为了有效地控制白背飞虱的为害,我们于1976至1983年间,对杂交水稻白背飞虱的发生动态,药剂防治对策进行了调查研究.发生动态(一)灯下成虫消长动态据1976～1983年资料分析,镇江丘陵地区白背飞虱成虫于5月下旬始见,迁入盛期为6月底至8月底,主峰期常年在7月上、中旬,有些年份7月下旬到8月上旬也可出现迁入峰.9月中旬后虫量逐渐减少,10月下旬终见,全年发生4～5代.按照灯下成虫的消长动态,大致可以分为三种发生型(图1).
In order to effectively control the whitebacked planthopper infestation, we investigated the dynamics of the whitebacked planthopper (Sogatella furcifera) and its control strategy in hybrid rice from 1976 to 1983. Occurrence Dynamics (I) 1983 data analysis, Zhenjiang hilly area of whitebacked planthopper saw in late May, moved into the peak for the end of June to the end of August, perennial peaks in July, mid-year, some years from late July to early August But also appeared immigration peak in mid-September after the amount of insects gradually reduced in late October, the end of the year, occurred 4 to 5 generations in accordance with the dynamics of growth and development of adults can be divided into three types (Figure 1) .
