摘　　要：于2010-2013年研究低空捕虫网在稻飞虱监测预警中的应用效果。结果表明,低空捕虫网对灰飞虱、白背飞虱、褐飞虱3种稻田飞虱都有捕获效果,对迁入飞虱种群的捕集效果较差,对本地羽化的飞虱捕集效果较好,特别是对灰飞虱,低空网捕集量大,峰次多,虫峰较诱虫灯明显,且不受风雨、电源等因素影响,虫情信息可靠,虫种比较单纯,容易分种计数,网捕灰飞虱成虫峰与田间虫峰有明显相关,验证了灰飞虱从小麦田向秧田扩散的对应关系。低空网对灰飞虱预测有较好的应用价值,但对白背飞虱和褐飞虱的迁入预警作用不明显。The application effect of low altitude net trap in monitoring and early warning of rice planthopper during 2010 - 2013 were studied. The trapping effect of three kinds of rice planthopper （Laodelphgax striatellus, Sogatella furcifera, Nilaparvata lugens）was studied with the low altitude trap net, the result showed that the low altitude trap net had obvious effect on small brown planthopper（SBPH） with large quantity, numbers of significant peaks, and it was not infected by rain and electric power. Compared with the lamp trap, the information of SBPH by net trap was reliable, and the catcher insects were easy to classify for only kinds of insect variety, the relationship between the peak of trap net and the survey data verified the spread or migration from wheat field to rice seedling. Contrary to the local planthopper population, the net trap was not an effective method in forecasting migration planthopper population, such as the white backed planthopper（WBPH） and the brown planthopper （BPH）.
