[The virulence shift of rice brown planthopper Nilaparvata lugens (Stal) (Homoptera: Delphacidae) on different rice varieties]
Acta Entomologica Sinica 40 (Supp.), S110-S115
Abstract: Most of the individuals of rice brown planthopper, Nilaparvata lugens (Stål), were unable to feed and survive as well as develop on resistant rice varieties. After being forced to feed on resistant varieties for several generations, the abilities for brown planthopper to infest the varieties changed significantly. But the virulence shifted gradually. It seemed that there was a heritable accumulation from generation to generation. The course and rate of the shift of virulence differed from different resistant varieties as a result of their diversities in both resistant mechanism and genetic background.
