为明确贵州省白背飞虱Sogatella furcifera (Horváth)全年世代尤其主害代发生危害规律，采用灯光诱测的方法系统地研究了近4年来贵州省4个不同稻区的白背飞虱灯下种群发生动态并进行了区域性对比，结果如下：三都稻区和惠水稻区的白背飞虱灯下始见日多在4月中下旬，锦屏稻区和道真稻区的灯下始见日稍晚，在4月下旬至5月中旬，各稻区灯下主峰日与始见日和始盛日均呈显著正相关；4稻区年度诱虫量差异较大，三都稻区的灯下虫量最多，而锦屏稻区最少，各稻区灯下种群中，白背飞虱的雌雄性比均大于1；在第3代灯下虫量上，三都与道真存在显著差异，在第6代虫量上三都与惠水、锦屏也存在显著差异，其他各代虫量间不同稻区并无显著差异。

英文摘要:

In order to identify the regular pattern of the annual generation damage, especially the main damage generation of Sogatella furcifera (Horváth) in Guizhou Province, systematic study was conducted to find out the population emergence dynamic of the S furciferain four different rice producing areas in Guizhou Province using the method of light trapping The results are as follows: S furcifera in rice producing area of Sandu and Huishui mostly began to appear in middle to late April; Areas of Jinping and Daozhen are latter and began to appear in late April to middle May; The peak date of the collected insects had significant positive correlation with the dates of its began to appear and bloom in each rice producing areas There is great difference in the induced insect amount of the four areas Population of all rice producing areas measured by lantern, the ratio of female to male all greater than 1 There is great amount difference between Sandu and Daozhen in light trap catches of the third generation of the insect，also there is great difference between Sandu,Huishui and Jinping in light trap catches of the sixth generation There is no significant difference in other generations of different rice producing areas.
