中文摘要：
【目的】 明确稻飞虱迁飞种群的上灯行为节律，以指导其大田迁入种群和迁出种群的发生预测与灾变预警。【方法】 本研究运用逐时自动灯诱装置对2010和2011连续两年稻飞虱迁飞种群的上灯行为节律进行了系统研究。【结果】 灰飞虱Laodelphax striatellus迁飞种群上灯始见期和灯诱虫量年际间差异不明显，白背飞虱Sogatella furcifera和褐飞虱Nilaparvata lugens迁飞过境种群上灯始见期和灯诱虫量年际间差异较大。此外，灰飞虱迁飞种群的特大高峰期和高峰期逐时灯诱虫量百分比与一般上灯期和零星上灯期相比突出了晨暮双峰型中的暮峰型上灯行为特点；白背飞虱迁飞种群特大高峰期逐时灯诱虫量百分比与高峰期和一般期相比突出了晨暮双峰型中的晨峰型生物学特性。【结论】 稻飞虱迁飞种群的上灯行为节律存在种的特异性，这一行为节律除了受环境因素的影响外主要与其生物学特性有关。
英文摘要：
[Objectives] This study was carried out to confirm the light-trapped behavioral rhythms of migratory populations of rice planthoppers, including brown planthopper (BPH) Nilaparvata lugens, small brown planthopper (SBPH) Laodelphax striatellus and white backed planthopper (WBPH) Sogatella furcifera, which is, in turn, to guild. The occurrence forecasting and outbreak early warning of the immigration and emigration populations of these three species of rice planthoppers in paddyfields. [Methods] The behavioral rhythms of rice planthoppers, N. lugens, L. striatellus and S. furcifera were researched by using the blacklamp with hourly automatic light traping device from 2010 to 2011 in this study. [Results] The results indicated that there were no obvious differences in the beginning date and total abundances of light-trapped SBPH between 2010 and 2011, while obvious differences in the beginning date and total abundances of light-trapped BPH and WBPH were shown between 2010 and 2011. Moreover, based on the percent data of hour by hour intervals of light-trapped L. striatellus and S. furcifera from 6: 00 p.m. to 6: 00 a.m., the behavioral rhythms of evening peak of light-trapped SBPH were found for the migration populations on the days of super peak and normal peak compared to the normal days and sporadic days; and the behavioral rhythm of morning peak of light-trapped WBPH was found for the migration populations on the days of super peak compared to the normal peak and normal days. [Conclusion] The light-trapped behavioral rhythms of migratory populations of rice planthoppers shows species specific performance, mainly owing to their biological characteristics besides of the effects of environmental factors.
