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。
In order to clarify the occurrence of whiteflies Sogatella furcifera (Horváth) in Guizhou province throughout the year, the white-backed planthopper lamp was systematically studied by light-induced method. Under the population dynamics and carried out a regional comparison, the results are as follows: Sanduo rice paddy area and the white-backed planthopper light see more days in late April, Jinping rice and daimu rice In the late April to mid-May, the main peak of the light under each rice area showed a significant positive correlation with the first seeded day and the first start of the day. The population of lampworms in the district was the highest while that in Jinping was the least. The ratio of female and male of Sogatella furcifera was greater than 1 in the light under the light of each rice region. In the third generation of light, Significant differences in the sixth generation of insects on the amount of Sandu and Huishui, Jinping significant differences exist, other generations of insects between different rice areas did not differ significantly.
