摘要: For this study we collected eight years (2006-2013) of data on Chongming Eco-island in China, analyzing the effects of large-scale agriculture on the occurrence of the rice leaf roller, Cnaphalocrocis medinalis Guenee, a dominant foliage feeder in rice ecosystems. We found that the peak of the C. medinalis population was obvious in 2006, 2007 and 2009, with more than 400 adult C. medinalis trapped in a single insecticidal lamp each day and more than 500 individuals per 66.7 m(2) in paddy field. We found a significantly positive correlation between the number of adult C. medinalis trapped in the lamp and the number of moths observed in the paddy field and these two monitoring indicators of C. medinalis were both significantly influenced by average daily temperature. Our study suggests that global warming might promote the occurrence of C. medinalis in large-scale agriculture in the future. (C) 2015 Elsevier B.V. All rights reserved.
