담배가루이 유인용 LED 선발과 기주식물이 초기 유인력에 미치는 영향
권덕호,권민정,양다영,안율균,홍규현,박미리,Kwon, D.H.,Kwon, M.J.,Yang, D.Y.,Ahn, Y.K.,Hong, K.H.,Park, M.R. 국립한국농수산대학교 교육개발센터 2020 현장농업연구지 = Journal of practical agricultural resear Vol.22 No.2
시설 재배지 내 담배가루이의 밀도 예찰을 위하여 여러 종류의 LED등(청색등, 녹색등, 적색등, 백색등)에 대한 유인력을 평가하였다. 유인력 평가는 황색끈끈이트랩에 부착된 담배가루이의 포집 수를 대상으로 하였다. 평가용 케이지 내에서 기주식물이 없는 조건에서 유인력은 청색등(107.3±2.5마리) > 백색등(83.0±12.1마리) > 적색등(58±21.8마리) > 녹색등(39.7±8.1마리) 순서로 나타났다. 먹이를 주입한 상태에서 유인력은 청색등(52±17.4) > 적색등(38.7±5.8) > 녹색등(12.7±1.5) > 백색등(11.7±5.0) 순서로 관찰되었다. 두 실험 조건에서 모두 청색등에서 유인력이 가장 높은 것으로 나타났다. 기주식물을 넣었을 때 LED등 유인력이 감소하는 것을 확인하였는데, 백색등(85.9%) > 녹색등(68.1%) > 청색등(51.6%) > 적색등(33.3%) 순서로 나타나 기주식물이 LED 등 유인력 감소에 영향이 있음을 확인하였다. 상대적인 방제력 평가에서는 기주식물을 처리한 6시간 이후에 적색등(66.7%) > 청색등(48.5%) > 녹색등(31.9%) > 백색등(14.1%) 순으로 높았다(F<sub>3,8</sub> = 14.7, P = 0.001). 따라서 청색등은 초기 유인력이 매우 높은 특징을 보였고, 적색등은 기주식물의 투입에 영향을 받지 않아 담배가루이 유인에 적합성이 있음을 확인하였다. 야외 실증실험에서는 낮은 온도조건에 의해 높은 유인력은 관찰되지 않았지만, 청색등과 적색등에서 대조구 대비 높은 유인력이 관찰되었다. 향후 적색과 청색을 활용한 LED등은 시설재배지 내 담배가루이의 예찰에 활용할 수 있을 것으로 기대된다. Four LEDs (blue, green, red, and white light) were tested to identify the most attractive wave length to utilize as the forecasting tools for the B. tabaci in glass houses. Attractiveness was evaluated by the total number of the B. tabaci attached to a yellow sticky trap. In the condition of no host plant supplement, the attraction efficacy was ordered from high to low as blue light (107.3±2.5), white light (83.0±12.1), red light (58±21.8), and green light (39.7±8.1). In the supplement of the host plant, the attraction was observed in the order of blue light (52±17.4), red light (38.7±5.8), green light (12.7±1.5), and white light (11.7±5.0). In both experimental conditions, blue light showed the highest attraction. In terms of the host plant effect to LED attraction, it varied following as white light (85.9%), green light (68.1%), blue light (51.6%), and red light (33.3%). This result suggests that red light is the least affected by the host plant. In the evaluation of the relative control efficacy, it was determined following as red light (66.7%), blue light (48.5%), green light (31.9%) and white light (14.1%) (F<sub>3,8</sub> = 14.7, P = 0.001). Taken together, blue light had a very high initial attraction, and red light was revealed low attraction effect by the supplement of the host plant. In field demonstration experiments, a high attractive efficacy was not observed due to low-temperature conditions, but similar higher attractive efficacy was observed in blue and red lights compared to the control. The commercialization of LEDs using red and blue in the future is expected to provide important information regarding B. tabaci population density forecast in glass house.

Purpose: The purpose of this study was to examine the correlation of alcohol use disorder, social support and depression of the college students. Method: In this descriptive design study, 334 university students were recruited through convenient sampling from October, 2015 to January, 2016. Questionnaires used for online Google docs were AUDIT-K(Alcohol Use Disorders Identification Test-Korea), MSPSS(Multidimensional Scale of Perceived Social Support) and SDS(Self - Rating Depression Scale). Data were analyzed with descriptive statistics, independent t-test, one way ANOVA with Scheffe's test, and Pearson’s coefficient using SPSS 22.0 program. Result: 230 students of the 334 college students(68.8%) were classified into alcohol use disorder group. There was a significant correlation between the degree of social support and depression among all participants(r=-.45, p=.000). However, there was no correlation between alcohol use disorder and depression(r=.23, p=.006) and between alcohol use disorder and social support(r=.02, p=.758). Conclusion: This study showed a relationship between social support and depression, not the alcohol use disorder. This result can be used as the basic data in nursing research about alcohol use disorder, social support and depression of college students. Also, Further researches are needed to examine the factors that affect alcohol use disorder of college students, as well as depression and social support.
