정명표,김광호,이상계,박홍현 한국곤충학회 2013 Entomological Research Vol.43 No.3

According to the Intergovernmental Panel on Climate Change (IPCC), the global mean surface temperature increased by 0.74°C between 1906 and 2005, and is expected to continue rising. In Korea, the temperature increased rapidly by 1.8°C between 1912 and 2010. The effect of global warming are expected to cause phenological changes in exothermic organisms such as insect pests which are highly dependent on temperature. In present study, we estimated the emergence time of three lepidopteran pests (Carposina sasakii, Grapholita molesta, and Phyllonorycter ringoniella) in apple orchards during 2000, 2020s, 2050s, and 2090s, by means of Representative Concentration Pathway (RCP) 8.5 climate change scenario. In comparison with 2000, the emergence of C. sasakii is predicted to occur 5.5 ± 0.49 days earlier in 2020s, 14.9 ± 0.40 days earlier in 2050s, and 40.0 ± 0.75 days earlier in 2090s; the emergence of G. molesta is predicted to occur 8.2 ± 0.36 days earlier in 2020s, 16.9 ± 0.40 days earlier in 2050s, and 49.7 ± 0.61 days earlier in 2090s; and the emergence of P. ringoniella is predicted to occur 9.0 ± 0.34 days earlier in 2020s, 20.5 ± 0.58 days earlier in 2050s, and 52.5 ± 0.63 days earlier in 2090s. The number of generations a year is expected to increase by 0.5–2.8 generations in 2050s, 1.3–6.7 in 2090s. Our predictions provide basic data for the development of insect pest management strategies in spring under conditions of global warming.

BACKGROUND: A region can be divided into agroclimatic zones based on homogeneity in weather variables that have greatest influence on crop growth and yield. The agro-climatic zone has been used to identify yield variability and limiting factors for crop growth. This study was conducted to classify agro-climatic zones in the state of Mato Grosso in Brazil for predicting crop productivity and assessing crop suitability etc. METHODS AND RESULTS: For agro-climatic zonation, monthly mean temperature, precipitation, and solar radiation data from Global Modeling and Assimilation Office (GMAO) of National Aeronautics and Space Administration (NASA, USA) between 1980 and 2010 were collected. Altitude and vegetation fraction of Brazil from Weather Research and Forecasting (WRF) were also used to classify them. The criteria of agro-climatic classification were temperature in the hottest month (30℃), annual precipitation (600 mm and 1000 mm), and altitude (200 m and 500 m). The state of Mato Gross in Brazil was divided into 9 agro-climatic zones according to these criteria by using matrix classification method. CONCLUSION: The results could be useful as information for estimating agro-meteorological characteristics and predicting crop development and crop yield in the state of Mato Grosso in Brazil.

Recently, climate change scenarios were substituted by the Special Report on Emission Scenarios (SRES) for Representative Concentration Pathway (RCP). Using the RCP scenario, the World Meteorological Organization (WMO) produced new climate change scenarios. Further, the National Institute of Meteorological Research (NIMR) of Korea produced new climate change scenarios for the Korean Peninsula. In this study, emergence time of small brown planthopper (SBPH), Laodelphax striatellus and the number of generations a year were estimated during climatic normal year (1981-2010) with previous studies and they were predicted during 2050s (2045-2054) and 2090s (2085-2094) by means of RCP8.5 climate change scenario. In comparison with $176.0{\pm}0.97$ Julian data in the climatic normal year, the emergence time of overwintering SBPH was predicted to be $13.2{\pm}0.18$ days ($162.8{\pm}0.91$ Julian date) earlier in 2050s and $32.1{\pm}0.61$ days ($143.9{\pm}1.08$ Julian date) earlier in 2090s. The SBPH was expected to produce an additional $2.0{\pm}0.02$ generations in 2050s and $5.2{\pm}0.06$ generations in 2090s. 최근 WMO는 온실가스 배출량 시나리오(SRES)를 대신하여 대표농도경로(RCP)를 바탕으로 새로운 기후변화 시나리오를 생산하였으며 기상연구소는 RCP 시나리오를 바탕으로 한반도의 새로운 기후변화 시나리오를 생산하였다. 본 연구에서는 과거 관측값을 바탕으로 평년(1981-2010)의 애멸구의 우화시기와 세대수를 추정하였으며, RCP 8.5 시나리오를 바탕으로 2020년대(2015-2024), 2050년대(2045-2054)와 2090년대(2085-2094) 애멸구의 우화시기와 세대수를 예측하였다. 평년 애멸구 월동 1세대수의 우화일인 $176.0{\pm}0.97$일과 비교하여 2050년대에서는 $13.2{\pm}0.18$일($162.8{\pm}0.91$일), 2090년대에는 $32.1{\pm}0.61$일($143.9{\pm}1.08$일) 앞당겨질 것을 예측되었다. 그리고 애멸구의 연간 세대수는 2050년대에서는 현재보다 $2.0{\pm}0.02$세대, 2090년대에는 $5.2{\pm}0.06$세대 증가할 것으로 예측되었다.

