[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.
