본 시험은 이화명충과 과수의 잎말이류 및 Codling Moth의 Pheromone등 모두 15종의 합성 Pheromone을 도입하여 국내해충의 예찰과 방제에 이용가능한 Pheromone의 선발코자 수행하였다. 이화명충 Pheromone은 미국의 열대생산물연구소에서 합성한 것을 사용하였으며 과수해충의 Pheromone은 Comell 대학과 Zoecon회사에서 공급받았다. 본 시험의 결과는 다음과 같다. 1. 이화명충의 미교미 암컷을 넣은 Trap이 합성 Pheromone을 넣은 Trap보다 숫컷을 유인하는 능력이 컸다. 2. 이화명충의 합성 Pheromone은 설치 후 시간이 경과함에 따라 유인력이 감소하여 발생정점을 잡을 수 없었다. 3. 과수잎말이류 해충중 복숭아순나방이 OFM과 LAW Pheromone에 가장 많이 유인되었다. 4. OBLR, RBLR, SPAR, 그리고 ArcM Pheromone에 수종의 과수잎말이류 나방이 다수 유인되었으나 기타 8종의 Pheromone에는 유인나방의 수가 적었다. 5. 본 시험의 결과로 보아 해충의 발생예찰에 이용가능 할 것으로 생각되는 합성 Phreomone과 이들의 적용해충은 다음과 같다. OFM, LAW: 복숭아순나방 OBLR: 사과무늬잎말이나방 OBLR, RBLR, ArcM: 한국잎말이나방, 검모무늬 잎말이나방, 사과잎말이나방 SPAR, TBM Pyroderces속의 일종 Pheromones of several insect species were evaluated in a screening program in terms of their usefulness in pest forecasting and control in Korea. Species included striped rite borer (Chilo suppressalis) and tortricid moths, which attack deciduous fruit, and colding moth. The pheromone of striped rice borer was supplied through the courtesy of the Tropical Products Institute, London. Pheromones of other species were obtained from Cornell University and the Zoecon Corporation of Palo Alto, California. 'rho results of this experiment were as follows: 1. Live traps containing virgin striped rice borer female moths were more effective in attracting male moths than were the pheromone traps. 2. Since the effectiveness of the striped rice borer pheromone decreased dramatically with time, it was difficult to estimate the peak tine of the borer emergence. 3. The primary species trapped in deciduous fruit orchards was the oriental fruit moth, Grapholitha molesta. The traps were baited with the phermones, OFM and LAW. 4. Several moth species were trapped with OBLR. RBLR. SPAR and ArcM phermones but few were trapped with the remaining eight tortricid pheromones. 5. The following tortricid pheromones might be useful for forecasting the species given: OFM, LAW : Grapholitha molesta OBLR : Archips breviprecanus OBLH, RBLR, ArcM : Archippus coreensis Archips fuscocupreanus Hoshinoa longicellana SPAR, TBM ; Phyroderces sp.

A Series of studies were and is going to be carried out to provide a direction for the improvement of the potato cultivation at the east coastal region(Yeongdong region) in kang weon province. In this report, We present the results obtained from the studies performed during the period of 1985 to 1987. Firstly, We investigated the current situation of the potato cultivation as influenced by the climatic conditions for this region. Secondly, We corroborated the impact of late blight on potato yield in accordance with the tiem and degree of late blight occurrence, and we also tested the use of the Moving Graph method to product the occurrence of late blight by utilizing several, important weather data of the Sokcho, Kangneung, and Samcheock areas. The results obtained are as follows. 1. Since the weather conditions such as average temperature, Diurnal temperature range, Duration of sunshine in the Southern part of the Yeongdong region are more favorable for potato growth as compared with those in the Northern part, areas for the early Potato crop, which can be harvested before the hot, rainy summer season and when the potato price is high, could be expanded by improving cultivation techniques and by using high-quality seed potatoes and stress-resistan varieties. 2. The recommended early potato varietes of Superior and Irish Cobbler accounted for 63% of the Potato varieties used in the Yeongdond region, the recommended fall-crop varietes of Dejima and Shimabara for 13%, and nonrecommended vareties for 24%. 3. Seed potatoes obtained through the formal seed potato supply system only accountes for around 20% of the seed potatoes planted in the Yeongdong region, suggestion a problem of yield reduction because of seed potato degeneration. 4. Data from a study in 1986 showed that late blight was observed in Kangneung and Samcheok on July 9th (96 days after planting) and in Sokcho on June 30 th(87 days after planting), and that yield reductions due to late blight occurrence were 13% in Kangneung and 20% in Sokcho, respectively. 5. In the Yeongdong region almost no chemical control for late blight was being practiced : therefore, once or twice of chemical control for early potato crop and periodic control for up-land crop are recommended. 6. In 1986 the high coincidence of actual temperature, precipitation, and relative humidity with estimated climatic conditions favorable for late blight occurrence permitted the Moving Graph construction to correctly forecast the warning for late blight occurrence ; however, late blight occurrence could not be so correctly forecasted in 1985 and 1987 since the actual relative humidity did not coincide with estimated relative humidity favorable for late blight occurrence. 7. Utilization of the Mowing Graph method, which includes relative humidity, during the potato cultivation in the Yeongdong region is believed to be useful for the curtailment of cost and labour as well as for yield increase.
