phytotherapeutic agents and insects' repellent from the Tinjute plant in the near future.

  • Arthropod pests were surveyed from 132 herb species of 121 genera in 50 families of 32 orders at herb garden of Sancheong-gun Agricultural Development Technology Center in Sancheong, Gyeongsangnamdo province from October, 2005 to November, 2006. Ninety eight arthropod pests of 86 genera in 44 families of 9 orders were collected. Although less than 5 arthropod pests were collected from each herb, more than 5 arthropod pests were occurred on Hibiscus mutabililis, Peucedanum japonicum, Aralia cordata, Fraxinus rhynchophylla, Angelica decursiva, Rhaponticum uniflorum, Lonicera japonica, Betula platyphylla and Agrimonia pilosa. Out of collected pests, 98.5% of them damaged leaves of medicinal plants. The highest number of arthropod pests was recorded in May representing 36 species of 32 genera in 20 families of 6 orders. Most of them were collected from less than 5 medicinal plants. However, Atractomorpha lata, Dolycoris baccarum, Myzus persicae, and Nysius plebejus occurred on 42., 22, 20, and 15 medicinal plants, respectively. Atractomorpha lata and Myzus persicae had broad host ranges and seriously damaged. Aphis gossypii was dominant insect pest in May compared with Dolycoris baccarum in June. Atractomorpha lata in August and September, and Myzus persicae in October.

  • This experiment was carried out to elucidate the effect of the rain shelter and insect net on the growth and yield in Lycium chinense 'Cheongyang Cultivar'. The yield cultivated at the condition of the rain shelter and insect net were increase $92{\sim}106$ percent as that of nature conditions resulted from better growth and decrease of fruit attacked by anthracnose and injured by Eriophyes kuko. It had not significant between the ventilation and non-ventilation.
