In order to find suitable area for seed potato production, this study was carried out to check the density of insect vector population and virus infection ratio at Mujugun Mupungmyeun Sangojeunglie(700 meters above the sea level) with Norchip, introduced variety from Canada and ordinary seed potatoes produced at Daek wanryeong area. The obtained results are sumarized as follows : 1. The six dominant insect vectors were .Acyrthosphon pisum Aphis gossypii,A.Rumicis, Aspiraecola, Myzus percicae and Lipaphis erysimi Aphis. genus population was 90 per cent among them, especially ,Aphis spiraecola occupied 64 per cent of the genus. 2. Among potato viruses. PVY which was infected by insect vector was 7 to 8 per cent showing a low infection ratio. 3. Irish Cobbler was infected by PVS, PVX, PVM and PVY in the order of severer to weaker infection, respectively, and Norchip showed the order of infection PVS, PVM, PVX and PVY. Thus, infection by PVS was the highest and that by PVY the lowest in both varieties. Therefore, this area was thought to be safe to produce seed potatoes in terms of insect vector problem if virus infection can be controlled by field sanitary management.

In order to find suitable area for seed potato production, this study was carried out through checking the density of insect vector population and virus infection rate at Jeonju, plain area in Jeonbug. The density of insect vector showed 2 peaks at middle of June and late of August. The dominants were Myzus persicae, Aphis gossypii Aulacorthum solani, Lipaphis erysimi in dense order. During potato growing season, the vinyl taped and insecticide treated plot showed lower than order plots in the density of potato virus vectors. On the average, PVM or PVY which is insect transmitted, reached 22 to 25% in increasing rate of virus infection and PVS or PVX which is contagious, showed 26 to 2874. However, in the vinyl taped and insecticide treated plot, the increasing rate of PVM or PVX infection showed only 9 to 12%, a remarkably low increasing rate of virus infection. Summarizing the aboves, it could be possible to produce seed potato in Jeonbug plain area if virus infection is controlled by field sanitary management.

This paper is aimed for preliminary surveying in order to virus free seed potatoes production in west coast area in Jeonbug. The seasonal fluctuation of potato virus vectors population, the potato virus Y (PVY) viruliferous ratio of Myzus persicae and PVY infection ratio, were checked in Jeonju and Kyewhado polder, from late April to middle July in 1981. The results are summarized as follows; 1. In Jeonju, aphids known to transmit virus diseases were 4 species, occupying 57% of the total trapped aphids. They were M, persicae, Aphis gossypii, Lipaphis erysimi and Aulacorthum solani. M. persicae was the dominant species among these occupy 84% of total potato virus vector aphids. In Kyewhado, aphids population was low than in Jeonju. Aphids Known to transmit virus diseases occupied 8% of total trapped aphids being the same species as in Jeonju The dominant species was A. gossypii which occupied 74% of total potato virus vector aphids. 2. The seasonal fluctuation of aphids showed the peak of it at the middle of June both in Jeonju and Kyewhado. 3. In Jeonju, the seasonal PVY viruliferous ratio of M. persicae showed 56% on the average, being the highest in the late of June(68%). 4. In Jeonju, the seasonal PVY infection ratio of showed 35%, and average increasing ratio of infection was 7%, being the highest in the late of June (11%). In Kyewhado, the seasonal PVY infection ratio of showed 12%, and average increasing ratio of infection was 2.4%, being the highest at early June(4%). 5. The positive correlation and the highly significant difference was observed between the seasonal PVY viruliferous ratio of M. persicae and PVY infection ratio in Jeonju.

The value of the potato virus disease infected in seed-potato tubers was tested by eye indexing serological method and indicator host reaction. The tubers were collected from six seed-potato fields in Cholla-Pukto and Daikwan-Lung. The virus regarded as PVX was identified by host range, dilution end point and electron micrography. The results of the above experiments are as follows; The value of total virus infection is 88% and the value of Cholla-Pukto areas is higher than that of Daikwan-Lung. The dilution end point of PVX, isolated from the above materials, is 10-5·10-6, and the virus particles are flexiable type as PVX common strain is.

