摘　　要：在广东省广州市花都区和白云区系统调查了稻菜轮作田、水稻连作田的水稻害虫褐飞虱Nilaparvata lugens(Stl)及其捕食性天敌蜘蛛的数量,结果表明:与水稻连作相比,花都区稻菜轮作模式总体上降低了褐飞虱数量,同期最高降低66.6%,对田间蜘蛛数量影响不明显;白云区的稻菜轮作模式也显著降低了褐飞虱的数量,同期最高降低56.3%,对蜘蛛数量的影响也不明显。稻菜轮作模式能有效降低田间褐飞虱数量,有利于水稻生产。The density of the brown planthopper（ BPH） Nilaparvata lugens（ Stal） and spiders was investigated in two farming patterns： rice- vegetable rotation and rice continuous cropping,in the paddy fields of Huadu and Baiyun district of Guangzhou City. The results showed that in Huadu district,rice-vegetable rotation often reduced BPH density in paddy fields,up to 66. 6% reduction compared to the control（ rice continuous cropping）,but the effect on the density of spiders was not obvious; in Baiyun district,rice- vegetable rotation significantly decreased BPH density,up to 56. 30% reduction compared to the control,the density of spiders did not change obviously. Our investigation suggests that rice-vegetable rotation effectively reduce BPH density in paddy fields,and is beneficial to rice production.
