在单季稻和双季稻混作的安庆地区，褐飞虱和白背飞虱在晚稻田间的种群数量消长趋势基本相同的有１９９５年和１９９７年，混合种群数量达最大的日期都是在１０月上旬，且以褐飞虱为优势种群。１９９６年的混合虫量高峰期出现在９月５日，比１９９５年和１９９７年提前１个月，这与白背飞虱种群数量在前期突增，后期下降过快有关。晚稻田间的两种飞虱种群增长对异种飞虱的存在所产生的影响表现出不明显的反应。
In the Anqing area where single cropping rice and double cropping rice were mixed, the trend of population decline of Nilaparvata lugens and Sogatella furcifera in late rice field was basically the same in 1995 and 1997, and the maximum number of mixed population was in early October, and Nilaparvata lugens is the dominant species. The peak of the mixed pests in 1996 appeared on September 5, one month earlier than in 1995 and 1997, which was related to the rapid increase in the population of white-backed planthoppers in the early stage and the rapid decline in the late stage. The effects of the two planthopper population growths in the late rice crop on the presence of the different planthopper showed an insignificant response.
