Nomenclatural changes are provided for Sorbus-feeding Cacopsylla moiwasana (Kuwayama, 1908) species group. Thirteen Palaearctic Cacopsylla species have been recorded from Sorbus L. (Rosaceae), and of these, seven species restricted to East Asia. Among the East Asian species, four Japanese species, i.e. C. elegans Inoue, 2004, C. jezoensis (Miyatake, 1963), C. midoriae (Miyatake, 1963) and C. moiwasana (Kuwayama, 1908), assigned to C. moiwasana species group. Above the latter three species very similar to each other, allopatrically distributed, and all or some of them could be synonymous. The present investigation of the type material resulted in confirmation that Psylla jezoensis and P. midoriae should be treated as junior synonym of P. moiwasana. The following synonyms are proposed: Cacopsylla moiwasana (Kuwayama, 1908) = Psylla jezoensis Miyatake, 1963, syn. nov., Psylla midoriae Miyatake, 1963, syn. nov. The species are newly recorded from Korea.

동소동속종인 복숭아순나방과 복숭아순나방붙이는 우리나라에서 여러 가지 과수의 주요 해충으로 알려져 있다. 본 연구에서 우리는 장미 과(Rosaceae) 과수인 복숭아나무, 자두나무, 사과나무, 배나무, 모과나무의 과실을 가해하는 복숭아순나방과 복숭아순나방붙이 유충을 채집하 여 분자동정법을 이용하여 종을 동정하여 과종별로 두 종의 분포 비율을 비교하였다. 유충을 동정한 결과, 복숭아 과실을 가해하는 종은 거의 대 부분 복숭아순나방이었던 반면, 자두 과실을 가해하는 것은 모두 복숭아순나방붙이인 것으로 나타났다. 사과, 배, 모과 과실은 두 종이 상당하는 비율로 같이 분포하였는데, 사과와 모과에서는 복숭아순나방붙이에 의한 피해가 상대적으로 많았으나 유의한 우점은 발견되지 않았고, 배 과실 에서는 복숭아순나방이 유의하게 우점하여 분포하였다. 이 결과들은 과수원에서 이 해충들의 합리적인 관리전략을 수립하는데 유용할 것이다.

For the purpose of developing Korean Herbalogy with the plants of Rosaceae which grow wild and is planted in Korea, the these and writings on herbalogy, from literature of successive generations, have been thoroughly investigated and the results obtained as follows: 1. There were totaled to 36 genera and 262 in Korea and among them medicinal plants are 27 genera, 117species, some 44% in total, but the number of species may be added because of the similiar plants. 2. According to sum of 262 species in Rosaceae family, they were classified into Agrimonia genera 3, Potentilla genera 26, Prunus genera 48,pyrus genera 17, Rosa genera 24, Rubus genera 28, Sorbaria genera 17, Spiraea genera 20. Thus it was noticed that Prunus genera was the main kind in total. 3. According to the oriental names which can be used for medical purpose, the medicinal plants belonging to the Rosaceae family were classified as Herba 24, Radix 43, Foilum 31, Fructus 48, Semen 11, cortex 14, Lignum, Ramulus;12 each Flos 3, pericarpium 3, resina 2, the others 6. so Fructus is 24% of all and it is the most applied in the clinical treatments. 4. According to nature and flavour of medicinal plants, they were classified into balance 84, warmth, heat; 44 each, cold, cool; 35 each bitter taste 79, sweet taste 74, sour taste 61 thus it was noticed that balance and bitter taste is the main in nature and flavour of medicinal plants 5. According to meridian tropism of herbs they were classified into liver meridian 50 lung meridian 28, stomach meridian 22, spleen meridian 20, heart meridian 19 thus it was noticed that liver meridian is the main kind 6. According to the Properties and Principal curative action, they were classified into drugs for treating detoxicant 72, drugs for treating febrifugal 55, drugs for invigorating blood circulation 53, drugs for removing dampness 46, drugs for expelling wind and drugs to stop bleeding 38 each, drugs to cure tramatic swelling and drugs for relieving pain 36 each. Thus it was noticed that drugs for treating detoxicant and febrifugal was the main kind 7. It was researched that toxic drugs include minor toxin were 10 kinds From this result, it was revealed that Fructus was the main kind in the plants for medical purpose of Rosaceae. and toxic plants was slightly poisonous that it will be used for clinical treatments more easily. It is considered that many experiments and clinical approaches must be continued to use Rosaceae plants widely.

A comparative petal micromorphology of 15 taxa of tribe Sorbarieae was carried out using scanning electron microscopy (SEM) in order to evaluate their taxonomic and systematic implication. The characteristics of both adaxial and abaxial side of petal epidermal cells such as shape, arrangement, anticlinal wall and cuticular sculpture were described in detail. The Sorbarieae petal epidermal cells were identified as papillate or conical papillate (PCS) and rectangular-rugose tabular (TRS). Three types of petal micromorphology were found within the tribe based on the cell patterns of adaxial and abaxial side. Type I. PCS-TRS, Type II. PCS-PCS, Type III. TRS-TRS (adaxial-abaxial side). The petal epidermal cell types, anticlinal cell wall, and cuticular sculpture represent not only taxonomical importance for identification between or within the genera but also systematic implication. Moreover, this study provides a relation between petal epidermal cell pattern and insect pollinator (entomophily; melittophily) as an additional case.

The antioxidant activities and total phenolics of four Rosaceae species Pourthiaea villosa (Thunb.) Decne, Sorbus commixta Hedlund, Sorbaria sorbifolia var. stellipila Maxim and Pyrus pyrifolia (Burm.f.) Nakai were determined. Phenolic content (polyphenol and flavonoid), radical scavenging activities [2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino-bis (3-ethylnezthiazoline-6-sulfoic acid) (ABTS)] and ferrous ion chelating effect were evaluated. Total polyphenol and flavonoid contents were highest in Pourthiaea villosa (Thunb.) Decne and lowest in Pyrus pyrifolia (Burm.f.) Nakai. Phenolic contents of Pourthiaea villosa (Thunb.) Decne was 331.45±7.78 and 90.4±3.5 mg·g-1. DPPH and ABTS radical scavenging activities were found to be lowest in Sorbus commixta Hedlund whereas Sorbaria sorbifolia var. stellipila Maxim and Pourthiaea villosa (Thunb.) Decne showed relatively good DPPH and ABTS radical scavenging activities. Ferrous ion chelating effect was highest in Pyrus pyrifolia (Burm.f.) Nakai (1.05±0.04 mg·ml-1) and lowest in Sorbus commixta Hundlund (4.22±0.71 mg·ml-1).