Insecticidal activity of recombinant baculovirus expressing both spider toxin isolated from Araneus ventricosus and Bacillus thuringiensis crystal protein fused to a viral polyhedrin

정명표,최재영,Xue Ying Tao,진병래,제연호,박홍현 한국곤충학회 2012 Entomological Research Vol.42 No.6

A novel recombinant Autographa californica nucleopolyhedrovirus (AcMNPV), ApPolh5‐3006AvTox2, co‐expressing two insecticidal toxins, one isolated from the spider Araneus ventricosus, and the other from Bacillus thuringiensis, was constructed to improve the insecticidal activity of AcMNPV. The recombinant virus was designed to express insect‐specific spider toxin, Av‐Tox2, under control of the early promoter from Cotesia plutellae bracovirus (CpBV). In addition, the B. thuringiensis cry1‐5 crystal protein gene was introduced into the genome of this recombinant virus by fusing it with the viral polyhedrin gene, thus creating a hybrid polyhedrin‐cry1‐5 gene under control of the polyhedrin gene promoter. Reverse transcription‐polymerase chain reaction (RT‐PCR) analysis revealed that both Av‐Tox2 and Polyhedrin‐Cry1‐5 fusion protein were successfully expressed in the infected cells. In addition, SDS‐PAGE revealed that Polyhedrin‐Cry1‐5 fusion protein expressed by recombinant viruses occluded the polyhedra. ApPolh5‐3006AvTox2 showed significantly reduced LD50 and ST50 values against both Plutella xylostella and Spodoptera exigua larvae. These results strongly suggested that coexpression of spider and B. thuringiensis insecticidal toxins could be successful in improving the insecticidal activity of baculoviruses.

Reference evapotranspiration estimates based on meteorological variables over Korean agro-climatic zones for rice field

정명표,허지나,심교문,김용석,강기경,최순군,이병태 한국농림기상학회 2019 한국농림기상학회지 Vol.21 No.4

This study was conducted to estimate annual reference evapotranspiration (ET0) for the agro-climatic zones for rice paddy fields in South Korea between 1980 and 2015. The daily ET0 was estimated by applying the Penman-Monteith method to meteorological data from 61 weather stations provided by Korean Meteorological Administration (KMA). The average of annual ET0 from 1980 to 2015 was 1334.1±33.89 mm. The ET0 was the highest at the Southern Coastal Zone due to their higher air temperature and lower relative humidity. The ET0 had significantly increased with 2.81 mm/yr for the whole zones over 36 years. However, the change rate of it was different among agro-climatic zones. The annual ET0 highly increased in central zones and eastern coastal zones. In terms of correlation coefficient, the temporal change of the annual ET0 was closely related to variations of four meteorological factors (i.e., mean, minimum temperatures, sunshine duration, and relative humidity). The results demonstrated that whole Korean agro-climatic zones have been undergoing a significant change in the annual ET0 for the last 36 years. Understanding the spatial pattern and the long-term variation of the annual ET0 associated with global warming would be useful to improve crop and water resource managements at each agro-climatic zone of South Korea.