씨감자 生産適地 選定을 爲하여 1973年에서 1979年에 걸쳐 高冷地(海拔 750m)인 全北 茂朱地域과 平暖地인 全州地域에서 裁培環境, 진딧물의 分布 및 媒介蟲密度, 裁培期間 中의 감자바이러스 感染率 및 씨감자의 罹病率을 比較 調査하였다. 진딧물의 採集은 진딧물 採集器(Yellow pan trap, 31×50×9cm)에 誘引된 것을 旬別로 蒐集하여 分類하였고, 바이러스 檢定은 催芽시켜 微量沈降反應法으로 하였다. 實驗 結果, 茂朱地域이 다음과 같이 씨감자 生産條件에 適格으로 나타났다. 1) 감자 裁培期間 中의 降雨量, 氣溫等이 씨감자 裁培에 알맞다. 2) 감자바이러스 媒介진딧물의 種類는 목화진딧물(Aphis gossypii)·복숭아혹진딧물(Myzus persicae)ㆍ무우테두리진딧물(Lipaphis erysimi)ㆍ싸리수염진딧물(Aulacorthum solani)ㆍ국화꼬마수염진디술(Macrosiphoniella sanborni)ㆍ완두수염진딧물(Acyrthosiphon pisum)의 6種이었다. 3) 媒介진딧물 中에서 優占種은 목화진딧물ㆍ복숭아혹진딧물ㆍ무우테두리진딧물 順이다. 4) 全體 진딧물의 密度는 茂朱地域이 全州地域의 17.4%(808/4,652)이고 媒介진딧물은 4.5%로 낮으며 全體 진딧물에 對한 媒介진딧물의 比率이 全州地域은 48.7%(2,266/4,652)인데 比하여 茂朱地域에서는 春作期에는 20%(77/380), 秋作期에는 9.8%(61/624)로서 茂朱地域이 훨씬 낮았다. 5) 진딧물의 季節的 發生消長은 溫帶型인 雙峰曲線을 보이나 冬奇主에서 夏奇主로 移動하는 前期에서 密度가 낮았다. 6) 우리나라에서 現在 普及되고 있는 씨감자의 바이러스 罹病率은 平均 27%이었으며, 供試品種 남작ㆍ시마바라ㆍ노-칲ㆍ데지마 間의 差異는 없었다. 7) 裁培期間 中 PVX(16.9%)ㆍPVS(25.4%)ㆍPVY(9.7%)ㆍPVM(10%) 等의 平均 感染率은 茂朱地域에서 16.6%로 全州地域에서의 24%보다 낮았다. 昆蟲媒介 바이러스 罹病率에 있어서도 茂朱地域(PVY+PVM=9.7%+10.0%)이 全州地域(PVY+PVM=26.5%+23.7%)보다 현저히 낮았다. 以上의 結果로 보아서 茂朱地域은 씨감자 生産適地로 思料된다. In order to survey a feasible are for seed potato production in the Jeonbug province, Muju, one of the alpine area (750m above sea level), was chosen. During 1973-1979 some basic investigations were carried out and compared with those at Jeonju with reference to climatic conditions, aphid distribution and their seasonal fluctuation, size of virus vector population, potato virus infection ratio during the potato growing season, and infection ratio of certified seed potatoes. Aphids were collected with yellow pan traps at intervals and virus diseases were checked by micro-precipitation test with sprouting seed potatoes. The experimental results obtained were shown as followed ; 1) Precipitation and temperature at Muju during potato growing season is suited for the cultivation of potatoes. 2) Aphids known to transmit virus diseases were of six species, that is, Aphis gossypii, Myzus persicae, Lipaphis erysimi, Aulacorthum solani, Macrosiphoniella sanborni, and Acyrthosiphon pisum. 3) The dominant species among the above aphids were Aphis gossypii, Myzus persicae, and Lipaphis erysimi in order. 4) The size of total aphids population at Muju was small, being only 17.4% of that at Jeonju, and the size of virus vector population at Muju was 4.5% of that at Jeonju. The ratio of virus vector per total aphids was remarkably high at Jeonju, being 48.7%, while low at Muju, being 20.0% in spring and 9.8% in autum. 5) The seasonal fluctuation of vectors showed a bimodal curve, one of the temperate types, having a low first peak at the transferring stage from winter host to summer host. 6) The virus infection ratio of certified seed potato reached as high as 27.0% on the average with no differences among tested cultivars (Irish cobbler, Shimabara, Norchip and Dejima). 7) During the potato growing season, the average infection ratio of PVX(16.9%), PVS(25.4%), PVY(9.6%) and PVM(10.0%) was low at Muju(16.6%) and comparatively high at Jeonju(24.0%). Besides, the infection ratio of insect transmitted virus showed markedly low at Muju (PVY+PVM=9.7%+10.0%) and high at Jeonju (PVY+PVM=26.5%+23.7%). In conclusion, Muju area is recommended as one of the feasible areas for seed potato production in the Jeonbug province.

In order to find whether Muju area is suitable for seed potato production, the density of insect vector population and the virus infection were checked in 1975. 1. The six dominant insect vectors which occupied 17% of the total captured aphids were myzus persicae, Aulacorthun solani Lipaphis erysimi Aphis gossypii, Aphis spiraecola and Among these, Aphis spiraecola had the largest population. 2. During the growing season, there was an increase of 15.1% in virus infection percentage, namely the virus infection percentage of seed potatocs produced in Muju area was 31.6 and that of harvested potatoes from same seed potatoes was 47.6% , while that of farmer's seed potatoes in Daekwanryeong area was 50. 3. There were significant differences between potato virus diseases. They were PVX, PVM, PVS and PVY in virus infection percentage order.
