[The biotypes of brown planthopper (Nilaparvata lugens (Stal)) with a view to its control]
Acta Entomologica Sinica 40 (Supp.), S139-S146
Abstract: Results of the present study indicate that the dominant biotype of the brown planthopper (BPH) occured in the 11 Provinces and Autonomous Region of China has changed from biotype 1 to biotype 2 except in Chengdu, Sichuan. Some individuals of the BPH collected in early rice at Simao, Yunnam and Nanning, Guangxi were found to be the same as that of Bangladesh and Sri Landka. They could demage the varieties which contained the genes Bph1 and bph2. Some local varieties and accessions are resistant to biotype 1 and 2 that should be extended for utilization. Most accessions of Oryzae officinalis Wall and the varieties (lines) derived from Ptb33 showed a broad spectrum resistance for cross breeding to control the damage by new biotypes.
