Abstract

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 <TEX>$176.0{\pm}0.97$</TEX>일과 비교하여 2050년대에서는 <TEX>$13.2{\pm}0.18$</TEX>일(<TEX>$162.8{\pm}0.91$</TEX>일), 2090년대에는 <TEX>$32.1{\pm}0.61$</TEX>일(<TEX>$143.9{\pm}1.08$</TEX>일) 앞당겨질 것을 예측되었다. 그리고 애멸구의 연간 세대수는 2050년대에서는 현재보다 <TEX>$2.0{\pm}0.02$</TEX>세대, 2090년대에는 <TEX>$5.2{\pm}0.06$</TEX>세대 증가할 것으로 예측되었다. 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 <TEX>$176.0{\pm}0.97$</TEX> Julian data in the climatic normal year, the emergence time of overwintering SBPH was predicted to be <TEX>$13.2{\pm}0.18$</TEX> days (<TEX>$162.8{\pm}0.91$</TEX> Julian date) earlier in 2050s and <TEX>$32.1{\pm}0.61$</TEX> days (<TEX>$143.9{\pm}1.08$</TEX> Julian date) earlier in 2090s. The SBPH was expected to produce an additional <TEX>$2.0{\pm}0.02$</TEX> generations in 2050s and <TEX>$5.2{\pm}0.06$</TEX> generations in 2090s.
