| 摘 要： | 为了给重庆秀山县褐飞虱和白背飞虱的综合防治及异地预测预报提供理论依据,利用1990年以来该地区水稻预测圃两种飞虱发生的历史资料,较系统地研究了两种飞虱在该地区的发生及迁出规律.结果表明,该地田间稻飞虱为害呈明显双峰型,前期以白背飞虱为主,后期以褐飞虱为主,前后发生均重.在20世纪90年代,褐飞虱田间发生高峰期主要在8月上、中旬,近10年高峰期集中在8月下旬,白背飞虱在20世纪90年代田间发生高峰日主要集中在7月中旬,近10年高峰日集中在7月上旬；1990年-1999年,褐飞虱长翅型田间发生高峰期主要在8月中旬,近10年高峰期在8月下旬；1990年-1999年,白背飞虱长翅型田间发生高峰期主要在7月中旬和8月上旬,近10年高峰期在7月中、下旬.表明近20年,褐飞虱田间发生高峰期延迟,白背飞虱高峰期提前；褐飞虱迁出峰期延迟,白背飞虱迁出峰期提前. |

| Abstract: | In order to provide a theoretical basis for integrated control and forecasting of the brown planthopper,Nilaparvata lugens(Stl) and the white-backed planthopper,Sogatella furcifera(Horváth) in Xiushan County.Occurrence regularity of both insects in rice fields was analyzed by using historical data collected in naturally-occurring rice plots in Xiushan of Chongqing from 1990.The results showed that there were two occurrence peaks of rice planthopper in naturally-occurring rice plots.The first was mainly caused by S.furcifera and the second by N.lugens.The damages caused by the two insects during occurrence peaks were both great.The occurrence peak of N.lugens in rice fields was mainly in early or middle August in 1990’s,but in late August from 2000 to 2009 and S.furcifera was mainly in middle July in 1990s but in early July in the latest 10 years.The occurrence peak of macropterous N.lugens was mainly in middle August in 1990s but in late August in the latest 10 years and the occurrence peak of macropterous S.furcifera was in middle July or early August in 1990s but in middle or late July in the latest 10 years.The occurrence peak of N.lugens had a tendency of postponing and S.furcifera had a tendency of advancing.The emigration peak of N.lugens had a tendency of postponing and S.furcifera had tendency of advancing. |
