摘要

The brown planthopper (BPH), Nilaparvata lugens, has become a serious threat to rice production in several South, Southeast, and East Asian countries. This paper discusses results of International Rice Brown Planthopper Nursery (IRBPN) screening tests conducted 1975-79 with special reference to understanding biotype variations in BPH and identifying sources of genetic resistance to these biotypes. The number of rice varieties tested ranged from 41 in 1975 to 162 in 1979 and included several traditional tall varieties and improved semidwarf breeding lines.
