In order to improve the cost-effective control of occurrence and damage of rice brown planthopper, Study of super indica japonica hybrid rice Yongyou 6 of brown planthopper population reproduction rate density effect. The reproductive rate and variation dynamics of rice brown planthopper in super rice was also investigated and analyzed. Field test results showed that the population amount of rice brown planthopper in super rice during tillering stage and booting stage gradually increased with the increasing amount of released pest and its growth amount gradually increased with the advancement of growth stage. However, as the density reached a certain limit during gain filling stage (>250 head/cluster), the population amount during maturity stage showed decline trend with the increasing density.
Key words: Reproductive rate, rice brown planthopper, super indica and japonica hybrid rice, variation dynamic, Yongyou 6, ,
